strategy.public String getCrossJoinSeparator()
Dialect
Returns the separator to use for defining cross joins when translating HQL queries. <p/> Typically this will be either [<tt> cross join </tt>] or [<tt>, </tt>] <p/> Note that the spaces are important!

public String appendLockHint(LockOptions lockOptions, String tableName)
Dialect
Some dialects support an alternative means to <tt>SELECT FOR UPDATE</tt>, whereby a "lock hint" is appends to the table name in the from clause. <p/> contributed by <a href="http://sourceforge.net/users/heschulz">Helge Schulz</a>
appendLockHint
in class Dialect
lockOptions
- The lock options to applytableName
- The name of the table to which to apply the lock hint.public String applyLocksToSql(String sql, LockOptions aliasedLockOptions, Map<String,String[]> keyColumnNames)
Dialect
Modifies the given SQL by applying the appropriate updates for the specified lock modes and key columns. <p/> The behavior here is that of an ANSI SQL <tt>SELECT FOR UPDATE</tt>. This method is really intended to allow dialects which do not support <tt>SELECT FOR UPDATE</tt> to achieve this in their own fashion.

sql
- the SQL string to modifyaliasedLockOptions
- lock options indexed by aliased table names.keyColumnNames
- a map of key columns indexed by aliased table names.public int registerResultSetOutParameter(CallableStatement statement, int col) throws SQLException
Dialect
Registers a parameter (either OUT, or the new REF_CURSOR param type available in Java 8) capable of
returning ResultSet
by position. Pre-Java 8, registering such ResultSet-returning
parameters varied greatly across database and drivers; hence its inclusion as part of the Dialect contract.
