create multiple views with a mysql stored procedure - mysql

Question

I wanted to build around 900 views(1 view for 1 table and based on 2 conditions) and i have all the table names in a table in mysql environment. I have created a stored proc . For test purpose i used limit 1.
I get below error when i call the sp.
Actually I re-wrote a mssql sp, did i miss anything here. please help
