Updating database using dataadapter Webcam show for free no money are credit card needed


Dim str SQL As String Dim sql Cmd As Sql Command Dim sql Conn As Sql Connection str SQL = "INSERT INTO My Table (Col1, Col2) VALUES........." sql Conn = New Sql Connection("........") sql Cmd = New Sql Command(str SQL, sql Conn) sql Conn. The same row can also be inserted using Sql Data Adapter like this: Dim d Set As Data Set Dim d Row As Data Row Dim d Table As Data Table Dim sql Cmd As Sql Command Dim sql Conn As Sql Connection Dim sql Dapter As Sql Data Adapter sql Conn = New Sql Connection("..........") sql Dapter = New Sql Data Adapter sql Cmd = New Sql Command("SELECT * FROM My Table", sql Conn) sql Dapter. Since this post comes up among the first ones on google when looking for "sqldataadapter/insert/data", I wanted to reply to it.

Close() But if the Sql Data Adapter object is used to insert/update/delete records in the data source, is it ALWAYS necessary to first make the necessary changes in the Data Set for the data source to reflect the changes? The code I have shown in my first post (which doesn't use Sql Data Adapter) inserts a row in the data source....correct? If you want to update your Data Source without that line you have commnted then try to fill again your Data Set with the Updated values from the Data Base...

So is it ALWAYS necessary to first make the changes in the Data Table for the data source to reflect the change when Sql Data Adapter is used? what i mean is that you can INSERT data to your database without using sql Data Adapter like using System. As I said in my previous post, if the blue lines in the code in that post are commented, then the INSERT SQL statement doesn't insert a new row in the data source. Well im not really sure about that because im not doing that before..When an application calls the Update method, the Data Adapter examines the Row State property, and executes the required INSERT, UPDATE, or DELETE statements iteratively for each row, based on the order of the indexes configured in the Data Set.I'm sure there is an extremely simple reason that this one line isn't working, but it has evaded for the past week, so I'm hoping someone else will notice my fault. Tables("My Table") sql Cmd = New Sql Command("INSERT INTO My Table (Col1, Col2) VALUES (@Val1, @Val2)", sql Conn) With sql Cmd . It might also mean a high risk for a Data Integrity bug like in this example where the data is set directly. So if you would try to omit that line the changes doesn't reflect in your datasource as what you have noticed..If the connection is closed before Fill is called, it is opened to retrieve data, then closed.
