db2set DB2_OPTPROFILE=YES
create table t1(c1 int,c2 int,c3 int);
create index i1 on t1(c1);
"Query: select * from t1 where c1+1>1;
Optimizer profile content:
<OPTGUIDELINES>
<IXSCAN TABLE='T//1' INDEX='I1'/>
</OPTGUIDELINES>;
Compiling the query returns the following message:
SQL0901N The SQL statement failed because of a non-severe
system error.
Subsequent SQL statements can be processed. SQLSTATE=58004
With the APAR fix, the query compilation will be complete and an
explain diagnostic message
EXP0009W will be logged in explain table. |
