Not Creating Table with PDO - php

Question

I have a sql command that I am trying to execute using PDO and it executes true, but the table is not created. I have no idea what I am doing wrong. I looked around the internet to see if anyone else has had this problem, but I didnt really seem to find anything that fixes it. Here is the SQL Command
CREATE TABLE table_230
(
id VARCHAR(255),
cost VARCHAR(255),
title VARCHAR(255) NOT NULL,
package_quantity VARCHAR(255) NOT NULL,
package_cost VARCHAR(255) NOT NULL,
asin VARCHAR(15) NOT NULL,
rank VARCHAR(20) NOT NULL,
category VARCHAR(255) NOT NULL,
bb_price VARCHAR(255) NOT NULL,
seller_type VARCHAR(255) NOT NULL,
size_tier VARCHAR(255) NOT NULL,
amazon_fee VARCHAR(255) NOT NULL,
roi VARCHAR(255) NOT NULL,
parent_asin VARCHAR(255) NOT NULL,
complete TINYINT(1) DEFAULT 0
)
The command runs in PHPMyAdmin when I attempt to execute it, but it does not work when I use PDO. The code that I use looks like this:
$create = $this->dbConnection->prepare("
CREATE TABLE IF NOT EXISTS table_" . $tableId ."
(
id VARCHAR(255),
cost VARCHAR(255),
title VARCHAR(255) NOT NULL,
package_quantity VARCHAR(255) NOT NULL,
package_cost VARCHAR(255) NOT NULL,
asin VARCHAR(15) NOT NULL,
rank VARCHAR(20) NOT NULL,
category VARCHAR(255) NOT NULL,
bb_price VARCHAR(255) NOT NULL,
seller_type VARCHAR(255) NOT NULL,
size_tier VARCHAR(255) NOT NULL,
amazon_fee VARCHAR(255) NOT NULL,
roi VARCHAR(255) NOT NULL,
parent_asin VARCHAR(255) NOT NULL,
complete TINYINT(1) DEFAULT 0
)");
if($create->execute() === true)
{
return true;
}
It always returns true. If someone could help me out, I would really appreciate it!

Set up your connection first:
$mysql_host = "servername";
$mysql_database = "dbname";
$mysql_user = "username";
$mysql_password = "pass";
try{
$conn = new PDO(
"mysql:dbname=" . $mysql_database .
";host=" . $mysql_host .
";charset=utf8" ,
$mysql_user ,
$mysql_password ,
array( //
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"
)
);
}catch(PDOException $e){
echo $e->getCode();
}
Then query:
$tableId=$conn->lastInsertId();
$create = $conn->prepare("
CREATE TABLE IF NOT EXISTS table_" . $tableId ."
(
id VARCHAR(255),
cost VARCHAR(255),
title VARCHAR(255) NOT NULL,
package_quantity VARCHAR(255) NOT NULL,
package_cost VARCHAR(255) NOT NULL,
asin VARCHAR(15) NOT NULL,
rank VARCHAR(20) NOT NULL,
category VARCHAR(255) NOT NULL,
bb_price VARCHAR(255) NOT NULL,
seller_type VARCHAR(255) NOT NULL,
size_tier VARCHAR(255) NOT NULL,
amazon_fee VARCHAR(255) NOT NULL,
roi VARCHAR(255) NOT NULL,
parent_asin VARCHAR(255) NOT NULL,
complete TINYINT(1) DEFAULT 0
)");
if($create->execute() === true)
{
return true;
}
This code works. Are you sure your $tableId variable is having expected value? you should var_dump($tableId) to see what's in it!
