Script to obtain datadictionary from a SQL2000 db

,

This script creates a stored procedure that, when executed, queries the system tables of any SQL2000 database to return a complete, ordered datadictionary. *Warning**This script only works on tables which have the description property filled out as my main purpose was to query the extended property description feature new to SQL2000. If you have not filled out any descriptions on your tables or columns, it will not return any data (try completing a couple of column descriptions to test it).

Simply run the query in Query Analyzer (make sure you specify a database) to create the stored procedure. Then call the procedure by typing "exec datadictionary" to return an up to date datadictionary which can be quickly exported to Excel, Word, etc.

Although it is preferred to use the schema views instead of the system tables, this is an easy way to view the table and column description extended properties which are new to SQL 2000. Be aware that when migrating to future versions of SQL, the system tables could change.
