• Batch Writing - Succeeds
• Pessimistic Locking - Succeeds with Limitations
• First Result/Limit - Succeeds with Limitations
• Expression Framework - Succeeds with Limitations
• Delimiters - Succeeds
• Auto Detection - Succeeds

Limitations
----------------

• Reserved SQL keywords cannot be used as table, column or sequence names. Use a different name, or enclose the name in double quotes. For example: @Column(name="\"LANGUAGE\"")
• Pessimistic locking adds 'FOR UPDATE' to the SELECT statement, and cannot be used with queries that use DISTINCT.
• Pessimistic locking cannot be used with queries that select from multiple tables.
• The LockNoWait option of Pessimistic Locking cannot be used; it is ignored when specified (i.e. only 'FOR UPDATE' is added to the SELECT statement).
• Bulk update and delete operations that require multiple tables to be accessed cannot be used (e.g. bulk operation on an entity that is part of an inheritance hierarchy, UpdateAll and DeleteAll queries). <li>'= NULL' and '<> NULL' cannot be used for null comparisons in the WHERE clause. Use 'IS (NOT) NULL' instead.
• Scrollable cursors are not supported.
• Query timeouts are not supported.

Method Detail

isHANA

public boolean isHANA()

Specified by:

isHANA in interface Platform

Overrides:

isHANA in class DatasourcePlatform

usesStringBinding

public boolean usesStringBinding()

Overrides:

usesStringBinding in class DatabasePlatform

requiresUniqueConstraintCreationOnTableCreate

public boolean requiresUniqueConstraintCreationOnTableCreate()

Description copied from class: DatabasePlatform

Used for table creation. If a database platform does not support ALTER TABLE syntax to add/drop unique constraints (like Symfoware), overriding this method will allow the constraint to be specified in the CREATE TABLE statement.

This only affects unique constraints specified using the UniqueConstraint annotation or equivalent method. Columns for which the 'unique' attribute is set to true will be declared 'UNIQUE' in the CREATE TABLE statement regardless of the return value of this method.

Overrides:

requiresUniqueConstraintCreationOnTableCreate in class DatabasePlatform

Returns:

whether unique constraints should be declared as part of the CREATE TABLE statement instead of in separate ALTER TABLE ADD/DROP statements.

isForUpdateCompatibleWithDistinct

public boolean isForUpdateCompatibleWithDistinct()

Description copied from class: DatabasePlatform

INTERNAL: Indicates whether SELECT DISTINCT ... FOR UPDATE is allowed by the platform (Oracle doesn't allow this).

Overrides:

isForUpdateCompatibleWithDistinct in class DatabasePlatform

supportsIndividualTableLocking

public boolean supportsIndividualTableLocking()

Description copied from class: DatabasePlatform

INTERNAL: Indicates whether locking clause could be selectively applied only to some tables in a ReadQuery. Example: the following locks the rows in SALARY table, doesn't lock the rows in EMPLOYEE table: on Oracle platform (method returns true): SELECT t0.EMP_ID..., t1.SALARY FROM EMPLOYEE t0, SALARY t1 WHERE ... FOR UPDATE t1.SALARY on SQLServer platform (method returns true): SELECT t0.EMP_ID..., t1.SALARY FROM EMPLOYEE t0, SALARY t1 WITH (UPDLOCK) WHERE ...

Overrides:

supportsIndividualTableLocking in class DatabasePlatform

createLocateOperator

public static ExpressionOperator createLocateOperator()

INTERNAL: Build locate operator i.e. LOCATE("ob", t0.F_NAME)

createLocate2Operator

public static ExpressionOperator createLocate2Operator()

INTERNAL: Build locate operator with 3 params i.e. LOCATE("coffee", t0.DESCRIP, 4). Last parameter is a start at.

printSQLSelectStatement

public void printSQLSelectStatement(DatabaseCall call,
                                    ExpressionSQLPrinter printer,
                                    SQLSelectStatement statement)

Description copied from class: DatabasePlatform

INTERNAL: Print the SQL representation of the statement on a stream, storing the fields in the DatabaseCall.

Overrides:

printSQLSelectStatement in class DatabasePlatform

computeMaxRowsForSQL

public int computeMaxRowsForSQL(int firstResultIndex,
                                int maxResults)

Description copied from class: DatabasePlatform

INTERNAL: Use the JDBC maxResults and firstResultIndex setting to compute a value to use when limiting the results of a query in SQL. These limits tend to be used in two ways. 1. MaxRows is the index of the last row to be returned (like JDBC maxResults) 2. MaxRows is the number of rows to be returned By default, we assume case 1 and simply return the value of maxResults. Subclasses may provide an override

Overrides:

computeMaxRowsForSQL in class DatabasePlatform

See Also:

MySQLPlatform

shouldOptimizeDataConversion

public boolean shouldOptimizeDataConversion()

Description copied from class: DatabasePlatform

Return if our driver level data conversion optimization is enabled. This can be disabled as some drivers perform data conversion themselves incorrectly.

Overrides:

shouldOptimizeDataConversion in class DatabasePlatform

supportsNativeSequenceNumbers

public final boolean supportsNativeSequenceNumbers()

Overrides:

supportsNativeSequenceNumbers in class DatasourcePlatform

buildSelectQueryForSequenceObject

public final ValueReadQuery buildSelectQueryForSequenceObject(java.lang.String sequenceName,
                                                              java.lang.Integer size)

Description copied from class: DatasourcePlatform

INTERNAL: Returns query used to read value generated by sequence object (like Oracle sequence). In case the other version of this method (taking no parameters) returns null, this method is called every time sequence object NativeSequence reads. If the platform supportsSequenceObjects then (at least) one of buildSelectQueryForSequenceObject methods should return non-null query.

Overrides:

buildSelectQueryForSequenceObject in class DatasourcePlatform

supportsGlobalTempTables

public final boolean supportsGlobalTempTables()

Description copied from class: DatabasePlatform

INTERNAL: Indicates whether the platform supports global temporary tables. "Global" means that an attempt to create temporary table with the same name for the second time results in exception. EclipseLink attempts to create global temporary table in the beginning of UpdateAllQuery, execution and assumes that it already exists in case SQLException results. In the end of UpdateAllQuery execution all rows are removed from the temporary table - it is necessary in case the same temporary table will be used by another UpdateAllQuery in the same transaction. Override this method if the platform supports global temporary tables. Note that this method is ignored in case supportsLocalTempTables() returns true.

Overrides:

supportsGlobalTempTables in class DatabasePlatform

getTempTableForTable

public DatabaseTable getTempTableForTable(DatabaseTable table)

Description copied from class: DatabasePlatform

INTERNAL: May override this method if the platform support temporary tables.

Overrides:

getTempTableForTable in class DatabasePlatform

Returns:

DatabaseTable temorary table

getMaxFieldNameSize

public final int getMaxFieldNameSize()

Description copied from class: DatabasePlatform

INTERNAL: returns the maximum number of characters that can be used in a field name on this platform.

Overrides:

getMaxFieldNameSize in class DatabasePlatform

supportsLocalTempTables

public final boolean supportsLocalTempTables()

Description copied from class: DatabasePlatform

INTERNAL: Indicates whether the platform supports local temporary tables. "Local" means that several threads may create temporary tables with the same name. Local temporary table is created in the beginning of UpdateAllQuery execution and dropped in the end of it. Override this method if the platform supports local temporary tables.

Overrides:

supportsLocalTempTables in class DatabasePlatform

shouldAlwaysUseTempStorageForModifyAll

public final boolean shouldAlwaysUseTempStorageForModifyAll()

Description copied from class: DatabasePlatform

INTERNAL: That method affects UpdateAllQuery and DeleteAllQuery execution. In case it returns false modify all queries would attempt to proceed without using temporary storage if it is possible. In case it returns true modify all queries would use temporary storage unless each modify statement doesn't reference any other tables. May need to override this method if the platform can't handle the sql generated for modify all queries without using temporary storage.

Overrides:

shouldAlwaysUseTempStorageForModifyAll in class DatabasePlatform

shouldBindLiterals

public final boolean shouldBindLiterals()

Description copied from class: DatabasePlatform

PUBLIC: Allows platform to choose whether to bind literals in DatabaseCalls or not.

Overrides:

shouldBindLiterals in class DatabasePlatform

shouldPrintOuterJoinInWhereClause

Overrides:

shouldPrintOuterJoinInWhereClause in class DatabasePlatform

shouldUseJDBCOuterJoinSyntax

public final boolean shouldUseJDBCOuterJoinSyntax()

Description copied from class: DatabasePlatform

JDBC defines and outer join syntax, many drivers do not support this. So we normally avoid it.

Overrides:

                        boolean isStatementPrepared)
                 throws java.sql.SQLException

Description copied from class: DatabasePlatform

Internal: This gets called on each batch statement execution Needs to be implemented so that it returns the number of rows successfully modified by this statement for optimistic locking purposes.

Overrides:

executeBatch in class DatabasePlatform

isStatementPrepared - - flag is set to true if this statement is prepared

Returns:
