Constructor and Description |
---|
SybaseAnywhereDialect() |
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(LockOptions lockOptions,
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<String,String[]> keyColumnNames)
Modifies the given SQL by applying the appropriate updates for the specified
lock modes and key columns.
|
boolean |
doesReadCommittedCauseWritersToBlockReaders()
For the underlying database, is READ_COMMITTED isolation implemented by
forcing readers to wait for write locks to be released?
|
boolean |
doesRepeatableReadCauseReadersToBlockWriters()
For the underlying database, is REPEATABLE_READ isolation implemented by
forcing writers to wait for read locks to be released?
|
boolean |
dropConstraints()
ASA does not require to drop constraint before dropping tables, so disable it.
|
boolean |
dropTemporaryTableAfterUse()
Do we need to drop the temporary table after use?
|
String |
generateTemporaryTableName(String baseTableName)
Generate a temporary table name given the base table.
|
String |
getAddColumnString()
The syntax used to add a column to a table (optional).
|
String |
getCurrentTimestampSelectString()
Retrieve the command used to retrieve the current timestamp from the
database.
|
String |
getForUpdateString()
Get the string to append to SELECT statements to acquire locks
for this dialect.
|
String |
getIdentityColumnString()
The syntax used during DDL to define a column as being an IDENTITY.
|
String |
getIdentitySelectString()
Get the select command to use to retrieve the last generated IDENTITY
value.
|
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
|
ResultSet |
getResultSet(CallableStatement ps)
Given a callable statement previously processed by
Dialect.registerResultSetOutParameter(java.sql.CallableStatement, int) ,
extract the ResultSet from the OUT parameter. |
String |
getSelectGUIDString()
Get the command used to select a GUID from the underlying database.
|
boolean |
isCurrentTimestampSelectStringCallable()
Should the value returned by
Dialect.getCurrentTimestampSelectString()
be treated as callable. |
boolean |
qualifyIndexName()
Do we need to qualify index names with the schema name?
|
int |
registerResultSetOutParameter(CallableStatement statement,
int col)
Registers an OUT parameter which will be returning a
ResultSet . |
boolean |
supportsCurrentTimestampSelection()
Does this dialect support a way to retrieve the database's current
timestamp value?
|
boolean |
supportsEmptyInList()
Does this dialect support empty IN lists?
For example, is [where XYZ in ()] a supported construct?
|
boolean |
supportsExistsInSelect()
Does the dialect support an exists statement in the select clause?
|
boolean |
supportsIdentityColumns()
Does this dialect support identity column key generation?
|
boolean |
supportsInsertSelectIdentity()
Does the dialect support some form of inserting and selecting
the generated IDENTITY value all in the same statement.
|
boolean |
supportsTemporaryTables()
Does this dialect support temporary tables?
|
boolean |
supportsTupleDistinctCounts()
Does this dialect support `count(distinct a,b)`?
|
boolean |
supportsTuplesInSubqueries()
Does this dialect support tuples in subqueries? Ex:
delete from Table1 where (col1, col2) in (select col1, col2 from Table2)
|
boolean |
supportsUnionAll()
Does this dialect support UNION ALL, which is generally a faster
variant of UNION?
