The code you write, SSMS are not given you wrong? Is completely blind to,
There are no mistakes in addition to the first line of the begin, everything else is wrong.

Write the correct grammar to ask again

Forgot to say, this is a stored procedure, I written in monitoring cat MYSQL function function, version 10.7

It took me a few days temporary self-taught... Before learn SQL, not only learned some process oriented programming language, I don't know written in SQL process oriented, more do not know how to object-oriented, so how can you tell me where the grammar is wrong?

In addition, SSMS did not report errors
