10.5 Executing SQL statements that modify information in a database
The pureQuery inline-method style provides methods named update and updateMany
for executing SQL statements that modify the information stored in database tables. These
methods can execute SQL statements that do not return query results, such as INSERT,
UPDATE, and DELETE.
The Data interface contains two update methods for executing a single SQL statement
one time, as well as three methods for updating an SQL statement multiple times.
10.5.1 Executing an SQL statement one time by using the method: int
update (String sql, Object... parameters)
The method int update (String sql, Object... parameters) executes the
specified SQL statement and returns an int indicating how many rows were updated.
Listing 10.14 shows an example of using this method.
EmployeeBean newEmployee = new EmployeeBean ();
newEmployee.setEmployeeNumber ("010010");
newEmployee.setFirstName ("FirstName");
newEmployee.setLastName ("LastName");
newEmployee.setEducationLevel (18);
int updateCount = data.update (
"INSERT INTO EMPLOYEE (EMPNO, FIRSTNME, LASTNAME, EDLEVEL)
VALUES (:employeeNumber, :firstName, :lastName, :educationLevel)",
newEmployee);
System.out.println ("Update count: " + updateCount);
