Hello folkz,
Is it possible to setup in dovecot-sql.conf file to run user_query
twice if its first run didn't yield any values.
And likewise don't proceed with the second run if the first user_query
execution produced the result.
I have to query two tables which specify there email messages shall be
delivered via Dovecot deliver LDA
depending on the incoming email addresses.
Please don't question me about this setup. I inherited this mess from
the previous Network Admin.
First query should be ran like this:
user_query = SELECT concat('maildir:/data/mail/',maildir) as mail FROM
folders WHERE email = '%u'
If the first query doesn't yield any result the second shall be ran like
this:
user_query = SELECT maildir as home FROM users WHERE email = '%u'
Please advise if such user_query setup is possible at all.
Thanks in advance,
Alex

Most employers want reliability and stability, if they are the obstacle, explain to them the nightmare it is now and how easy it is to uniform everything, if you do it right, they'll likely remember that when it comes to future contract/salary/wage negotiations.

yes, something akin to this (assuming they are in the same schema) . sorry i cannot be more helpful with the query. the secret is the chance to retrieve multiple results, but limiting those results to one row and having them priroritized mail > users user_query = select mail from (select mail from table where email = ? union select home as mail from users where email = ?) limit 1 On Mon, May 3, 2010 at 6:00 PM, Alex <dovecot at mailswamp.com> wrote:> Hello folkz, > Is it possible to setup in dovecot-sql.conf ?file to run user_query > twice if its first run didn't yield any values. > And likewise don't proceed with the second run if the first user_query > execution produced the result. > I have to query two tables which specify there email messages shall be > delivered via Dovecot deliver LDA > depending on the incoming email addresses. > > Please don't question me about this setup.
