It is giving error:
Msg 156,state 1,Line 6
Incorrect syntax near the keyword except.

You are probably using SQL Server 2000

EXCEPT operator works only in SQL Server 2005+

Indeed. Another version:

;with Remove

as (

select a.c1

from t1580 a

except

select a.c1

from T1580 a

inner join T2115 b on a.C301289100 = b.C1000000161

and b.C7 < 5

)

delete a

from t1580 a

join Remove on a.c1 = Remove.c1

It's about time you started thinking for yourself. Tell us what you have tried.

Slowly drip-feeding your requirements is unhelpful and wastes people's time.

Please read the following article, it may help you write the query (queries) you need to delete the records and control the size of the transaction log.

When you say it isn't executing, what is it doing? Are you getting some kind of error message(s)? If so, we need to know. Just telling us it isn't running doesn't tell us a thing.

Pretty sure you were getting syntax errors.

Try the following:

DECLARE @BatchSize INT

SET @BatchSize = 1000;

WHILE @BatchSize <> 0

BEGIN

with Remove as (

select

X.id1

from

X

except

select X.id1

from

X

inner join Y

on X.id2 = Y.id2)

Delete top(@BatchSize) X

from

X

join Remove

on X.id1 = Remove.id1;

SET @BatchSize = @@rowcount;

END
