There is a table in SQl database which shows the result the way below:
ID Name value
1 Chips 100
2 Chocolate 50
3 Ice Cream 200
4 Burger 40
but I want to display it like in this way:
Name value
Chocolate 50
Chips 100
Ice Cream 200
Burger 40
how can I do this in sql server?
You can use ID to do the sorting like below
ORDER BY CASE ID
WHEN 2 THEN 1
WHEN 1 THEN 2
WHEN 3 THEN 3
WHEN 4 THEN 4
ELSE 5
END
If there is dynamic rows (lot of rows), you can use same like below
ORDER BY CASE ID
WHEN 2 THEN 1
ELSE 2
END
The else part will take care of the rest of the rows.
You can use CASE in ORDER BY to make sure the record with name = 'Chocolate' comes first and the rest is sorted by ID.
select name, value
from table1
order by case name
when 'Chocolate' then -1
else ID
end
Try this
SELECT * FROM `test` WHERE 1 ORDER BY name = 'Chocolate' DESC

I need to combine all values by one column depends on the key from another column. Can someone help me to get out of this problem please?
here is the short example of my problem.
CUST_ID CUST_REL_ID
100 1
100 2
100 3
100 4
200 5
200 6
200 7
CUST_ID CUST_REL_ID
1 1
1 2
1 3
1 4
2 1
2 2
2 3
2 4
...
5 5
5 6
5 7
I think you just want a self-join:
select t1.cust_rel_id, t2.cust_rel_id
from t t1 join
t t2
on t1.cust_id = t2.cust_id
order by t1.cust_rel_id, t2.cust_rel_id;
I don't understand your naming conventions. The column called cust_id in the result set looks nothing like the column called cust_id in the source data. But this appears to be what you want to do.
I'm attempting to have a function or view that is able to calculate and roll up various counts while being able to search on a many to many affiliation.
Here is an example data set:
Invoice Table:
InvoiceID LocationID StatusID
1 5 1
2 5 1
3 5 1
4 5 2
5 7 2
5 7 1
5 7 2
Group Table:
GroupID GroupName
1 Group 1
2 Group 2
GroupToLocation Table:
GroupToLocationID GroupID LocationID
1 1 5
2 2 5
3 2 7
I have gotten to the point where I could sum up the various statuses per location and get this:
LocationID Status1 Status2
5 3 1
7 1 2
Location 5 has 3 Invoices with a status of 1, and 1 invoice with a status of 2 while Location 7 has 1 status 1 and 2 status 2
There are two groups, and Location 5 is in both, while Location 7 is only in the second. I need to be able to set it up where I can append a where statement like this:
select * from vw_GroupCounts
where GroupName = 'Group 2'
or
select Invoice, SUM(*) from vw_GroupCounts
where GroupName = 'Group 2'
And that result in only getting Location 7. Whenever I do this, as I have to use left joins or something along those lines, the counts are duplicating for each group the the Location is affiliated with. I know I could do something along the lines of a subquery and pass in the GroupName into that, but the system I am working with uses a dynamic query builder that appends WHERE statements based on user input.
I don't mind using view, or functions, or any number of functions inside of functions, but I hope there is a way to do what I'm looking for.
Since locations 5 and 7 are in Group 2, if you search for group 2 in the where clause after joining all the tables, then you would get all records in this case, this isn't duplication, just the way the data is. A different join wouldn't change this, only changing the data. Let me know if I am misunderstanding something though.
Here is how you would join them to do that search.
Here it is with your first example of the location and status count.
I have table with up to 50 rows... like given below.
ID menu dispOdr ParntID
---------------------
1 abc 1 0
2 cde 2 0
3 fgh 1 2
4 ghdfdj 2 2
5 tetss 1 1
6 uni 3 0
but I want to be sorted
Like
ID menu dispOdr ParntID
---------------------
1 abc 1 0
5 tetss 1 1
2 cde 2 0
3 fgh 1 2
4 ghdfdj 2 2
6 uni 3 0
If have any query please let me know.. thanks in advance.
I am using sql server 2014
I think you need your current vs. desired output reversed. You say you want the menu column sorted, but it appears that it already is.
So assuming you are actually starting with the second table, you can sort the menu column simply using ORDER BY:
SELECT *
FROM mytable
ORDER BY menu ASC
I think that the query below produces the required output:
SELECT t1.ID, t1.menu, t1.dispOdr, t1.ParntID
FROM mytable AS t1
LEFT JOIN mytable AS t2 ON t1.ParntID = t2.ID
ORDER BY CASE
WHEN t1.ParntID = 0 THEN t1.dispOdr
ELSE t2.dispOdr
END,
CASE
WHEN t1.ParntID = 0 THEN 1
ELSE 2
END,
t1.dispOdr
The first CASE expression groups records according to the dispOdr of their parent. The second CASE places parent on the top of its subgroup. Finally, the last expression used in the ORDER BY clause orders all child records within a subgroup.
Note: The above query works with one level of nesting.
Lets say i have a table named 'Test' with these columns and values
ID Apple Pear Pineapple Orange
1 2 3 4 4
2 1 12 1 0
Now I want to make a SELECT statement to return all the rows where there is a value of 4 in any column.
I could do it like this, but I have many columns to check, so I need to find a other way to do this.
SELECT * FROM Test
WHERE test.apple = 4 or test.apple = 4 or test.pineapple = 4 or test.pineapple = 4
Try this:
SELECT *
FROM Test
WHERE 4 IN (Apple, Pear, Pineapple, Orange)
One method is to use in:
select t.*
from test t
where 4 in (t.apple, t.pear, t.pineapple, t.orange);
You still need to list the columns, but they just go in the in list.
I currently have a table in SQL that looks like this
PRODUCT_ID_1 PRODUCT_ID_2 SCORE
1 2 10
1 3 100
1 10 3000
2 10 10
3 35 100
3 2 1001
That is, PRODUCT_ID_1,PRODUCT_ID_2 is a primary key for this table.
What I would like to do is use this table to add in a row to tell whether or not the current row is the one that maximizes SCORE for a value of PRODUCT_ID_1.
In other words, what I would like to get is the following table:
PRODUCT_ID_1 PRODUCT_ID_2 SCORE IS_MAX_SCORE_FOR_ID_1
1 2 10 0
1 3 100 0
1 10 3000 1
2 10 10 1
3 35 100 0
3 2 1001 1
I am wondering how I can compute the IS_MAX_SCORE_FOR_ID_1 column and insert it into the table without having to create a new table.
You can try like this...
Select PRODUCT_ID_1, PRODUCT_ID_2 ,SCORE,
(Case when b.Score=
(Select Max(a.Score) from TableName a where a.PRODUCT_ID_1=b. PRODUCT_ID_1)
then 1 else 0 End) as IS_MAX_SCORE_FOR_ID_1
from TableName b
You can use a window function for this:
select product_id_1,
product_id_2,
score,
case
when score = max(score) over (partition by product_id_1) then 1
else 0
end as is_max_score_for_id_1
from the_table
order by product_id_1;
(The above is ANSI SQL and should run on any modern DBMS)
