Hi All,

I want to know how to add percentage symbol(%) to my final sql statment column names in stored procedure, query below

set @finalSelect = 'SELECT NAME,State,TotalPop, ' + @parameter +'_Pop%
FROM
'

Result: NAME, State, TotalPop, White_Pop% (column names)


When I add % symbol it throws an error:

Msg 102, Level 15, State 1, Line 1
Incorrect syntax near '%'.

Any idea how to add percentage(%) symbol??

Personally I would not use symbols like that in column names. That type of thing should done in the front end.

The direct answer to your question however is you have to wrap the column name inside square brackets.


set @finalSelect = 'SELECT NAME,State,TotalPop, [' + @parameter +'_Pop%]'



Be careful here, it looks like you are receiving a parameter and then directly executing the dynamic sql you are creating. This is vulnerable to sql injection.
