Name is valid if it's either equal to or starts with the value stored in the mysql options. If the value in the options is NULL then no name is valid.

Note that we rely that the options name, if supplied, is normalized before being stored.

Escapes special characters in a string for use in an SQL statement.

Escapes special characters in the unescaped string, taking into account the current character set and sql mode of the connection so that is safe to place the string in a mysql_query(). This function must be used for binary data.

This function does not work correctly when NO_BACKSLASH_ESCAPES sql mode is used and string quote in the SQL statement is different than '\''.

Deprecated:
This function should not be used. Use mysql_real_escape_string_quote instead.
See also
mysql_real_escape_string_quote
Parameters
[in]mysqlMySQL connection structure.
[out]toEscaped string output buffer.
[in]fromString to escape.
[in]lengthString to escape length.
Returns
Result value.
Return values
!=(ulong)-1 Succeeded. Number of bytes written to the output buffer without the '\0' character.
(ulong)-1Failed. Use mysql_error() to get error message.

Escapes special characters in a string for use in an SQL statement.

Escapes special characters in the unescaped string, taking into account the current character set and sql mode of the connection so that is safe to place the string in a mysql_query(). This function must be used for binary data.

This function should be used for escaping identifiers and string parameters.

Parameters
[in]mysqlMySQL connection structure.
[out]toEscaped string output buffer.
[in]fromString to escape.
[in]lengthString to escape length.
[in]quoteString quoting character used in an SQL statement. This should be one of '\'', '"' or '‘’ depending on the parameter quoting applied in the SQL statement.
Returns
Result value.
Return values
!=(ulong)-1 Succeeded. Number of bytes written to the output buffer without the '\0' character.
(ulong)-1Failed.
