Fixed problem with Innobase and signals on Solaris

@item \0

An ASCII 0 (@code{NUL}) character.

@findex \' (single quote)

@findex single quote (\')

@item \'

A single quote (@samp{'}) character.

@findex \" (double quote)

@findex double quote (\")

@item \"

A double quote (@samp{"}) character.

@findex \b (backspace)

@findex backspace (\b)

@item \b

A backspace character.

@findex \n (newline)

@findex newline (\n)

@item \n

A newline character.

@findex \t (tab)

@findex tab (\t)

@item \t

A tab character.

@findex \r (carriage return)

@findex return (\r)

@findex carriage return (\r)

@item \r

A carriage return character.

@findex \b (backspace)

@findex backspace (\b)

@item \b

A backspace character.

@findex \' (single quote)

@findex single quote (\')

@item \'

A single quote (@samp{'}) character.

@findex \t (tab)

@findex tab (\t)

@item \t

A tab character.

@findex \" (double quote)

@findex double quote (\")

@item \"

A double quote (@samp{"}) character.

@findex \z (Control-Z) ASCII(26)

@findex (Control-Z) \z

@item \z

ASCII(26) (Control-Z).  This character can be encoded to allow you to

go around the problem that ASCII(26) stands for END-OF-FILE on windows.

(ASCII(26) will cause problems if you try to use

@code{mysql database < filename}).

@findex \\ (escape)

@findex escape (\\)

You should use @code{mysql_real_escape_string()} instead!

This is identical to @code{mysql_real_escape_string()} except that it takes

the connection as the first argument. @code{mysql_real_escape_string()}

will escape the string according to the current character set while @code{mysql_escape_string()}

does not respect the current charset setting.

@findex @code{mysql_fetch_field()}

@node mysql_fetch_field, mysql_fetch_fields, mysql_escape_string, C API functions

@subsubheading Description

Encodes the string in @code{from} to an escaped SQL string, taking into

account the current charset of the connection, that can be sent to the

server in a SQL statement, places the result in @code{to}, and adds a

terminating null byte.  Characters encoded are @code{NUL} (ASCII 0),

@samp{\n}, @samp{\r}, @samp{\}, @samp{'}, @samp{"}, and Control-Z

(@pxref{Literals}).

This function is used to create a legal SQL string that you can use in a

SQL statement. @xref{String syntax}.

The string in @code{from} is encoded to an escaped SQL string, taking

into account the current character set of the connection. The result is placed

in @code{to} and a terminating null byte is appended.  Characters

encoded are @code{NUL} (ASCII 0), @samp{\n}, @samp{\r}, @samp{\},

@samp{'}, @samp{"}, and Control-Z (@pxref{Literals}).

The string pointed to by @code{from} must be @code{length} bytes long.  You

must allocate the @code{to} buffer to be at least @code{length*2+1} bytes

Don't free the key cache on @code{FLUSH TABLES} as this will cause problems

with temporary tables.

@item

Fixed problem in Innobase with with other character sets than latin1 and

alarms on Solaris.

@item

Fixed a core-dump bug when using very complex query involving

@code{DISTINCT} and summary functions.
