To use rowupdating validating xml through xsd
are iterated over and each parameter variable in the update statement is replaced with the value for that parameter. Event Args e) private void da_Row Updating(object sender, Sql Row Updating Event Args e) object.
Single quote delimiters are added around the string values. The solution delimits the string values for the Category Name and Description fields in the Categories table from the Northwind database used in this example.
The code looks like this: As shown previously on this blog, there is a significant cost of JDBC server roundtrips, which can be seen in the JDBC benchmark.
This cost is much more severe if we unnecessarily create many server roundtrips for a task that could be done in a single roundtrip, namely by using a SQL bulk .
What happens with this is that the source is being created every time the user submits the page.
This means that when the user does an update, the data from that update is lost.
If you are using command buttons, then do not use Auto Generate Edit Button.
Something that has been said many times, but needs constant repeating until every developer is aware of its importance, is the performance difference between row-by-row updating and bulk updating. Let me ask this differently: The best way to find out is to benchmark.
-Frinny Hi all, I seem to be having the same issue but I don't quite follow the trouble with the above post. Can you explain the T/S a little more or maybe point me to another post that may have already covered it? Hi all, I seem to be having the same issue but I don't quite follow the trouble with the above post. Can you explain the T/S a little more or maybe point me to another post that may have already covered it? It's quite common that people create the data source and bind this source to the Grid View in their Page_Load() method.
If doing everything in a single statement isn't possible due to the limitations of SQL, we can still save roundtrips by grouping statements in a block, either by using an anonymous block in databases that support them: (You can easily send these anonymous blocks over JDBC, as well!
) Or, by emulating anonymous blocks using the JDBC batch API (has its limitations), or by writing stored procedures.
NET Forum so that other people can learn from the experience too. -Frinny You may need to turn off validation even if you are not validating anything.
It seems like the Java Script can get mangled otherwise.
