Description
EFDDBEngineException is the base exception class for all FireDAC DBMS-related errors.
An EFDDBEngineException object is used as:
- An exception object, raised when a DBMS operation produces an error condition.
- An object describing a warning, stored at connection when a DBMS operation produces a warning condition.
- An object representing a message, stored at connection when a DBMS operation sends a message to a client.
The Errors property contains TFDDBError objects. Each of them corresponds to a single error, warning or message item, produced inside of a single DBMS operation. The Kind property returns a DBMS-independent error kind. The SQL and Params properties allow you to get a failed SQL command.
All FireDAC drivers are implementing their own EFDDBEngineException descendant classes. For example, MySQL driver implements the EMySQLNativeException exception class.
Use a TFDGUIxErrorDialog dialog to display the complete information about the FireDAC / DBMS error.
