}

Required Methods§

fn prepare_index_create_statement( &self, create: &IndexCreateStatement, sql: &mut dyn SqlWriter, )

Translate IndexCreateStatement into SQL statement.

fn prepare_table_ref_index_stmt( &self, table_ref: &TableRef, sql: &mut dyn SqlWriter, )

Translate TableRef into SQL statement.

fn prepare_index_drop_statement( &self, drop: &IndexDropStatement, sql: &mut dyn SqlWriter, )

Translate IndexDropStatement into SQL statement.

Provided Methods§

fn prepare_table_index_expression( &self, create: &IndexCreateStatement, sql: &mut dyn SqlWriter, )

Translate IndexCreateStatement into SQL expression. This is the default implementation for PostgresQueryBuilder and SqliteQueryBuilder. MysqlQueryBuilder overrides this default implementation.
