Hi ,

I am using the XML Message Set.
Input data for my compute node is the Databasae table and the output message set is XML.

ESQL from my compute node is below:

SET "OutputRoot"."XML"."NAME" = (SELECT ITEM T.IDENTIFIER Database.MRM_USER AS T WHERE T.USER_KEY = 1 );


My select statement will return only a single row data.Still i am getting the
following error.


BIP2524E: (12, 1) : Cannot assign a list to a non-list, nor a non-list to a list.

A list of values cannot be assigned to a scalar variable or single message field, nor can a scalar value be assigned to a list.
Correct the syntax of the expression and redeploy the message flow.


Can anyne tell me how to dealt this problem.

If you are sure it only returns one row, the THE keyword should work for you.

SET "OutputRoot"."XML"."NAME" = THE (SELECT ITEM T.IDENTIFIER Database.MRM_USER AS T WHERE T.USER_KEY = 1 );
