Question

I want to update a row which is in format like this ABC - DEF - GHI - ABD,
Using a cmd like this UPDATE tbl SET col = Replace(col,@var, '') WHERE Pk=something. How can I remove the trailing or leading hyphens? For exmaple if @var is GHI, after replace, row value should be ABC-DEF-ABD or if @var is ABC then value should be DEF – GHI – ABD.

Answer 1

First of all, agree completely with comment above.. Change teh data sschema to not store delimited lists of values in database column.

But, if this is not possible, Try this:

Update Table Set 
   colName = Replace(Replace(colName, '- ' + @var, ''), @var + ' -', '')
Where pk = @pk
