How can I correct MySQL Load Error

问题:

I'm not quite sure a similar question to this was closed by I'm trying to execute the following MySQL program.

mysql -e "load data local infile \
'/tmp/ept_inventory_wasp_export_04292013.csv' into \
table wasp_ept_inv fields terminated by ',' \
lines terminated by '\n' ;"

at the bash command line and get this error

ERROR 1148 (42000) at line 1: The used command is not allowed with this MySQL version

How can I work around this problem?

I am actually running this command from a Python program, but pulled the command out to try fiddling with it at the bash command line.

I've seen how I can modify my.cnf (local-infile), but I do not want that global a change if I can avoid it.

Here's the MySQL version.

mysql Ver 14.14 Distrib 5.5.31, for debian-linux-gnu (i686) using readline 6.2

As documented under Security Issues with LOAD DATA LOCAL:

To deal with these problems, we changed how LOAD DATA LOCAL is handled as of MySQL 3.23.49 and MySQL 4.0.2 (4.0.13 on Windows):

• By default, all MySQL clients and libraries in binary distributions are compiled with the --enable-local-infile option, to be compatible with MySQL 3.23.48 and before.

• If you build MySQL from source but do not invoke configure with the --enable-local-infile option, LOAD DATA LOCAL cannot be used by any client unless it is written explicitly to invoke mysql_options(... MYSQL_OPT_LOCAL_INFILE, 0). See Section 20.6.6.49, “mysql_options()”.

• You can disable all LOAD DATA LOCAL statements from the server side by starting mysqld with the --local-infile=0 option.

• For the mysql command-line client, enable LOAD DATA LOCAL by specifying the --local-infile[=1] option, or disable it with the --local-infile=0 option. For mysqlimport, local data file loading is off by default; enable it with the --local or -L option. In any case, successful use of a local load operation requires that the server permits it.

• If you use LOAD DATA LOCAL in Perl scripts or other programs that read the [client] group from option files, you can add the local-infile=1 option to that group. However, to keep this from causing problems for programs that do not understand local-infile, specify it using the loose- prefix:

  [client]
  loose-local-infile=1
  

• If LOAD DATA LOCAL is disabled, either in the server or the client, a client that attempts to issue such a statement receives the following error message:

  ERROR 1148: The used command is not allowed with this MySQL version

The workaround for this is to modify the command line mysql -e to pass in the --local-infile=1 argument like this:

mysql --local-infile=1 -u username -p `

Then run the LOAD DATA LOCAL INFILE command again.

回答3:

local-infile needs to enabled on both the server and the client. You can accomplish this by adding local-infile = 1 to the appropriate section in each end's my.cnf (Unix) or my.ini (Windows) file. For example, on the client:

[client]
local-infile = 1

You can also enable this at runtime on the server by setting the system variable local_infile:

SET GLOBAL local_infile=1;

However, you still need to enable it on the client. You can do this at runtime by adding a command-line parameter to the mysql command:

mysql --local-infile=1 ...

If you're using Amazon Web Services RDS, you can configure the server setting by editing or creating a Parameter Group. Look for the local_infile parameter. You may need to restart your server after applying the changes.

My guess is that your MySQL server does not have LOAD DATA LOCAL enabled. See this section of MySQL documentation:

If LOAD DATA LOCAL is disabled, either in the server or the client, a client that attempts to issue such a statement receives the following error message:

ERROR 1148: The used command is not allowed with this MySQL version
