I want to know if can do this:

CREATE TABLE IF NOT EXISTS `mydb`.`store` (
`id` INT NOT NULL,
`name` VARCHAR(45) NULL,
PRIMARY KEY (`id`))
ENGINE = InnoDB

CREATE TABLE IF NOT EXISTS `mydb`.`type` (
`id` INT NOT NULL,
`description` VARCHAR(45) NULL,
PRIMARY KEY (`id`))
ENGINE = InnoDB

CREATE TABLE IF NOT EXISTS `mydb`.`product` (
`id` INT NOT NULL,
`name` VARCHAR(45) NULL,
`type` INT NULL,
`store` INT NULL,
PRIMARY KEY (`id`),
INDEX `fk_product_type_idx` (`type` ASC),
INDEX `fk_product_store_idx` (`store` ASC),
CONSTRAINT `fk_product_type`
FOREIGN KEY (`type`)
REFERENCES `mydb`.`type` (`id`)
ON DELETE NO ACTION
ON UPDATE NO ACTION,
CONSTRAINT `fk_product_store`
FOREIGN KEY (`store`)
REFERENCES `mydb`.`store` (`id`)
ON DELETE NO ACTION
ON UPDATE NO ACTION)
ENGINE = InnoDB

- Insert product, type and store in fewest lines (or one statement).
- Select product and retrieve type and store.
- Select stores by product type (i.e., How many stores have wood products?)
- Delete row(s)

Thank you in advance for your time and attention.

Currently it does not provide create table statements. What it does do is connect to a database and build classes for the following.

1. Class representing the data row for a table.
2. Class representing fields in a table row.
3. Class with public static functions that allows for executing the following queries:
A. selecting all elements in a table.
B. selecting a specific row in a table based on the primary key.
C. Updating a table row based on a primary key.
D. Insert a table row.

These classes are independent of the type of connection used to mysql databases. I had thought about building those in though as an upgrade.
Anyways, I will paste some sample code below to show you what is built.

I will put this example usage here as well.

function AddToLog($msg='',$mysqlMsg='')
{


/**
* Create the data object
*/
$Tracking_order_fileprocess_logData = new Tracking_order_fileprocess_logData();

$Tracking_order_fileprocess_logData->orderId = $orderIdNumber ;

$Tracking_order_fileprocess_logData->personalDescription = addslashes($msg) ;

$Tracking_order_fileprocess_logData->mysqlErrorDescription = addslashes($mysqlMsg) ;

/**
* Get the insert statement
*/
$insertSql = Tracking_order_fileprocess_logTableQuery::ReturnInsertSql($Tracking_order_fileprocess_logData);

/**
* Execute it with you database connection preference
* $dbConnect is a mysqli wrapper object I have written
*/
$dbConnect->executeQuery($insertSql);
