Method Summary

Methods
Modifier and Type	Method and Description
`String`	`appendIdentitySelectToInsert(String insertSQL)` Provided we `Dialect.supportsInsertSelectIdentity()`, then attach the "select identity" clause to the insert statement.
`String`	`appendLockHint(LockMode mode, String tableName)` Some dialects support an alternative means to `SELECT FOR UPDATE`, whereby a "lock hint" is appends to the table name in the from clause.
`String`	`applyLocksToSql(String sql, LockOptions aliasedLockOptions, Map keyColumnNames)` Modifies the given SQL by applying the appropriate updates for the specified lock modes and key columns.
`boolean`	`areStringComparisonsCaseInsensitive()` By default, Sybase string comparisons are case-insensitive.
`boolean`	`doesReadCommittedCauseWritersToBlockReaders()` For the underlying database, is READ_COMMITTED isolation implemented by forcing readers to wait for write locks to be released?
