If you want to change the default settings to allow you to edit more than the 200 rows at a time, or select more than 1000 rows, which are the default settings for Microsoft SQL Server. To modify “Edit Top 200 Rows” or “Select Top 1000 Rows” settings do the following:
In SQL Server 2008 Management Studio, go to “Tools” -> “Options” -> “SQL Server Object Explorer” -> “Commands“.
Now in the right-hand side “Table and View Options” section, you can change either:
Value for Edit TopRows command, to a value greater than or less than 200.
Value for Select TopRows command, to a value greater than or less than 1000.
By specifying a value of 0, SQL Server will return all rows. (If you sql tables are really large, you will definitely NOT want to set these values to 0.
