Can Multiple SQL Queries be Executed Simultaneously using MySQL Connector/J?

Executing Multiple Queries Using MySQL Connector/J

Your issue stems from the misconception that multiple SQL queries can be executed simultaneously using MySQL Connector/J, separated by semicolons. However, the purpose of semicolons in SQL is typically to terminate command line or script input, not as part of the statement syntax itself.

According to the JDBC specification, each statement prepare or execute should correspond to a single SQL statement. Therefore, multiple statements separated by semicolons are invalid and will result in syntax errors.

To execute multiple queries, you need to use separate execute calls. However, MySQL offers an optional configuration property, allowMultiQueries, that can be set to enable support for multiple executions. Note that this feature is not compliant with the JDBC specification and may reduce code portability.
