A quick example:

Can I use select case in "stored procedure ???
If yes, can someone be kind to give me a sample ?? Thanks From SQL-newbie
Yes, something like this:
UPDATE TableName SET ColumnName = CASE WHEN <Condition1> THEN <Value1> WHEN <Condition2> THEN 'Value2' ELSE 'Value3' END WHERE <Some condition to select the rows> -- Vyas, MVP (SQL Server) http://vyaskn.tripod.com/ [quoted text, click to view] "Agnes" <agnes@dynamictech.com.hk> wrote in message news:%23EBiSjubEHA.1644@tk2msftngp13.phx.gbl... > How about update statment ? > After i select * from table, i need to update it at once.. but It depends on > the condition, > Can update got the 'case' also ?? > > "Agnes" <agnes@dynamictech.com.hk> ¦b¶l¥ó > news:eiIlaFubEHA.2812@tk2msftngp13.phx.gbl ¤¤¼¶¼g... > > I understand and try it later .

How about update statment ?
After i select * from table, i need to update it at once.. but It depends on the condition, Can update got the 'case' also ??

I need to specified the column ??
infact, i got several column may be update (which depends on the case parameter) it seems wrong syntax if my code like this :- update mytable case @type when 'A' then a = a + 1 when 'B' then b = b + 1 end "Narayana Vyas Kondreddi" <answer_me@hotmail.com> ¦b¶l¥ó news:u$7yJJvbEHA.2292@TK2MSFTNGP09.phx.gbl ¤¤¼¶¼g...

This is why posting what you have in mind is so helpful.
No, you cannot do this. SQL is not that kind of language. You can easily to this using something like: update mytable set A = case when @type = 'a' then A + 1 else A end, set B = case when @type = 'b' then B + 1 else B end, where ... It could also be done using dynamic SQL, but that is very messy. -- ---------------------------------------------------------------------------- Louis Davidson (drsql@hotmail.com) Compass Technology Management Pro SQL Server 2000 Database Design http://www.apress.com/book/bookDisplay.html?bID=266 Note: Please reply to the newsgroups only unless you are interested in consulting services.
