defaultSqlQuery :: SqlGenerator -> PrimQuery -> SqlSelect Source
Arguments
| :: SqlGenerator | |
| -> TableName | Name of the table to update. |
| -> [PrimExpr] | Conditions which must all be true for a row to be updated. |
| -> Assoc | Update the data with this. |
| -> SqlUpdate |
Creates a SqlUpdate. Corresponds to the SQL statement
UPDATE which updates data in a table.
Arguments
| :: SqlGenerator | |
| -> TableName | Name of the table |
| -> [PrimExpr] | Criteria which must all be true for a row to be deleted. |
| -> SqlDelete |
Creates a SqlDelete. Corresponds to the SQL statement
DELETE which deletes rows in a table.
Arguments
| :: SqlGenerator | |
| -> TableName | Name of the table |
| -> Assoc | What to insert. |
| -> SqlInsert |
Creates a SqlInsert.
Arguments
| :: SqlGenerator | |
| -> TableName | Name of the table |
| -> PrimQuery | What to insert |
| -> SqlInsert |
Creates a SqlInsert. Corresponds to the SQL statement
INSERT INTO which is used to insert new rows in a table.
Arguments
| :: SqlGenerator | |
| -> String | name of the database. |
| -> SqlCreate |
Use this to create a SqlCreate data type corresponding to
the SQL statement CREATE DATABASE which creates a new database.
Arguments
| :: SqlGenerator | |
| -> TableName | name of the table to be created. |
| -> [(Attribute, FieldDesc)] | Column descriptions |
| -> SqlCreate |
Use this to create a SqlCreate data type corresponding to
the SQL statement CREATE which creates a new table.
defaultSqlDropDB :: SqlGenerator -> String -> SqlDrop Source
Creates a SqlDrop that delete the database with the
name given as the first argument.
defaultSqlDropTable :: SqlGenerator -> TableName -> SqlDrop Source
Creates a SqlDrop that delete the database named
in the first argument.
defaultSqlTable :: SqlGenerator -> TableName -> Scheme -> SqlSelect Source
defaultSqlProject :: SqlGenerator -> Assoc -> SqlSelect -> SqlSelect Source
defaultSqlRestrict :: SqlGenerator -> PrimExpr -> SqlSelect -> SqlSelect Source
defaultSqlBinary :: SqlGenerator -> RelOp -> SqlSelect -> SqlSelect -> SqlSelect Source
defaultSqlGroup :: SqlGenerator -> Assoc -> SqlSelect -> SqlSelect Source
Ensures the groupby value on the SqlSelect either preserves existing grouping or that it will group on all columns (i.e, Mark == All).
defaultSqlSpecial :: SqlGenerator -> SpecialOp -> SqlSelect -> SqlSelect Source
defaultSqlExpr :: SqlGenerator -> PrimExpr -> SqlExpr Source
defaultSqlLiteral :: SqlGenerator -> Literal -> String Source
defaultSqlType :: SqlGenerator -> FieldType -> SqlType Source
defaultSqlQuote :: SqlGenerator -> String -> String Source
Utilities
toSqlSelect :: SqlSelect -> SqlSelect Source
Make sure our SqlSelect statement is really a SqlSelect and not another constructor.
