I can't get the JOIN syntax correct to alter this existing MySQL query in PHP to include a join from another table. I have another table specified as DB_TABLE2 that contains columns InvmNumr and InvmDesc. The InvmNumr and InvlNumr are the exact same value in each table and I need to display InvmDesc from Table 2 in this query?
$res = mysql_query('SELECT LocId, InvlNumr, InvlQuant FROM ' . DB_TABLE1
. ' WHERE LocId = \'' . mysql_real_escape_string($cType) . '\'
AND InvlNumr = \'' . mysql_real_escape_string($br) . "'");
$markup = '';
Read up on LEFT JOIN vs INNER JOIN depending on how your data is stored in your DB_TABLE2 table.
$res = mysql_query('SELECT ' . DB_TABLE1 . '.LocId, ' . DB_TABLE1 . '.InvlNumr, ' .
DB_TABLE1 . '.InvlQuant, ' . DB_TABLE2 . '.InvmDesc
FROM ' . DB_TABLE1 . ' LEFT JOIN ' . DB_TABLE2 . ' ON ' .
DB_TABLE1 . '.InvlNumr = ' . DB_TABLE2 . '.InvmNumr
WHERE ' . DB_TABLE1 . '.LocId = \'' . mysql_real_escape_string($cType) . '\'
AND ' . DB_TABLE1 . '.InvlNumr = \'' . mysql_real_escape_string($br) . "'");
try this
SELECT db1.LocId,db1.InvlNumr,db1.InvlQuant
FROM DB_TABLE1 db1
INNER JOIN DB_TABLE2 db2 ON db1.InvlNumr = db2.InvlNumr
WHERE dbq.LocId = $cType
AND db1.InvlNumr = $br

I am working in PHP with Laravel and the page I have been given contains 3 SQL queries on separate tables but using the same criteria. I have tried combining them but the combined results are slower than the original. What can I do to increase rather than decrease the speed of these queries?
Here are my queries:
$searchFor = 'debtor_name';
$searchForBKR = 'estate_name';
$searchForHypotech = 'hypleg_lot_credit_debtor_name';
$arraySearch = explode(",", $request->input('name'));
$search = $searchFor . ' like "%';
$bkrSearch = $searchForBKR . ' like "%';
$hypotechSearch = $searchForHypotech . ' like "%';
$searchCompany = $searchCompanyFor . ' like "%';
$searchPlaintiff = $searchPlaintiffFor . ' like "%';
$searchDefendantName = $searchDefendantNameFor . ' like "%';
$search = $search . $arraySearch[0] . '%"';
$bkrSearch = $bkrSearch . $arraySearch[0] . '%"';
$hypotechSearch = $hypotechSearch . $arraySearch[0] . '%"';
$searchCompany = $searchCompany . $arraySearch[0] . '%"';
$searchPlaintiff = $searchPlaintiff . $arraySearch[0] . '%"';
$searchDefendantName = $searchDefendantName . $arraySearch[0] . '%"';
for ($i = 1; $i < count($arraySearch); $i++) {
$search = $search . " or " . $searchFor . ' like "%' . $arraySearch[$i] . '%"';
$bkrSearch = $bkrSearch . " or " . $searchForBKR . ' like "%' . $arraySearch[$i] . '%"';
$hypotechSearch = $hypotechSearch . " or " . $searchForHypotech . ' like "%' . $arraySearch[$i] . '%"';
$searchCompany = $searchCompany . " or " . $searchCompanyFor . ' like "%' . $arraySearch[$i] . '%"';
$searchPlaintiff = $searchPlaintiff . " or " . $searchPlaintiffFor . ' like "%' . $arraySearch[$i] . '%"';
$searchDefendantName = $searchDefendantName . " or " . $searchDefendantNameFor . ' like "%' . $arraySearch[$i] . '%"';
}
$sis = DB::select('select debtor_name, count(*) as sis_total from equifax_sis_regions' . $search . ')
group by debtor_name');
$bkr = DB::select('select estate_name as debtor_name, count(*) as bkr_total from equifax_bkr_regions' . $bkrSearch . ')
group by estate_name');
$hypotech = DB::select('select hypleg_lot_credit_debtor_name as debtor_name, count(*) as hypotech_total from equifax_hypotech_regions' . $hypotechSearch . ')
group by hypleg_lot_credit_debtor_name');
I have tried replacing the 3 queries by using outer joins like this:
$other = 'select debtor_name, count(debtor_name) as sis_total,
estate_name as debtor_name, count(estate_name) as bkr_total
hypleg_lot_credit_debtor_name as debtor_name, count(hypleg_lot_credit_debtor_name) as hypotech_total
from equifax_sis_regions outer join equifax_bkr_regions on (equifax_sis_regions.debtor_name=estate_name)
outer join equifax_hypotech_regions on (equifax_sis_regions.debtor_name=hypleg_lot_credit_debtor_name)
WHERE (' . $search . ') OR ' . $bkrSearch . ') OR (' . $hypotechSearch . ')
GROUP BY debtor_name, estate_name, hypleg_lot_credit_debtor_name';
but that is a much slower query to run. The database contains over 4 million rows and the difference in API calls to the 2 query versions is ~53 seconds for the original and ~78 seconds for the combined form. Is there any way I can modify this combined query to be faster rather than slower?
Thanks in advance
You can use the UNION ALL operator to combine multiple SELECT statements. You could combine them like this:
SELECT debtor_name, SUM(sis_total), SUM(bkr_total), SUM(hypotech_total)
FROM (
SELECT debtor_name, COUNT(*) AS sis_total, 0 AS bkr_total, 0 AS hypotech_total
FROM equifax_sis_regions
-- add where clause here
GROUP BY debtor_name
UNION ALL
SELECT estate_name AS debtor_name, 0 AS sis_total, COUNT(*) AS bkr_total, 0 AS hypotech_total
FROM equifax_bkr_regions
-- add where clause here
GROUP BY estate_name
UNION ALL
SELECT hypleg_lot_credit_debtor_name AS debtor_name, 0 AS sis_total, 0 AS bkr_total, COUNT(*) AS hypotech_total
FROM equifax_hypotech_regions
-- add where clause here
GROUP BY hypleg_lot_credit_debtor_name
) derived
GROUP BY debtor_name;

Anyone can help me?
When you use GROUP BY you need to group by all the fields that you are not using an aggregate function against (ie: SUM, MAX, etc).
GROUP BY is also not part of a WHERE clause; it stands alone.
Given your query has no aggregate functions, I don't see why you're using GROUP BY at all.
Try this.
$Read->FullRead("SELECT an_promo_page_tipo_blocos.title,"

I have 2 tables in Joomla:
Entitlements:(User_id, entitlement_amount, reference_year)
Charges:(User_id, charge_amount, reference_year)
Both must be linked to the users core table using the User_id as a foreign key.
Entitlements has entries with users not necessarily included in Charges. Charges table has entries not necessarily included in the Entitlements.
I need to link all 3 tables in such a way so that in each row, I will have the User_id(name), the SUM(entitlement_amount) and the SUM(charge_amount).
The results must be grouped by employee, reference_year.
If no SUM is calculated then to display 0.
Here is my code below.
$query->select( $this->getState(
'list.select',
'a.id,' .
'a.employee_id,' .
'ac.employee_id,' .
'a.reference_year,' .
'ac.reference_year,' .
'u.name,' .
'SUM(a.entitlement), ' .
'SUM(ac.charge)'));
$query->from($db->quoteName('#__employee_entitlement').' AS a');
$query->join('LEFT OUTER', $db->quoteName('#__users', 'u') . ' ON (' .
$db->quoteName('a.employee_id') . ' = ' . $db->quoteName('u.id') .')');
$query->join('LEFT', $db->quoteName('#__absence_charge', 'ac') . ' ON ('
. $db->quoteName('ac.employee_id') . ' = ' . $db->quoteName('u.id') .
')');
$query->group($db->quoteName('a.employee_id')) ;
$query->group($db->quoteName('a.reference_year')) ;
Thanks.
How can I adapt the following query to JDatabase?
SELECT

,c.EMAIL usu_email
,IF(IFNULL(u.block, 1) = 0, 'Activo', 'Inactivo') usu_estado
,COUNT(ct.ctf_id) nroCertificados
FROM
cargacliente c
INNER JOIN

ON (crg_id = cargas_id)
AND (crg_status = 'Ok')
INNER JOIN

ON (ctf_sede = SEDE)
AND (ctf_nit = NIT)
LEFT JOIN
database_1.bml_users u
ON (id = user_id)
GROUP BY
c.NIT
,c.SEDE
ORDER BY
usu_razonSocial
,usu_nit
,usu_sede;
This is Joomla 2.5.4.
I have read this post but I couldn't do it.
I tried to do it in this way:
<?php
$query
->select($db->quoteName(array('c.RAZONSOCIAL AS usu_razonSocial', 'c.NIT usu_nit', 'c.SEDE usu_sede', 'c.EMAIL usu_email', 'IF(IFNULL(u.block, 1) = 0, \'Activo\', \'Inactivo\') usu_estado', 'COUNT(ct.ctf_id) nroCertificados')))
->from($db->quoteName('database_2.cargacliente', 'c'))
->join('INNER', $db->quoteName('database_2.cargas','a') . ' ON (' . $db->quoteName('a.crg_id') . ' = ' . $db->quoteName('database_2.cargacert.cargas_id') . ') AND (' . $db->quoteName('a.crg_status') . ' = \'Ok\')')
->join('INNER', $db->quoteName('database_2.certificados','b') . ' ON (' . $db->quoteName('b.ctf_sede') . ' = ' . $db->quoteName('database_2.cargacliente.SEDE') . ') AND (' . $db->quoteName('b.ctf_nit') . ' = NIT)')
->join('LEFT', $db->quoteName('joomla_database.bml_users', 'u') . ' ON (' . $db->quoteName('database_2.usuario.usu_id') . ' = ' . $db->quoteName('joomla_database.bml_users.user_id') . ')')
->group(array('c.NIT', 'c.SEDE'))
->order(array('database_2.usuario.usu_razonSocial', 'database_2.usuario.usu_nit', 'database_2.usuario.usu_sede'));
?>
The error shown is the following:
500 - Ha ocurrido un error.
Unknown column 'c.RAZONSOCIAL usu_razonSocial' in 'field list' SQL=SELECT `c`.`RAZONSOCIAL usu_razonSocial`,`c`.`NIT usu_nit`,`c`.`SEDE usu_sede`,`c`.`EMAIL usu_email`,`IF(IFNULL(u`.`block, 1) = 0, 'Activo', 'Inactivo') usu_estado`,`COUNT(ct`.`ctf_id) nroCertificados` FROM `biochemical`.`cargacliente` AS `c` INNER JOIN `biochemical`.`cargas` AS `a` ON (`a`.`crg_id` = `biochemical`.`cargacert`.`cargas_id`) AND (`a`.`crg_status` = 'Ok') INNER JOIN `biochemical`.`certificados` AS `b` ON (`b`.`ctf_sede` = `biochemical`.`cargacliente`.`SEDE`) AND (`b`.`ctf_nit` = NIT) LEFT JOIN `biochemical_bml`.`bml_users` AS `u` ON (`biochemical`.`usuario`.`usu_id` = `biochemical_bml`.`bml_users`.`user_id`) GROUP BY c.NIT,c.SEDE ORDER BY biochemical.usuario.usu_razonSocial,biochemical.usuario.usu_nit,biochemical.usuario.usu_sede
The changes were the following:
Remove the first $db->quoteName() in the SELECT statement.
Modify ALIAS from tables.
LEFT JOIN modification.
The final code is the following:
$query
->select(array('c.RAZONSOCIAL AS usu_razonSocial', 'c.NIT AS usu_nit', 'c.SEDE AS usu_sede', 'c.EMAIL AS usu_email', 'IF(IFNULL(u.block, 1) = 0, \'Activo\', \'Inactivo\') AS usu_estado', 'COUNT(b.ctf_id) AS nroCertificados'))
->from($db->quoteName('database_2.cargacliente', 'c'))
->join('INNER', $db->quoteName('database_2.cargas','a') . ' ON (' . $db->quoteName('a.crg_id') . ' = ' . $db->quoteName('c.cargas_id') . ') AND (' . $db->quoteName('a.crg_status') . ' = \'Ok\')')
->join('INNER', $db->quoteName('database_2.certificados','b') . ' ON (' . $db->quoteName('b.ctf_sede') . ' = ' . $db->quoteName('c.SEDE') . ') AND (' . $db->quoteName('b.ctf_nit') . ' = c.NIT)')
->join('LEFT', $db->quoteName('joomla_database.bml_users', 'u') . ' ON (' . $db->quoteName('c.user_id') . ' = ' . $db->quoteName('u.id') . ')')
->group(array('c.NIT', 'c.SEDE'))
->order(array('usu_razonSocial', 'usu_nit', 'usu_sede'));
This is a bit difficult to say what the problem is without having the right environment.
I would suggest to debug through the driver to see where it fails.
You can of course also put the query direct through the "setQuery" method. It would be however compatible with MySQL only.
But, once again, please update your Joomla! to the latest version ASAP.
problems with a lot of users have the names of long in who liked for this Story
So How can I sort users by number of published links in who voted.
in libs/htm1.php
function who_voted($storyid, $avatar_size){
// this returns who voted for a story
// eventually add support for filters (only show friends, etc)
global $db;
if (!is_numeric($storyid)) die();
$sql = 'SELECT ' . table_votes . '.*, ' . table_users . '.* FROM ' . table_votes . ' INNER JOIN ' . table_users . ' ON ' . table_votes . '.vote_user_id = ' . table_users . '.user_id WHERE (((' . table_votes . '.vote_value)>0) AND ((' . table_votes . '.vote_link_id)='.$storyid.') AND (' . table_votes . '.vote_type= "links")) AND user_level<>"god" AND user_level<>"Spammer"';
//echo $sql;
$voters = $db->get_results($sql);
$voters = object_2_array($voters);
foreach($voters as $key => $val){
$voters[$key]['Avatar_ImgSrc'] = get_avatar($avatar_size, "", $val['user_login'], $val['user_email']);
}
return $voters;
I found these lines in topusers.php, but not for a friendly experience in writing function correctly
case 2: // sort users by number of published links
$select = "SELECT user_id, count(*) as count ";
$from_where = " FROM " . table_links . ", " . table_users . " WHERE link_status = 'published' AND link_author=user_id AND user_level NOT IN ('god','Spammer') AND (user_login!='anonymous' OR user_lastip) GROUP BY link_author";
$order_by = " ORDER BY count DESC ";
break;
