I am using Vercel's database and so their SDKs.
I have two tables to run the same queries against, depending on the input value.

so I thought I could write a query like this:

function getData(inputValue: number) {
  const tableName = number > 10  ?  'tableA' : 'tableB';
  const data = sql<MyDataDefinition>`
    SELECT *
    FROM ${tableName}
    WHERE 1=1
  `;
  return data.rows;
}

But it failed, with an error NeonDbError: syntax error at or near "$1" . If I replace the $tableName variable with one of the table names, it would run.

Anybody know how to properly pass table name as a variable? Thanks.
