Cannot update data in oracle database using java

Question

I'm trying to update the data from my oracle database using this code. The program has no error but it display ORA-00933: SQL command not properly ended .
Can anyone let me know what does it mean and how can I correct it?

String gdta="
  UPDATE CLIENT_DATA SET CLIENT_ADDRESS4 = 'SELANGOR' 
    WHERE CLIENT_ADDRESS4 = 68100 BATU CAVES SELANGOR D.E. 
UNION 
  UPDATE CLIENT_DATA SET CLIENT_ADDRESS4 = 'SELANGOR' 
    WHERE CLIENT_ADDRESS4 = 47100 PUCHONG,SELANGORUNION 
  UPDATE CLIENT_DATA SET CLIENT_ADDRESS4 = 'SELANGOR'
    WHERE CLIENT_ADDRESS4 = 47100 PUCHONG";

Answer 1

You can't combine update statements in a union statement. Also it looks like you need to quote the client_address4 values.

Try running your SQL command in a SQL client before trying it in java and see if it works.

I think you need to execute multiple statements, instead of a single one, like this:

String gdta="UPDATE CLIENT_DATA SET CLIENT_ADDRESS4 = 'SELANGOR' WHERE CLIENT_ADDRESS4 = '68100 BATU CAVES SELANGOR D.E.'";
String gdta2="UPDATE CLIENT_DATA SET CLIENT_ADDRESS4 = 'SELANGOR' WHERE CLIENT_ADDRESS4 = '47100 PUCHONG,SELANGOR'";
String gdta3="UPDATE CLIENT_DATA SET CLIENT_ADDRESS4 = 'SELANGOR' WHERE CLIENT_ADDRESS4 = '47100 PUCHONG'";

or, use a single statement with an in-clause:

String gdta="UPDATE CLIENT_DATA SET CLIENT_ADDRESS4 = 'SELANGOR' WHERE CLIENT_ADDRESS4 in ('68100 BATU CAVES SELANGOR D.E.', '47100 PUCHONG,SELANGOR', '47100 PUCHONG')";
