How Can I Correctly Use Prepared Statements When the Table Name Is Dynamic?

Using Prepared Statements Effectively for Table Name Retrieval

In attempting to execute a query using prepared statements, you may encounter an error when setting the table name as a parameter. The error typically indicates that a table name is expected instead of a parameter.

To resolve this issue, it's crucial to understand that table names cannot be specified as parameters in a prepared statement. They must be hard-coded into the query.

Revised Query

Therefore, to correctly select data from a table based on a date parameter, you should modify your query as follows:

private String query1 = "SELECT plantID, edrman, plant, vaxnode FROM [" + reportDate + "?]";

In this revised query, reportDate is appended to the hard-coded table name, ensuring that the table name matches the desired date range.

By adhering to this convention, you will successfully execute prepared statement queries that involve table names as part of the selection criteria.
