Updating dataset asp net
Should I make a new tutorial on this site with this samples?This post has been edited by poptcat: 05 August 2011 - PM I'm still confuse with this code since you don't have create the "Delete" table in your database. Pls tell me how your Windows Form look like using this code? Hi, Nice explanation and easy enough to understand.The following section will show you how to test updating, inserting, and deleting the data.In Lesson 3, we discussed a fully connected mode of operation for interacting with a data source by using the Sql Command object.
But if you want one test run to build on the changes from a previous test run…well, you're out of luck.
But I am facing a problem for update statements for this code. Update() is not working when i want to update contents of a row. Update(dataset, "Student") returns 0 ; Also I have tried populating student Id in the dataset along with the student Name yet the changes werent reflected.
I filled the data Grid View as select *,' Update' as [Update] from table_name ; I created a very small test table Student.
When a database receives a SQL statement, it determines if the statement has already been executed and stored in memory.
If the statement does exist in memory, Oracle Database can reuse it and skip the task of parsing and optimizing the statement.
