Question

In MySQL, when I try to insert a backslash into my table, it does not accept it and gives me the content without the backslash.

id is set to auto increment:

Code:

INSERT INTO gender (sex, date) VALUES (
'male are allowed \ female are not allowed', "2012-10-06")

How do I insert a literal backslash?

Notes about escape sequences:

Escape  Sequence    Character Represented by Sequence

\0     An ASCII NUL (0x00) character.
\'     A single quote (“'”) character.
\"     A double quote (“"”) character.
\b     A backspace character.
\n     A newline (linefeed) character.
\r     A carriage return character.
\t     A tab character.
\Z     ASCII 26 (Control+Z). See note following the table.
\\     A backslash (“\”) character.
\%     A “%” character. See note following the table.
\_     A “_” character. See note following the table.

Answer 1

You need to escape your backslash :

INSERT INTO gender
(sex, date) VALUES (
'male are allowed \\ female are not allowed',
"2012-10-06")
