Hi,

I am building a inventory management system(Winforms C#), it contains billing. Data base has table "item" having fields such as item name, units, base price, Quantity and so on.

While bill generation i am adding items to it, containing similar fields as above. After bill generation i need to decrement the value of quantity field for items in database, that decrement value should be equal to the quantity of items added to bill generation. (This regarding stock management in inventory management)

Please help me to do this one and provide me coding samples.

Thanks in Advance

You need to do some research. You can start by research how to get data from a database and then how to update it. Try these articles.[^]. When you have a more specific question please post a new question with detailed information about your problem, any error messages you are getting, and even a snippet of the code you are having trouble with.

Solution 3

Make a query and get the recordset that holds the field you have to increment/decrement, the change the field by assigning it its incremented/decremented value, and finally commit the changes to the recordset...
