Build Identifier:

When calling a update statement inside a SQL procedure, the server receives a SIGABRT on exp_bin function call while compiling the procedure.

Reproducible: Always

Steps to Reproduce:

  1. create table stmp10 (t timestamp, sensor integer, val decimal(8,2)) ;
  2. create table tmp_aggregate(tmp_total decimal(8,2), tmp_count decimal(8,2));
  3. insert into tmp_aggregate values(0.0,0.0);
  4. create procedure cq_collector()
    begin
    update tmp_aggregate
    set tmp_total = tmp_total + (select sum(val) from sys.stmp10),
    tmp_count = tmp_count + (select count(*) from sys.stmp10);
    end;
  5. call cq_collector();

Actual Results:

Servers receives a SIGABRT on the exp_bin function call.

Expected Results:

The table tmp_aggregate continues unchanged.

The assertion error:

mserver5: rel_bin.c:575: exp_bin: Assertion `s' failed.
