Debug SQL stored procedures and develop your SQL database project with dbForge SQL Complete, a new add-in for Visual Studio and SSMS. When you develop large chunks of T-SQL code with the help of the SQL Server Management Studio tool, it is essential to test the “Live” behavior of your code by making sure that each small piece of code works fine and being able to allocate any error message that may cause a failure within that code.
This article provides an outlook on various types of subqueries in SQL such as select or other T-SQL statements and caveats when using them.
