Re: Error message Text for SQL

SQL - sometimes quirky lingo

Well it was good while it lasted.

The MESSAGE_TEXT appears to only include the level 1 text. The actual cause of the error (which is in level 2) is not apparently supplied.

However - by the "highly scientific" method of looking at all the other diagnostic values I discovered that _part_ of the second level text appears to be placed in DB2_TOKEN_STRING. No way of knowing if this is always true - but in this instance it has what I need - which is the reason why an XML validation failed.

Sadly it is still not as good as the job log info. It only includes the latter part of the second level text, not the really useful stuff like the position of the error in the source.

So I'm better off than I was but ... why is it that every time I start to like SQL it throws something like this at me.

Thanks - makes sense but why the hell EXCEPTION is not shown in the diagram and EXCEPTION is ... mutter mutter.

Jon,

EXCEPTION is a synonym for CONDITION. And CONDITION is used to indicate
which SQL condition is requested. CONDITION 1 indicates the last
SQLstatement diagnostic, CONDITION 2 the second, etc.(
IIRC),

Thanks Luis - that appears to be what I was looking for.

The examples all appear to reference "EXCEPTION 1" - e.g. GET DIAGNOSTICS
EXCEPTION 1 error_text = MESSAGE_TEXT;

I cannot find EXCEPTION etc. in the syntax diagram - so it is hard to find
what it means. Any idea?

Jon,

IIRC, if the SQLCA is used the text is truncated automatically to the

first

70 positions.

Have you tried using Get Diagnostics? Again, IIRC, it allows you to
retrieve the full message with the MESSAGE_TEXT option...

If I get an error in embedded SQL then SQLERRMC contains part of the

error

message text - but only the first 70 characters. I can see the full

message

in the log but really don't want to have to retrieve that.

Parts of the manual appear to imply that SQLERRMC can be up to 1,000
characters long but I see no sign of how to achieve that.

Anybody know if there is a simple way to retrieve the full(er) text?
