My requirement is to execute the below sql query
Code:
SQLSTMT= "SELECT NAME FROM SYSIBM.SYSCOLUMNS",       
"WHERE TBCREATOR='CI1'",                                     
"AND NAME IN (SELECT NAME FROM SYSIBM.SYSCOLUMNS" ,           
"WHERE TBCREATOR='CI1' AND TBNAME=TABNAME1 AND KEYSEQ > 0 )" 

I want to pass the TABNAME1 value dynamically. How to acheive this in Rexx.

if You are using the REXX sql interface the sql query is just a REXX string
and can be built by concatenating the needed fragments

Code:

get the query variables ... for example with
parse arg creator tablnam
.......
SQLSTMT= "SELECT NAME FROM SYSIBM.SYSCOLUMNS" || ,
         "WHERE TBCREATOR='" || creator || "'" || ,                                      
         "AND NAME IN (SELECT NAME FROM SYSIBM.SYSCOLUMNS" || ,
                       "WHERE TBCREATOR='" || creator || "'" || ,                                      
                       "AND TBNAME='" || tablnam || "'" || ,
                       "AND KEYSEQ > 0 )" 


the above snippet only shows how to build the query string from Your sample
is not concerned about sql goodness icon_biggrin.gif
