Method Summary | |

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. |
LimitHandler |
buildLimitHandler(String sql,
RowSelection selection)
Build delegate managing LIMIT clause. |
SQLExceptionConversionDelegate |
buildSQLExceptionConversionDelegate()
Build an instance of a SQLExceptionConversionDelegate for
interpreting dialect-specific error or SQLState codes. |
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 |
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 |
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 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? |

public LimitHandler buildLimitHandler(String sql, RowSelection selection)
Dialect
buildLimitHandler
in class Dialect
sql
- SQL query.selection
- Selection criteria. null
in case of unlimited number of rows.
public String appendLockHint(LockOptions lockOptions, String tableName)
Dialect
appendLockHint
in class SQLServerDialect
lockOptions
- The lock options to applytableName
- The name of the table to which to apply the lock hint.
public SQLExceptionConversionDelegate buildSQLExceptionConversionDelegate()
Dialect
SQLExceptionConversionDelegate
for
interpreting dialect-specific error or SQLState codes.
When Dialect.buildSQLExceptionConverter()
returns null, the default
SQLExceptionConverter
is used to interpret SQLState and
error codes. If this method is overridden to return a non-null value,
the default SQLExceptionConverter
will use the returned
SQLExceptionConversionDelegate
in addition to the following
standard delegates:
