Method Detail
-
getNoColumnsInsertString
public java.lang.String getNoColumnsInsertString()
Sybase Anywhere syntax would require a "DEFAULT" for each column specified, but I suppose Hibernate use this syntax only with tables with just 1 column The fragment used to insert a row without specifying any column values. This is not possible on some databases.- Overrides:
getNoColumnsInsertStringin classDialect- Returns:
- The appropriate empty values clause.
-
dropConstraints
public boolean dropConstraints()
ASA does not require to drop constraint before dropping tables, so disable it. NOTE : Also, the DROP statement syntax used by Hibernate to drop constraints is not compatible with ASA. Do we need to drop constraints before dropping tables in this dialect?- Overrides:
dropConstraintsin classDialect- Returns:
- True if constraints must be dropped prior to dropping the table; false otherwise.
-
getIdentityColumnSupport
public IdentityColumnSupport getIdentityColumnSupport()
Description copied from class:DialectGet the appropriateIdentityColumnSupport- Returns:
- the IdentityColumnSupport
-
getSqlTypeDescriptorOverride
protected SqlTypeDescriptor getSqlTypeDescriptorOverride(int sqlCode)
Description copied from class:DialectReturns theSqlTypeDescriptorthat should be used to handle the given JDBC type code. Returnsnullif there is no override.- Overrides:
getSqlTypeDescriptorOverridein classSybaseDialect- Parameters:
sqlCode- ATypesconstant indicating the SQL column type- Returns:
- The
SqlTypeDescriptorto use as an override, ornullif there is no override.
-
getAddColumnString
public java.lang.String getAddColumnString()
Description copied from class:DialectThe syntax used to add a column to a table (optional).- Overrides:
getAddColumnStringin classDialect- Returns:
- The "add column" fragment.
-
qualifyIndexName
public boolean qualifyIndexName()
Description copied from class:DialectDo we need to qualify index names with the schema name?- Overrides:
qualifyIndexNamein classDialect- Returns:
- boolean
-
getForUpdateString
public java.lang.String getForUpdateString()
Description copied from class:DialectGet the string to append to SELECT statements to acquire locks for this dialect.- Overrides:
getForUpdateStringin classDialect- Returns:
- The appropriate FOR UPDATE clause string.
-
appendLockHint
public java.lang.String appendLockHint(LockOptions lockOptions, java.lang.String tableName)
Description copied from class:DialectSome dialects support an alternative means to SELECT FOR UPDATE, whereby a "lock hint" is appended to the table name in the from clause. contributed by Helge Schulz- Overrides:
appendLockHintin classDialect- Parameters:
lockOptions- The lock options to applytableName- The name of the table to which to apply the lock hint.- Returns:
- The table with any required lock hints.
-
applyLocksToSql
public java.lang.String applyLocksToSql(java.lang.String sql, LockOptions aliasedLockOptions, java.util.Map<java.lang.String,java.lang.String[]> keyColumnNames)Description copied from class:DialectModifies the given SQL by applying the appropriate updates for the specified lock modes and key columns. The behavior here is that of an ANSI SQL SELECT FOR UPDATE. This method is really intended to allow dialects which do not support SELECT FOR UPDATE to achieve this in their own fashion.- Overrides:
applyLocksToSqlin classDialect- Parameters:
sql- the SQL string to modifyaliasedLockOptions- lock options indexed by aliased table names.keyColumnNames- a map of key columns indexed by aliased table names.- Returns:
- the modified SQL string.
-
registerResultSetOutParameter
public int registerResultSetOutParameter(java.sql.CallableStatement statement, int col) throws java.sql.SQLExceptionDescription copied from class:DialectRegisters a parameter (either OUT, or the new REF_CURSOR param type available in Java 8) capable of returningResultSet*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.- Overrides:
registerResultSetOutParameterin classDialect- Parameters:
statement- The callable statement.col- The bind position at which to register the output param.- Returns:
- The number of (contiguous) bind positions used.
- Throws:
java.sql.SQLException- Indicates problems registering the param.
-
getResultSet
public java.sql.ResultSet getResultSet(java.sql.CallableStatement ps) throws java.sql.SQLExceptionDescription copied from class:DialectGiven a callable statement previously processed byDialect.registerResultSetOutParameter(java.sql.CallableStatement, int), extract theResultSetfrom the OUT parameter.- Overrides:
getResultSetin classDialect- Parameters:

- Throws:
java.sql.SQLException- Indicates problems extracting the result set.
-
