mysql jdbc-driveren understøtter ikke afgrænsere i triggere med flere sætninger

Delimiter er en kommando til SQL-klient. Der er ingen grund til at bruge skilletegn i JDBC. Eksemplet nedenfor viser det:

import java.sql.*;

public class TriggerExample {

    public static void main(String args[]) {

        String connectionURL = "jdbc:mysql://localhost:3306/test";
        Connection con = null;

        try {
            Class.forName("com.mysql.jdbc.Driver");
            con = DriverManager.getConnection(connectionURL, "login",
                    "password");
            Statement stmt = con.createStatement();
            stmt.execute("CREATE TRIGGER obs_update BEFORE UPDATE ON obs "
                    + "FOR EACH ROW "
                    + "BEGIN "
                    + "IF OLD.voided = 0 AND NEW.voided = 1 THEN "
                    + "   DELETE FROM clinic_obs WHERE id = OLD.obs_id; "
                    + "ELSE "
                    + "   UPDATE clinic_obs SET clinic_obs.revision_token = NOW() "
                    + "   WHERE NEW.id = clinic_obs.id; "
                    + "END IF; "
                    + "END;");
            con.close();
        } catch (SQLException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (con != null) {
                try {
                    con.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
