Modifying Data
The following code examples show how to use data modification statements.
Procedure for Updates
You can use odbc_exec to execute data modification statements. This will return a resource which contains the number of affected rows.INSERT
To insert updates:
$result = odbc_exec($cnx, "INSERT INTO Tweets(Text) VALUES ('My twitter message 2')"); $affected = odbc_num_rows($result);
UPDATE
To retrieve updates:
$result = odbc_exec($cnx, "UPDATE Tweets SET Text = 'My twitter message 2' WHERE From_User_Name = 'twitter'"); $affected = odbc_num_rows($result);
DELETE
To delete updates:
$result = odbc_exec($cnx, "DELETE FROM Tweets WHERE Id = '123456789'"); $affected = odbc_num_rows($result);
