In my message flow i am using database insert statement as follow..

SELECT COUNT(*) FROM Database.DBDNS.DBSCHEMA.EMPLOYEE AS X WHERE(X.A= X.B);
when I use the above statement every thing is is working fine. Iam trying to get te DBDNS and DBSCHEMA from property file to retrive dynamically. But getting error to connect database.. Pl find the below ESQL statements which is not working correctly.

Declare dbDNS_values char;
declare DBSchema_value char;
SET dbDNS_values =get this values from prop file(DBDNS)
SET DBSchema_value= get this values from prop file(DBSCHEMA)

SELECT COUNT(*) FROM Database.{dbDNS_values}.{DBSchema_value}.EMPLOYEE AS X WHERE(X.A= X.B);

But getting database exception as below..
[IBM][CLI Driver][DB2/SUN64] SQL0204N "DBDNS.DBSCHEMA.EPC" is an undefined name. SQLSTATE=42704
please let me know how to use the ESQL statement to get the values dynamcially and which will be the same as the first sql statement

How are you reading a property file in ESQL ?

Regards.

What is EPC here ?

Is is table name ?

I can not see it in your select ?

Is it part of DBSchema_value ( red from property file ) ?

Check it.

Hi All,

the below code is working fine.. with the values..

SELECT COUNT(*) FROM Database.{dbDNS_values}.{DBSchema_value}.EMPLOYEE AS X WHERE(X.A= X.B);

Where dbDNS_values & DBSchema_value are getting from Property files using and Java and storing those values as SHARED Variables..
