How can I run several SQL files using a single SQL file?

edit

To run several SQL files using a single SQL file, you can use the "source" command to include the other SQL files in your main SQL file.

Assuming that you have three SQL files named "file1.sql", "file2.sql", and "file3.sql", and you want to run them in a single SQL file, you can create a new SQL file called "main.sql" and include the other files using the following syntax:

source file1.sql;
source file2.sql;
source file3.sql;

When you run the "main.sql" file, it will execute the commands from all three files in the order they are listed.

Note that the "source" command may vary depending on the database system you are using. Some systems may use "include" or "load" instead of "source".
