I have currently managed to pull out a list of codes from some descriptions of which all should be formatted similarly for example:
'%[0-9][0-9][0-9][0-9][0-9]-[0-9][0-9][0-9][0-9]%'
(00000-0000)
'%[0-9][0-9][0-9][0-9]-[0-9][0-9][0-9][0-9]%'
(0000-0000)
'%[0-9][0-9][0-9][0-9][0-9]-[0-9][0-9][0-9]%'
(00000-000)
'%[0-9][0-9][0-9][0-9]-[0-9][0-9][0-9]%'
(0000-000)
'%[0-9][0-9][0-9][0-9]-[0-9][0-9]%'
(0000-00)
I have noticed the codes I have not currently pulled out as formatted as 00000000 and was wondering say if I were to pull these codes out if there was a way to restructure them to 00000-000?
The code I am currently using is as such based on the suggestion from Larnu yesterday if anybody could help with this String manipulation question would be greatly appreciated, If possible I would like to place the restructured string in the column with the others in the correct format.

This method actually work, despite what I had said. The data I ran this query against was inconsistent and the code matched values where possible, although I had had to expand the search to look for a couple more varieties of Character structures.

I need to make hierarchical queries, and I need to get the results of CONNECT_BY_ISCYCLE and CONNECT_BY_ISLEAF, but these features are supported in Oracle not in Snowflake.
What are the alternative ways to implement the functionalities of CONNECT_BY_ISCYCLE and CONNECT_BY_ISLEAF in snowflake without using them as these keywords are not supported there?
Wonder if you have taken a look at the following Snowflake features?
https://docs.snowflake.net/manuals/user-guide/queries-hierarchical.html#using-connect-by-or-recursive-ctes-to-query-hierarchical-data
Yes I took a look there. I also took a look at https://docs.snowflake.net/manuals/sql-reference/constructs/connect-by.html where it clearly says that these features are not supported in Snowflake.
I was trying below code block to find an alternative but facing varieties of error in snowflake.

select
emp_number,
user_id
from person
),
person_edges as (
select
supervisor_emp_number,

),
select
pv.emp_number emp_id_pk,

CONNECT_BY_ROOT pv.emp_number AS root,
concat(SYS_CONNECT_BY_PATH(pv.emp_number,':'),':') as path,
-- CONNECT_BY_ISCYCLE AS iscyclic, ------------------- no idea how to implement this
-- CONNECT_BY_ISLEAF as isleaf ------------------- i tried below block, but it is not working
case
when (pe.supervisor_emp_number in (select emp_number from pv)) then 0
else 1
end AS isleaf
from person_vertex pv
left join person_edges pe on pv.emp_number = pe.emp_number
connect by prior A.emp_number = A.supervisor_emp_number
start with A.supervisor_emp_number is null
Any help with this block is really appreciated.
Thanks.

I'm trying to build a query in MS Access and having an issue figuring out the best way to build it. What I'm trying to do is is make sure all the Higher retails match within a set of matching pack numbers. For example:
PackNum Prefix Retail
6451618 DF 37.99
6451618 SK 37.99
6451618 VJ 34.99
6451618 SG 37.99
One of the group is off and I want the query to show it.
I was attempting to use something like this to have check but I'm not getting the results I'm looking for
IIf([dbo_PIC704Current]![PackNum]=[dbo_PIC704Current]![PackNum]
And [dbo_PIC704Current]![Ret2]<>[dbo_PIC704Current]![Ret2],True,False)
Any help or push in the right direction would be greatly appreciated!
-Deke
SELECT dbo_pic704current.packnum
, Min(dbo_pic704current.Ret2) AS LowRet2
, Max(dbo_pic704current.Ret2) AS HighRet2
, dbo_CatalogInfo.MediaId
, dbo_pic704current.DiscountReasonCode
, dbo_CatalogInfo.Brand
FROM dbo_pic704current INNER JOIN dbo_CatalogInfo ON (dbo_pic704current.year =
dbo_CatalogInfo.mailyear) AND (dbo_pic704current.catid = dbo_CatalogInfo.catalog)
WHERE (((dbo_CatalogInfo.MediaId)='CAT Catalog'))
GROUP BY dbo_pic704current.packnum, dbo_CatalogInfo.MediaId,
dbo_pic704current.DiscountReasonCode, dbo_CatalogInfo.Brand, dbo_pic704current.Year
HAVING (((Min(dbo_pic704current.Ret2))<>Max([Ret2])))
ORDER BY dbo_pic704current.packnum;
Your existing solution using aggregation is likely to yield better performance, but to offer an alternative, here is an example using a correlated subquery:
select
pc.packnum, pc.ret2, ci.mediaid, pc.discountreasoncode, ci.brand
from
dbo_pic704current pc inner join dbo_cataloginfo ci on
pc.year = ci.mailyear and pc.catid = ci.catalog
where
ci.mediaid = 'cat catalog' and exists
(select 1 from dbo_pic704current t where t.packnum = pc.packnum and t.ret2 > pc.ret2)
order by
pc.packnum
I am using Codename One to get data from a database and display it in a table.
This is functioning quite well, and now I am trying to add a feature that limits the number of items that are shown in the table. To get there, I want to retrieve a selected number of columns from the database .
Unfortunately, common java sql operations do not seem to work. Below is what I have so far. All approaches don't throw any errors, but also also don't display the desired range or ranges. Another way to obtain a selection would probably be an ArrayList, but I would very much like to stick with a direct approach, since this appears to be relatively easy and elegant solution.
db = display.getInstance().openOrCreate("MyDB.db");
db.execute("CREATE TABLE IF NOT EXISTS Termine (Date NOT NULL,Event NOT NULL, Date_String NOT NULL)");
// prints the entire number of items from the database
cur = db.executeQuery("select * from (select * from Termine order by Date) where Date >= 5;");
// doesn't print anything
cur = db.executeQuery("SELECT * from ( select m.*, Date r from Termine m ) where r > 4 and r < 10;");
// doesn't print anything
cur = db.executeQuery("SELECT * from ( select m.*, Date r from Termine m ) where r BETWEEN 5 AND 10;");
while (cur.next()) {
Row currentRow = cur.getRow();
String event = currentRow.getString(1);
System.out.println(event);
}
Is my approach feasible? Any help would be greatly appreciated.
You can use the LIMIT SQL keyword as explained here.
SELECT column_list FROM table LIMIT row_count OFFSET offset;
A good practice is to search for "sqlite" and the SQL feature you are looking for as mobile SQL databases on all platforms are based on sqlite which has some quirks.
I have string data in the following format:
MODELNUMBER=Z12345&HELLOWORLD=WY554&GADTYPE=PLA&ID=Z-12345
/DTYPE=PLA&ID=S-10758&UN_JTT_REDIRECT=UN_JTT_IOSV
and need to extract IDs based on two conditions
Starting after a pattern &ID=
Ending till the last character or
if it hits a & stop right there.
So in the above example I'm using the following code:
SUBSTRING(MyCol,(PATINDEX('%&id=%',[MyCol])+4),(LEN(MyCol) - PATINDEX('%&id%',[MyCol])))
Essentially looking the pattern &id=% and extract string after that till end of the line. Would anyone advise on how to handle the later part of the logic ..
My current results are
Z-12345
Z-12345&UN_JTT_REDIRECT=UN_JTT_IOSV
What I need is
Z-12345
Z-12345
Try this
SUBSTRING(MyCol, (PATINDEX('%[A-Z]-[0-9][0-9][0-9][0-9][0-9]%',[MyCol])),7)
if you run into performance issues add the where clause below
-- from Mytable
WHERE [MyCol] like '%[A-Z]-[0-9][0-9][0-9][0-9][0-9]%'
maybe not the most elegant solution but it works for me.
Correct syntax of PATINDEX
Here's one example how to do it:
select
substring(d.data, s.s, isnull(nullif(e.e,0),2000)-s.s) as ID,
d.data
from data d
cross apply (
select charindex('&ID=', d.data)+4 as s
) s
cross apply (
select charindex('&', d.data, s) as e
) e
where s.s > 4
This assumes there data column is varchar(2000) and the where clause leaves out any rows that don't have &ID=
The first cross apply searches for the start position, the second one for the end. The isnull+nulliff in the actual select handles the case where & is not found and replaces it with 2000 to make sure the whole string is returned.
Would it be possible to alias an expression returned by a SELECT statement in order to refer to it in other parts of this same SELECT as if it would be a column among others ?
A kind of "temporary variable" whose scope would be limited to the SELECT statement, a little bit like the WITH clause before a SELECT to use a temporary named recorset.
A naive sample of what I'd like to achieve :
SELECT
FIRSTNAME + ' ' + NAME AS FULLNAME,
CASE WHEN LEN(FULLNAME)>3 THEN 1 ELSE 0 END AS ISCORRECT
FROM USERS
where FULLNAME could be used to determine the subsequent output field ISCORRECT, though not being a real column of the table USERS... instead of this laboured error-prone (but working) copy/paste :
SELECT
FIRSTNAME + ' ' + NAME AS FULLNAME,
CASE WHEN LEN(FIRSTNAME + ' ' + NAME)>3 THEN 1 ELSE 0 END AS ISCORRECT
FROM USERS
This sample well describes what I want, but I can easily imagine similar needs where FULLNAME might also be used in other parts of the SELECT statement : in a JOIN, in the WHERE, in a GROUP BY, ORDER BY, etc.
PS : I use SQL Server 2005 but would be also interested in any 2008-specific answer.
Thanks a lot ! :-)
Edit :
In spite of my high respect towards those of you proposing to use a side- or inner-query, I don't feel at ease with such possibilities. My sample really is a naive one. The true queries are rather with 30 output fields including complex expressions (including calls to CLR functions), 15 inner/left outer joins, and 20 additionnal where criteria. I suspect I had rather not multiplying to many indirections towards co-queries if I can avoid it.
I believe you would have to put it in an inner query, and then be able to refer to it outside of the query.
Simplest example based on yours:
select a.fullname, case when len(a.fullname) > 3 then 1
else 0 end as incorrect
from (select firstname + ' ' + name as fullname
from users) a
Example with a CTE
;with names (FULLNAME) as (
SELECT FIRSTNAME + ' ' + NAME
FROM USERS
) select
FULLNAME,
CASE WHEN LEN(FULLNAME) > 3 THEN 1 ELSE 0 END AS ISCORRECT
FROM names
You can use cross apply to concatenate strings or do calculations etc.. that involves just the current row.
select T.fullname,
case when len(T.fullname) > 3
then 1
else 0
end iscorrect
from users as U
cross apply
(select U.firstname+' '+U.name) as T(fullname)
order by T.fullname
Though not very satisfied with it, I choose (temporarily ?) a third option : I avoid co-queries and copy/pasting my complex hard-to-read expression (here symbolized by the simple one aliased as FULLNAME) by embeddind it in a scalar function... which is therefore called several times in different parts of my SELECT.
SELECT
dbo.GetFULLNAME(FIRSTNAME,NAME) AS FULLNAME,
CASE WHEN LEN(dbo.GetFULLNAME(FIRSTNAME,NAME))>3 THEN 1 ELSE 0 END AS ISCORRECT
FROM USERS
What do you think of it ?
(I precise that though more complex and unreadable than in my OP, the real expression remains a "simple" matter of string manipulation using several input fields, and doesn't involve any sub-querying or anything like that).
