When the company's production database is established, the user name used in the program is ABB, and all the tables belong to ABB. In this way, the permissions of ABB users are almost unlimited, he can drop any table. Another time a few days ago, the developer mistakenly dropped a table.
According to the original plan, the database was changed last week (because the HDD logic was damaged) and upgraded to 10 Gb by the way. therefore, during the upgrade, all objects under the abb user are moved to the ABC user. create ABB and use tokens to create synonyms for all objects of ABC users. in this way, the program can be directly used without modification.
After the entire upgrade process is complete, open the web for users to use. however, in the production line report, the program cannot be opened. At first, the program may be considered as a BDE version problem. After modifying the BDE parameter, the program can be opened, but the execution is very slow and tested by developers, the synonym created for the stored procedure cannot be used in the program, and the program is changed to ABC. OK after XXXX.
At present, although this problem has been solved, the synonym is clearly set up and available on the webpage, but it is invalid in the C ++ program, and it is still puzzling.
