I am using the JdbcTemplate. What i want to do is insert a record into the database however the primary key for the table is set to auto increment so i wont have to insert a value, how can i retrieve the id once i complete the insert?. Is there a simple way to do this or do i need to do another query to select it?
Example Of Jdbc Insert
Here the citizenId is autogenerated
public void saveCitizen(Citizens citizen) {
logger.debug("In saveCitizens");
int count = getJdbcTemplate().update("INSERT INTO crimetrack.tblcitizens (citizenId,fName,lName,oName,photo,countryId,addLn1, addLn2, addLn3,"
+"genderId,ethnicityId, skinColorId, eyeColorId,hairColorId,occupationId,"
+"phoneNo, maritalStatusId, noticableFeatures,weight,height,citizenTypeId,dob)"
+ "VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)"
, new Object[]{citizen.getfName(),citizen.getlName(),citizen.getoName(),
citizen.getPhoto(),citizen.getCountryId(),citizen.getAddLn1(),
citizen.getAddLn2(),citizen.getAddLn3(),citizen.getGenderId(),
citizen.getEthnicityId(),citizen.getSkinColorId(),citizen.getEyeColorId(),
citizen.getHairColorId(),citizen.getOccupationId(),citizen.getPhoneNo(),
citizen.getMaritalStatusId(),citizen.getNoticeableFeatures(),
citizen.getWeight(),citizen.getHeight(),citizen.getCitizenTypeId(),
citizen.getDob()});
logger.info(count +" Rows affected in tblCitizens");
See 12.2.8: Retrieving auto generated keys:
http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/jdbc.html
just give you the example code, in case that link is broken. See it:
final String INSERT_SQL = "insert into my_test (name) values(?)";
final String name = "Rob";
KeyHolder keyHolder = new GeneratedKeyHolder();
jdbcTemplate.update(
new PreparedStatementCreator() {
public PreparedStatement createPreparedStatement(Connection connection) throws SQLException {
PreparedStatement ps =
connection.prepareStatement(INSERT_SQL, new String[] {"id"});
ps.setString(1, name);
return ps;
}
},
keyHolder);
// keyHolder.getKey() now contains the generated key
