Only an ET or null statement is legal after a DDL Statement - response (1) by ulrich

As you wanne use the query band setting only for the one sql try
BT;
 
SET QUERY_BAND = 'Project=Example2;Report=0315-17.11;MSTRUser=MSTRPORTAL_EXXXX;' FOR transaction;
select * from table1;
ET;
 
at least it worked for me in V2R14
