My title for this message is not very clear, I am sorry, I just could not define it in one line.
In my SQL I have the following left join:
left join &cParentAlias. on cPrefix + &cParenField. = &cChildField.
But sometimes I have no need for this left join, that is, there is no cParentAlias and the rest. How can I make this Left Join to be ignored by SQL Select?
Thank you.
