I have a real problem with calling a stored procedure on MS SQL Server
from Ruby-DBI. I have no problems with connections or calling queries.
I can even call the Stored procedure with "exec Test 'test'" and the
stored procedure inserts the value text into a Test table. However, if
I try to use the bind_param to add the input params to a stored
procedure to make my class alitte more friendly it ERRORs.
OUTPUT ____
Connection Successful !!!
Preparing SQL Query: exec Test
Executing SQL Stmt
Error INTERN (0) [RubyODBC]Too much parameters
