sql - Executing a command string with GO at the end -

I need to execute a command string with the use of the Geo command at the end

 < Code> exec ('SELECT * FROM tblTmp where id = 1 gO')   
 after my execution  
 
 'GO' has the wrong syntax.   
 If I execute  exec ('SELECT * FROM tblTmp GO')  everything is fine  
 What's the problem here?  
 Thank you.   
 
 
 You do not need to use GO for a single SQL statement. Only when you are batching several statements in a script, you need to use a separator. In addition, if you are performing these programs, you should use the semicolon (;) statement terminator instead of geo to separate your SQL statement.  
 This is an easy task.
