[Lazarus] Postgres database again...

[Dave Coventry]

Damien this is the code I'm using:

      sqlq:='INSERT INTO registration
(enquiryreferencenumber,fname,sname,initials,id,titlecombobox,postaladdy,town,country,pcode,cell,email,emailtld,enquirydate)
';
      sqlq:=sqlq+'VALUES
(nextval(''reg_seq''),'''+FName.Text+''','''+SName.Text+''','''+Initials.Text+''','''+ID.Text+''','''+TitleComboBox.Text+''','''+PostalAddy.Text+''','''+Town.Text+''','''+Country.Text+''','''+PCode.Text+''','''+Cell.Text+''','''+email.Text+''','''+emailTLD.Text+''','''+EnquiryDate.Text+''')';
      PQConnection1.Connected:=True;
      PQConnection1.ExecuteDirect('Begin Work;');
      PQConnection1.ExecuteDirect(sqlq);
      PQConnection1.ExecuteDirect('Commit Work;');
      PQConnection1.Connected:=False;
      SQLQuery1.SQL.Clear;
      SQLQUery1.SQL.Append('SELECT enquiryreferencenumber FROM
registration WHERE fname = '''+FName.Text+''' AND sname = '''+
Sname.Text+''';');
      SQLQuery1.Open;
      enquiryreferencenumber.Text:=SQLQuery1.Fields[0].AsString;
      SQLQuery1.Close;

The error I get is because SQLQuery1.Fields[0]. is out of range, so
there is nothing in SQLQuery1.Fields.

(I'm also, rather clumsily trying to access the last record using the
fname and sname; I would prefer to have a more reiable way of
retrieving it)
