Parameterized Table Name for Data Retrieval
When attempting to utilize prepared statements to define a table name for data retrieval, users often encounter errors. This issue arises when a parameter is used in place of a required table name.
Consider the following example:
private String query1 = "SELECT plantID, edrman, plant, vaxnode FROM [?]"; // ?=date
This query attempts to use a parameter (?) to represent the table name, which is not supported. Instead, the table name must be hard-coded.
To resolve this issue, declare the table name explicitly in the query:
private String query1 = "SELECT plantID, edrman, plant, vaxnode FROM [" + reportDate + "]?"";
This modification ensures that the table name is properly specified, enabling successful execution of the query.
The above is the detailed content of How Can I Use a Parameterized Table Name in a SQL Query?. For more information, please follow other related articles on the PHP Chinese website!

Java is platform-independent because of its "write once, run everywhere" design philosophy, which relies on Java virtual machines (JVMs) and bytecode. 1) Java code is compiled into bytecode, interpreted by the JVM or compiled on the fly locally. 2) Pay attention to library dependencies, performance differences and environment configuration. 3) Using standard libraries, cross-platform testing and version management is the best practice to ensure platform independence.

To set up the JVM, you need to follow the following steps: 1) Download and install the JDK, 2) Set environment variables, 3) Verify the installation, 4) Set the IDE, 5) Test the runner program. Setting up a JVM is not just about making it work, it also involves optimizing memory allocation, garbage collection, performance tuning, and error handling to ensure optimal operation.
