Hi ! For some reasons, I have no other solutions but to use a TDatase to perform SQL operations on a database. They can be basic SQL commands (selection...) and calls to stored procs. Actually, I am exactly using the example that can be read at page 17-12 in the developper's guide, under title: 'Executing parameterized SQL Statements'. Basically, u use the TDatabase.Execute method, specifying the SQL Statement to perform, and the params needed by that statement. Eveything is OK when i use simple 'hardcoded' SQL statements, but as soon as i try to pass Params, i get an error when trying to execute, saying ' could not find object ', although im certain that the TParams object im passing as a parameter is valid. Im puzzled. If anyone can help me, thx a lot...
