| No need to be rude about it. Your question was unclear (and it still is!) so you leave it up to us to guess what it is you want. Now, is this it? ->select * from class where custsize is null and cid is null- LumbagoMy blog-> http://thefirstsql.com/2011/02/07/regular-expressions-advanced-string-matching-and-new-split-function-sql-server-2008-r2/ |

| hmmm, ok will explain again with more detailed.For Example: I created one table in that same created table I have 10columns, here is the table diagram and data in the columns.Custname custsize cid custmarks custper CustNo MCA 25 100 10 5 NULLMTECH 10 101 NULL 2 7BETCH 20 102 30 NULL 5BCA NULL NULL 40 10 9like this so on..... different columns have NULL values.so here what I need is, I need to get output of the columns who are have only NULL values.It does not mean if we give this command "WHERE Column1 IS NULL AND Column2 IS NULL AND...every time we need to write colname NULL and colname NULL we cannot write this for 10times.So, I think you got my Question. |

| For Example: we have 25columns, in 25columns in each column we have one NULL value,it does not make any sense if we go on write the command like this.WHERE Column1 IS NULL AND Column2 IS NULL AND Column3 IS NULL AND Column4 IS NULL AND Column5 IS NULL AND Column6 IS NULL AND Column7 IS NULL AND Column8 IS NULL AND..........so, is there any command to get only NULL values instead of writing 25times. |
