### New features

* Support `EXPLAIN` statements https://github.com/SeaQL/sea-query/pull/1044
* `#![forbid(unsafe_code)]` in all workspace crates https://github.com/SeaQL/sea-query/pull/930
* Unify `Expr` and `SimpleExpr` as one type. `SimpleExpr` is kept as an alias of `Expr`, but they can now be used interchangeably. There may be a few compile
errors and some clippy warnings, basically just remove the redundant `.into()` https://github.com/SeaQL/sea-query/pull/889
```rust
pub type SimpleExpr = Expr; // !
impl From<Expr> for SimpleExpr { .. } // now removed
```
* New `Iden` type system. Previously, `DynIden` is an alias to `SeaRc<dyn Iden>`, and is lazily rendered. Now, it's an `Cow<'static, str>`, and is eagerly rendered. `SeaRc` is no longer an alias to `Rc` / `Arc`, now is only a unit struct. As such, `Send` / `Sync` is no longer needed. It's still possible to dynamically serialize a String as identifier, see [example usage](https://github.com/SeaQL/sea-schema/blob/master/src/mysql/writer/types.rs). https://github.com/SeaQL/sea-query/pull/909
```rust
pub type DynIden = SeaRc<dyn Iden>;               // old
pub struct DynIden(pub(crate) Cow<'static, str>); // new

pub struct SeaRc<I>(pub(crate) RcOrArc<I>);       // old
pub struct SeaRc;                                 // new
```
* Reworked `TableRef` and `ColumnRef` variants https://github.com/SeaQL/sea-query/pull/927
```rust
// the following variants are collapsed into one:
enum TableRef {
    Table(DynIden),
    SchemaTable(DynIden, DynIden),
    DatabaseSchemaTable(DynIden, DynIden, DynIden),
    TableAlias(DynIden, DynIden),
    SchemaTableAlias(DynIden, DynIden, DynIden),
    DatabaseSchemaTableAlias(DynIden, DynIden, DynIden, DynIden),
    ..
}
// now it's just:
enum TableRef {
    Table(TableName, Option<DynIden>), // optional Alias
    ..
}

pub struct DatabaseName(pub DynIden);
pub struct SchemaName(pub Option<DatabaseName>, pub DynIden);
/// A table name, potentially qualified as [database.][schema.]table
pub struct TableName(pub Option<SchemaName>, pub DynIden);
```
```rust
// before
enum ColumnRef {
    Column(DynIden),
    TableColumn(DynIden, DynIden),
    SchemaTableColumn(DynIden, DynIden, DynIden),
    Asterisk,
    TableAsterisk(DynIden),
}
// now
enum ColumnRef {
    /// A column name, potentially qualified as [database.][schema.][table.]column
    Column(ColumnName),
    /// An `*` expression, potentially qualified as [database.][schema.][table.]*
    Asterisk(Option<TableName>),
}

pub struct ColumnName(pub Option<TableName>, pub DynIden);
```

### Enhancements

* Supports Jiff types except `jiff::Zoned`.
  At the moment this support is only available through the SQLx binder.
  When using SQLx with multiple backends, enable `unimplemented-jiff-sqlx-mysql` to suppress the
  compile-time error. After enabling it, runtime panics may occur.
* Add `Expr::not_exists` https://github.com/SeaQL/sea-query/pull/983
* Add `serde` feature. Currently, enabling it allows `Value` to be serializable https://github.com/SeaQL/sea-query/pull/966
* Add `Keyword::Default` https://github.com/SeaQL/sea-query/pull/965
* Enable `clippy::nursery` https://github.com/SeaQL/sea-query/pull/938
* Removed unnecessary `'static` bounds from type signatures https://github.com/SeaQL/sea-query/pull/921
* `cast_as_quoted` now allows you to qualify the type name. https://github.com/SeaQL/sea-query/pull/922
```rust
let query = Query::select()
    .expr(Func::cast_as_quoted("hello", ("MySchema", "MyType")))
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT CAST('hello' AS "MySchema"."MyType")"#
);
```
* Most `Value` variants are now unboxed (except `BigDecimal` and `Array`). Previously the size is 24 bytes. https://github.com/SeaQL/sea-query/pull/925
```rust
assert_eq!(std::mem::size_of::<Value>(), 32);
```
* Merged `Func`/`Function` and `PgFunc`/`PgFunction`. Now the latter is just an alias of the former https://github.com/SeaQL/sea-query/pull/944
```rust
// old
condition.add(Func::lower(Expr::col(column)).eq(SimpleExpr::FunctionCall(Func::lower(value))))
// new
condition.add(Func::lower(Expr::col(*column)).eq(Func::lower(value)));
```
* `impl From<Expr> for Condition`. Now you can use `Expr` instead of `ConditionExpression`, which has been removed from the public API https://github.com/SeaQL/sea-query/pull/915
```rust
Cond::all().add(ConditionExpression::Expr(Expr::new(..))) // old
Cond::all().add(Expr::new(..))                            // new
```
* Replaced `serial` with `GENERATED BY DEFAULT AS IDENTITY` (Postgres) https://github.com/SeaQL/sea-query/pull/918
To restore legacy behaviour, you can enable the `option-postgres-use-serial` feature flag
```rust
let table = Table::create()
    .table(Char::Table)
    .col(ColumnDef::new(Char::Id).integer().not_null().auto_increment().primary_key())
    .to_owned();

assert_eq!(
    table.to_string(PostgresQueryBuilder),
    [
        r#"CREATE TABLE "character" ("#,
            r#""id" integer GENERATED BY DEFAULT AS IDENTITY NOT NULL PRIMARY KEY,"#,
        r#")"#,
    ].join(" ")
);

// if you needed to support legacy system you can still do:
let table = Table::create()
    .table(Char::Table)
    .col(ColumnDef::new(Char::Id).custom("serial").not_null().primary_key())
    .to_owned();

assert_eq!(
    table.to_string(PostgresQueryBuilder),
    [
        r#"CREATE TABLE "character" ("#,
            r#""id" serial NOT NULL PRIMARY KEY"#,
        r#")"#,
    ].join(" ")
);
```

### Breaking Changes

* Removed inherent `SimpleExpr` methods that duplicate `ExprTrait`. If you encounter the following error, please add `use sea_query::ExprTrait` in scope https://github.com/SeaQL/sea-query/pull/890
```rust
error[E0599]: no method named `like` found for enum `sea_query::Expr` in the current scope
    |
    |         Expr::col((self.entity_name(), *self)).like(s)
    |
    |     fn like<L>(self, like: L) -> Expr
    |        ---- the method is available for `sea_query::Expr` here
    |
    = help: items from traits can only be used if the trait is in scope
help: trait `ExprTrait` which provides `like` is implemented but not in scope; perhaps you want to import it
    |
 -> + use sea_query::ExprTrait;
```
```rust
error[E0308]: mismatched types
  --> src/sqlite/discovery.rs:27:57
   |
   |             .and_where(Expr::col(Alias::new("type")).eq("table"))
   |                                                      -- ^^^^^^^ expected `&Expr`, found `&str`
   |                                                      |
   |                                                      arguments to this method are incorrect
   |
   = note: expected reference `&sea_query::Expr`
              found reference `&'static str`
```
* Added `non_exhaustive` to AST enums. It allows us to add new features and extend the AST without breaking the API. If you encounter the following error,
please add a wildcard match `_ => {..}` https://github.com/SeaQL/sea-query/pull/891
```rust
error[E0004]: non-exhaustive patterns: `&_` not covered
    |
    |     match table_ref {
    |           ^^^^^^^^^ pattern `&_` not covered
    |
note: `TableRef` defined here
    |
    | pub enum TableRef {
    | ^^^^^^^^^^^^^^^^^
    = note: the matched value is of type `&TableRef`
    = note: `TableRef` is marked as non-exhaustive, so a wildcard `_` is necessary to match exhaustively
help: ensure that all possible cases are being handled by adding a match arm with a wildcard pattern or an explicit pattern as shown
    |
    | TableRef::FunctionCall(_, tbl) => SeaRc::clone(tbl),
 -> | &_ => todo!(),
```
* `ExprTrait::eq` collided with `std::cmp::Eq`. If you encounter the following error, please use `std::cmp::PartialEq::eq(a, b)` or
`sea_query::ExprTrait::eq(a, b)` explicitly https://github.com/SeaQL/sea-query/pull/890
```rust
error[E0308]: mismatched types
    |
    |     fn eq(&self, other: &Self) -> bool {
    |                                   ---- expected `bool` because of return type
    |         format!("{:?}", self.0).eq(&format!("{:?}", other.0))
    |         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected `bool`, found `Expr`

For more information about this error, try `rustc --explain E0308`.
error: could not compile `seaography` (lib) due to 1 previous error
```
* The method signature of `Iden::unquoted` is changed. If you're implementing `Iden` manually, you can modify it like below https://github.com/SeaQL/sea-query/pull/909
```rust
error[E0050]: method `unquoted` has 2 parameters but the declaration in trait `types::Iden::unquoted` has 1
  --> src/tests_cfg.rs:31:17
   |
   |     fn unquoted(&self, s: &mut dyn std::fmt::Write) {
   |                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected 1 parameter, found 2
   |
  ::: src/types.rs:63:17
   |
   |     fn unquoted(&self) -> &str;
   |                 ----- trait requires 1 parameter
```
```rust
impl Iden for Glyph {
  - fn unquoted(&self, s: &mut dyn fmt::Write) {
  + fn unquoted(&self) -> &str {
  -     write!(
  -         s,
  -         "{}",
            match self {
                Self::Table => "glyph",
                Self::Id => "id",
                Self::Tokens => "tokens",
            }
  -     )
  -     .unwrap();
    }
}
```
* Removed `ConditionExpression` from the public API. Instead, just convert between `Condition` and `Expr` using `From`/`Into` https://github.com/SeaQL/sea-query/pull/915
```rust
error[E0603]: enum `ConditionExpression` is private
   --> tests/mysql/query.rs:734:20
    |
 >  |     use sea_query::ConditionExpression;
    |                    ^^^^^^^^^^^^^^^^^^^ private enum
 >  |     Cond::all().add(ConditionExpression::Expr(Expr::new(
    |                     ^^^^^^^^^^^^^^^^^^^ use of undeclared type `ConditionExpression`
```
Simply do the following:
```rust
Cond::all().add(Expr::new(..))
```
* Reworked `ColumnRef` variants may cause compile error.
```rust
error[E0277]: the trait bound `fn(std::option::Option<TableName>) -> sea_query::ColumnRef {sea_query::ColumnRef::Asterisk}: IntoColumnRef` is not satisfied
    --> src/executor/query.rs:1599:21
    |
 >  |             .column(ColumnRef::Asterisk)
    |              ------ ^^^^^^^^^^^^^^^^^^^ the trait `sea_query::Iden` is not implemented for fn item `fn(std::option::Option<TableName>) -> sea_query::ColumnRef {sea_query::ColumnRef::Asterisk}`
    |              |
    |              required by a bound introduced by this call

error[E0308]: mismatched types
    --> src/executor/query.rs:1607:54
    |
 >  |                 SimpleExpr::Column(ColumnRef::Column("id".into_iden()))
    |                                    ----------------- ^^^^^^^^^^^^^^^^ expected `ColumnName`, found `DynIden`
    |                                    |
    |                                    arguments to this enum variant are incorrect
```
In the former case `Asterisk` has an additional inner `Option<TableName>`, you can simply put `None`.
```rust
.column(ColumnRef::Asterisk(None))
```
In the latter case, `&'static str` can now be used in most methods that accepts `ColumnRef`.
```rust
Expr::column("id")
```
* Reworked `TableRef` variants may cause compile error.
```rust
error[E0061]: this enum variant takes 2 arguments but 1 argument was supplied
   --> src/entity/relation.rs:526:15
    |
 >  |     from_tbl: TableRef::Table("foo".into_iden()),
    |               ^^^^^^^^^^^^^^^-------------------
    |                              ||
    |                              |expected `TableName`, found `DynIden`
    |                              argument #2 of type `Option<DynIden>` is missing
```
It's recommended to use the `IntoTableRef` trait to convert types instead of constructing AST manually.
```rust
use sea_orm::sea_query::IntoTableRef;

from_tbl: "foo".into_table_ref(),
```
* Replace `dyn <Trait>` with `impl <Trait>` https://github.com/SeaQL/sea-query/pull/982
This gained us up to 10% performance, however it does mean `dyn QueryBuilder` is no longer possible.

### Minor breaking changes

* Changed `Into*` traits (like `IntoCondition`) to be defined as `trait
  IntoCondition: Into<Condition>` and implemented for all `T: Into<Condition>`.
  Now `IntoCondition` and `Into<Condition>` are completely interchangable. But
  you can still use `.into_condition()` for readability.

  If you have manually implemented `Into*` traits, it may cause conflicts. You
  should rewrite your impls as as `impl From<..> for Condition`.

  Full list of changed traits:

    * `IntoColumnDef` https://github.com/SeaQL/sea-query/pull/975
    * `IntoColumnRef` https://github.com/SeaQL/sea-query/pull/959
    * `IntoCondition` https://github.com/SeaQL/sea-query/pull/939
    * `IntoIden` https://github.com/SeaQL/sea-query/pull/973
    * `IntoIndexColumn` https://github.com/SeaQL/sea-query/pull/976
    * `IntoLikeExpr` https://github.com/SeaQL/sea-query/pull/974
    * `IntoTableRef` https://github.com/SeaQL/sea-query/pull/958
    * `IntoTypeRef` https://github.com/SeaQL/sea-query/pull/969
    * `IntoValueTuple` https://github.com/SeaQL/sea-query/pull/960

* Unboxed `Value` variants may cause compile error. Simply remove the `Box` in these cases https://github.com/SeaQL/sea-query/pull/925
```rust
error[E0308]: mismatched types
   --> /home/runner/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/sea-schema-0.17.0-rc.3/src/sqlite/def/table.rs:248:59
    |
 >  | Value::String(Some(Box::new(string_value.to_string()))));
    |               ---- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected `String`, found `Box<String>`
    |               |
    |               arguments to this enum variant are incorrect
```
* Blanket-implemented `SqliteExpr` and `PgExpr` for `T where T: ExprTrait` https://github.com/SeaQL/sea-query/pull/914

  Now you can use database-specific operators with all expression types.
  If you had custom implementations in your own code, some may no longer compile
  and may need to be deleted.
* Replaced `ColumnSpec::Check(Expr)` with `ColumnSpec::Check(Check)` to support named check constraints https://github.com/SeaQL/sea-query/pull/920
* `SelectStatement::cross_join` no longer accepts a condition https://github.com/SeaQL/sea-query/pull/956
* Turned `TypeRef` from an enum into a struct that reuses `TableName`. https://github.com/SeaQL/sea-query/pull/969
* Changed `Expr::TypeName(DynIden)` to `Expr::TypeName(TypeRef)`, which can be
  [qualified](https://github.com/SeaQL/sea-query/issues/827).

  If you manually construct this variant and it no longer compiles, just add
  `.into()`.
* Renamed `QueryBuilder::prepare_simple_expr` to `prepare_expr` https://github.com/SeaQL/sea-query/pull/988
* Changed signature of `Expr::Custom` https://github.com/SeaQL/sea-query/pull/940
```rust
enum Expr {
  - Custom(String),
  + Custom(Cow<'static, str>),
}

fn cust<T>(s: T) -> Self
where
  - T: Into<String>,
  + T: Into<Cow<'static, str>>,
{
    Self::Custom(s.into())
}
```
You many encounter the following error:
```rust
    |         let sql = self.sql.trim();
    |                   ^^^^^^^^ borrowed value does not live long enough
...
    |             Expr::cust_with_values(sql, values.0)
    |             ------------------------------------- argument requires that `self.stmt.sql` is borrowed for `'static`
```
Simply convert the `&str` to `String`:
```rust
let sql = self.sql.trim().to_owned();
```

    .from(Char::Table)
    .cond_where(
        Expr::col((Glyph::Table, Glyph::Image))
            .eq(Expr::col((Char::Table, Char::UserData))),
    )
    .to_owned();

* `Expr::cust`, `Expr::cust_with_values`, `Expr::cust_with_expr`, `Expr::cust_with_exprs`, `TableForeignKey::name`, `ForeignKeyCreateStatement::name`, `ForeignKeyDropStatement::name`, `TableIndex::name`, `IndexCreateStatement::name`, `IndexDropStatement::name`, `SqlWriterValues::new`, `ColumnType::custom`, `TableCreateStatement::engine`, `TableCreateStatement::collate`, `TableCreateStatement::character_set`, `TableRef::new`, `LikeExpr::str` now accept `T: Into<String>` https://github.com/SeaQL/sea-query/pull/594
* `OnConflict::values` and `OnConflict::update_columns` will append the new values keeping the old values intact instead of erasing them https://github.com/SeaQL/sea-query/pull/609
* As part of https://github.com/SeaQL/sea-query/pull/620, `SeaRc` now becomes a wrapper type.
If you used `SeaRc` for something other than `dyn Iden`, you now have to use `RcOrArc`.
However be reminded that it is not an intended use of the API anyway.
```rust
// new definition
struct SeaRc<I>(RcOrArc<I>);
// remains unchanged
type DynIden = SeaRc<dyn Iden>;

// if you did:
let _: DynIden = Rc::new(Alias::new("char"));
// replace with:
let _: DynIden = SeaRc::new(Alias::new("char"));
```
* Added new type `Quote` and changed the `Iden` trait:
```rust
struct Quote(pub(crate) u8, pub(crate) u8);

trait Iden {
    // then:
    fn prepare(&self, s: &mut dyn fmt::Write, q: char);
    // now:
    fn prepare(&self, s: &mut dyn fmt::Write, q: Quote);

    // then:
    fn quoted(&self, q: char) -> String;
    // now:
    fn quoted(&self, q: Quote) -> String;
}
```

        .to_string(PostgresQueryBuilder),
    r#"SELECT WHERE "id" = 1 OR "id" = 2 OR "id" = 3"#

// Now: will always conjoin with `AND`
assert_eq!(
    Query::select()
        .cond_where(Expr::col(Glyph::Id).eq(1))
        .cond_where(any![Expr::col(Glyph::Id).eq(2), Expr::col(Glyph::Id).eq(3)])
        .to_owned()
        .to_string(PostgresQueryBuilder),
    r#"SELECT WHERE "id" = 1 AND ("id" = 2 OR "id" = 3)"#
);
// Now: so they are now equivalent
assert_eq!(
    Query::select()
        .cond_where(any![Expr::col(Glyph::Id).eq(2), Expr::col(Glyph::Id).eq(3)])
        .cond_where(Expr::col(Glyph::Id).eq(1))
        .to_owned()
        .to_string(PostgresQueryBuilder),

```rust
use sea_query::EscapeBuilder;

let string: String = MySqlQueryBuilder.escape_string(r#" "abc" "#);
let string: String = MysqlQueryBuilder.unescape_string(r#" \"abc\" "#);
```

* Replace `Value::Ipv4Network` and `Value::Ipv6Network`  to `Value::IpNetwork` https://github.com/SeaQL/sea-query/pull/364

* Remove some redundant feature flags `postgres-chrono`, `postgres-json`, `postgres-uuid`, `postgres-time`. Use the `with-*` equivalence

### Bug fixes

* Fix arguments when nesting custom expressions https://github.com/SeaQL/sea-query/pull/333
* Fix clippy warnings for manual map https://github.com/SeaQL/sea-query/pull/337

### Breaking Changes

* Introducing a dedicated `ReturningClause` instead of reusing `Select` on `returning`: https://github.com/SeaQL/sea-query/pull/317

```rust
.returning(Query::select().column(Glyph::Id).take()) // before
.returning(Query::returning().columns([Glyph::Id])) // now
```

* In #333, the custom expression API changed for Postgres, users should change their placeholder from `?` to Postgres's `$N`

```rust
let query = Query::select()
    .columns([Char::Character, Char::SizeW, Char::SizeH])
    .from(Char::Table)
    .and_where(Expr::col(Char::Id).eq(1))
    .and_where(Expr::cust_with_values("6 = $2 * $1", vec![3, 2]).into())
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT "character", "size_w", "size_h" FROM "character" WHERE "id" = 1 AND 6 = 2 * 3"#
);
```

As a side effect, `??` is no longer needed for escaping `?`

```rust
let query = Query::select()
    .expr(Expr::cust_with_values(
        "data @? ($1::JSONPATH)",
        vec!["hello"],
    ))
    .to_owned();

assert_eq!(
    query.to_string(PostgresQueryBuilder),
    r#"SELECT data @? ('hello'::JSONPATH)"#
);
```

* In #314, `ColumnType`'s `Binary(Option<u32>)` changed to `Binary(BlobSize)`, so if you used `Binary(None)` before, you should change to `Binary(BlobSize::Blob(None))`

**Full Changelog**: https://github.com/SeaQL/sea-query/compare/0.24.0...0.25.0

## 0.15.0 - 2021-08-21

+ [[#107]] Revamp `Value` to typed null value
+ Added `BigDecimal` support

The `Value::Null` variant is removed. You have to use a specific variant with a `None`.

Before:

```rust
Query::insert()
    .values_panic(vec![
        Value::Null,
        2.1345.into(),
    ])
```

After:

```rust
Query::insert()
    .values_panic(vec![
        Value::String(None),
        2.1345.into(),
    ])
```

Since we cannot handle the generic `Null` value on JSON, we removed the `json` method on `InsertStatement` and `UpdateStatement`. The following NO LONGER WORKS:

```rust
let query = Query::insert()
    .into_table(Glyph::Table)
    .json(json!({
        "aspect": 2.1345,
        "image": "24B",
    }));
```

```rust
let query = Query::update()
    .table(Glyph::Table)
    .json(json!({
        "aspect": 2.1345,
        "image": "235m",
    }));
```

In addition, if you constructed `Value` manually before (instead of using `into()` which is unaffected), you have to wrap them in an `Option`:

Before:

```rust
let (sql, values) = query.build(PostgresQueryBuilder);
assert_eq!(
	values,
	Values(vec![Value::String(Box::new("A".to_owned())), Value::Int(1), Value::Int(2), Value::Int(3)]))
);
```

After:

```rust
let (sql, values) = query.build(PostgresQueryBuilder);
assert_eq!(
	values,
	Values(vec![Value::String(Some(Box::new("A".to_owned()))), Value::Int(Some(1)), Value::Int(Some(2)), Value::Int(Some(3))]))
);
```
