Question

Dynamic Variables in FROM clauses in SQR

Asked by: AGenMIS

We are in the process of upgrading our PeopleSoft database platform from SQL Server 2000 to 2005.  During our testing we ran into a problem with 2005 in that it requires the use of ANSI Standard Outer Joins but some of our custom SQRs use Non-ANSI standard joins.  

When we made the necessary ANSI Standard changes to the programs we ran into errors from putting dynamic variables into the FROM clause of a Select statement.  We want to avoid changing the compatibility level back to 8.0 so we need to get all of the queries using ANSI Standard Outer Joins.  I'm getting the following errors when running the modified SQRs:

(SQR 1303) Error in SQL (perhaps missing &name after expression):
(SQR 1304) Check SELECT columns, expressions and 'where' clause for syntax.

The code that is referenced below is all in a Begin-Select statement and when the query is run in MS Query Analyzer it runs successfully.

Try the following (untested).

SELECT *
FROM PS_PAY_TAX TBAL
LEFT OUTER JOIN
( SELECT STATE, LOCALITY, TAX_GRP_TYPE, MAX(EFFDT) EFFDT
 FROM PS_LOCL_TX_TYP_TBL
 WHERE EFFDT <= #AGLCLTAX_THRU_DT
 GROUP BY STATE, LOCALITY, TAX_GRP_TYPE
) LTTT1
ON TBAL.STATE = LTTT1.STATE
AND TBAL.LOCALITY = LTTT1.LOCALITY
LEFT OUTER JOIN  PS_LOCL_TX_TYP_TBL LTTT2
ON LTTT1.STATE = LTTT2.STATE
AND LOCALITY = LTTT.LOCALITY
AND TAX_GRP_TYPE = LTTT.TAX_GRP_TYPE
AND LTT1.EFFDT = LTT2.EFFDT ;

you can not use special characters (such as $)  in this query

  $AGLCLTAX_THRU_DT


for variables in sql server you need
to declare variable first then

use as
@AGLCLTAX_THRU_DT

http://msdn.microsoft.com/en-us/library/ms188927.aspx

declare @AGLCLTAX_THRU_DT Datetime
 
Select ....
 
FROM PS_PAY_TAX TBAL LEFT OUTER JOIN PS_LOCL_TX_TYP_TBL LTTT
 ON (TBAL.STATE        = LTTT.STATE
         AND TBAL.LOCALITY = LTTT.LOCALITY
        AND LTTT.EFFDT    = (SELECT MAX(EFFDT)
                                              FROM PS_LOCL_TX_TYP_TBL 
                                              WHERE STATE      = LTTT.STATE
                                              AND LOCALITY     = LTTT.LOCALITY
                                              AND TAX_GRP_TYPE = LTTT.TAX_GRP_TYPE
                                              AND EFFDT        <= @AGLCLTAX_THRU_DT))

I was able to solve this problem by stringing together the entire FROM clause and then using the FROM clause substitution to dynamically populate the variable.

let $ANSI_From_Stmt =  'PS_PAY_TAX TBAL LEFT OUTER JOIN PS_LOCL_TX_TYP_TBL LTTT                                                   
		        ON (TBAL.STATE = LTTT.STATE                                                       
			AND TBAL.LOCALITY = LTTT.LOCALITY                                             
			AND LTTT.EFFDT = (SELECT MAX(EFFDT)                                           
			                  FROM PS_LOCL_TX_TYP_TBL                                     
			                  WHERE STATE = LTTT.STATE                                    
			                  AND LOCALITY = LTTT.LOCALITY                                
			                  AND TAX_GRP_TYPE = LTTT.TAX_GRP_TYPE                        
			                  AND EFFDT <=' || '''' || $AGLCLTAX_THRU_DT || '''' || ')),  
			PS_PAY_CHECK TBAL1, 
			PS_LOCAL_TAX_TBL2 LTBL, 
		        PS_ADDRESSES PERS' 
 
FROM [PS_PAY_TAX TBAL, PS_LOCL_TX_TYP_TBL LTTT, PS_PAY_CHECK TBAL1, PS_LOCAL_TAX_TBL2 LTBL, PS_ADDRESSES PERS:$ANSI_From_Stmt]

hmm. it is not sql server query

 

by: AGenMISPosted on 2009-07-01 at 08:13:04ID: 24755184

It is a sql server query but it's being compiled and executed within a SQR program.  Therefore you can't use sql server variable declarations or any other transact-sql statements in conjunction with the select statement.
