We have had a couple of sites now that have had the error message basically stating we had run out of uniquifiers on this one table's clustered index.
In this table there is a tremendous number of "null" values generated on the clustered index column that are eventually deleted from the table leading to exhaustion of the uniquifiers over time.
I did some testing on a small table and used the dbcc ind and dbcc page to find out how uniquifers worked. I still haven't figured out nor have my web searches been able to find a way to find the last used "uniquifier which we need to find in order to prevent this error from occurring at other sites. From my testing I understand how uniquifiers work and I realize that on this table's column I would have more than "one" last uniquifier because the column allows non-unique values other than just nulls. I only need to find the last uniquifier for the "null" values in the column.
I would appreciate any help to find the last used uniquifier.
Thanks
Sue
