Sorry i did not replace my table plan, now i replaced my plan with the table which i have give.
More issues. You renamed the table to TABLE2 and the column to COL10. Issue, there is no COL10 in the DDL for TABLE2. There is a TCOL10 and it is declared as a float. The value you are comparing this column to appears to be a BIGINT not a float.
You still need to answer all the other questions I asked earlier as well.
You also stated in your initial post:
I am deleting some 200000 records from 5000000 rows.
The estimated execution plan indicates that you may actually be trying to delete 3,655,550 rows of data.
Please answer all the questions you have been asked and explain exactly what it is you are trying to accomplish. Without these answers, I am done trying to help. Sorry.
