    Wow talk about overcomplicating something. Why do you cast @ch as varchar(max) and put it back into a variable that is the same datatype as the original?

    You don't need a variable here to hold your results and the BEGIN END are not serving any purpose at all.

    Here is all you need to do this.

    declare @ch varchar(200)

    set @ch = 'US , CA- I have been there'

    select LEFT(@ch, charindex('-', @ch) - 1)

    Keep it simple. 😀
