EXIT statement [Interactive SQL]

Description

Use this statement to leave Interactive SQL.

Syntax

{ EXIT | QUIT | BYE } [ return-code ]

return-code: number | connection-variable

This statement closes your connection with the database, then closes the Interactive SQL environment. Before closing the database connection, Interactive SQL automatically executes a COMMIT statement if the COMMIT_ON_EXIT option is set to ON. If this option is set to OFF, Interactive SQL performs an implicit ROLLBACK. By default, the COMMIT_ON_EXIT option is set to ON.

The optional return code can be used in batch files to indicate success or failure of the commands in an Interactive SQL command file. The default return code is 0.

Permissions

None.

Side effects

This statement automatically performs a commit if option COMMIT_ON_EXIT is set to ON (the default); otherwise it performs an implicit rollback.

On Windows operating systems the optional return value is available as ERRORLEVEL.

Standards and compatibility

SQL/92 Vendor extension.
SQL/99 Vendor extension.
Sybase Not applicable in Adaptive Server Enterprise.

Examples

The following example sets the Interactive SQL return value to 1 if there are any rows in table T, or to 0 if T contains no rows.

CREATE VARIABLE rowCount INT;
CREATE VARIABLE retcode INT;
SELECT COUNT(*) INTO rowCount FROM T;
IF( rowCount > 0 ) THEN
    SET retcode = 1;
ELSE
    SET retcode = 0;
END IF;
EXIT retcode;

The following Windows batch file prints Error = 1 on the command prompt.

dbisql -c "dsn=ASA 9.0 Sample" EXIT 1
if errorlevel 1 echo "Errorlevel is 1"
