Legend:

Y: Can be used in SQLJ.

N (SQLJ): Cannot be used in SQLJ, but a similar function is available in the functions provided by SQLJ or JAVA.

N (JDBC): Cannot be used in SQLJ, but a similar function is available when JDBC is used.

N: Cannot be used in SQLJ.

None: There is no alternate means.

Note

SQLJ cannot use HiRDB functions that are not provided by the JDBC driver. The following functions cannot be used:

• UPDATE statement and DELETE statement that use an iterator
• Specification of a keyword in a WITH clause during the declaration of an iterator
• INSERT function that uses an array

^* If you use a JDBC connection object to create a connection context, you can also use the alternate means with the native interface. If you do not use a JDBC connection object to create a connection context, you cannot use the alternate means.
