CLOSE Statement—End Cursor Operation

Issue a CLOSE statement to end a cursor operation.

Keep this information in mind when using the CLOSE statement:

The SQL command that executes the CLOSE statement must be issued from an AOF rule, an OPS/REXX program, a TSO/E REXX program, or a TSO CLIST. You cannot invoke SQL commands that perform cursor operations from a TSO terminal.
It is important to include the CLOSE statement when a cursor operation has ended to release resources.

Use this syntax in an AOF rule or an OPS/REXX program:

ADDRESS SQL "CLOSE keywords" {cursorname}
[SYSTEM(ALL|EXT|sysnames)]
[SYSWAIT(seconds)]
[OUTPUT|NOOUTPUT]
[SYSPLEX]

Use this syntax to invoke the statement from a TSO/E REXX program or a TSO CLIST:

OPSQL CLOSE {cursorname}

You may specify these operands for the CLOSE statement:

cursorname

Defines the name of the cursor operation you are ending.

SYSTEM

Performs cross-system SQL operations. Specify one of these values:

ALL

Routes the SQL command to all active MSF-defined systems, including the local system.

EXT

Routes the SQL command to all remote, active MSF-defined systems.

sysnames

Routes the SQL command to the specified systems. You may specify from one to eight system names as the value of sysnames.

For more information, see the chapter “Using the Relational Data Framework” in the User Guide.

SYSWAIT

Defines the number of seconds the SQL processor waits for output from a remote system. You may specify a value between 1 and 300 seconds.

Do not specify a value for SYSWAIT if you specify the SYSTEM(ALL), SYSTEM(EXT), or NOOUTPUT keywords.

OUTPUT or NOOUTPUT

Indicates whether the command returns output to the external data queue. Specify OUTPUT to have output returned; otherwise, specify NOOUTPUT.

NOOUTPUT is implied when:

The ADDRESS SQL command is issued in an AOF rule.
You specify more than one system name as the value of the SYSTEM(sysnames) keyword.
You specify SYSTEM(ALL) or SYSTEM(EXT).

SYSPLEX: (Optional) Reduces the scope of the SYSTEM(ALL|EXT) operand to MSF connected systems that belong to the same z/OS sysplex as the command issuer. The keyword has no effect on a list of explicit system names.

Example: CLOSE CURSTAT Command

To end the cursor operation named CURSTAT, you can issue this command from an OPS/REXX program:

ADDRESS SQL
  "CLOSE CURSTAT"
