Thank you both for reply.
First thing is that No dates has zero as Patric have stated and I can display them well in ABAP. It is the issue in Studio and hbsql at LINUX level.
I tried the
select bname,bcode,to_date(gltgv,'YYYYMMDD') from "SAPQ12"."USR02";
I get the same syntax error. It is funny that not all date field has an issue.
Could not execute 'select bname,bcode,to_date(gltgv,'YYYY-MM-DD') from "SAPQ12"."USR02"' in 743 ms 752 µs . [303]: invalid DATE, TIME or TIMESTAMP value: Error while parsing DATE/TIME at function to_date()
Try this SQL in Studio -
select bname,bcode,erdat,gltgv from "SAPQ12"."USR02";
The GLTGV will be displayed 00000000 and erdat will be displayed normally.
I checked ABAP DATA elelement and they are both same.
I really do not know where is the issue.
Please let me know if anybody has any idea about it.
Best Regards,
SS
