When I query I do not get match list side by side and database reference fails, why?
I tried using one connection and two different schemas, first schema name table has same reference details with second table column, and I would like to compare side by side what equals exactly from rw.reference table 1, with table 2 qt.ref_number because they should match between both. I only get output data from top first query with rd.reference and second table does not list anything with, qt.ref_number, why postgresql does not cross database reference?
Query:
Select distinct
rd.reference,
region1_scorecard
From local_dev.user.rawdata rd
Inner join customerid as id
on rd.site=id.site
union all
Select distinct
qt.ref_number,
region2_decision
From local_dev.account.quote qt
Inner join rep_id id
on qt.application=id.application
Order by rd.reference

I have a list of phone numbers that am sending messages to. in table A I record all the delivery status of each number.
I created another table B and stored some contacts in it.
I want an SQL query that I can use to compare the data in A and B such that, I want to get delivery status of numbers in table B from table A. If a number is appearing in the table A and B then I get the delivery status of that number.
I am using this SQL query:
SELECT address, delivery_status FROM safaricom_receipt
WHERE address IN (SELECT mobile FROM saf_dispute);
This will work for you :
SELECT address, delivery_status
FROM safaricom_receipt
INNER JOIN saf_dispute
ON safaricom_receipt.address=saf_dispute.mobile;
Assuming you are using SQL Server; this should work for you
SELECT sd.mobile, sr.delivery_status
FROM saf_dispute sd with (nolock)
LEFT OUTER JOIN safaricom_receipt sr with (nolock) on sd.mobile=sr.address
where sr.delivery_status is NOT NULL
you would get duplicate rows if you are storing multiple rows for the same mobile number in any table. I would suggest adding a datetime column in the future
I have two separate tables in my access database, which both use a third table as the reference for one particular field on each table. The data is entered onto the different tables by separate forms. Then I have several queries that then reference those particular fields that count and show unique values. Those queries show the actual values, then I created an sql query that does the same thing, only it shows the reference ID instead of the value in the actual field.
table ODI----------table CDN----------reference table
id RHA---------id CHA----------------id HA
1 blank----------1 radio---------------1 internet
2 internet-------2 tv------------------2 radio
3 referral-------3 radio---------------3 referral
4 tv-------------4 blank---------------4 repeat customer
5 blank----------5 internet------------5 tv
6 internet-------6 referral------------6 employee
7 referral-------7 referral------------7 social media
this is the code I am trying to make work.
SELECT m.[Marketing Results], Count(*) AS [Count]
FROM (SELECT RHA as [Marketing Results] FROM ODI
UNION ALL
SELECT CHA as [Marketing Results] FROM CDN) AS m
GROUP BY m.[Marketing Results]
HAVING (((m.[Marketing Results]) Is Not Null))
ORDER BY Count(*) DESC;
and what my desired result is,
Marketing Results--Counts
referral------------------4
internet------------------3
radio---------------------2
tv------------------------2
Lookup fields with alias don't show what is actually stored in table. ID is stored, not descriptive alias. Lookup alias will carry into regular queries but Union query only pulls actual stored values. At some point need to include reference table in query by joining on key fields in order to retrieve descriptive alias. Options:
in each UNION query SELECT line, join tables
join UNION query to reference table
join aggregate query to reference table
Most experienced developers will not build lookups in table because of confusion they cause. Also, they are not portable to other database platforms. http://access.mvps.org/Access/lookupfields.htm
I am working on ABAP program - user input is to query column ANLAGE and output is to get all records from table EADZ (and only fields of EADZ) based on ANLAGE.
Statement and joins should work like this:
Input ANLAGE, find in table EASTL, gets LOGIKNR
Input LOGIKNR, find in table EGERR, gets EQUNR
Input EQUNR, find in table ETDZ, gets LOGIKZW
Input LOGIKZW, find in table EADZ, gets all records (this is the final output)
Here is the code I tried:
DATA: gt_cas_rezy TYPE STANDARD TABLE OF eadz,
lv_dummy_eanl LIKE eanl-anlage.
SELECT-OPTIONS: so_anl FOR lv_dummy_eanl NO INTERVALS NO-EXTENSION.
SELECT * FROM eadz
INNER JOIN etdz ON eadz~logikzw EQ etdz~logikzw
INNER JOIN egerr ON etdz~equnr EQ egerr~equnr
INNER JOIN eastl ON egerr~logiknr EQ eastl~logiknr
INTO CORRESPONDING FIELDS OF TABLE #gt_cas_rezy
WHERE eastl~anlage IN #so_anl.
I got the records from table EADZ except that the date fields are empty (even though, they are filled in database table). I am assuming there is a problem with JOINs since in statement like this I join all the fields of all 4 tables into one "record" and then to corresponding fields of internal table.
How to get the values of date fields?
You can find the answer in the documentation.
If a column name appears multiple times and no alternative column name was granted, the last column listed is assigned.
In your case, at least two tables share the same column name. Therefore the values from the last mentioned table are used in the join.
You can solve this by listing the columns explicitly (or eadz~* in your case), giving an alias if required.
SELECT EADZ~* FROM EADZ INNER JOIN ETDZ ON EADZ~LOGIKZW = ETDZ~LOGIKZW
INNER JOIN EGERR ON ETDZ~EQUNR = EGERR~EQUNR
INNER JOIN EASTL ON EGERR~LOGIKNR = EASTL~LOGIKNR
INTO CORRESPONDING FIELDS OF TABLE #gt_cas_rezy
WHERE EASTL~ANLAGE IN #SO_ANL.
If you require additional fields, you can add them explicily with e.g. EADZ~*, EASTL~A.
If I have table 1 called "FILES" and table 2 called "Networks" and the value that goes in FILES.Network_ID must be from a list defined in Networks.Network_ID
If I wanted to run a query to find out if there are any values under network_id in table 1 that are not defined in table 2, I tried the below which doesn't work apparently...Also, I'm using the SQL view of MS ACCESS
SELECT *
FROM (FILES f LEFT JOIN Networks
ON f.Network_ID <> Networks.Network_ID)
This query won't work properly because your are trying to join if the ids don't match, so ideally while making join the rows will match
For instance if table Files contains rows with network id 1,2,3 and table Networks contains network id 1,2 then upon joining you will get a combination of rows with network ids [1,2], [2,1],[3,1],[3,2].
Instance if you use a subquery and then filter it using IN clause will work
select * from files where network_id not in (select network_id from networks);
Try this
SELECT *
FROM (FILES f LEFT JOIN Networks
ON f.Network_ID =Networks.Network_ID)
Where Networks.Network_ID Is Null
To ensure data integrity create a relationship between both tables.
So I have three tables: companies, addresses and company_address.
For optimization reasons I need to copy city column from addresses table to companies table. Relation between companies and addresses is many to one (as many companies can occupy same address). They are connected through company_address table, consisting of address_id and company_id columns.
I found this solution for case without intermediate table: How to copy one column of a table into another table's column in PostgreSQL comparing same ID
Trying to modify query I came up with:
UPDATE company SET company.city=foo.city
FROM (
SELECT company_address.company_id, company_address.address_id, address.city
FROM address LEFT JOIN company_address
ON address.id=company_address.address_id
) foo
WHERE company.id=foo.company_id;
but it gives error:
ERROR: column "company" of relation "company" does not exist
I cant figure out what is going on. I'll be grateful for any ideas.
You don't need a subquery for that. Also, refer in the SET clause to your table columns without preceding with table name.
I believe that since your WHERE condition includes joined table, it should be INNER JOIN instead of a LEFT JOIN.
UPDATE company c
SET city = a.city
FROM address a
INNER JOIN company_address ca ON a.id = ca.address_id
WHERE c.id = ca.company_id
Note how using aliases for table names shortens the code and makes it readable at the very first glance.
You're right syntactically, you just don't need the table name at the beginning of the update statement:
UPDATE company SET city=foo.city
FROM (
SELECT company_address.company_id, company_address.address_id, address.city
FROM address LEFT JOIN company_address
ON address.id=company_address.address_id
) foo
WHERE company.id=foo.company_id;
