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 Test_xlsx_Sheet1 (Column1) VALUES ('John')"); $affected = odbc_num_rows($result);
UPDATE
To retrieve updates:
$result = odbc_exec($cnx, "UPDATE Test_xlsx_Sheet1 SET Column1 = 'John' WHERE Column2 = 'Bob'"); $affected = odbc_num_rows($result);
DELETE
To delete updates:
$result = odbc_exec($cnx, "DELETE FROM Test_xlsx_Sheet1 WHERE Id = '6'"); $affected = odbc_num_rows($result);
