Subj:   Compare 2 tables in 2 different databases
 
From:   Bakthavachalam, Roopalini

Hi Forum,

I have 2 databases with 100 odd tables and would like to generate a report on the structure discrepancies which includes ( column names ,type, index, column length?.). One crude way , I was thinking , was to run the ?SHOW TABLE? for all the tables in a bteq script and compare the outputs. Another way was with a query below. Could anyone give me suggestions of any better way. I am sure there is!

     SELECT
     TABLENAME,
     COLUMNNAME,
     COLUMNFORMAT,
     COLUMNTITLE,
     COLUMNTYPE,
     COLUMNLENGTH,
     NULLABLE

     FROM
     DBC.COLUMNS
     WHERE DATABASENAME = 'DEV_ABC'

     MINUS

     SELECT

     TABLENAME,
     COLUMNNAME,
     COLUMNFORMAT,
     COLUMNTITLE,
     COLUMNTYPE,
     COLUMNLENGTH,
     NULLABLE

     FROM
     DBC.COLUMNS
     WHERE DATABASENAME = 'PRD_ABC'

Thanks

Roopalini
