2nd option code = 00000000000555
hi i am try to find out same function like ltrim() of php
SELECT * FROM db1.stock JOIN db2.prodinfo ON replace(db2.prodinfo.code,0000000000,'') = replace(db1.stock.code,0000000000,'') WHERE db1.stock.InvNo ='12' and db2.prodinfo.Cat = 'super'
i rum this temporary. becuse zero might be increase and decrease i
example above. i am just want to remove zero in this query
thanks
try by casting it into numeric,
SELECT *
FROM db1.stock JOIN db2.prodinfo ON
CAST(db2.prodinfo.code AS SIGNED) = CAST(db1.stock.code AS SIGNED)
WHERE db1.stock.InvNo ='12' and db2.prodinfo.Cat = 'super'
or
SELECT *
FROM db1.stock JOIN db2.prodinfo ON
CAST(db2.prodinfo.code AS DECIMAL(15,0)) = CAST(db1.stock.code AS AS DECIMAL(15,0))
WHERE db1.stock.InvNo ='12' and db2.prodinfo.Cat = 'super'

I want to select data from my database table with join query, but my it doesn't work.
My query:
$this->db->select();
$this->db->from('we');
$this->db->join('schedule', 'schedule.itemid = we.cid');
$this->db->join('schedule', 'schedule.itemtype = 'testitem'');
$this->db->where('we.isActive','Y');
This line makes problem with schedule.itemtype = 'testitem':
$this->db->join('schedule', 'schedule.itemtype = 'testitem'');
How can I solve this?
You don't need to join same table twice.
But just to extend ON clause:
$this->db->select();
$this->db->from('we');
$this->db->join('schedule', 'schedule.itemid = we.cid AND schedule.itemtype = \'testitem\'');
$this->db->where('we.isActive','Y');
try
$this->db->select();
$this->db->from("we");
$this->db->join("schedule", "schedule.itemid = we.cid");
$this->db->where("schedule.itemtype","testitem");
$this->db->where("we.isActive","Y");
I believe there are two problems here. The first problem is that you are using one too many quotes in the second join line in your query:
You have: $this->db->join('schedule', 'schedule.itemtype='testitem''); < extra quote
It should be: $this->db->join('schedule', 'schedule.itemtype=testitem');
Second problem: your join doesnt make sense.
Your statement:
$this->db->select();
$this->db->from('we');
$this->db->join('schedule', 'schedule.itemid = we.cid');
$this->db->join('schedule', 'schedule.itemtype = testitem');
$this->db->where('we.isActive','Y');
Translates to:
SELECT * FROM we
JOIN schedule ON schedule.itemid = we.cid
JOIN schedule ON schedule.itemtype = testitem
WHERE we.isActive = Y
As you can see you are joining the same table twice on different lines, not only that but what table does "testitem" belong to? We are left to assume that you perhaps want the join where itemtype = testitem which will mean this:
SELECT * FROM we
JOIN schedule ON schedule.itemid = we.cid
WHERE schedule.itemtype = testitem
AND we.isActive = Y
Therefore your final Codeigniter query should be:
$this->db->select('*');
$this->db->from('we');
$this->db->join('schedule', 'schedule.itemid = we.cid');
$this->db->where('schedule.itemtype', 'testitem');
$this->db->where('we.isActive','Y');
This will work:
$this->db->join('schedule', 'schedule.itemid = we.cid');
$this->db->where('we.isActive','Y');
$this->db->where('schedule.itemtype', 'testitem');
$this->db->get('we');
$this->db->query('select we_tbl.c_name from we we_tbl,schedule sch_tbl where sch_tbl.itemid = we_tbl.cid AND we_tbl.idActive = '.$activeData);
Try this query according to your problem this could get the data you need.
I've tested on different database but i tried to perform what you're trying to get. https://www.w3schools.com/sql/trysql.asp?filename=trysql_op_in
select
pro_tbl.ProductName,
cat_tbl.CategoryName ,
sup_tbl.SupplierName
from
Products pro_tbl,
Suppliers sup_tbl,
Categories cat_tbl
where
pro_tbl.SupplierID = sup_tbl.SupplierID AND
pro_tbl.CategoryID = cat_tbl.CategoryID;
Two possible problems, depending on what your desired outcome is:
If you need to make two joins and are getting an error with the second join clause, try using double quotes to enclose the constant value on the condition or you'll get a parse error:
$this->db->join('schedule', 'schedule.itemtype = "testitem"');
If you need to join only once with multiple conditions, use parentheses:
$this->db->select('*');
$this->db->from('we');
$this->db->join('schedule', '(schedule.itemid = we.cid AND schedule.itemtype="testitem")');
$this->db->where('we.isActive','Y');
You query is equivalent to writing:
select * from we
inner join schedule on schedule.itemid = we.cid
inner join schedule on schedule.itemtype = "testitem"
where we.isActive = 'Y'
but what you seem to need is
select * from we
inner join schedule on (schedule.itemid = we.cid AND schedule.itemtype = "testitem")
where we.isActive = 'Y'
On your original query, you are doing two joins. In the latter, you'll do only one with multiple conditions.
I'm trying to use id_program result from the availability table inside a string in LEFTJOIN, is it possible?
I tried using this {post.id_program} but its not working.
SELECT *
FROM availability post
LEFT JOIN postmeta meta5 ON meta5.post_id = post.id_post
AND meta5.meta_key = 'items_iti_port_{post.id_program}_nights_iti_port'
WHERE post.id_post=462
EDIT:
http://sqlfiddle.com/#!9/aeb4a7/3
I see two ways..
Using CONCAT():
meta5.meta_key = CONCAT('items_iti_port_', post.id_program, '_nights_iti_port')
With REPLACE():
meta5.meta_key = REPLACE('items_iti_port_%_nights_iti_port', '%', post.id_program)
So here is the issue. I'm trying to write a new fillrate report because the one built in is not good enough... I'm trying to run a single select statement to return both, a count of how many times an item was ordered for a specific month, and then also a count of how many times it was invoiced/shipped in full.
This code is obviously wrong, I also currently have it restricted to only look at AUG of 2015, but that is just to simplify results during testing.
I can't figure out how to do the 2nd count... This is what I was trying (brain stuck on old for each loop logic):
select inv_mast.item_id,
inv_mast.item_desc,
"YEAR" = year(oe_line.required_date),
"MONTH" = month(oe_line.required_date),
"ORDERS" = count(1),
"HITS" = (
select count(1)
from invoice_line
where invoice_line.order_no = oe_line.order_no
and invoice_line.oe_line_number = oe_line.line_no
and invoice_line.qty_shipped = oe_line.qty_ordered
)
from oe_line,
inv_mast,
inv_loc
where inv_mast.inv_mast_uid = oe_line.inv_mast_uid
and inv_mast.delete_flag = 'N'
and inv_mast.inv_mast_uid = inv_loc.inv_mast_uid
and inv_loc.location_id = '101'
and year(oe_line.required_date) = '2015'
and month(oe_line.required_date) = '8'
group by inv_mast.item_id,
inv_mast.item_desc,
year(oe_line.required_date),
month(oe_line.required_date)
order by inv_mast.item_id
To me it would seem like you could rewrite the query to use a left join on the invoice_line table instead. Without any proper test data I can't guarantee it is correct, but I think it should be.
Besides the left join I also changed to explicit joins and moved the aliases as I don't think MySQL supports the alias = column syntax.
select inv_mast.item_id,
inv_mast.item_desc,
year(o.required_date) as "YEAR",
month(o.required_date) as "MONTH",
count(1) as "ORDERS",
count(invoice_line.order_no) as "HITS"
from oe_line o
join inv_mast on inv_mast.inv_mast_uid = o.inv_mast_uid
join inv_loc on inv_mast.inv_mast_uid = inv_loc.inv_mast_uid
left join invoice_line on invoice_line.order_no = o.order_no
and invoice_line.oe_line_number = o.line_no
and invoice_line.qty_shipped = o.qty_ordered
where inv_mast.delete_flag = 'N'
and inv_loc.location_id = '101'
and year(o.required_date) = '2015'
and month(o.required_date) = '8'
group by inv_mast.item_id,
inv_mast.item_desc,
year(o.required_date),
month(o.required_date)
order by inv_mast.item_id;
i got this error:
for the right syntax to use near 'INNER JOIN oferta B ON A.oferta_id_oferta = B.id_oferta AND B.oferta = "design' at line 4
i can't make a inner join inside a where clause ? or exists other problem with this query ?
UPDATE `oferta_has_tags` A
SET fraccao = "1/7"
WHERE (
INNER JOIN oferta B
ON A.oferta_id_oferta = B.id_oferta
AND B.oferta = "designer"
AND B.estado = 0)
Express it as a simple IN:
UPDATE oferta_has_tags
SET fraccao = '1/7'
WHERE oferta_id_oferta IN (
SELECT id_oferta
FROM oferta
WHERE oferta = 'designer'
AND estado = 0)
Also, changed double quotes (") to single quotes (') - using double quotes will cause an error
The query is wrong. It must have SELECT and FROM clauses:
It must be something like this:
UPDATE oferta_has_tags A
SET fraccao = "1/7"
WHERE id = ( SELECT id FROM yourtable WHERE something = somevalue )
Make sure that the subquery should return exactly 1 value. If you want to update multiple records using above query, replace "=" with "IN". Like this:
UPDATE oferta_has_tags A
SET fraccao = "1/7"
WHERE id IN ( SELECT id FROM yourtable WHERE something = somevalue )
Hope it helps...
How can I group a query result by a field that is not saved in the database.
For example I want to group the result by duration which is came from subtraction of start time and end time.
here is how i find out the duration
date1= $row_TicketRS['CloseDate'];
$date2 = $row_TicketRS['OpenDate'];
$diff = abs(strtotime($date2) - strtotime($date1));
$days = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24)/ (60*60*24));
if ( $days > 0)
{
$time1 = $row_TicketRS['OpenTime'];
$time2= $row_TicketRS['CloseTime'];
$t1=($time1);
$t2=($time2);
$end=('14:30');
$start=('07:30');
$n = $end- $t1;
$n2 = $t2- $start;
$Hours2 = floor(($n+$n2)+(($days-1)*7));
echo $Hours2.' Hours';
but know i do not know how to add it to the query
here is my query
$strQuery = "SELECT count(`ticket`.TicketID) as TotOutput, department.`DeptName` FROM `ticket`, `user`, department where ticket.OwnerID = user.EmpNo and user.`DepartmentID` = department.`DepartmentID` and OpenDate between'".$DateFrom."' And '".$DateTo."'"
It'd be better to have details, but a derived table/inline view would allow you to group by a computed value:
SELECT x.duration,
COUNT(*)
FROM (SELECT t.col,
t.end_time - t.start_time AS duration
FROM YOUR_TABLE t) x
GROUP BY x.duration
How about adding that computed value to the query with an alias like this:
SELECT some_fields, end - start AS duration FROM table ORDER BY duration
dont put alias for hidden column , use directly
exmaple:
SELECT id, FLOOR(value/100)
FROM tbl_name
GROUP BY id, FLOOR(value/100);
Reference
MySQL permits expressions in GROUP BY
clauses, so the alias is unnecessary:
