Batch script to issue commands to mySQL db?

Question

I am trying to create a batch script that would connect to a mySQL database and issue a delete command:

@echo off
echo Resetting all assessments...
mysql -hlocalhost -urdfdev -p%1 rdf_feedback
delete from competency_question_answer;

I will run this script providing the password as a command-line argument, but all this script does is, connects to the database, and the mysql> prompt will be shown. After I exit from mysql, the rest of the batch commands get to execute (and fail, no surprise).

How can I pass the SQL commands from the batch script to the mysql console? Is this even possible?

Answer 1

You need to use command line tools. I don't know if there exists any for MySQL but for SQL there is SQLCMD and for Oracle there is OSQL.

What you can also do is something like this.

mysql -uuser -ppass < foo.sql

Where foo.sql is the commands you want to execute.

Answer 2

You may need to connect multiple times:

@echo off
echo Resetting all assessments...
mysql -hlocalhost -urdfdev -p%1 rdf_feedback -e delete from competency_question_answer;

Alternatively, you should be able to put all your commands in a separate file such as input.sql and use:

mysql -hlocalhost -urdfdev -p%1 rdf_feedback <input.sql
