Question

I wrote a stored procedure and want to execute it within a Rake task.

Before calling the stored procedure (through the “call” statement) I should create the procedure with the source command which fails because of the following error:

Mysql2::Error: You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to
use near ‘source import_legacy_database.sql’ at line 1: source
import_legacy_database.sql

This error happens when the following line is executed:

ActiveRecord::Base.connection.execute "source import_legacy_database.sql"

The same command “source import_legacy_database.sql” runs fine when in the console, but not in the Rake task.

If I don’t call that command then

ActiveRecord::Base.connection.execute "call import_legacy_database()"

fails because the database doesn’t find the procedure because it does not exist.

Thanks in advanced.

I finally used the sh Rake method and executed sql commands in batch mode http://dev.mysql.com/doc/refman/5.5/en/batch-mode.html

sh "mysql -u root mydb_development -e 'source import_legacy_database.sql'"
