Hi All,

I apologize if this is not the right place to post this question. However I wish to calculate the variable length key size.Upon some reserach i was able to conclude that to Calculate the variable-length data size: determine how much space is used to store the columns within the row:

The expected row length for dynamic-sized rows is calculated using the following expression:

3 + (number of columns + 7) / 8

+ (number of char columns)

+ (packed size of numeric columns)

+ (length of strings)

+ (number of NULL columns + 7) / 8


Do we have a better and a easier way to calculate this as i wish to fetch these variables and do the calculation thru a perl script.
