I want to drop a column called id which is an auto incrementing PK.

I want to drop a column called id which is an auto incrementing PK.

The SQL: 

alter table "CO88GT"."XGLCTL" drop column id cascade;

And I get:

Error: [SQL0952] Processing of the SQL statement ended.  Reason code 10.

SQLState:  57014

ErrorCode: -952

I could be wrong but I think it has something to do with preventing the table from losing data. To get around this issue I need to create a new table without the column and copy the data from the old table into the new table and then replace the old table with the new table.

    Info

    AS400 is giving you a warning (inquiry message) because of possible data loss, asking you to Cancel or Ignore the requested operation. So, beacuse of this being a interactive request, over JDBC/ODBC you cannot type ‘I’ to ignore, and AS throws you an ErrorCode: -952 with SQLState: 57014 and Reason code 10.

    In the documentation of SQL0952 says:

    Message Text:   Processing of the SQL statement ended. Reason code &1.
Cause Text:     The SQL operation was ended before normal completion. The reason code is &1. Reason codes and their meanings are:

* 1 - An SQLCancel API request has been processed, for example from ODBC.
* 2 - SQL processing was ended by sending an exception.
* 3 - Abnormal termination.
* 4 - Activation group termination.
* 5 - Reclaim activation group or reclaim resources.
* 6 - Process termination.
* 7 - An EXIT function was called.
* 8 - Unhandled exception.
* 9 - A Long Jump was processed.
* 10 - A cancel reply to an inquiry message was received.
* 11 - Open Database File Exit Program (QIBM_QDB_OPEN).
* 0 - Unknown cause.

    If you are using JDBC and the SQL error isn’t self-explanatory, you can make a JDBC connection with parameter ‘errors=full‘, which will give much more info on the error. For other connection parameters see this.

    example connection string:

    jdbc:as400://serverName;libraries=*libl;naming=system;errors=full;

    With that connection the resulting error would be like this:

    Error: [SQL0952] Processing of the SQL statement ended.  Reason code 10.
Cause . . . . . :   The SQL operation was ended before normal completion.
The reason code is 10.
Reason codes and their meanings are:
1 -- An SQLCancel API request has been processed, for example from ODBC.
2 -- SQL processing was ended by sending an exception.
3 -- Abnormal termination.
4 -- Activation group termination.
5 -- Reclaim activation group or reclaim resources.
6 -- Process termination.
7 -- An EXIT function was called.
8 -- Unhandled exception.
9 -- A Long Jump was processed.
10 -- A cancel reply to an inquiry message was received.
11 -- Open Database File Exit Program (QIBM_QDB_OPEN).
0 -- Unknown cause.
Recovery  . . . :   If the reason code is 1, a client request was made to cancel SQL processing.  For all other reason codes, see previous messages to determine why SQL processing was ended.

SQLState:  57014
ErrorCode: -952

    The solution

    So finally, if you cannot use STRSQL, another solution is to use iSeries Navigator, to be exact its “Run SQL scripts” (it is usually here –> “%Program Files%\IBM\Client Access\Shared\cwbundbs.exe”).

    But first of all you have to add a system reply parameter (only once per machine)

    ADDRPYLE SEQNBR(1500) MSGID(CPA32B2) RPY(‘I’)

    This is done in “green screen”. This sets a deafult answer (‘I’) on CPA32B2 inquiry message. The CPA32B2 is an internal massage id, which is tied to an drop column operation.

    (It actually doesn’t have to be done in “green screen”, use it like CHGJOB command. Example :

    cl: ADDRPYLE SEQNBR(1500) MSGID(CPA32B2) RPY(‘I’);

    )

    Now you can start “Run SQL scripts”, the first command to run is:

    cl: CHGJOB INQMSGRPY(*SYSRPYL);

    this changes the current job parameter INQMSGRPY, to *SYSRPYL. *SYSRPYL causes to look if exists a system reply parameter when an inquiry message should be displayed.

    Now you can run your alter which drops the column.

    Unfortunately, I don’t know how to drop a column, just using JDBC. If someone knows please let me know.
