SQLServer2016Dialect() |
Modifier and Type | Method and Description |
---|---|
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.
|
String |
getAddColumnString()
The syntax used to add a column to a table (optional).
|
MultiTableBulkIdStrategy |
getDefaultMultiTableBulkIdStrategy() |
String[] |
getDropSchemaCommand(String schemaName)
Get the SQL command used to drop the named schema
|
String |
getDropSequenceString(String sequenceName)
Typically dialects which support sequences can drop a sequence
with a single command.
|
String |
getForUpdateString()
Get the string to append to SELECT statements to acquire locks
for this dialect.
|
String |
getNullColumnString()
The keyword used to specify a nullable 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 a parameter (either OUT, or the new REF_CURSOR param type available in Java 8) capable of
returning
ResultSet *by position*. |
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 |
supportsIfExistsBeforeConstraintName()
For dropping a constraint with an "alter table", can the phrase "if exists" be applied before the constraint name?
NOTE : Only one or the other (or neither) of this and
Dialect.supportsIfExistsAfterConstraintName() should return true |
boolean |
supportsIfExistsBeforeTableName()
For dropping a table, can the phrase "if exists" be applied before the table name?
NOTE : Only one or the other (or neither) of this and
Dialect.supportsIfExistsAfterTableName() should return true |
boolean |
supportsPartitionBy()
Does the underlying database support partition by
|
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?

Dialects which support sequences and can drop a sequence in a
single command need *only* override this method. Dialects
which support sequences but require multiple commands to drop
a sequence should instead override Dialect.getDropSequenceStrings(java.lang.String)
