valdir.marcos, these procedures are for taazz's variant 1?
Yes.
Follow a simplified tutorial on how you can get there (one helping image is attached):
1. Set the connection information;
Depending on the DBMS or RDBMS you are using, you may need to set more properties than just DatabaseName.
Try to activate the connection component to guarantee it is correctly set up.
2. Set the transaction information;
3. Set the query information;
4. Set the query command;
Try to activate the query component to guarantee is correctly set up.
If the connection, transaction and query components are correctly set, steps 5 through 8 should now work as a breeze.
5. Right click on the SQLQuery component to access the field editor;
6. Right click on the field editor blank area to add one, some or all fields;
7. Click on Create button;
8. Click on the chosen field, then on Events tab, then double click on OnGetText and OnSetText.
