I am having data like:
ItemCode Attribute PositionID
ITEM-000032 CHESTSIZE 1
ITEM-000032 JACKETLEN 2
ITEM-000042 CHESTSIZE 1
ITEM-000042 JACKETLEN 2
**ITEM-000049 SLACKWAIST 1**
ITEM-000071 CHESTSIZE 1
ITEM-000071 JACKETLEN 2
ITEM-000074 CHESTSIZE 1
ITEM-000074 JACKETLEN 2
In above data except ITEM-000049 others are having perfect combination. so i want to create a new row for ITEM-000049
As
ITEM-000049 -- 2
to make it perfect.
Kind regards,

Sounds like for each ItemCode, you are expecting 2 records, for 2 different Attributes.
So something like this is what I think you're after. Just run the SELECT part of it first without the INSERT to check it is indeed what you're after.
INSERT YourTable (ItemCode, Attribute, PositionID)
SELECT t.ItemCode, 'SECOND ATTRIBUTE', 2
FROM
(
SELECT ItemCode
FROM YourTable
GROUP BY ItemCode
HAVING COUNT(*) = 1
) t

How to repeat rows based on column value in snowflake using sql.
I tried a few methods but not working such as dual and connect by.
I have two columns: Id and Quantity.
For each ID, there are different values of Quantity.
So if you have a count, you can use a generator:
with ten_rows as (
select row_number() over (order by null) as rn
from table(generator(ROWCOUNT=>10))
), data(id, count) as (
select * from values
(1,2),
(2,4)
)
SELECT
d.*
,r.rn
from data as d
join ten_rows as r
on d.count >= r.rn
order by 1,3;
ID
COUNT

Ok let's start by generating some data. We will create 10 rows, with a QTY. The QTY will be randomly chosen as 1 or 2.
Next we want to duplicate the rows with a QTY of 2 and leave the QTY =1 as they are.
Obviously you can change all parameters above to suit your needs - this solution works super fast and in my opinion way better than table generation.
Simply stack SPLIT_TO_TABLE(), REPEAT() with a LATERAL() join and voila.
WITH TEN_ROWS AS (SELECT ROW_NUMBER()OVER(ORDER BY NULL)SOME_ID,UNIFORM(1,2,RANDOM())QTY FROM TABLE(GENERATOR(ROWCOUNT=>10)))
SELECT
TEN_ROWS.*
FROM
TEN_ROWS,LATERAL SPLIT_TO_TABLE(REPEAT('hire me $10/hour',QTY-1),'hire me $10/hour')ALTERNATIVE_APPROACH;
I am pretty new to SQL and I thought I was comfortable using it after a while but it still is tough. I am trying to increment ids. I know I could use auto-increment but in this case there are id has relationship with several categories so it has to start with different numbers so I can't do it.
The table looks something like this:
id category
----------------
1000 1
1000 1
...
2000 2
2000 2
...
And I want to make it:
id category
------------------
1000 1
1001 1
1002 1
...
2000 2
2001 2
...
I tried:
UPDATE T1
SET id = CASE
WHEN EXISTS (SELECT id FROM STYLE WHERE T1.id = id)
THEN (SELECT MAX(CAST(id AS INT)) + 1
FROM STYLE
WHERE category = T1.category)
END
FROM STYLE T1
WHERE idStyle = idStyle
But it just added 1 to all rows. How could I go 1 by 1 so it could actually get the incremented max id? Thank you.
In the absense of real sample data, this is a pseudo-sql, however, something like...
UPDATE YT
----SELECT NULL as Ihave no context of other fields in your table
SET id = id + ROW_NUMBER() OVER (PARTITION BY category ORDER BY (SELECT NULL)) - 1
FROM YourTable YT;
You can use row_number() function instead :
select *,
concat(cid, row_number() over (partition by id order by category)-1) as NewId
from style s;
I want to setup a simple query that will filter out any row that contains "A" in the ItemID, but my issue is I also do NOT want to display any journal ID from a different row since it matched "A". I tried googling the solution, but I am sure I am not using the right keywords to find it. I am using microsoft sql 2008, but I am not a database admin so I am not to familiar. I tried using distinct, and I also tried group by, but in this situation it does not work.
This is a simplified version of the table that I am working with:
JournalID ItemID PrimaryKEY
1 A 1
1 B 2
2 A 3
2 C 4
3 B 5
4 D 6
And here is how I would like to make it look:
JournalID ItemID PrimaryKEY
3 B 5
4 D 6
This will exclude any rows where the ItemID is 'A' and also any rows that have the same JournalID as a row where a ItemID was 'A'.
SELECT JournalID, ItemID, PrimaryKEY
FROM TABLE
WHERE JournalID NOT IN (Select JournalID FROM TABLE WHERE ItemID = 'A')
Try this:
SELECT *
FROM table_name
WHERE JournalID
NOT IN (SELECT JournalID
FROM table_name
WHERE ItemID = 'A')
How to fetch the rows from the top 2 pack id's not at a all of the rows in SQL Server?
Ex: Sample_table
tranid packid referencenum
1 1 123456
2 1 654982
3 2 894652
4 3 684521
5 3 684651
6 4 987566
Based on above sample table, how do I get the rows of pack 2 (for 1 and 2) for next instance I need again 3 and 4 rows
Can anyone help me out to sort the issue?
If I didn't miss something, this:
SELECT *
FROM PacksTable p
WHERE p.Id IN (1, 2)
Will give you only the data for the two pack_id's in your table.
It is unclear what you are looking for here. You can group by pack_id then get the top two pack_id, but what do you want to do with the grouped referencenum values for grouped pack_id, i.e What aggregate function you will use for this column, Min, Max, etc ??!.
In other words: If you are looking for the Top minimum pack_id, i.e.: 1, 2 in the first time, you will have to answer the question: What aggregate function to use with the corresponding referencenum values??,
For example, you can use MIN like this:
SELECT TOP(2) p.packid, MIN(p.referencenum)
FROM PacksTable p
GROUP BY(p.packid)
ORDER BY p.packid
please go through the following query.
select * from sample_table group by packid;
You could use variables combined with the DENSE_RANK function to window through two packid's at a time:
create table #packing (tranid int,packid int,referencenum int)
insert into #packing values
(1,1,123456)
, (2,1,654982)
, (3,2,894652)
, (4,3,684521)
, (5,3,684651)
, (6,4,987566)
go
declare #i int=-1;
declare #j int=0;
while ##ROWCOUNT>0 begin
set #i+=2;
set #j+=2;
; with a as (
select *, dr=dense_rank()over(order by packid) from #packing
)
select tranid, packid, referencenum
from a
where dr between #i and #j;
end
go
drop table #packing
go

This is the opposite of reducing repeating records.
SQL query to create physical inventory checklists
If widget-xyz has a qty of 1 item return 1 row, but if it has 5, return 5 rows etc.
For all widgets in a particular warehouse.
Previously this was handled with a macro working through a range in excel, checking the qty column. Is there a way to make a single query instead?
The tables are FoxPro dbf files generated by an application and I am outputting this into html
Instead of generating an xml string and using xml parsing functions to generate a counter as Nestor has suggested, you might consider joining on a recursive CTE as a counter, as LukLed has hinted to:
WITH Counter AS
(
SELECT 0 i
UNION ALL
SELECT i + 1
FROM Counter
WHERE i < 100
),
Data AS
(
SELECT 'A' sku, 1 qty
UNION
SELECT 'B', 2
UNION
SELECT 'C', 3
)
SELECT *
FROM Data
INNER JOIN Counter ON i < qty
According to query analyzer, this query is much faster than the xml pseudo-table. This approach also gives you a recordset with a natural key (sku, i).
There is a default recursion limit of 100 in MSSQL that will restrict your counter. If you have quantities > 100, you can either increase this limit, use nested counters, or create a physical table for counting.
For SQL 2005/2008, take a look at
CROSS APPLY
What I would do is CROSS APPLY each row with a sub table with as many rows as qty has. A secondary question is how to create that sub table (I'd suggest to create an xml string and then parse it with the xml operators)
I hope this gives you a starting pointer....
Starting with
declare #table table (sku int, qty int);
insert into #table values (1, 5), (2,4), (3,2);
select * from #table;
sku qty
----------- -----------
1 5
2 4
3 2
You can generate:
with MainT as (
select *, convert(xml,'<table>'+REPLICATE('<r></r>',qty)+'</table>') as pseudo_table
from #table
)
select p.sku, p.qty
from MainT p
CROSS APPLY
(
select p.sku from p.pseudo_table.nodes('/table/r') T(row)
) crossT
sku qty
----------- -----------
1 5
1 5
1 5
1 5
1 5
2 4
2 4
2 4
2 4
3 2
3 2
Is that what you want?
Seriously dude... next time put more effort writing your question. It's impossible to know exactly what you are looking for.
You can use table with number from 1 to max(quantity) and join your table by quantity <= number. You can do it in many ways, but it depends on sql engine.
You can do this using dynamic sql.
