To find record having null value

Hi All

My requirement is to find the null values in particular column of a file and reject it in case if it contains null values. But the challenge is that I want a common command which can be used across different file, as the position of the column we need to check for different file may get vary.

For ex. in the first file we need to check null values in 2nd & 3rd column, where as in the second file we need to check in 4th, 5th & 6th column.All my files are pipe delimited

Thanks in advance
