Hello,
I have a field and the data is in the format below:
12-FLA-2-02
I am trying to update just the first part of the data before the first dash which is 12 to another field that is a single numeric value.
update table set table.field = LEFT(table.field, CHARINDEX('-', table.field)-1) where table.field is null
I am trying to manipulate this script below, but I cannot figure out how to update just the 12 before the dash.
Thanks
Larry

You can use REPLACE function as well.

declare @STR as table( val varchar(20))

insert @STR

select '12-FLA-2-02'

declare @update varchar(20)='11111'

select * from @STR

update @STR set val=replace(val,LEFT(val, CHARINDEX('-', val)-1) ,@update)

select * from @STR

select * from @STR

You can, but I wouldn't recommend it:

declare @STR as table( val varchar(20))

insert @STR select '12-FLA-2-02'

insert @STR select '12-FLA-2-12'

declare @update varchar(20)='11111'

select * from @STR

update @STR set val=replace(val,LEFT(val, CHARINDEX('-', val)-1) ,@update)

select * from @STR

Yes makes sense.Thanks for pointing that out..
