Solved: loading local data is disabled

Sure, here is the beginning of the article. Please note that you will need to add the specific code in the places I’ve marked.

For database administrators and developers, working with SQL isn’t always a walk in the park. Particularly challenging is when you want to load local data but find that this feature is disabled.

As experts in the field, we understand the problem through and through and have come up with a solution to help you get past this hurdle. This issue usually comes up because, for security reasons, MySQL disables the local-infile option by default. Don’t be dismayed, though, as there are ways to enable this feature.

For instance, MySQL command-line client can start with –local-infile[=value] to explicitly enable or disable the local_infile system variable in MySQL Server.

The local-infile variable provides the user with the ability to read files located on the server host using the LOAD DATA INFILE statement.

MySQL –local-infile startup option

One way to load local data in MySQL is by using the –local-infile startup option. This option can be set to either 0, 1, or an empty value.

--local-infile[=value] 

In the code above, replace “value” with 0 to disable LOCAL for LOAD DATA INFILE, 1 to enable it, or leave it empty to not set the value explicitly at startup, which leaves the value as compiled into the server.

The LOAD DATA INFILE Statement

The LOAD DATA INFILE statement reads rows from a text file into a table at a very high speed. It proves very advantageous when you have to populate a table with a large number of rows. Let’s see how this works in practice.

LOAD DATA INFILE 'path/to/your/file.csv'
INTO TABLE your_table_name
FIELDS TERMINATED BY ',';

In the above sample code, replace ‘path/to/your/file.csv’ with the path to the actual .csv file you want to load and ‘your_table_name’ with the name of your table. Also, if your data values are separated by another character (instead of a comma), change the ‘,’ to that character.

The process above should solve your challenge and get you back in action. Loading local data isn’t as thorny as it initially appears, as long as you know how to go about it and are mindful of the security implications.

In conclusion, the maneuver to enable loading of local data involves initializing the local-infile variable using MySQL command-line client or using mysql options file (.my.cnf or my.ini etc.). Also, it’s crucial to realize that enabling loading local data can be a security risk, especially in shared hosting environments. Therefore, it should be enabled only when necessary and disabled once the requirement is over.
