Compare Parallel Data Streams

By nhamilton,

This a script to compare two parallel data streams, in my case production and QA.  Two extracts were created and a mapping table was created as a look-up between old and new recordids.  A final table TestResults was created to hold the results of the comparison.  The comparison table names and join syntax are controlled by variables. 
The script uses syscolumns to find the common column names and compares each row in the two tables, column by column and inserts any differences in to the results table.
The comparisons support nulls and casts any column with the word 'date' in the name as a datetime before conmparing.
