Modifier and Type | Method and Description |
---|---|
ValueReadQuery |
buildSelectQueryForIdentity()
INTERNAL:
Returns query used to read back the value generated by Identity.
|
ValueReadQuery |
buildSelectQueryForSequenceObject(java.lang.String seqName,
java.lang.Integer size)
INTERNAL:
Returns query used to read value generated by sequence object (like Oracle sequence).
|
int |
computeMaxRowsForSQL(int firstResultIndex,
int maxResults)
INTERNAL:
Use the JDBC maxResults and firstResultIndex setting to compute a value to use when
limiting the results of a query in SQL.
|
ValueReadQuery |
getTimestampQuery()
This method can be overridden by subclasses to return a
query that will return the timestamp from the server.
|
boolean |
isAlterSequenceObjectSupported()
INTERNAL:
Override this method if the platform supports sequence objects
and it's possible to alter sequence object's increment in the database.
|
boolean |
isDynamicSQLRequiredForFunctions()
INTERNAL
H2 has some issues with using parameters on certain functions and relations.
|
boolean |
isH2() |
static ExpressionOperator |
monthsBetweenOperator()
INTERNAL:
Use MONTH function for MONTH_BETWEEN.
|
void |
printFieldIdentityClause(java.io.Writer writer)
Append the receiver's field 'identity' constraint clause to a writer.
|
void |
printSQLSelectStatement(DatabaseCall call,
ExpressionSQLPrinter printer,
SQLSelectStatement statement)
Print the pagination SQL using H2 syntax " LIMIT <max> OFFSET <first>".
|
boolean |
supportsForeignKeyConstraints() |
boolean |
supportsGlobalTempTables()
INTERNAL:
Indicates whether the platform supports global temporary tables.
|
boolean |
supportsIdentity()
INTERNAL:
Indicates whether the platform supports identity.
|
boolean |
supportsSequenceObjects()
INTERNAL:
Indicates whether the platform supports sequence objects.
|
boolean |
supportsStoredFunctions() |
static ExpressionOperator |
toNumberOperator()
INTERNAL:
Use CONVERT function for toNumber.
|
void |
writeUpdateOriginalFromTempTableSql(java.io.Writer writer,
DatabaseTable table,
java.util.Collection pkFields,
java.util.Collection assignedFields)
H2 does not allow using () in the update if only one field.
