I am trying to create an ecommerce application using laravel, So when someone orders something, I store data in orders table, in which a column "products" exists.
I store json object in this column.
this is products json:
[{"pid":65,"min_price":"349.0000"},{"pid":71,"min_price":"349.0000"}]
Now, I want to show these order details to the user profile. So, i need to fetch rows from an another table (products), with the primary key same as "pid" in given json object.
please, suggest me how to resolve it.
You can't do this without retrieving it first and looping over it or something.
What you might want to consider is the following:
Remove the column products from the orders table and create a order_product table. This is called a pivot table.
You can create this table by running the command php artisan create:migration CreateOrderProductTable
Now in this table you define 2 foreign keys. order_id and product_id.
If you have done this, you have to create the relations in the Product model and the Order model.
You can now use this relation to query all products that an order has like this: Order::find(1)->products()->get()
I have a table cars with attributes: id, name. I also have another table specs with id, car_id, name. This tables are related with one to many relations from the Models. I also have set up the foreign keys in.
I have a controller manageData where i have a function insertCar which i use to insert data and update both tables. I wan to create another function deleteCar from where i can delete the car along with its specs from the other table
Use onDelete() method in migration when defining foreign key:
$table->foreign('car_id')->references('id')->on('cars')->onDelete('cascade');
In this case when you'll delete a car record, related data will be automatically deleted from another table.

I am trying to load the tables into oracle in-memory database. I have enable the tables for INMEMORY by using sql+ command ALTER TABLE table_name INMEMORY.

What can be the problem?

Population of the IM Column Store in Response to Queries
Setting the INMEMORY attribute on an object means that this object is a candidate for population in the IM column store, not that the database immediately populates the object in memory.
By default (INMEMORY PRIORITY is set to NONE), the database delays population of a table in the IM column store until the database considers it useful. When the INMEMORY attribute is set for an object, the database may choose not to materialize all columns when the database determines that the memory is better used elsewhere. Also, the IM column store may populate a subset of columns from a table.
You probably need to run a select against the date first
I got two schema A and B. In A there is a table 'company' and in B there is a table 'newcompany'. Now I need all the data which is residing on A.company to be updated on B.newcompany whenever there is some data updation on A.company.
Please help me out with a query or some function which implements this functionality.
You could give grants to the user and simply access the table as B.newcompany inside an onupdate trigger for the A.company table.
