How to run sql scripts in GitHub Actions - github-actions

Question

I'm currently building application and want to test on GitHub actions.
I'm using mysql for database and need to insert test data(csv format) into GitHub action's container, but it's not working well.
Here is the steps.
Create mysql container. → OK
Run script to create table. → NG.
Insert test data into table created on step2. → NG.
In every step, there are no errors, but it seems I can't run scripts in step2 and step3.
Please tell me which part of my code is wrong.
Codes here.
