I have 2 tables, with the same exact fields and fields names. i am trying to inner join them but im having some difficulty determining how i can get my results in my desired format.
I know i can do select a.customer, a.id, a.date, a.line, a.product, b.customer, b.id, b.date, b.line, b.product but instead of having my A data and B data on the same row, id like for them to be on seperate rows.
I have 2 tables, with the same exact fields and fields names, i am trying to inner join them so that unique line becomes a row.
Table A:
|customer| id | Date | line | Product|
|--------|-----|---------|------|--------|
| 445678 | 123 | 1/1/22 | 10 | 88975 |
| 853652 | 456 | 1/10/22 | 5 | 55876 |
| 845689 | 789 | 1/25/22 | 1 | 45587 |
TABLE B:
|customer| id | Date | line | Product|
|--------|-----|---------|------|--------|
| 445678 | 489 | 1/1/22 | 1 | 87574 |
| 853652 | 853 | 1/10/22 | 12 | 45678 |
| 587435 | 157 | 2/12/22 | 3 | 25896 |
DESIRED RESULTS:
|customer| id | Date | line | Product|
|--------|-----|---------|------|--------|
| 445678 | 123 | 1/1/22 | 10 | 88975 |
| 445678 | 489 | 1/1/22 | 1 | 87574 |
| 853652 | 456 | 1/10/22 | 5 | 55876 |
| 853652 | 853 | 1/10/22 | 12 | 45678 |
my query:
select a.customer, a.id, a.date, a.line, a.product
from data1 a
inner join data2 b
on a.date = b.date
and a.customer = b.customer

I am working on a Store Procedure where I need to update records from from table 1 into table 2.
Table1: contains the following 4 columns
----------------------------------------------
| ID | TableName | ColumnName | Value |
----------------------------------------------
| 1 | [UserDetails] | [FinalScore] | 92 |
| 2 | [UserDetails] | [FinalScore] | 89 |
| 3 | [UserDetails] | [FinalScore] | 65 |
| 4 | [UserDetails] | [FinalScore] | 91 |
| 5 | [UserDetails] | [FinalScore] | 76 |
| 1 |[EmployeeDetail]| [ScoreData] | 0.91 |
----------------------------------------------
UserDetails table
-----------------------------------------------------------
| UserID | UserName | ContactNo | FinalScore |
-----------------------------------------------------------
| 1 | John G | +13288992342 | 0 |
| 2 | Leonard J | +14581232342 | 0 |
| 3 | Max R | +17123992342 | 0 |
| 4 | Robert H | +15688992122 | 0 |
| 5 | Jimmy L | +1328996782 | 0 |
-----------------------------------------------------------
Need to load all the data from table1 into the corresponding destination table for large amount of data (30,000 to 60,000) records.
Table1 contains the ID (from ID Column in table1) and FinalScore (from ColumnName Column in table1) in the destination table (from TableName Column in table1) where the value (from Value Column in table1) needs to be loaded.
End Result of UserDetails table after SP execution :
-----------------------------------------------------------
| UserID | UserName | ContactNo | FinalScore |
-----------------------------------------------------------
| 1 | John G | +13288992342 | 92 |
| 2 | Leonard J | +14581232342 | 89 |
| 3 | Max R | +17123992342 | 65 |
| 4 | Robert H | +15688992122 | 91 |
| 5 | Jimmy L | +1328996782 | 76 |
-----------------------------------------------------------
I am not sure how to load the data from "table1" into destination table (userdetails table) for bulk data as update query in a loop is taking very long time to complete.
It's not pivot what you're after but a simple join:
select
a.userid, a.contactno, b.finalscore
from UserDetails a
join table1 b on a.id = b.id
alternatively, if you want to update the old table without creating a new one, you can update join
SQL update query using joins
I have a table with a data as bellow :
+--------+----------+-------+------------+--------------+
| month | code | type | date | PersonID |
+--------+----------+-------+------------+--------------+
| 201501 | 178954 | 3 | 2014-12-3 | 10 |
| 201501 | 178954 | 3 | 2014-12-3 | 10 |
| 201501 | 178955 | 2 | 2014-12-13 | 10 |
| 201501 | 178955 | 2 | 2014-12-13 | 10 |
| 201501 | 178956 | 2 | 2014-12-11 | 10 |
| 201501 | 178958 | 1 | 2014-12-10 | 10 |
| 201501 | 178959 | 2 | 2014-12-12 | 15 |
| 201501 | 178959 | 2 | 2014-12-12 | 15 |
| 201501 | 178954 | 1 | 2014-12-11 | 13 |
| 201501 | 178954 | 1 | 2014-12-11 | 13 |
+--------+----------+-------+------------+--------------+
In my first 6 lines i have the same PersonID in the same Month What i want if i have the same personID in the same Month i want to select the person who have the type is 2 with the recent date in my case the output will be like as bellow:
+--------+--------+------+------------+----------+
| month | code | type| date | PersonID |
+--------+--------+------+------------+----------+
| 201501 | 178955 | 2 | 2014-12-13 | 10 |
| 201501 | 178959 | 2 | 2014-12-12 | 15 |
| 201501 | 178954 | 2 | 2014-12-11 | 13 |
+--------+--------+------+------------+----------+
Also if they are some duplicate rows i don't want to display it
They are any solution to that ?
Simply use GROUP BY:
https://msdn.microsoft.com/de-de/library/ms177673(v=sql.120).aspx
SELECT mont, code, ... FROM tabelname GROUP BY PersonID, date, ...
Note that you have to specifiy all columns in the group by.
SELECT DISTINCT A.month, A.code, A.type, B.date, B.PersonID FROM YourTable A
INNER JOIN (SELECT PersonID, MAX(date) as date FROM YourTable
GROUP BY PersonID) B
ON (A.PersonID = B.PersonID
AND A.date = B.date)
WHERE A.type = 2 ORDER BY B.date DESC, A.PersonID
Just in case you/others are still wondering.
I made a INNER JOIN in stored procedure, but I don't know what to put to my WHERE clause to filter those column with null values and only shows those rows who has not null on a particular column.
CREATE PROCEDURE [dbo].[25]
#param1 int
AS
SELECT c.Name, c.Age, c2.Name, c2.Country
FROM Cus C
INNER JOIN Cus2 C2 ON c.id = c2.id
WHERE c2.country is not null and c2.id = #param1
Order by c2.Country
RETURN 0
ID 1
+-----+----+---------+---------+
| QID | ID | Name | Country |
+-----+----+---------+---------+
| 1 | 1 | Null | PH |
| 2 | 1 | Null | CN |
| 3 | 1 | Japhet | USA |
| 4 | 1 | Abegail | UK |

+-----+----+---------+---------+
ID 2

I want when I choose any of the user in the C Table it will display the C child table data and remove the null name rows and remain the rows with not null name column.
Desired Result:
C Table (Parent)
+----+---------+-----+
| ID | Name | Age |
+----+---------+-----+
| 3 | Abegail | 31 |
+----+---------+-----+
C2 Table (Child)
+-----+----+----------+---------+
| QID | ID | Name | Country |
+-----+----+----------+---------+
| 1 | 3 | Gab | PH |
| 3 | 3 | Reynaldo | USA |
| 4 | 3 | Abegail | UK |

WHERE column IS NOT NULL is the syntax to filter out NULL values.
Solution 1: test not null value
Example:
WHERE yourcolumn IS NOT NULL
Solution 2: test comparaison value in your where clause (comparaison substract null values)
Examples:
WHERE yourcolumn = value
WHERE yourcolumn <> value
WHERE yourcolumn in ( value)
WHERE yourcolumn not in ( value)
WHERE yourcolumn between value1 and value2
WHERE yourcolumn not between value1 and value2
Hi friends i have small doubt in sql server
here i want data based on condition

how to write query in sql server
Table :emp
id |status |date(mm-dd-yy) |fdate(mm-dd-yy) |tdate(mm-dd-yy)
1 | S |03-16-11 | |
1 | b | | 03-15-11 |03-18-11
1 | s |03-17-11 | |
1 | b | | 04-20-12 |04-30-12
1 | S |04-20-12 | |
1 | s |04-10-12 | |
1 | s |10-01-14 | |
1 | b | |10-02-14 |10-25-14
2 | s |01-18-12 | |
2 | b | |01-18-12 |01-28-12
2 | b | |03-10-13 |03-24-13
2 | s |03-16-13 | |

2 | s |03-23-13 | |
2 | b | |04-20-13 |04-27-13
2 | s |07-01-14 | |
the table (status = s, id, date) compare it with status = b, same id number and date ( Date value from status s) with the date range of fdate and tdate .
if that data with in range then Billing yes other wise billing no
output like
id |status |date(mm-dd-yy) |fdate(mm-dd-yy) |tdate(mm-dd-yy) |Billing
1 | S |03-16-11 | | |yes
1 | s |03-17-11 | | |yes
1 | S |04-20-12 | | |yes
1 | s |04-10-12 | | |no
1 | s |10-01-14 | | |no
2 | s |01-18-12 | | |yes
2 | s |03-16-13 | | |yes
2 | s |03-10-13 | | |yes
2 | s |03-23-13 | | |yes
2 | s |07-01-14 | | |no
i tried query like below
select *
from ( select * from emp a where status ='s') a
inner join (select * from emp b where status='b') b
on a.pn=b.pn
where a.date<=b.date1 and a.date>=b.date2
its not give exactely result.
please tell me how to write query in sql server .
Try
select a.Id,
a.status,
a.date,
a.fdate,
a.tdate,
max(IsNull(case when a.date between b.fDate and b.tDate
then 'yes'
else 'no'
end, 'no')) Billing
from emp a
left join emp b
on a.Id=b.Id
where a.status ='s'
and b.status = 'b'
group by a.Id,
a.status,
a.date,
a.fdate,
a.tdate
Some questions/comments:
What are the fields: pn, date1 and date2?
date1 in your query is, I guess, bigger than date2
being a novice sql user:
I have a simple table storing some records over night daily. table:
Table: T1
+----+-----+----+-----------+------------+
| Id | A | AB | Value | Date |
+----+-----+----+-----------+------------+
| 1 | abc | I | -48936.08 | 2013-06-24 |
| 2 | def | A | 431266.19 | 2013-06-24 |
| 3 | xyz | I | -13523.90 | 2013-06-24 |
| 4 | abc | A | 13523.90 | 2013-06-23 |
| 5 | xyz | I | -13523.90 | 2013-06-23 |
| 6 | def | A | 13523.90 | 2013-06-22 |
| 7 | def | I | -13523.90 | 2013-06-22 |
+----+-----+----+-----------+------------+
I would like to get all values of columns A,AB, Value for the latest Date on Column A filtered on AB = I
basically the result should look like:
+----+-----+----+-----------+------------+
| Id | A | AB | Value | Date |
+----+-----+----+-----------+------------+
| 1 | abc | I | -48936.08 | 2013-06-24 |
| 3 | xyz | I | -13523.90 | 2013-06-24 |
| 7 | def | I | -13523.90 | 2013-06-22 |
+----+-----+----+-----------+------------+
I have tried to use inner join twice on the same table but failed to come up with correct result.
any help would be appreciated.
thanks :)
This will work with sqlserver 2005+
