10.1.5 NULL Values

The NULL value means "no data." NULL can be written in any lettercase.

Be aware that the NULL value is different than values such as 0 for numeric types or the empty string for string types. See section Problems with NULL.

NULL may be represented by \N when using the text file import or export formats (LOAD DATA INFILE, SELECT ... INTO OUTFILE). See section LOAD DATA.
