Answer» How to disable overwrite instead of inserting text while typing in SQL? Some time all of sudden SQL Server Management studio started behaving something different. Once we are writing any query this will overwrite the text in place of typing new words. And if you will try this on Notepad and other APPS all works fine. In SSMS we can actually DEFINE the behavior of the text editor, and alternate between Insert and Overwrite. To overcome this we need to check the status bar of SSMS as GIVEN below. In below screen in status bar there is text "OVR" written which means this will overwrite the text. and double CLICK on this "OVR" this will be converted to "INS" which means it is now ready.
