To insert, update, and delete data using a Data Adapter, you create an Ole Db Command object with INSERT, UPDATE, and DELETE statements and set the Insert Command, Update Command, and Delete Command properties of the data adapter to Ole Db Command.
Transaction services basically include beginning the transaction, executing the SQL statements that make up the transaction, and either perform a commit on overall success of each SQL statement or rollback the transaction as a whole if one of the SQL statements fails.
Transactions might need to be grouped in situations where multiple updates are needed and the entire set of transactions is to be committed or the entire set undone in case of a single failure.
The Find method returns the row with Customer Id = Tst ID.
After that I assign values of the row and call the Data Adapter's Update method. Updating data using the Data Adapter's Update method Deleting a row is simple.
For example, if you call Delete on a row on the Data Set, then when Update is called on the Data Adapter, the Delete Command of the Data Adapter will be called using the particular row in the Data Set.
Note: Keep in mind that this Update is different than a SQL UPDATE statement.
In auto-commit mode, every SQL statement is executed as a single transaction that is immediately committed to the database.
To execute multiple SQL statements as part of a single transaction, the auto-commit is to be disabled. Committing of DML INSERT, UPDATE, or DELETE statements in JDBC programs is done automatically.
User can click on Update button to Update his/her record in table.
The following line of code illustrates this: String sql = "INSERT INTO emp VALUES (? A second issue with transactions occurs when changes to the database become visible to the rest of the application system. For example, in a multi-user system, when do changes performed by one user become visible to the remaining users?
The way the architecture works with the Data Adapter is that you can make any changes you want to the filled Data Set, and it won't affect the database until you call the Update method.Tags: Adult Dating, affair dating, sex dating
