How does MySQL execute multiple SQL statements at the same time?

This problem was discovered when we made a database initialization tool, that is, when executing an SQL Statement in a Statement, it can be correctly executed. If multiple statements are executed at the same time

This problem was found during database initialization tools, that is, when an SQL Statement is executed in a Statement, it can be correctly executed. If Multiple SQL statements are executed at the same time, an SQL syntax error will be reported, it hurts your mind.

You can find two solutions on the Internet:

1. The simplest way is to set the allowMultiQueries parameter to true in the MySQL connection string.

2. Split the SQL Statement into multiple SQL statements using a semicolon in the program, use the addBatch method of Statement, and finally exectebatch.

Conclusion: The first method is the simplest.

I hope this will be helpful to my friends who will encounter such problems in the future.

Note: JDBC batch processing cannot be added to select statements; otherwise, an exception is thrown:

Java. SQL. BatchUpdateException: Can not issue SELECT via executeUpdate ().
