java.lang.Object org.hibernate.dialect.Dialect org.hibernate.dialect.TimesTenDialect
public class TimesTenDialect
A SQL dialect for TimesTen 5.1. Known limitations: joined-subclass support because of no CASE support in TimesTen No support for subqueries that includes aggregation - size() in HQL not supported - user queries that does subqueries with aggregation No CLOB/BLOB support No cascade delete support. No Calendar support No support for updating primary keys.

Generate a temporary table name given the base table. |
String |
getAddColumnString()
The syntax used to add a column to a table (optional). |
String |
getCreateSequenceString(String sequenceName)
Typically dialects which support sequences can create a sequence with a single command. |
String |
getCreateTemporaryTablePostfix()
Get any fragments needing to be postfixed to the command for temporary table creation. |
String |
getCreateTemporaryTableString()
Command used to create a temporary table. |
String |
getCrossJoinSeparator()
Get the separator to use for defining cross joins when translating HQL queries. |
String |
getCurrentTimestampSelectString()
Retrieve the command used to retrieve the current timestamp from the database. |
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 |
getLimitString(String querySelect,
int offset,
int limit)
Given a limit and an offset, apply the limit clause to the query. |
LockingStrategy |
getLockingStrategy(Lockable lockable,
LockMode lockMode)
Get a strategy instance which knows how to acquire a database-level lock of the specified mode for this dialect. |
String |
getQuerySequencesString()
Get the select command used retrieve the names of all sequences. |
String |
getSelectSequenceNextValString(String sequenceName)
Generate the select expression fragment that will retrieve the next value of a sequence as part of another (typically DML) statement. |
String |
getSequenceNextValString(String sequenceName)
Generate the appropriate select statement to to retrieve the next value of a sequence. |
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? |
boolean |
supportsColumnCheck()
Does this dialect support column-level check constraints? |
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 |
supportsLimit()
Does this dialect support some form of limiting query results via a SQL clause? |
boolean |
supportsLimitOffset()
Does this dialect's LIMIT support (if any) additionally support specifying an offset? |
boolean |
supportsSequences()
Does this dialect support sequences? |
boolean |
supportsTableCheck()
Does this dialect support table-level check constraints? |
boolean |
supportsTemporaryTables()
Does this dialect support temporary tables? |

boolean |
supportsUniqueConstraintInCreateAlterTable()
Does this dialect support adding Unique constraints via create and alter table ? |
boolean |
supportsVariableLimit()
Does this dialect support bind variables (i.e., prepared statement parameters) for its limit/offset? |
boolean |
useMaxForLimit()
Does the LIMIT clause take a "maximum" row number instead of a total number of returned rows? This is easiest understood via an example. |
