Why Can't I Use Prepared Statements to Set Table Names in SQL Queries?

Setting Table Names Using Prepared Statements

When working with prepared statements, it's essential to understand their limitations. In the given example, the developer encountered an error while attempting to set a table name using parameter substitution.

Issue:

The query requires a table name as the source for data retrieval, but the "SELECT" statement used a parameter where a table name was expected.

Resolution:

Table names cannot be set dynamically using prepared statement parameters. Instead, they must be hardcoded within the query itself. The solution provided changes the code to explicitly include the table name as a string within the query:

By combining the hardcoded table name with the parameter (?), the query can dynamically update the date component while preserving the reference to the correct table.
