AW: usinfg sql to delete records, but some records are locked by users

Hi,

If you are on release 6.1 or higher, you may add SKIP LOCKED DATA to your
Update or Delete Statement.

Here the documentation out of the SQL Reference:
SKIP LOCKED DATA
Specifies that the select-statement, searched UPDATE statement (including a
searched update operation in a MERGE statement), or searched DELETE
statement that is prepared in the PREPARE statement will skip rows when
incompatible locks are held on the row by other transactions. These rows can
belong to any accessed table that is specified in the statement. SKIP LOCKED
DATA can be used only when isolation level NC, UR, CS, or RS is in effect.
SKIP LOCKED DATA is ignored if it is specified when the isolation level that
is in effect is RR.

Mit freundlichen Grüßen / Best regards

Betreff: usinfg sql to delete records, but some records are locked by users


Hi everyone
I am using SQL to delete records from a file. Nothing fancy
delete from filea where rectype = '1'

On development, this just flies through
On production - not the same
I think that its is because some users may have some of these records
locked
Apart from asking the users to temporarily sign off (LAST RESORT)
Is there a way within SQL to bypass those records that are locked and
delete all the records that are not locked

I have the luxury of coming back to those non-deleted records later

As always, any and all responses MUCH appreciated
Thanks in advance
