dropConstraintsin classDialect- Returns:
- True if constraints must be dropped prior to dropping the table; false otherwise.
-
qualifyIndexName
public boolean qualifyIndexName()
Description copied from class:DialectDo we need to qualify index names with the schema name?- Overrides:
qualifyIndexNamein classDialect- Returns:

getSelectSequenceNextValString
public String getSelectSequenceNextValString(String sequenceName)
Description copied from class:DialectGenerate the select expression fragment that will retrieve the next value of a sequence as part of another (typically DML) statement. This differs fromDialect.getSequenceNextValString(String)in that this should return an expression usable within another statement.- Overrides:

- The "nextval" fragment.
-
getSequenceNextValString
public String getSequenceNextValString(String sequenceName)

getSequenceNextValStringin classDialect- Parameters:
sequenceName- the name of the sequence- Returns:
- String The "nextval" select string.
-
getCreateSequenceString
public String getCreateSequenceString(String sequenceName)
Description copied from class:DialectTypically dialects which support sequences can create a sequence with a single command. This is convenience form ofDialect.getCreateSequenceStrings(java.lang.String)to help facilitate that. Dialects which support sequences and can create a sequence in a single command need *only* override this method. Dialects which support sequences but require multiple commands to create a sequence should instead overrideDialect.getCreateSequenceStrings(java.lang.String).- Overrides:
getCreateSequenceStringin classDialect- Parameters:
sequenceName- The name of the sequence- Returns:
- The sequence creation command
-
getDropSequenceString
public String getDropSequenceString(String sequenceName)
Description copied from class:DialectTypically dialects which support sequences can drop a sequence with a single command. This is convenience form ofDialect.getDropSequenceStrings(java.lang.String)to help facilitate that. 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 overrideDialect.getDropSequenceStrings(java.lang.String).- Overrides:
getDropSequenceStringin classDialect- Parameters:
sequenceName- The name of the sequence- Returns:
- The sequence drop commands
-
getQuerySequencesString
public String getQuerySequencesString()
Description copied from class:DialectGet the select command used retrieve the names of all sequences.- Overrides:
getQuerySequencesStringin classDialect- Returns:
- The select command; or null if sequences are not supported.

public SequenceInformationExtractor getSequenceInformationExtractor()
- Overrides:
getSequenceInformationExtractorin classDialect
-
createOuterJoinFragment
public JoinFragment createOuterJoinFragment()
Description copied from class:DialectCreate aJoinFragmentstrategy responsible for handling this dialect's variations in how joins are handled.- Overrides:
createOuterJoinFragmentin classDialect- Returns:
- This dialect's
JoinFragmentstrategy.
-
getCrossJoinSeparator
public String getCrossJoinSeparator()
Description copied from class:DialectReturns the separator to use for defining cross joins when translating HQL queries. Typically this will be either [ cross join ] or [, ] Note that the spaces are important!- Overrides:
getCrossJoinSeparatorin classDialect- Returns:
- The cross join separator
-
getForUpdateString
public 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.
-
supportsColumnCheck
public boolean supportsColumnCheck()
Description copied from class:DialectDoes this dialect support column-level check constraints?- Overrides:
supportsColumnCheckin classDialect- Returns:
- True if column-level CHECK constraints are supported; false otherwise.
-
supportsTableCheck
public boolean supportsTableCheck()
Description copied from class:DialectDoes this dialect support table-level check constraints?- Overrides:
supportsTableCheckin classDialect- Returns:
- True if table-level CHECK constraints are supported; false otherwise.
-
getLimitHandler
public LimitHandler getLimitHandler()
Description copied from class:DialectReturns the delegate managing LIMIT clause.- Overrides:
getLimitHandlerin classDialect- Returns:
- LIMIT clause delegate.
-
supportsLimitOffset
public boolean supportsLimitOffset()
Description copied from class:DialectDoes this dialect's LIMIT support (if any) additionally support specifying an offset?- Overrides:
supportsLimitOffsetin classDialect- Returns:
- True if the dialect supports an offset within the limit support.
-
supportsVariableLimit
public boolean supportsVariableLimit()
Description copied from class:DialectDoes this dialect support bind variables (i.e., prepared statement parameters) for its limit/offset?- Overrides:
supportsVariableLimitin classDialect- Returns:
- True if bind variables can be used; false otherwise.
-
supportsLimit
public boolean supportsLimit()
Description copied from class:DialectDoes this dialect support some form of limiting query results via a SQL clause?- Overrides:
supportsLimitin classDialect- Returns:
- True if this dialect supports some form of LIMIT.
-
useMaxForLimit
public boolean useMaxForLimit()
Description copied from class:DialectDoes the LIMIT clause take a "maximum" row number instead of a total number of returned rows? This is easiest understood via an example. Consider you have a table with 20 rows, but you only want to retrieve rows number 11 through 20. Generally, a limit with offset would say that the offset = 11 and the limit = 10 (we only want 10 rows at a time); this is specifying the total number of returned rows. Some dialects require that we instead specify offset = 11 and limit = 20, where 20 is the "last" row we want relative to offset (i.e. total number of rows = 20 - 11 = 9) So essentially, is limit relative from offset? Or is limit absolute?- Overrides:
useMaxForLimitin classDialect- Returns:
- True if limit is relative from offset; false otherwise.
-
getLimitString
public String getLimitString(String querySelect, int offset, int limit)
Description copied from class:DialectGiven a limit and an offset, apply the limit clause to the query.- Overrides:
getLimitStringin classDialect- Parameters:
querySelect- The query to which to apply the limit.offset- The offset of the limitlimit- The limit of the limit ;)- Returns:
- The modified query statement with the limit applied.
-
supportsCurrentTimestampSelection

Description copied from class:DialectDoes this dialect support a way to retrieve the database's current timestamp value?- Overrides:
supportsCurrentTimestampSelectionin classDialect- Returns:
- True if the current timestamp can be retrieved; false otherwise.
-
getCurrentTimestampSelectString
public String getCurrentTimestampSelectString()
Description copied from class:DialectRetrieve the command used to retrieve the current timestamp from the database.- Overrides:
getCurrentTimestampSelectStringin classDialect- Returns:
- The command.
-
isCurrentTimestampSelectStringCallable
public boolean isCurrentTimestampSelectStringCallable()
Description copied from class:DialectShould the value returned byDialect.getCurrentTimestampSelectString()be treated as callable. Typically this indicates that JDBC escape syntax is being used...- Overrides:
isCurrentTimestampSelectStringCallablein classDialect- Returns:
- True if the
Dialect.getCurrentTimestampSelectString()return is callable; false otherwise.
-
getDefaultMultiTableBulkIdStrategy
public MultiTableBulkIdStrategy getDefaultMultiTableBulkIdStrategy()
- Overrides:
getDefaultMultiTableBulkIdStrategyin classDialect

getLockingStrategyin classDialect- Parameters:
lockable- The persister for the entity to be locked.lockMode- The type of lock to be acquired.- Returns:
- The appropriate locking strategy.
-
supportsEmptyInList
public boolean supportsEmptyInList()
Description copied from class:DialectDoes this dialect support empty IN lists? For example, is [where XYZ in ()] a supported construct?- Overrides:
