DialectReturn the limit that the underlying database places on the number of elements in an IN predicate.
If the database defines no such limits, simply return zero or less-than-zero.
getInExpressionCountLimit in class Dialectprotected SqlTypeDescriptor getSqlTypeDescriptorOverride(int sqlCode)
DialectReturns the SqlTypeDescriptor that should be used to handle the given JDBC type code. Returns
null if there is no override.

getForUpdateString in class Dialectpublic String appendLockHint(LockOptions lockOptions, String tableName)
DialectSome 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 DialectlockOptions - 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)
DialectModifies 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.
applyLocksToSql in class Dialectsql - 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
DialectRegisters 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.
registerResultSetOutParameter in class Dialectstatement - The callable statement.col - The bind position at which to register the output param.SQLException - Indicates problems registering the param.public ResultSet getResultSet(CallableStatement ps) throws SQLException
DialectGiven a callable statement previously processed by Dialect.registerResultSetOutParameter(java.sql.CallableStatement, int),
extract the ResultSet from the OUT parameter.
getResultSet in class Dialectps - The callable statement.SQLException - Indicates problems extracting the result set.public boolean supportsCurrentTimestampSelection()
DialectDoes this dialect support a way to retrieve the database’s current timestamp value?
supportsCurrentTimestampSelection in class Dialectpublic boolean isCurrentTimestampSelectStringCallable()
DialectShould the value returned by Dialect.getCurrentTimestampSelectString()
be treated as callable. Typically this indicates that JDBC escape
syntax is being used…

is callable; false otherwise.public String getCurrentTimestampSelectString()
DialectRetrieve the command used to retrieve the current timestamp from the database.
