Prepared Statement Parameter Issue with Table Name
In an attempt to dynamically set a table name for data retrieval, an error is encountered within the prepared statement execution. The reason for this error originates from the usage of a parameter where a table name is expected.
The provided sample code employs a prepared statement with a parameter placeholder "?" and attempts to assign a value to it, representing a table name. However, this is not permissible as table names cannot be specified dynamically through parameters. They must be explicitly defined within the query itself.
Resolution
To resolve this issue, hardcode the table name directly into the query string, as demonstrated below:
This modification ensures that the table name is correctly defined within the query and can be successfully executed without the aforementioned error.
The above is the detailed content of Why Can't I Use Prepared Statement Parameters for Table Names in SQL?. For more information, please follow other related articles on the PHP Chinese website!

The core features of Java include platform independence, object-oriented design and a rich standard library. 1) Object-oriented design makes the code more flexible and maintainable through polymorphic features. 2) The garbage collection mechanism liberates the memory management burden of developers, but it needs to be optimized to avoid performance problems. 3) The standard library provides powerful tools from collections to networks, but data structures should be selected carefully to keep the code concise.

Java is widely used in enterprise-level applications because of its platform independence. 1) Platform independence is implemented through Java virtual machine (JVM), so that the code can run on any platform that supports Java. 2) It simplifies cross-platform deployment and development processes, providing greater flexibility and scalability. 3) However, it is necessary to pay attention to performance differences and third-party library compatibility and adopt best practices such as using pure Java code and cross-platform testing.
