A Browse form containing a JOIN

[absalom]

Hi, as soon as I add a JOIN clause in my SQL request (browse FORM), it stops working (no record is returned); if I remove the clause (and the relevant fields to be displayed) I get the expected rows.

How can I handle this clause?

Can you post your SQL?

[absalom]

My SQL is:

Code: Select all

SELECT consultations.date, patients.nom, patients.prenom, consultations.type, consultations.prix, consultations.type_reglement
  FROM consultations JOIN patients ON consultations.id_patient = patients.id
  WHERE consultations.date_encaissement IS NULL
ORDER BY consultations.date DESC

Result is as expected on phpMyAdmin

Make sure that the column names in the column Display are written exactly as in the SELECT statement.

If you press CTRL+SHIFT+I (Options Menu -> Form Info) you will see the generated SQL.

Both tables have 'id' as their primary key fields, and the generated SQL tries to select the ambiguous field 'id'.

Do I have to change the name of my column in the database and fix the change everywhere in NuBuilder, or can I still do it as it?

Finally did it by creating a view with the JOIN instead

Could could try a SELECT ... FROM ... SELECT:

Code: Select all

SELECT date, nom, prenom, type, prix, type_reglement FROM (
SELECT consultations.id, consultations.date, patients.nom, patients.prenom, consultations.type, consultations.prix, consultations.type_reglement
  FROM consultations JOIN patients ON consultations.id_patient = patients.id
  WHERE consultations.date_encaissement IS NULL
) T
ORDER BY consultations.date DESC
