Considerations
The FFLUSH stored procedure writes only data terminated with a newline character to the file. Data that is not terminated with a newline character is retained in the buffer.
To call the FFLUSH stored procedure, you must have the w privilege on the file; otherwise, the INVALID_OPERATION exception will be thrown. If the data length of the buffer exceeds the maximum line length specified by FOPEN, the INVALID_MAXILINESIZE exception will be thrown.
