RE: MAL script error

Hi Martin,

After applying this fix, MAL plans are still not working, but now giving errors on other functions like projectdelta, delta etc

TPCH q02 !TypeException:user.s1_1[6]:'sql.projectdelta' undefined in: X_18:any := sql.projectdelta(X_7:bat[:oid,:oid], X_10:bat[:oid,:oid], X_13:bat[:oid,:oid], r1_13:bat[:oid,:any], X_16:bat[:oid,:oid]) !TypeException:user.main[1]:'user.s1_1' undefined in: _1:any := user.s1_1()

TPCH q13 !TypeException:user.s1_1[8]:'sql.delta' undefined in: X_20:any := sql.delta(X_12:bat[:oid,:oid], X_15:bat[:oid,:oid], r1_15:bat[:oid,:any], X_18:bat[:oid,:oid]) !TypeException:user.main[1]:'user.s1_1' undefined in: _1:any := user.s1_1()

Regards,

Hi

I see, in sql_gencode.c the same patch should be applied on line 921:

case st_idxbat:{ ... if (s->flag == RD_UPD_ID) { q = pushReturn(mb, q, newTmpVariable(mb, newBatType(ht, tt))); } else{ setVarType(mb, getArg(q, 0), newBatType(ht, tt)); setVarUDFtype(mb, getArg(q, 0)); }

Hi Martin,

Thanks for the fix. However, TPCH MAL plans still show the same errors:

Installed: changeset 53316:192a529eaa4a http://dev.monetdb.org/hg/MonetDB/rev/192a529eaa4a

Running MAL plan: sql/benchmarks/tpch/Tests/02-explain.stable.out

I get the following exception: !TypeException:user.s2_1[25]:'algebra.join' undefined in: (X_41:any, r1_46:any) := algebra.join(X_31:bat[:oid,:oid], X_40:bat[:oid,:any]) !TypeException:user.main[1]:'user.s2_1' undefined in: _1:any := user.s2_1()

Even if I regenerate the query plan myself, I get same exception.

Thanks for the help.

Hi Martin,

I had the same issue. Could you give a clue how to fix the problem in other MAL plans? Thanks!

Hi

I found the culprit. The types of some of the sql.bind() calls are not retained in the listing, which should have been.

 X_10 := sql.bind(X_6,"sys","nation","n_regionkey",0);
  X_16 := sql.bind(X_6,"sys","region","r_name",0);
  X_21 := sql.bind(X_6,"sys","region","r_regionkey",0);
  X_29 := sql.bind(X_6,"sys","nation","n_nationkey",0);
  X_35 := sql.bind(X_6,"sys","supplier","s_nationkey",0);
  X_41 := sql.bind(X_6,"sys","supplier","s_suppkey",0);
  X_49 := sql.bind(X_6,"sys","partsupp","ps_suppkey",0);
  X_54 := sql.bind(X_6,"sys","partsupp","ps_partkey",0);

A bug report has been filed.

Hi Marten,

I didn't modify the query plan. I retrieved the query plan using 'explain <sql query>' for tpch query #02. However, I checked the latest MonetDB version 11.17.21, it also gives the errors.

Further, upon running the MAL function for TPCH query #02 located in: MonetDB-11.17.21/sql/benchmarks/tpch/Tests/02-explain.stable.out

I also get:

!TypeException:user.s2_1[23]:'algebra.join' undefined in: (X_41:any, r1_46:any) := algebra.join(X_31:bat[:oid,:oid], X_40:bat[:oid,:any])

!TypeException:user.main[1]:'user.s2_1' undefined in: _1:any := user.s2_1()

this is insufficient to identify. Most likely you attempted to use a modified plan, where the type of z-150 and r1-280 can not be statically determined.

 The equivalent SQL query works fine but I am interested in running MAL script via mserver5. How can I resolve the above exceptions please?

 Thanks.
