I'm thinking the coffee isn't strong enough today. I need to query the table fb-celebotd to get the photoid that matches the fb-celebotd.celebdate. Most of the other info needed is dependent on the photos table.
The following is giving me a mysql error:
Select photos.*,photographer.name, events.eventname, events.eventhome, subevents.subeventname, photodir.photodir, fb-celebotd.celebdate, fb-celebotd.trivia
from photos
LEFT JOIN fb-celebotd ON (photos.photoid = fb-celebotd.photoid)
LEFT JOIN photodir ON (photos.photodirid = photodir.photodirid)
LEFT JOIN photographer ON (photos.photographerid = photographer.photographerid)
LEFT JOIN events ON (photos.eventid = events.eventid)
LEFT JOIN subevents ON (photos.subeventid = subevents.subeventid)
WHERE fb-celebotd.celebdate=1277092800
Is this doable in one query or do I have to query fb-celebotd for the photoid and trivia first and then query other tables based on the photoid?
Thanks.
Should fb-celebotd (with a dash) be fb_celebotd (with an underscore)? If the table name has a dash, then you'll have to quote the table name: "fb-celebotd". Otherwise the dash is treated as a minus sign and tries to subtract celebotd from fb (both unknown).
If you really have a table named fb-celebotd, then you need to quote the table name every time you use it in a query:
Select photos.*,photographer.name, events.eventname, events.eventhome, subevents.subeventname, photodir.photodir, `fb-celebotd`.celebdate, `fb-celebotd`.trivia
from photos
LEFT JOIN `fb-celebotd` ON (photos.photoid = `fb-celebotd`.photoid)
LEFT JOIN photodir ON (photos.photodirid = photodir.photodirid)
LEFT JOIN photographer ON (photos.photographerid = photographer.photographerid)
LEFT JOIN events ON (photos.eventid = events.eventid)
LEFT JOIN subevents ON (photos.subeventid = subevents.subeventid)
WHERE `fb-celebotd`.celebdate=1277092800

I have created a MySQL view to grab data from four differents tables :
CREATE VIEW `documents_scannes_view` AS
select `ds`.`id_document` AS `id_document`,
`ba`.`num_boite` AS `num_boite`,
`ds`.`annee` AS `annee`,
`ds`.`ref_document` AS `ref_document`,
`ds`.`num_client` AS `num_client`,
`cl`.`nom_client` AS `nom_client`,
`ds`.`nbre_a4` AS `nbre_a4`,
`ds`.`nbre_a3` AS `nbre_a3`,
`ds`.`nbre_autres` AS `nbre_autres`,
((`ds`.`nbre_autres` + `ds`.`nbre_a3`) + `ds`.`nbre_a4`) AS `nbre_total`,
`ds`.`date_scan` AS `date_scan`,`ds`.`qualite` AS `qualite`,
`ds`.`id_operateur` AS `id_operateur`,
`ut`.`nom_complet` AS `nom_complet`,
`ds`.`observations` AS `observations`,
`ds`.`chemin` AS `chemin`
from (((`boite_archive` `ba` left join `documents_scannes` `ds` on((`ds`.`num_boite` = `ba`.`num_boite`)))
left join `clients` `cl` on((`ds`.`num_client` = `cl`.`num_client`)))
left join `utilisateurs` `ut` on((`ds`.`id_operateur` = `ut`.`id_user`)))
The tables are respectively :
documents_scannes : List of scanned documents
boite_archive : List of box that contains the scanned documents
clients : List of customer that issued the scanned documents
utilisateurs : List of personal that are scanning the documents
The joins is performed on the primary keys of the tables.
My objective is to get the list of the scanned documents (documents_scannes) from each box (boite_archive) fetching in the same time the name of the client (from clients table) and the name of the operator who has done the scan (from table utilisateurs).
My problem is when I :
SELECT * FROM documents_scannes_view WHERE num_boite = '1131';
The box number 1131 is empty it contains no scanned documents but I get one row :
Who can help me point the source of my error and how I can correct it ?
Thanks in advance.
I am not sure about the joins in the bottom of the query. It's the source of the issue. How I can fix it to get no results when the box is emprt ?
If you don't want select an empty row where the join columns don't match change to an inner join instead of left join
from (((`boite_archive` `ba` inner join `documents_scannes` `ds` on((`ds`.`num_boite` = `ba`.`num_boite`)))
left join `clients` `cl` on((`ds`.`num_client` = `cl`.`num_client`)))
left join `utilisateurs` `ut` on((`ds`.`id_operateur` = `ut`.`id_user`)))
The LEFT JOIN keyword returns all rows from the left table (table1), with the matching rows in the right table (table2). The result is NULL in the right side when there is no match.

I don't know if the title is correct but here goes my problem.
So, I want to create View in phpmyadmin using data from several tables (picture below), View that represents maintenance for lamps with fields from several tables (substation, post_type, area, lamp_type, failure and maintenance)
Here are tables with connections:
I've manage somehow and created something like this(picture below), which I managed to create using this block of code:
CREATE OR REPLACE VIEW
v_lamp_I
AS
SELECT
lamps.id,
substation.code AS sub_code,
substation.name AS sub_name,
lamps.lamp_code,
post_type.descript AS post_ty,
lamp_type.descript AS lamp_ty,
area.descript AS area_name,
rasvjeta.adress,
DATE_FORMAT(date_maintenance, "%d.%m.%Y.") AS date_main,
lamps.geo_long,
lamps.geo_lat
FROM lamps
INNER JOIN substiation ON substiation.id = lamps.substiation_id
INNER JOIN post_type ON post_type.id = lamps.post_type_id
INNER JOIN lamp_type ON lamp_type.id = lamps.lamp_type_id
INNER JOIN area ON area.id = rasvjeta.area_id
INNER JOIN maintenance ON maintenance.lamps_id = lamps.id
I've managed to create view but the problem is with that view I can see only rows/lamps(sifra_lampe) which were maintained, only 4. In table lamps
I've 24 entries in and only 4 entries for maintenance.But, I want to see all 24 entries and if there was no maintenance for that particular lamp, field can be empty with date format (00-00-00 or it can be NULL) and for entries/lamps that were maintained I want to be visible date field.
Here is table lamps with entries.
And here is view with maintenance date. As you can see there are only 6 entries
I want to see the rest of the entries, for lamps that were not maintained entries can be null or date format like this (00-00-00) and for lamps that were maintained date format can stay the same, in short I want to see all entries not only those which were maintained. Thank you and sorry for long question. I didn't know how to construct meaningful and short question so wrote everything.

I am trying to create an inner-join MySQL Query of two tables:
'swatchset'
->swatchset_id
->swatchset_name
'swatches'
->swatch_id
->swatch_name
->swatch_hex
->etc...
I currently have one record in the 'swatchset' table:
swatchset_id | swatchset_name
8 default
The 'swatches' table is empty.
I want to get as result the 'swatchset'.'swatchset_name'
I guess I don't understand INNER JOIN very well because this Query results nothing:
SELECT `swatchset`.`swatchset_name`, `swatches`.`swatch_id`, `swatches`.`swatch_name`, `swatches`.`swatch_hex`, `swatches`.`swatch_type` FROM `swatchset`
INNER JOIN `swatches`
ON `swatches`.`f_swatchset_id` = `swatchset`.`swatchset_id`
WHERE `swatchset`.`swatchset_id` = '8';
How can I get at least the found 'swatchset' row as result?
Left outer join will fill with nulls columns of second table when not found:
SELECT `swatchset`.`swatchset_name`, `swatches`.`swatch_id`, `swatches`.`swatch_name`, `swatches`.`swatch_hex`, `swatches`.`swatch_type` FROM `swatchset`
LEFT OUTER JOIN `swatches`
ON `swatches`.`f_swatchset_id` = `swatchset`.`swatchset_id`
WHERE `swatchset`.`swatchset_id` = '8';
inner join doesn't return entries from first table without matching ones in second table
I have three tables: nanoProd, nanoFiles, and nanoRelFiles. Third table is used to store the file meta and how they relate to other screens.
I'm getting an error that a column doesn't exist when I know it does and I'm not sure why:
no such column: nanoFiles.fileLoc:
SELECT
prodTable.name AS prodName,
prodTable.intro AS prodIntro,
prodTable.prodText AS nanoText,
nanoFiles.fileLoc AS nanoFile
FROM nanoProd AS prodTable
LEFT JOIN nanoRelFiles on nanoFiles.rid = nanoRelFiles.file_id
LEFT JOIN nanoProd ON nanoProd.rid = nanoRelFiles.item_id
WHERE nanoRelFiles.scr_type = 'prod' AND nanoRelFiles.fileUse = 'list'
You aren't joining to any table called "nanoFiles." You need to JOIN to that table to be able to SELECT from that column. Something like this:
FROM nanoProd AS prodTable
JOIN nanoFiles on ...
LEFT JOIN nanoRelFiles on nanoFiles.rid = nanoRelFiles.file_id
How do you find out who did not contribute to a particular fund raiser that we all just did. There are many titles to the different charities, I however just want to extract the non-contributors for a particular charity title. Is there anyway to do this? When I do the the syntax below it comes up as an empty set. The search is done by way of the table Id matching and left joins. Please see below.
SELECT
moiid,
trim(concat(name.fname,' ' ,name.mname,' ',name.lname)) as Brother,
name.moiid as Members_ID,
sum(otherpay.othpayamt) as NO_Contribution,
quadlt.ltfname as quad
FROM name
LEFT JOIN OTHERPAY ON name.moiid = otherpay.othpaymoiid
LEFT JOIN quadlt ON name.quadlt = quadlt.ltid
WHERE Otherpay.othpaytitle like '%food drive%'
AND otherpay.othpaymoiid IS NULL
AND name.type = 'BOI'
AND name.type <> 'jrboi'
AND name.city = 'SUFFOLK'
GROUP BY brother
ORDER BY name.quadlt, brother
When you add conditions to the where clause for tables that are left joined, you effectively turn them into an inner join, requiring them to return records.
You can move the conditions to the join itself:
SELECT moiid, trim(concat(name.fname,' ' ,name.mname,' ',name.lname)) as Brother, name.moiid as Members_ID, sum(otherpay.othpayamt) as NO_Contribution, quadlt.ltfname as quad
FROM name
LEFT JOIN OTHERPAY
ON name.moiid = otherpay.othpaymoiid
AND Otherpay.othpaytitle like '%food drive%'
LEFT JOIN quadlt ON name.quadlt = quadlt.ltid
WHERE
otherpay.othpaymoiid IS NULL
AND name.type = 'BOI'
AND name.type <> 'jrboi'
AND name.city = 'SUFFOLK'
GROUP BY brother
ORDER BY name.quadlt, brother
