How Can I Generate Rows in MySQL Using External Files?

An alternative to using external files to generate MySQL row data

MySQL does not support Oracle's traditional syntax for generating rows using the CONNECT BY clause. However, there are some alternatives to achieve this functionality in MySQL.

One way is to create a temporary table or use an external file containing the required number of rows. For example, you can create a file with the following content:

<code>1
2
3
4
5
6
7
8
9
10</code>
Copy after login

You can then import this file into MySQL using the LOAD DATA INFILE command:

<code>LOAD DATA INFILE 'filepath.txt' INTO TABLE temp_table;</code>
Copy after login

This will create a temporary table named temp_table containing the specified number of rows. You can then join this table with other tables in queries.

Limitations

However, this approach has some limitations:

  • It requires creating an external file before running the query.
  • It may not be as efficient as using the built-in row generator in other relational database management systems.
  • It cannot dynamically generate any number of rows.

Nevertheless, this method provides a workaround for MySQL's lack of built-in row generators.
