Can You Execute Multiple SQL Queries with MySQL Connector/J?

Executing Multiple Queries with MySQL Connector/J: Is It Possible?

The challenge lies in executing multiple SQL queries separated by semicolons using MySQL Connector/J. However, attempts to do so encounter a syntax error, leading to the question of whether it's feasible.

JDBC Syntax Restrictions

JDBC requires that each prepare or execute statement contain a single SQL statement. Therefore, including multiple statements in a single execution is prohibited.

Database Syntax Considerations

Additionally, certain databases, including MySQL, do not include semicolons as part of statement syntax. Hence, having one in the query results in a syntax error.

Alternative Approach

To execute multiple queries, you must use separate executions. MySQL, however, provides an optional configuration property called allowMultiQueries. When enabled, it allows multiple queries within a single execution. However, this behavior deviates from the JDBC specification and reduces code portability. Therefore, it's advisable to handle multiple queries with separate executions.
