The following code examples show how to use data modification statements.

Procedure for Updates

You can use Exec to execute data modification statements. Exec returns a Result value which contains the number of affected rows.

INSERT

To insert updates:

result, _ := db.Exec("INSERT INTO Movies (MovieRating) VALUES ('R')")
affected, _ := result.RowsAffected()

UPDATE

To retrieve updates:

result, _ := db.Exec("UPDATE Movies SET MovieRating = 'R' WHERE MovieRuntime = 'R'")
affected, _ := result.RowsAffected()

DELETE

To delete updates:

result, _ := db.Exec("DELETE FROM Movies WHERE Id = '70f6284d2a395396dbb3a60b4ce3d2d6'")
affected, _ := result.RowsAffected()
