You may encounter annoying "number overflow" errors when connecting to Oracle database using IntelliJ IDEA. Such errors usually stem from data type incompatibility or configuration issues. This article will provide detailed troubleshooting steps.
Analysis of the cause of error: The error prompt shown in the picture indicates that the number is overflowing. This is usually because the Java data type does not match the Oracle database data type. For example, Oracle's NUMBER type may cause Java's long or int type overflow in some cases.
Solution:
Verify data type matching: Carefully check whether the JDBC data type used in Java code is consistent with the data type of the corresponding field in Oracle database. If Oracle databases use NUMBER type to store potentially large values, use a type that can accommodate larger values ??on the Java side, such as
BigDecimal
.Adjust the JDBC driver configuration: Try updating the Oracle JDBC driver to the latest version, or check the accuracy of the driver configuration.
Utilize ORM framework: If you use an ORM framework (such as Hibernate), make sure that the data type definition in the mapping file is correct. For manually written SQL queries, be sure to use the correct type to process the result set.
Check the database table structure: Check the design of the database table and whether there are any areas that need to be adjusted. Incorrect table structure design can also cause number overflows.
Enable logging and debugging: Enable detailed logging and debugging mode in IDEA for clearer viewing of error messages, thereby quickly locate the root cause of the problem.
Through the above method, you should be able to effectively resolve the number overflow error that occurs when IntelliJ IDEA connects to Oracle database. If the problem still exists, it is recommended to further check the code logic and database configuration to troubleshoot other potential problems.
