There are two reserved characters that have special meaning to Greenplum Database:
- The designated delimiter character separates columns or fields in the data file.
- The newline character designates a new row in the data file.
If your data contains either of these characters, you must escape the character so that Greenplum treats it as data and not as a field separator or new row. By default, the escape character is a \ (backslash) for text-formatted files and a double quote (") for csv-formatted files.
