The forum will experience an outage sometime between February 10 at 7:00pm EST and February 12 at 11:59 EST for installation of security updates. The actual time and duration of the outage are unknown but attempts will be made to minimize the downtime. We apologize for any inconvenience.

SQL Anywhere version 11

**Existing table**

    "conum" "DCONUM" NOT NULL,
    "module" SMALLINT NOT NULL,
    "recseq" "DINTEGER4" NOT NULL,
    "scandate" "datetime" NOT NULL DEFAULT CURRENT TIMESTAMP,
    "scandesc" "DCHAR35" NULL,
    "image" LONG BINARY NULL,
    "fileext" CHAR(5) NULL,
    PRIMARY KEY ( "conum" ASC, "module" ASC, "recseq" ASC, "scandate" ASC )
) IN "system";
COMMENT ON COLUMN "DBA"."SYscans"."module" IS '10-SY,20-GL,etc.';


alter table syscans drop primary key;
alter table syscans add ID1 dkeytype not null default '          ';
alter table syscans add ID2 dkeytype not null default '          ';
alter table syscans add primary key(conum,module,ID1,ID2,recseq,scandate)


when running the above script using dbisqlc.exe, the second statement executes for about a minute and then the database service stops. They're 21,700 rows in the table. This problem exists in several installations so I doubt that it's environment related.

Any suggestions on troubleshooting the problem would be greatly appreciated.

Thanks, Bill

Are there other connections using the table when running the ALTER TABLE statements? If so, they may lead to (temporary) blocks. Adding columns with NON-NULL values (as here with the defaults) may lead to split rows. But all that explain that ALTER TABLE may take some time but would not explain a database stop...

What does the engine's -o console.log tell?

For logging dbisqlc's output, see here...

Which 11 are you using?

If you are using a version of 11.0.0 or an early build of 11.0.1 your crash may be due to something that was fixed by CR#738617 which was fixed in 11.0.1 builds 2979+.
