Why Does Using Parameters for Table Names in Prepared Statements Cause Errors?

Prepared Statements and Table Names: A Common Pitfall

Using prepared statements to dynamically specify table names often leads to errors like "Parameter 'Pa_RaM000' specified where a table name is required." This error highlights a crucial limitation: prepared statement parameters cannot replace table names directly within SQL queries.

The solution is to construct the SQL query string by concatenating the table name (which must be hardcoded) with any parameterized values. Consider this corrected example:

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

Here, reportDate (a parameter) is concatenated with a fixed table name prefix. This ensures the query correctly identifies the target table. Remember that directly substituting table names with parameters is not supported by database systems using prepared statements.
