Java.sql.SQLIntegrityConstraintViolationException: 無效的呼叫引數 - 解決方法

This exception is thrown when there is an invalid call to a database statement or query. It indicates that there is a violation of the integrity constraints defined on the database tables.\n\nThe most common cause of this exception is when trying to insert or update data into a table, and the values being provided do not match the constraints defined on the table. This can include violations such as inserting a null value into a column that does not allow nulls, inserting a duplicate value into a column with a unique constraint, or violating a foreign key constraint.\n\nAnother possible cause is passing invalid arguments to a method or function that interacts with the database. This could be due to passing null values or incorrect data types that do not match the expected parameters.\n\nTo fix this issue, you should review the integrity constraints defined on the database tables and ensure that the data being inserted or updated adheres to these constraints. Additionally, check the arguments being passed to the database methods or functions to ensure they are valid and match the expected data types.
