Is there a keyboard shortcut to insert a <NULL> into a given SQL field?

I th ought I read somewhere it was ALT-F4 but that doesn't seem to work.

Thanks!

BTW: ALT-F4 actually closes SQL all together.. so don't try it :)

What is ur client ? Query Analyzer ? ASP ? VB ? Java ?

I don't know about keyboard shortcuts but
If its a query:
if the table has fields (a,b,c,d,e,f,g,h)
Insert into tbl (a,b,e,g) values('aa','bb','ee','gg')
Inserts Null to all fields (if no defaults specified) not in the list - ie. for the fields c,d & h

if u want to purposely put Null into a field u can use
Insert into tbl (a,b,c,d) values('aa','bb',Null,Null)
Inserts Null to all fields c & d and for the fields e,f,g & h as well

SQL 2K..

My issue is that I'm testing on an already existing date field, and I need to "reset" the record
if you will by NULL'ing out the date field.

U have a table and u want to change some field content to Null ?

Update urTable set urDateOrAnyField = Null where urCondition
Run the proper statement on the query analyzer.
If u tell us what ur table & field names and what u want to do as well, v can give the exact solution.

Are you trying entering it thru Enterprise Manager?
then try ctrl + 0 (zero)

That is not a good practice. For large number of data, it will be very slow. Also it would throw error if you update an unique column value with a value which is already available

Thank you shallu1_gupta and Yossi Bressler. I've been looking everywhere for that.

@madhivanan, sometimes you just want to reset one value back to what is was at the beginning of the test. It is a major pain in the you know what to have to write a query each time.
