Question

I am trying to use a variable to insert into multiple tables. When I hard code the specific table name it runs properly, when I use a variable I get a QUERY FAILEDSQLSTATE[42000]: Syntax error or access violation: 1064 error. dbname is the variable. I am using a for loop to change the name of the table. For example table 1 is budget1000, then budget 2000 etc. Here is my code

$sql='INSERT INTO ".$dbName." VALUES(:id,:category,:subCategory,
:amount, :today,:description,   :year)';


try{
$st= $conn->prepare($sql);
$st->bindValue(":id", $id, PDO::PARAM_INT);
$st->bindValue(":category", $category, PDO::PARAM_INT);
$st->bindValue(":subCategory", $subCategory, PDO::PARAM_INT);
$st->bindValue(":amount", $amount, PDO::PARAM_INT);
$st->bindValue(":today", $today, PDO::PARAM_STR);
$st->bindValue(":description", $description, PDO::PARAM_STR);
$st->bindValue(":year", $year, PDO::PARAM_INT); 
$st->execute();
}catch(PDOException $e ){
echo "QUERY FAILED" . $e->getMessage();

}

Try this instead:

$sql='INSERT INTO '.$dbName.' VALUES(:id,:category,:subCategory,:amount, :today,:description,   :year)';
