Check if `isql` queries succeed

Question

Is there any way to check if an isql query has failed? It seems isql returns 0 whether queries succeed or not, only returning false if there was a error connecting to the server. How can I determine whether or not my Sybase queries work from the command line?

Answer 1

--retserverror seemed to be what I was looking for.

Answer 2

Just Run this commands

 isql -v SERVERNAME Username password

At the prompt run your query

>SELECT COUNT (*) FROM table

+------+
|      |
|  100 |    
+------+

If you dont get any value back there is some problems
