Here is the situation:
I search for Persons with ID (empr.empr_cb)
that has bill(s) to pay (transactions.montant)
this refers to transactions.compte_id
which is identical to comptes.id_compte
this refers to comptes.proprio.id
which is identical to empr.id_empr
that would give us the Person ID (empr.empr_cb)
I tried this, but I don't know what joins to set (cross Join?):
SELECT `empr`.`empr_cb`,`transactions`.`montant`
FROM `empr`,`comptes`,`transactions`
WHERE `transactions`.`montant` > `0`
AND `transactions`.`encaissement` = `0`
AND `transactions`.compte_id` = `comptes`.`id_compte`
AND `comptes`.`proprio_id` = `id_empr`
Any ideas how to put the joins?
This query is already using implicit INNER JOINs. It can be rewritten this way:
SELECT empr.empr_cb
, transactions.montant
FROM empr
JOIN comptes ON comptes.proprio_id = empr.id_empr
JOIN transactions ON transactions.compte_id = comptes.id_compte
WHERE transactions.encaissement = 0
AND transactions.montant > 0

I'm trying to join 4 tables that have a somewhat complex relationship. Because of where this will be used, it needs to be contained in a single query, but I'm having trouble since the primary query and the IN clause query both join 2 tables together and the lookup is on two columns.
The goal is to input a SalesNum and SalesType and have it return the Price
Tables and relationships:
sdShipping
SalesNum[1]
SalesType[2]
Weight[3]
sdSales
SalesNum[1]
SalesType[2]
Zip[4]
spZones
Zip[4]
Zone[5]
spPrices
Zone[5]
Price
Weight[3]
Here's my latest attempt in T-SQL:
SELECT
spp.Price
FROM
spZones AS spz
LEFT OUTER JOIN
spPrices AS spp ON spz.Zone = spp.Zone
WHERE
(spp.Weight, spz.Zip) IN (SELECT ship.Weight, sales.Zip
FROM sdShipping AS ship
LEFT OUTER JOIN sdSales AS sales ON sales.SalesNum = ship.SalesNum
AND sales.SalesType = ship.SalesType
WHERE sales.SalesNum = (?)
AND ship.SalesType = (?));
SQL Server Management Studio says I have an error in my syntax near ',' (appropriately useless error message). Does anybody have any idea whether this is even allowed in Microsoft's version of SQL? Is there perhaps another way to accomplish it? I've seen the multi-key IN questions answered on here, but never in the case where both sides require a JOIN.
Many databases do support IN on tuples. SQL Server is not one of them.
Use EXISTS instead:
SELECT spp.Price
FROM spZones spz LEFT OUTER JOIN
spPrices spp
ON spz.Zone = spp.Zone
WHERE EXISTS (SELECT 1
FROM sdShipping ship LEFT JOIN
sdSales sales
ON sales.SalesNum = ship.SalesNum AND
sales.SalesType = ship.SalesType
WHERE spp.Weight = ship.Weight AND spz.Zip = sales.Zip AND
sales.SalesNum = (?) AND
ship.SalesType = (?)
);
My title is probably not very clear, so I made a little schema to explain what I'm trying to achieve. The xxxx_uid labels are foreign keys linking two tables.
Goal: Retrieve a column from the grids table by giving a proj_uid value.
I'm not very good with SQL joins and I don't know how to build a single query that will achieve that.
Actually, I'm doing 3 queries to perform the operation:
1) This gives me a res_uid to work with:
select res_uid from results where results.proj_uid = VALUE order by res_uid asc limit 1"
2) This gives me a rec_uid to work with:
select rec_uid from receptor_results
inner join results on results.res_uid = receptor_results.res_uid
where receptor_results.res_uid = res_uid_VALUE order by rec_uid asc limit 1
3) Get the grid column I want from the grids table:
select grid_name from grids
inner join receptors on receptors.grid_uid = grids.grid_uid
where receptors.rec_uid = rec_uid_VALUE;
Is it possible to perform a single SQL that will give me the same results the 3 I'm actually doing ?
You're not limited to one JOIN in a query:
select grids.grid_name
from grids
inner join receptors
on receptors.grid_uid = grids.grid_uid
inner join receptor_results
on receptor_results.rec_uid = receptors.rec_uid
inner join results
on results.res_uid = receptor_results.res_uid
where results.proj_uid = VALUE;
select g.grid_name
from results r
join resceptor_results rr on r.res_uid = rr.res_uid
join receptors rec on rec.rec_uid = rr.rec_uid
join grids g on g.grid_uid = rec.grid_uid
where r.proj_uid = VALUE
a small note about names, typically in sql the table is named for a single item not the group. thus "result" not "results" and "receptor" not "receptors" etc. As you work with sql this will make sense and names like you have will seem strange. Also, one less character to type!
I have a problem to join thoses 4 tables
Model of my database
I want to count the number of reservations with different sorts (user [mrbs_users.id], room [mrbs_room.room_id], area [mrbs_area.area_id]).
Howewer when I execute this query (for the user (id=1) )
SELECT count(*)
FROM mrbs_users JOIN mrbs_entry ON mrbs_users.name=mrbs_entry.create_by
JOIN mrbs_room ON mrbs_entry.room_id = mrbs_room.id
JOIN mrbs_area ON mrbs_room.area_id = mrbs_area.id
WHERE mrbs_entry.start_time BETWEEN "145811700" and "1463985000"
or
mrbs_entry.end_time BETWEEN "1458120600" and "1463992200" and mrbs_users.id = 1
The result is the total number of reservations of every user, not just the user who has the id = 1.
So if anyone could help me.. Thanks in advance.
Use parentheses in the where clause whenever you have more than one condition. Your where is parsed as:
WHERE (mrbs_entry.start_time BETWEEN "145811700" and "1463985000" ) or
(mrbs_entry.end_time BETWEEN "1458120600" and "1463992200" and
mrbs_users.id = 1
)
Presumably, you intend:
WHERE (mrbs_entry.start_time BETWEEN 145811700 and 1463985000 or
mrbs_entry.end_time BETWEEN 1458120600 and 1463992200
) and
mrbs_users.id = 1
Also, I removed the quotes around the string constants. It is bad practice to mix data types, and in some databases, the conversion between types can make the query less efficient.
The problem you've faced caused by the incorrect condition WHERE.
So, should be:
WHERE (mrbs_entry.start_time BETWEEN 145811700 AND 1463985000 )
OR
(mrbs_entry.end_time BETWEEN 1458120600 AND 1463992200 AND mrbs_users.id = 1)
Moreover, when you use only INNER JOIN (JOIN) then it be better to avoid WHERE clause, because the ON clause is executed before the WHERE clause, so criteria there would perform faster.
Your query in this case should be like this:
SELECT COUNT(*)
FROM mrbs_users
JOIN mrbs_entry ON mrbs_users.name=mrbs_entry.create_by
JOIN mrbs_room ON mrbs_entry.room_id = mrbs_room.id
AND
(mrbs_entry.start_time BETWEEN 145811700 AND 1463985000
OR ( mrbs_entry.end_time BETWEEN 1458120600 AND 1463992200 AND mrbs_users.id = 1)
)
JOIN mrbs_area ON mrbs_room.area_id = mrbs_area.id
I have a DB2 query as follows:
SELECT DISTINCT RETAILMASTERFILE.DOIDCD AS "RETAILMASTERFILE_DOIDCD",
RETAILMASTERFILE.COCOMO AS "RETAILMASTERFILE_COCOMO",
#XENOS.CUSTREF AS "XENOS_CUSTREF",
#XENOS.ADDUDT AS "XENOS_ADDUDT",
#XENOS.ADUPDD AS "XENOS_ADUPDD",
#XENOS.ADUPDT AS "XENOS_ADUPDT",
#XENOS.ADSTAT AS "XENOS_ADSTAT"
FROM RETAILMASTERFILE INNER JOIN
#XENOS ON RETAILMASTERFILE.DOCOMP = #XENOS.ADCOMP
AND RETAILMASTERFILE.COCOMO = #XENOS.ADDELN
WHERE (RETAILMASTERFILE.DOIDCD = 'CUST008')
AND (RETAILMASTERFILE.COCOMO = '345126032')
AND (RETAILMASTERFILE.DOCOMP = 'LONDON')
The problem is #XENOS.ADUPDT may not be unique which gives me an unwanted duplicate record.
Is there any way I can exclude this from consideration ? Everything I've tried so far within my limited knowledge and crude understanding of group by has so far broken my query.
Use GROUP BY instead:
SELECT RETAILMASTERFILE.DOIDCD AS "RETAILMASTERFILE_DOIDCD",
RETAILMASTERFILE.COCOMO AS "RETAILMASTERFILE_COCOMO",
#XENOS.CUSTREF AS "XENOS_CUSTREF",
#XENOS.ADDUDT AS "XENOS_ADDUDT",
#XENOS.ADUPDD AS "XENOS_ADUPDD",
MAX(#XENOS.ADUPDT) AS "XENOS_ADUPDT",
#XENOS.ADSTAT AS "XENOS_ADSTAT"
FROM RETAILMASTERFILE INNER JOIN
#XENOS
ON RETAILMASTERFILE.DOCOMP = #XENOS.ADCOMP AND
RETAILMASTERFILE.COCOMO = #XENOS.ADDELN
WHERE (RETAILMASTERFILE.DOIDCD = 'CUST008') AND (RETAILMASTERFILE.COCOMO = '345126032') AND
(RETAILMASTERFILE.DOCOMP = 'LONDON')
GROUP BY RETAILMASTERFILE.DOIDCD,
RETAILMASTERFILE.COCOMO,
#XENOS.CUSTREF,
#XENOS.ADDUDT,
#XENOS.ADUPDD,
#XENOS.ADSTAT;
I`m working on some sql queries to get some data out of a table; I have made 2 queries for the
same data but both give another result. The 2 queries are:
SELECT Samples.Sample,
data_overview.Sample_Name,
data_overview.Sample_Group,
data_overview.NorTum,
data_overview.Sample_Plate,
data_overview.Sentrix_ID,
data_overview.Sentrix_Position,
data_overview.HybNR,
data_overview.Pool_ID
FROM tissue INNER JOIN (
( patient INNER JOIN data_overview
ON patient.Sample = data_overview.Sample)
INNER JOIN Samples ON
(data_overview.Sample_id = Samples.Sample_id) AND
(patient.Sample = Samples.Sample)
) ON
(tissue.Sample_Name = data_overview.Sample_Name) AND
(tissue.Sample_Name = patient.Sample_Name)
WHERE data_overview.Sentrix_ID= 1416198
OR data_overview.Pool_ID='GS0005701-OPA'
OR data_overview.Pool_ID='GS0005702-OPA'
OR data_overview.Pool_ID='GS0005703-OPA'
OR data_overview.Pool_ID='GS0005704-OPA'
OR data_overview.Sentrix_ID= 1280307
ORDER BY Samples.Sample;")
And the other is
SELECT Samples.Sample,
data_overview.Sample_Name,
data_overview.Sample_Group,
data_overview.NorTum,
data_overview.Sample_Plate,
data_overview.Sentrix_ID,
data_overview.Sentrix_Position,
data_overview.HybNR,
data_overview.Pool_ID
FROM tissue INNER JOIN
(
(patient INNER JOIN data_overview
ON patient.Sample = data_overview.Sample)
INNER JOIN Samples ON
(data_overview.Sample_id = Samples.Sample_id)
AND (patient.Sample = Samples.Sample)) ON
(tissue.Sample_Name = data_overview.Sample_Name)
AND (tissue.Sample_Name = patient.Sample_Name)
WHERE ((
(data_overview.Sentrix_ID)=1280307)
AND (
(data_overview.Pool_ID)="GS0005701-OPA"
OR (data_overview.Pool_ID)="GS0005702-OPA"
OR (data_overview.Pool_ID)="GS0005703-OPA"
OR (data_overview.Pool_ID)="GS0005704-OPA"))
OR (((data_overview.Sentrix_ID)=1416198))
ORDER BY data_overview.Sample;
The one in the top is working quite well but it still won't filter the sentrix_ID.
The second 1 is created with Access but when I try to run this Query in R it gave
a unexpected symbol error. So if anyone knows how to create a query that filter POOL_ID and Sentrix_id with the given parameters thanks in advance
Is it a case of making the where clause something like this:
WHERE Sentrix_ID = 1280307 AND (Pool_ID = 'VAL1' OR Pool_ID = 'VAL2' OR Pool_ID = 'VAL3')
i.e. making sure you have brackets around the "OR" components?
Maybe you meant:
...
WHERE data_overview.Sentrix_ID IN (1280307,1416198 )
AND data_overview.Pool_ID IN ("GS0005701-OPA", "GS0005702-OPA", "GS0005703-OPA" ,"GS0005704-OPA")
;
