Db2 Sql Error Code 805
reference manuals are not available or close at hand when you really need them. This reference will review SQL return code processing and common SQL error condition codes you may encounter in DB2. SQL Error Code Lookup Retrieving SQL Return Code Information & Messages COBOL programs executing SQL statements communicate with DB2 via a Working Storage area called the SQL Communications Area (SQLCA). When DB2 executes SQL statements, it returns the results of the operation db2 sql error code 404 into the SQLCODE and SQLSTATE fields in the SQLCA. SQLCODE provides key information about the success or failure of SQL statement execution. If the SQLWARNO field in the SQLCA contains 'W', DB2 has set at least one of the SQL warning flags (SQLWARN1 through SQLWARNA). These flags provide additional info about execution of specific types of SQL. Prior to DB2 V8, COBOL programs could call a subroutine called DSNTIAR that would convert a SQLCODE in the SQLCA into more a detailed text message with diagnostics about the return code. New with DB2 V8, COBOL programs can now execute a GET DIAGNOSTICS statement that will return all previous SQLCA values and provide additional information about new DB2 V8 extended object names and new SQL functions. The new GET DIAGNOSTICS function replaces existing SQLCA processing now found in most DB2 COBOL programs. GET DIAGNOSTICS also passes a text message about SQLCODE directly to programs. SQLCODE Overview If SQLCODE = 0, execution was successful. If SQLCODE > 0, execution was successful with a warning. If SQLCODE < 0, execution was not successful. If SQLCODE = 100, "no data" was found. For example, a FETCH statement returned no data because the cursor was positioned after the last row of the result table. New with DB2 V8, when DB2 processes a multiple row FETCH statement, the contents of SQLCO

But it db2 sql is not working in DB2. It is throwing DB2 SQL Error: SQLCODE=-811, SQLSTATE=21000, SQLERRMC=null, DRIVER=3.61.65 error when the sub query under THEN clause is returning 2 rows. However, my question is why would it execute in the first place as my WHEN clause turns to be false always.

Oracle chooses to specify shortcut evaluation, however DB2 seems to not do that. Rewriting your query a little for DB2 (8.1+ only for FETCH in subqueries) should allow it to run (unsure if you need the added ORDER BY and don't have DB2 to test on at the moment) SELECT CASE WHEN (SELECT COUNT(1) FROM STOP ST, FACILITY FAC WHERE ST.FACILITY_ID = FAC.FACILITY_ID AND FAC.IS_DOCK_SCHED_FAC=1 AND ST.SHIPMENT_ID = 2779) = 1 THEN (SELECT ST.FACILITY_ALIAS_ID FROM STOP ST, FACILITY FAC WHERE ST.FACILITY_ID = FAC.FACILITY_ID AND FAC.IS_DOCK_SCHED_FAC=1 AND ST.SHIPMENT_ID = 2779 ORDER BY ST.SHIPMENT_ID FETCH FIRST 1 ROWS ONLY ) ELSE NULL END STAPPFAC FROM SHIPMENT SHIPMENT WHERE SHIPMENT.SHIPMENT_ID IN (2779); share|improve this answer answered Sep 27 '14 at 9:05 Joachim Isaksson 116k11134170 Syntactically, the ORDER BY isn't ever

To resolve this you can use the concept of cursor in DB2. Was this answer useful?Yes 1 Reply chandu Jul 14th, 2011 THE RESULT OF AN EMBEDDED SELECT STATEMENT IS A TABLE OF MORE THAN ONE ROW, OR THE RESULT OF THE SUBQUERY OF A BASIC PREDICATE IS MORE THAN ONE VALUE.Explanation :: Execution of an embedded SELECT statement has resulted in a result table containing more than one row. Alternatively, a sub query contained in a basic predicate has produced more than one value. Was this answer useful?Yes 1 Reply BrantleyL1 ProfileAnswers by BrantleyL1 Jul 27th, 2011 Yes, this is returned when you do a select and the result is more than one row...But what to do?? If your table needs to allow for more than one row with the select values in use, you WILL need to use a cursor.Otherwise, if it does not, you will need to add code (probably in another program) to prevent the duplicates. And remove the duplicates from the table.
