Description
The base class for custom script commands.
The FireDAC SQL Script engine is fully extendable and allows to create custom script control commands. Use the TFDScriptCommand class as a base class for custom script commands. The command developer must implement the following virtual methods:
- Keywords--returns the list of the keywords, which run this command.
- Help--returns the command help.
- Parse--parses the script and prepares the command for execution.
- Validate--runs the command in script validation mode.
- Execute--runs the command in actual execution mode.
The command class must be registered with the SQL Script engine using the FDScriptCommandRegistry().AddCommand(...) call.
