Teradata SQL multiple statements (not multistmt) in Knowledge Module Step??

Question

In a Knowledge Module Step using Teradata Technology, I have the following statements
statement 1 ;
statement 2 ;
statement 3 ;
Since the semicolons are at the end of each statement, I expect that these statements will be executed in sequential order
and not in parallel as in a multistatement. Can someone confirm this ?
I ask this question, because I observe that if statement 2 fails (say for e.g because it is an insert statement and there is no space on the database) then statement 1
is not commited either (or perhaps it is rolled back ). This behaviour is expected in multistatements (i.e. where statements run in parallel).
Thanking you all in great anticipation

Answer 1

Hi Amer,
This is obvious that in one step you have included
statement 1 ;
statement 2 ;
statement 3 ;
So any of the statement fails means this step is not going to work unless until you use AUTOCOMMIT STATMENT (drop or truncate).
If your 1st statement will be " drop table xyz"
2nd statement will be " truncate table abc""
3rd statement will be " delete from def"
if 3rd statement fails , then 1st two are auto committed and will be reflected in your database. But if 1st statement fails means its the end for this step.
If your requirement is like to do this in step of a KM better use one procedure.
Hope its helps.
Thanks
