This stored procedure retrieves all the columns of each table in every database.

create procedure SP_GetAllColumnsFromAllDB/*---------------------------------------------------------------------- Procedure to retrieve columns of all the databases-- Usage   : exec SP_GetAllColumnsFromAllDB-- Logic is: First get all the DB into a master cursor     excluding system databases-- (1 Master, 2 tempdb, 3 model, 4 msdb, 5 pubs, 6 northwind) -- if you want to include this then just remove the   where condition from master cursor i.e.  where dbid≫6-- loop through master cursor -- insert all table name into a temporary table #tmp_table-- Create a inner cursor for tables-- loop through this cursor-- insert all the columns (into #final_table) of looping table(in Master looping database)-- delete the table names from #tmp_table to be able to get the tables of next database
