SQL Inner join is used to combine records from two or more tables in a database. The inner join is used to select all rows from tables for the match between the columns in tables.

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.
