I have a table with 3 columns id, homeph, mobileph.
If homeph is equal to mobileph, then homeph or mobileph with other line what is query for this?
This should give you the desired result.
SELECT ID AS id, Homeph AS phone
FROM table
UNION
SELECT ID AS id, Contactph AS phone
FROM table
In Oracle, you could use:
SELECT DISTINCT id, phone
FROM input_table
UNPIVOT (
phone FOR type IN (homeph, contactph)
)
But it will be more efficient to check if the phone numbers are identical before unpivoting (as UNPIVOT will, by default, ignore NULL values):
SELECT id, phone
FROM (
SELECT id,
homeph,
CASE WHEN homeph = contactph THEN NULL ELSE contactph END AS contactph
FROM input_table
)
UNPIVOT (
phone FOR type IN (homeph, contactph)
)
Which, for the sample data:
CREATE TABLE input_table (id, homeph, contactph ) AS
SELECT 1, 99999, 88888 FROM DUAL UNION ALL
SELECT 2, 77777, 77777 FROM DUAL;
Both output:
ID
PHONE
1
99999
1
88888
2
77777

I have JSON data in a column in my table. I am trying to apply where condition on the JSON column and fetch records.
Employee table:
Here is my SQL query:
SELECT ID, EMP_NAME
FROM EMPLOYEE
WHERE JSON_VALUE(TEAM, '$') IN (2, 3, 4, 5, 7, 10)
I am getting an empty result when I use this query. Any help on how to do this?
You need to parse the JSON in the TEAM column with OPENJSON():
Table:
CREATE TABLE EMPLOYEE (
ID int,
EMP_NAME varchar(50),
TEAM varchar(1000)
)
INSERT INTO EMPLOYEE (ID, EMP_NAME, TEAM)
VALUES
(1, 'Name1', '[2,11]'),
(2, 'Name2', '[2,3,4,5,7,10]'),
(3, 'Name3', NULL)
Statement:
SELECT DISTINCT e.ID, e.EMP_NAME
FROM EMPLOYEE e
CROSS APPLY OPENJSON(e.TEAM) WITH (TEAM int '$') j
WHERE j.TEAM IN (2,3,4,5,7,10)
Result:
ID EMP_NAME
1 Name1
2 Name2
As an additional option, if you want to get the matches as an aggregated text, you may use the following statement (SQL Server 2017 is needed):
SELECT e.ID, e.EMP_NAME, a.TEAM
FROM EMPLOYEE e
CROSS APPLY (
SELECT STRING_AGG(TEAM, ',') AS TEAM
FROM OPENJSON(e.TEAM) WITH (TEAM int '$')
WHERE TEAM IN (2,3,4,5,7,10)
) a
WHERE a.TEAM IS NOT NULL
Result:
ID EMP_NAME TEAM
1 Name1 2
2 Name2 2,3,4,5,7,10
JSON_VALUE returns a scalar value, not a data set, which you appaer to think it would. If you run SELECT JSON_VALUE('[2,3,4,5,7,10]','$') you'll see that it returns NULL, so yes, no rows will be returned.
You need to treat the JSON like a data set, not a single value:
SELECT ID, EMP_NAME
FROM EMPLOYEE E
WHERE EXISTS (SELECT 1
FROM OPENJSON (E.TEAM) OJ
WHERE OJ.Value IN (2,3,4,5,7,10))
I have table as below.
Name Primary phone Primary Ind
Manju 11 Y
Manju 22 N
Tyagi 33 N
Tyagi 44 Y
And I want my result to be displayed like below based on the Primary Ind Flag in my table above. Basically if the primary indicator is "Y" Phone No should go to 'Primary Phone`. IF "N", it should go to "Non Primary"
Name Primary Phone Non Primary
manju 11 22
Tyagi 44 33
I need to achieve this using select and UNION. this is the assignment gave to me. Can somebody help how to do it?
A self join
select t1.name, t1.phone as primary, t2.phone as non
from table t1
join table t2
on t2.name = t1.name
and t1.ind = 'y'
and t2.ind = 'n'
Not the way I'd handle this but as it's the requirement:
Simply generate two sets of data one with Y one with N, union and get the max of each. That max assumes that each record only has 2 phone #'s (one each primary & non-Primary)
SELECT name
, max([Primary Phone]) as [Primary Phone]
, max([non Primary] as [Non Primary)
FROM (SELECT name, [Primary phone], null as [non Primary]
FROM TABLE
WHERE [Primary Ind] = 'Y'
UNION ALL
SELECT name, Null as [Primary Phone], [Primary Phone ]
FROM TABLE
WHERE [Primary Ind] = 'N') DT
GROUP BY name
Union vs union all depends on if you have duplicates you need to eliminate, if you know you don't union all is slightly faster.
Union is not necessary but still you need it ,
select name,primaryphone,nonprimary from (
select name,primaryphone
from
(
select name,primaryphone,'primary' PrimaryInd from yourtable where primaryind='Y'
union
select name,primaryphone,'non primary' from yourtable where primaryind='N'
) a
where primaryind='primary')a1 join
( select name as name1,primaryphone as nonprimary
from
(
select name,primaryphone,'primary' PrimaryInd from yourtable where primaryind='Y'
union
select name,primaryphone,'non primary' from yourtable where primaryind='N'
) a
where primaryind='non primary')a2
on a1.name=a2.name1

I'm trying to group a SELECT like you'd normally do - AND at the same time make a new "shared/aggregate group" adding that to the original result-set without a secondary SELECT and UNION.
The secondary SELECT and UNION is out of the question since the real use of this is with some very big tables, with a lot of joins, so it would be waay to slow. So the UNION way is definitely out of the question.
I've tried my best to illustrate this with the following simplified example:
BEGIN TRAN
CREATE TABLE #MyTable
(
id INT,
name VARCHAR(255)
)
INSERT INTO #MyTable VALUES (1,'cola');
INSERT INTO #MyTable VALUES (2,'cola');
INSERT INTO #MyTable VALUES (3,'cola');
INSERT INTO #MyTable VALUES (4,'fanta');
INSERT INTO #MyTable VALUES (5,'fanta');
INSERT INTO #MyTable VALUES (6,'fanta');
INSERT INTO #MyTable VALUES (7,'water');
INSERT INTO #MyTable VALUES (8,'water');
INSERT INTO #MyTable VALUES (9,'water');
INSERT INTO #MyTable VALUES (10,'cola');
INSERT INTO #MyTable VALUES (11,'cola');
SELECT
CASE
WHEN name = 'cola' OR name = 'fanta'
THEN 'soda'
ELSE
name
END as name,
COUNT(distinct id) as count
FROM #MyTable
GROUP BY name
ROLLBACK TRAN
Actual output:
soda 5
soda 3
water 3
Desired output:
cola 5
fanta 3
soda 8 <- this is the "shared/aggregate group"
water 3
As Panagiotis Kanavos correctly pointed out in the comment above, this can be done using ROLLUP:
BEGIN TRAN
CREATE TABLE #BeverageType
(
name VARCHAR(255)
)
INSERT INTO #BeverageType VALUES ('Soda');
INSERT INTO #BeverageType VALUES ('Other');
CREATE TABLE #UserBeverage
(
id INT,
name VARCHAR(255)
)
INSERT INTO #UserBeverage VALUES (1,'cola');
INSERT INTO #UserBeverage VALUES (2,'cola');
INSERT INTO #UserBeverage VALUES (3,'cola');
INSERT INTO #UserBeverage VALUES (1,'fanta'); -- <- NOTE: user 1 drinks both cola and fanta so the as intended the user is only counted 1 time in the ROLLUP 'Soda' group (7)
INSERT INTO #UserBeverage VALUES (5,'fanta');
INSERT INTO #UserBeverage VALUES (6,'fanta');
INSERT INTO #UserBeverage VALUES (7,'water');
INSERT INTO #UserBeverage VALUES (8,'water');
INSERT INTO #UserBeverage VALUES (9,'water');
INSERT INTO #UserBeverage VALUES (10,'cola');
INSERT INTO #UserBeverage VALUES (11,'cola');
SELECT ub.name, bt.name AS groupName, COUNT(distinct id) as uniqueUserCount
FROM #UserBeverage as ub
JOIN #BeverageType as bt
ON CASE
WHEN (ub.name = 'water')
THEN 'Other'
ELSE
'Soda'
END = bt.name
GROUP BY ROLLUP(bt.name, ub.name)
ROLLBACK TRAN
Outputs:
cola Soda 5
fanta Soda 3
water Other 3
NULL Other 3
NULL Soda 7
NULL NULL 10
You should repeat CASE statement everywhere.
SELECT
CASE WHEN name = 'cola' OR name = 'fanta'
THEN 'soda' ELSE name END as name,
COUNT((CASE WHEN name = 'cola' OR name = 'fanta'
THEN 'soda' ELSE name END)) as count
FROM #MyTable
GROUP BY CASE WHEN name = 'cola' OR name = 'fanta'
THEN 'soda' ELSE name END
+-------+-------+
| name | count |
+-------+-------+
| soda | 8 |
+-------+-------+
| water | 3 |
+-------+-------+
Can I suggest to use a subquery:
SELECT name, count(*) AS count
FROM (SELECT CASE WHEN name = 'cola' OR name = 'fanta'
THEN 'soda' ELSE name END as name
FROM #MyTable) x
GROUP BY name;
If you need the aggregate as well as the individual products, then an alternative may be to use a UNION and select the aggregates as a second query.
SELECT name, count(distinct id) as count
FROM #MyTable
GROUP BY name
UNION
SELECT 'SODA', COUNT(distinct id) as count
FROM #MyTable
WHERE name = 'cola' or name ='fanta'
You might also use Søren Høyer Kristensen's summary table to get the aggregate names if you need more groupings.
I do have following table
ID Name
1 Jagan Mohan Reddy868
2 Jagan Mohan Reddy869
3 Jagan Mohan Reddy
Name column size is VARCHAR(55).
Now for some other task we need to take only 10 varchar length i.e. VARCHAR(10).
My requirement is to check that after taking the only 10 bits length of Name column value for eg if i take Name value of ID 1 i.e. Jagan Mohan Reddy868 by SUBSTRING(Name, 0,11) if it equals with another row value. here in this case the final value of SUBSTRING(Jagan Mohan Reddy868, 0,11) is equal to Name value of ID 3 row whose Name is 'Jagan Mohan Reddy'. I need to make a list of those kind rows. Can somebody help me out on how can i achieve in SQL Server.
My main check is that the truncated values of my Name column should not match with any non truncated values of Name column. If so i need to get those records.
Assuming I understand the question, I think you are looking for something like this:
Create and populate sample data (Please save us this step in your future questions)
DECLARE #T as TABLE
(
Id int identity(1,1),
Name varchar(15)
)
INSERT INTO #T VALUES
('Hi, I am Zohar.'),
('Hi, I am Peled.'),
('Hi, I am Z'),
('I''m Zohar peled')
Use a cte with a self inner join to get the list of ids that match the first 10 chars:
;WITH cte as
(
SELECT T2.Id As Id1, T1.Id As Id2
FROM #T T1
INNER JOIN #T T2 ON LEFT(T1.Name, 10) = t2.Name AND T1.Id <> T2.Id
)
Select the records from the original table, inner joined with a union of the Id1 and Id2 from the cte:
SELECT T.Id, Name
FROM #T T
INNER JOIN
(
SELECT Id1 As Id
FROM CTE
UNION
SELECT Id2
FROM CTE
) U ON T.Id = U.Id
Results:
Id Name
----------- ---------------
1 Hi, I am Zohar.
3 Hi, I am Z
Try this
SELECT Id,Name
FROM(
SELECT *,ROW_NUMBER() OVER(PARTITION BY Name, LEFT(Name,11) ORDER BY ID) RN
FROM Tbale1 T
) Tmp
WHERE Tmp.RN = 1
loop over your column for all the values and put your substring() function inside this loop and I think in Sql index of string starts from 1 instead of 0. If you pass your string to charindex() like this
CHARINDEX('Y', 'Your String')
thus you will come to know whether it is starting from 0 or 1
and you can save your substring value as value of other column with length 10
I hope it will help you..
I think this should cover all the cases you are looking for.
-- Create Table
DECLARE #T as TABLE

Id int identity(1,1),

I have the following table that I have to work with.

Basically, it is a product that stores up to 10 barcodes for a product code (simplified example). At any time, any number of those 10 barcode fields might have a value.
I have another table that has a list of product code and barcode, and need to add these to the product barcode table.
I need to perform an update so that any of the barcodes in barcodes_to_import are appended to the product_barcode table, into the first non null barcode column.
