Column Size Checker

By Richard Doering,

Introduction :

This is a utility to show how well your column sizes suit your data (or vice versa)..

Usage :

By default, the script will run for every table in the database you run it in.

This may prove quite time consuming so set the @SCHEMA and @TABLE variables at the top of the script to the schema and table name respectively to analyse only one table.

Output :

The output is fairly self explanatory i.e. the name of the name, it's rowcount and column details.

For each column, 3 length values are given (where appropriate)

  1. COLUMN_MAX_LENGTH is the defined length of the column.
  2. DATA_MIN_LENGTH is the lengthof the smallest data found in the column
  3. DATA_MAX_LENGTH is the length of the largest data found in the column

I had fun creating it, I hope someone (who isn't using SSIS 2008 Data Profiler!) finds it useful.
