The keyword affects where the file is expected to be found:
LOCAL
• If is specified, the file is read by the client program on the client host and sent to the server.
LOCAL
The file can be given as a full path name to specify its exact location. If given as a relative path
name, the name is interpreted relative to the directory in which the client program was started.
When using with
LOCAL
This is not the directory determined by the value of
but rather the operating system's temporary directory, and is not configurable in the MySQL Server.
(Typically the system temporary directory is
Windows.) Lack of sufficient space for the copy in this directory can cause the
statement to fail.
• If is not specified, the file must be located on the server host and is read directly by the
LOCAL
server. The server uses the following rules to locate the file:
• If the file name is an absolute path name, the server uses it as given.
• If the file name is a relative path name with one or more leading components, the server searches
for the file relative to the server's data directory.
• If a file name with no leading components is given, the server looks for the file in the database
directory of the default database.
In the non-LOCAL case, these rules mean that a file named as
