## unreleased
|
|
|
|
- Remove `SqlEngine.withOptions` constructor - just use the regular one
|
|
- Changed `SelectStatement.from` from `List<Queryable>` to `Queryable?`. Selecting from multiple
|
|
tables with a comma will now be parsed as a `JoinClause`.
|
|
- Changed `SelectStatementAsSource.statement` from `SelectStatement` to `BaseSelectStatement` and allow
|
|
compound select statements to appear in a `FROM` clause
|
|
- Support the `VALUES` clause as select statement
|
|
- The new type inference engine is now enabled by default and the `enableExperimentalTypeInference` option
|
|
has been removed. To continue using the old engine, the `useLegacyTypeInference` flag can be used.
|
|
|
|
## 0.7.0
|
|
|
|
- New feature: Table valued functions.
|
|
- __Breaking__: Removed the `enableJson1` parameter on `EngineOptions`. Add a `Json1Extension` instance
|
|
to `enabledExtensions` instead.
|
|
- Parse `rowid` as a valid reference when needed (`SELECT rowid FROM tbl` is now parsed correctly)
|
|
- Parse `CURRENT_TIME`, `CURRENT_DATE` and `CURRENT_TIMESTAMP`
|
|
- Parse `UPSERT` clauses for insert statements
|
|
|
|
## 0.6.0
|
|
|
|
- __Breaking:__ Added an argument type and argument to the visitor classes
|
|
- Experimental new type inference algorithm
|
|
(`SqlEngine.withOptions(EngineOptions(enableExperimentalTypeInference: true))`)
|
|
- Support `CAST` expressions and the `ISNULL` / `NOTNULL` postfixes
|
|
- Support parsing `CREATE TRIGGER` statements
|
|
- Support parsing `CREATE INDEX` statements
|
|
|
|
## 0.5.0
|
|
- Optionally support the `json1` module
|
|
- Optionally support the `fts5` module
|
|
|
|
## 0.4.0
|
|
- Support common table expressions
|
|
- Handle special `rowid`, `oid`, `__rowid__` references
|
|
- Support references to `sqlite_master` and `sqlite_sequence` tables
|
|
|
|
## 0.3.0
|
|
- parse compound select statements
|
|
- scan comment tokens
|
|
- experimental auto-complete engine (only supports a tiny subset based on the grammar only)
|
|
- some features that are specific to moor
|
|
|
|
__0.3.0+1__: Accept `\r` characters as whitespace
|
|
|
|
## 0.2.0
|
|
- Parse `CREATE TABLE` statements
|
|
- Extract schema information from parsed create table statements with `SchemaFromCreateTable`.
|
|
|
|
## 0.1.2
|
|
- parse `COLLATE` expressions
|
|
- fix wrong order in parsed `LIMIT` clauses
|
|
|
|
## 0.1.1
|
|
Attempt to recognize when a bound variable should be an array (eg. in `WHERE x IN ?`).
|
|
Also fixes a number of parsing bugs:
|
|
- Parses tuples, proper type resolution for `IN` expressions
|
|
- Don't resolve references to tables that don't appear in the surrounding statement.
|
|
- Parse joins without any additional operator, e.g. `table1 JOIN table2` instead of
|
|
`table1 CROSS JOIN table2`.
|
|
- Parser now complains when parsing a query doesn't fully consume the input
|
|
|
|
## 0.1.0
|
|
Initial version, can parse most statements but not `DELETE`, common table expressions and other
|
|
advanced features. |
