The Procedure contains syntax error. Please help me in finding the error. The mySQL Workbench says that this has 8 errors and this cannot be applied to the database. I have already posted this question. People told me to change the CASE statement to IF.Even after changes, the error persists. I don't know how to nest this post under the original question. The actual post was posted in this link . Revised syntax is posted as requested @Caius Jard

您需要引用以数字开头的标识符:
INSERT INTO Amount(Cust_id,Book_id,Can,`300ml`,`500ml`,`1lit`,`2lit`) ...
