Can I know which forum to post to cos I think this may be the wrong forum. Cos it is sql so this forum maybe for sql execute inside the database. However, I read there is no more jdbc forum, correct me if I am wrong.

Hi,
This is a continuation of my last problem - not sure if I should write from there cos the first part was solved with the help from this group.
I was trying to get the matching tutor_id with the parameter values which is in this case subject_names from a table which contains both the tutor_id and the subject_names.
Here's the error message:
org.postgresql.util.PSQLException: ERROR: operator does not exist: text = integer
Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts.

at Controller.searchController.doPost(searchController.java:108)
Here's the code snippet which I do not know where I had gone wrong:
String sql1 = "select tutor_id, subject_name from tutor_subject where subject_name in ("
+ builder.deleteCharAt(builder.length() - 1).toString() + ")";
PreparedStatement ps2 = connection.prepareStatement(sql1);
HashMap<Integer, ArrayList<String>> tutorSubject = new HashMap<Integer, ArrayList<String>>();
for(String item : subjs) {
int tutor_id = tutor.getTutor_id();
ps2.setInt(1, tutor_id);
if (item != null) {
subjs.add(item);
ps2.setString(2, item);
}
ps2.executeQuery();
while (rs.next()) {
tutor_id = rs.getInt("tutor_id");
subjs.add(rs.getString("subject_name"));
tutorSubject.put(tutor_id, subjs);
System.out.println(tutorSubject);
}
System.out.println("tutor ID=" + rs.getInt("tutor_id") + ", subjectName=" + rs.getString("subject_name"));
Hope someone could point out my mistake.
Thanks.

May I know why did you say I am comparing subject_name to an integer ?
I am trying to get both tutor_id and subject_name from the same table based on the no of ? in subjectName as per parameterValues.
Again, you need to send messages to the mailing, not me personally.
That said you might want to first figure out what:
ps2.setInt(1, tutor_id);
is supposed to accomplish in your code.
