Hi,
I am trying to limit LEFT JOIN to select only one record. By design the child table should have only one record but I ran into a case where user had two records (wrong but it happens). And when two records are selected the entire resulting query is wrong. So, for example, say I have the following query:
select .... from Table1 left join Table2 on Table1.pk_field = Table2.pk_field
How can I change (if possible) the ON expression so that if Table2 has more than one record that matches the Table1.pk_field, only one is selected? (It does not matter to me which one). TIA.
