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 [HarperDB].[cstest].Cutomers(CompanyName) VALUES ('RSSBus Inc.')"); $affected = odbc_num_rows($result);
UPDATE
To retrieve updates:
$result = odbc_exec($cnx, "UPDATE [HarperDB].[cstest].Cutomers SET CompanyName = 'RSSBus Inc.' WHERE Country = 'US'"); $affected = odbc_num_rows($result);
DELETE
To delete updates:
$result = odbc_exec($cnx, "DELETE FROM [HarperDB].[cstest].Cutomers WHERE _id = '22'"); $affected = odbc_num_rows($result);
