Very interesting! This seems odd at first, but I think I can explain it.
First, remember that a "request" to the server is simply a string of SQL in a single Request packet. As you know, it may contain multiple
statements separated by semicolons. For instance, these are multi-statement requests:
[1] "select current_date; select current_time;"
[2] "select current_date; /* comment */ select current_time;"
Each client must determine for itself how it is going to pass MSR's, if any, to Teradata. BTEQ, as you know, will not terminate the
request until it sees a semicolon not followed by anything. Well, it appears that a comment is something. If it sees a comment, it thinks it could
be like example 2, so it keeps going.
Kinda makes sense once you think about it, but it is unexpected.
