Database Tables

2012/06/13


Today I was asked for "a list of all tables in all databases" on a particular instance of SQL Server.  Knowing what was actually required was all "User" tables in all "Accessible" "User" databases I wrote the script below . It will return the ServerName, DatabaseName, SchemaName and TableName of all the user tables in all online read-writeable non system databases.

Hopefully someone will find this useful ;)

/*
