Subj:   2620 in Stored Procedure using Dynamic SQL
 
From:   Anomy Anom

<-- Anonymously Posted: Wed, 11 Mar 2009 17:10 -->

Hi,

We have the Store Procedure (below) which errors with a 2620 in the highlighted area.

The data row it is trying to input into Systec.MVCanalysis is :-

     Exec Date Time = current_Timestamp(0)
     Databasename   = 'Sys_Reporting'
     Tablename      = 'qqq_logtable'
     Columnname     = 'accountname'
     xVal           =  $L$NOD   DBA  PERF   &D&H0&S
     xCnt           =  2
     xRnk           =  4

DDL for Systec.MVCAnalysis

     CREATE MULTISET TABLE systec.mvcanalysis ,NO FALLBACK ,
         NO BEFORE JOURNAL,
         NO AFTER JOURNAL,
         CHECKSUM = DEFAULT
         (
           ExecDateTime TIMESTAMP(0) DEFAULT CURRENT_TIMESTAMP(0),
           DatabaseName VARCHAR(128) CHARACTER SET LATIN NOT CASESPECIFIC NOT NULL,
           TableName VARCHAR(128) CHARACTER SET LATIN NOT CASESPECIFIC NOT NULL,
           ColumnName VARCHAR(128) CHARACTER SET LATIN NOT CASESPECIFIC NOT NULL,
           xVal VARCHAR(5000) CHARACTER SET LATIN NOT CASESPECIFIC,
           xCnt FLOAT NOT NULL,
           xRnk INTEGER NOT NULL)
        UNIQUE PRIMARY INDEX ( ExecDateTime ,DatabaseName ,TableName ,
           ColumnName ,xVal ,xCnt ,xRnk );

I know the problem is with the data value for xVal and the fact it contains a 2nd '$' sign, but I don't know why it is erroring and how to fix it.

The SQL that is generated works fine as a separate BTEQ - ie it inserts the row. So it must be something to do with the way the Store Procedure handles the data value .

Any help would be appreciated.



Stored Procedure:
