When the plsql tool executes update submission, there is no prompt box Indicating "Submit current transaction". Because PLSQL can check "no longer display this information" under the prompt "Submit current transaction ", once this option is selected, it will not be prompted again, but it is often found that there will be misoperations in the production database and it will be embarrassed to automatically submit it if you are not careful, you can perform the following settings to restore the www.2cto.com tool-preferences-User Interface-options-DSA dialog box-the content is as follows; a dialog box containing "no longer show this information" is displayed; you can delete the row CharSetMismatch @ RIM40 = 1CharSetMismatch @ character = 1CharSetMismatch @ RIS4T = 1 AutomaticStatisticsDisabled = 1 Commit = 6 Delete Commit = 6 and save it! PLSQL does not need to be restarted.
