Subject [jira] Created: (DERBY-2202) DROP PROCEDURE depends on SET SCHEMA
Date Thu, 28 Dec 2006 13:52:21 GMT
DROP PROCEDURE depends on SET SCHEMA
------------------------------------

                 Key: DERBY-2202
                 URL: http://issues.apache.org/jira/browse/DERBY-2202
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.2.2.0
         Environment: Sun Solaris;
java version "1.4.1_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_06-b01)
Java HotSpot(TM) Client VM (build 1.4.1_06-b01, mixed mode)
            Reporter: Bernhard Bodenstorfer
            Priority: Minor


This is possibly related to Bug https://issues.apache.org/jira/browse/DERBY-1304.

Use ij to execute the following statements:

CREATE SCHEMA datamgmt;
CREATE PROCEDURE datamgmt.exit ( IN value INTEGER )
 MODIFIES SQL DATA
 PARAMETER STYLE JAVA
 LANGUAGE JAVA
 EXTERNAL NAME 'java.lang.System.exit'
;
DROP PROCEDURE datamgmt.exit;
DROP SCHEMA datamgmt RESTRICT;

Then execute exactly the same lines once again. Then statement "DROP PROCEDURE datamgmt.exit"
yields:

ERROR 42X94: PROCEDURE 'EXIT' does not exist.

However, if the DROP works if a default schema (SET SCHEMA) is used instead of the prefixed
schemaName. That is, the following lines can be executed more than once in a row:

CREATE SCHEMA datamgmt;
CREATE PROCEDURE datamgmt.exit ( IN value INTEGER )
 MODIFIES SQL DATA
 PARAMETER STYLE JAVA
 LANGUAGE JAVA
 EXTERNAL NAME 'java.lang.System.exit'
;
SET SCHEMA datamgmt;
DROP PROCEDURE exit;
DROP SCHEMA datamgmt RESTRICT;

Therefore, SET SCHEMA can be used as a workaround, hence minor importance.
