Of course you can also select this information from the ddl's internal views yourself, the relevant DBD module source should provide useful statements.

What if I have a number of columns? in Perl DBI, I need to create a temp table of those columns and generate a ddl of the temp table on Database A. Then, the DDL of the temp table will be loaded on database B. Do you have any hints on how to do that? Mike

Zhris Enthusiast May 9, 2015, 3:51 PM Views: 16435 Re: [db_fan] Perl DBI: store the ddl of a column in a variable I'm not familiar with DB2, have you looked into the syscat tables, specifically the syscat.columns table? It appears you can select all the information you require in one hit off this table. Apologies, are you stuck on using Perl's DBI module, as oppose to how to get the information as per your original post? Chris (This post was edited by Zhris on May 9, 2015, 4:06 PM)
