When the weekly maintenance ran the Update statistics died on this table saying there was a null value in a non null field. So I ran DBCC Checktable against the table and discovered the same type of error. I am hesitant to loose data and since the minamum repair level recommended by DBCC was to allow data loss I decided I would like to find the offending record. So after some digging I discovered the following script returned some odd results.

select L_EXCLUDETRANS, count(*) from ADVANCED.BIF041 group by L_EXCLUDETRANS 

this returned
L_EXCLUDETRANS Count
0 107,242,316
0 1
1 747,242

So the question became why is it picking up a second 0 as a unique value. My second problem became how to find the record with the bad 0. I have tried selecting by zero selcting by 1 selecting by not in 0 or 1; not equal to 0; not equal to 1 I have tried restoring the DB to a different environment and the problem follows. I have imported the table alone into a new DB and the problem does not follow. I have tried to use Data compare in visual studios but it states all records match between the restored DB and the DB with the copied table. Does anyone have any tricks or tips to find this record?

Try checkDB with data purity. See if it gives you any more useful errors

I tried that and got the same error as before.

row ID 21. Column 'L_EXCLUDETRANS' was created NOT NULL, but is NULL in the row

I have looked at ROW 21 extensively even removing it in my TEST server were I did the restore and still get the error so I am assuming that does not actually point to record 21

Thank you, this is all I needed.

Row error: Object ID 292196091, index ID 1, partition ID 72057617438736384, alloc unit ID 72057617450598400 (type In-row data), page ID (7:4432313), row ID 21. Column 'L_EXCLUDETRANS' was created NOT NULL, but is NULL in the row.


Right, what's the primary key of this table?
What's the data type of L_EXCLUDETRANS?

Run the following save the results to a text file and attach that file to your post.

Gail,

Thank you for your help I actually found the row I needed to fix and was able to get this problem taken care of. It has helped me realize though that I have a great deal to learn about DBCC and need to read up some more on it.
