Several weeks ago I made a post to get help with converting a comma delimited list of values into a format that it could be used as part of an IN clause in Oracle. Here is a link to the post.
Oracle invalid number in clause
The answer was to split up the list into an individual row for each value. Here's the answer that I ended up using.
SELECT trim(regexp_substr(str, '[^,]+', 1, LEVEL)) str
FROM ( SELECT '1,2,3,4' str FROM dual )
CONNECT BY instr(str, ',', 1, LEVEL - 1) > 0
Is there a way that I can do something similar in SQL Server without having to create a custom function? I noticed that there's a STRING_SPLIT function, but I don't seem to have access to that on this SQL Server.
Any advice you might have would be greatly appreciated. I've been trying to take a stab at this for the majority of the day.
String_split function is available in MS SQL Server starting from version 2016. If you use older version you can write a few lines of code which do the same.
declare #str varchar(100)='1,2,3,4' --initial string
;with cte as (--build xml from the string
select cast('<s>'+replace(#str,',','</s><s>')+'</s>' as xml) x
)
--receive rows
select t.v.value('.[1]','int') value
from cte cross apply cte.x.nodes('s') t(v)

I'm new to Microsoft SQL Server 2014. I run this SQL code:
SELECT TOP(10) 'DBSG' as seek_entity, *
FROM DBSG..PM00200
and get this result:
Next, I want to find out total line items for that entity with code below.
WITH vw_pm00200_all AS
(
SELECT TOP(10)
'DBSG' as seek_entity, *
FROM
DBSG..PM00200
)
SELECT
seek_entity,
COUNT(*) AS total
FROM
vw_pm00200_all
GROUP BY
1
Sadly, I get this error. I have no idea why it failed.
Msg 164, Level 15, State 1, Line 9
Each GROUP BY expression must contain at least one column that is not an outer reference.
Lastly, please advise is Microsoft SQL Server based on Transact-SQL?
It looks like you are running into this problem here: Each GROUP BY expression must contain at least one column that is not an outer reference
As the answer points out, grouping by a constant literal is pointless as it is the same for all results. Count(*) will return the same result as Count(*) with a GROUP BY.
If this is just test code and you plan on using a CASE statement (with different values) in place of the string literal, you may have better luck.
Yes, T-SQL is Microsoft SQL Server's flavor of SQL.
I am trying to extract individual dates from a varchar column in a SQL Server 2016 tablet that are stored comma separated and am not sure how to proceed. The data is setup like this:
article Consolidation_Order_Cut_Off_Final_Allocation
------------------ ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
011040 01/13/2021,03/10/2021
019099 01/13/2021,01/27/2021,02/24/2021,03/24/2021,04/28/2021,05/26/2021,06/23/2021,07/28/2021
019310 01/27/2021,02/03/2021,03/10/2021,04/14/2021,05/12/2021,06/09/2021,07/14/2021,08/11/2021
059611 01/13/2021
Ideally - I would have each date split out into a new row. I have seen a few similar questions that use very complex functions but those seem to be for SQL Server 2008. I have also found the new function STRING_SPLIT but that would seem to be table valued and thus have to come in the FROM. One thought I had was to declare a variable to hold this column and then use something like select * FROM string_split(#dates,','); however since there is more than one value in that list that returns an error. I am very new to the 2016 version of SQL Server and curious if anyone has ran into a way to solve this.
String_Split() is a table valued function, so you can call it with a CROSS APPLY
Example or dbFiddle
Select A.article
,B.Value
From YourTable A
Cross Apply string_split(Consolidation_Order_Cut_Off_Final_Allocation,',') B
Below is an Oracle script that I need to execute on an SQL Server.
SELECT
records.pr_id,
SUBSTR (REPLACE (REPLACE (XMLAGG (XMLELEMENT ("x", prad4.selection_value)
ORDER BY prad4.selection_value),'</x>'),'<x>',' ; '),4) as teva_role
FROM records
Thanks for the help,
Barry
I programmed in SQL for years in several environments and it is about 75% the same. So, the SQL statement should work as is, however the functions (REPLACE, SUBSTR) will be what you need to research and change.
Also, you get columns from prad4 without including it in the FROM statement which is a problem.
And, finally, your parentheses aren't balanced which, I would think, would be a problem in Oracle as well.
This is basically concatenating a set of strings with a delimiter. The common way to do this, is using FOR XML PATH('') which seems to be the equivalent of the combination of XMLELEMENT() in Oracle, but with a different syntax. You can also use XML functions to prevent change of certain characters not allowed in XML. The STUFF takes care of the SUBSTR() part of your code. For a more detailed explanation, you can read this article on Creating a comma-separated list.
The code should look similar to this:
SELECT records.pr_id,
STUFF(( SELECT ' ; ' + prad4.selection_value
FROM prad4
WHERE prad4.pr_id = records.pr_id
ORDER BY prad4.selection_value
FOR XML PATH(''), TYPE).value('./text()[1]', 'varchar(max)'), 1, 3, '')
FROM records;
Of course, with the improvements of SQL Server 2017, the code can be simplified to something like this:
SELECT records.pr_id,
STRING_AGG( selection_value, ' ; ') WITHIN GROUP (ORDER BY selection_value ASC)
FROM records;
I am converting Access query to SQL Server.
I want to convert below lines to SQL
1. Format (210.6, "Standard")
2. Format (210.6, "#,##0.00")
How do i convert it to SQL query.
I have tried with below, but still not able to find the solution.
For the first query, i found below solution, which is correct
1. CONVERT(varchar, CAST(tSRO.OutputF11 AS money), 1)
Now, for second query, i do not know what i have to do.
From SQL Server 2012+ you can use FORMAT:
SELECT FORMAT(210.6, '#,##0.00') -- 210.60
SELECT FORMAT(1210.6, '#,##0.00') -- 1,210.60
LiveDemo
SQL Server before 2012:
SELECT REPLACE(CONVERT(VARCHAR,CONVERT(MONEY, 1210.6),1),'.00','') -- 1,210.60

Warning:
This operation is pure for presentation layer and should be done in application.
In a SQL Server 2000 DB, I have a table which holds string representations of Oracle DB dates. They are formatted like "16-MAY-12". I need to convert these to datetime. I can not seem to find a conversion style number that matches, nor can I find a function that will allow me to specify the input format. Any ideas?
This seems to work for me:
SELECT CONVERT(DATETIME, '16-MAY-12');
You can also try using TO_CHAR() to convert the Oracle values to a more SQL Server-friendly format (best is YYYYMMDD) before pulling them out of the darker side.
Follow Aaron's advice and cast to string on the Oracle side and then did a check/recast on the MS SQL side. See example below:
;WITH SOURCE AS (
SELECT * FROM openquery(lnk,
'SELECT
TO_CHAR(OFFDATE , ''YYYY-MM-DD HH24:MI:SS'') AS OFFDATE,
FROM
ORACLE_SOURCE')),
SOURCE_TRANSFORM AS
(
SELECT
CASE
WHEN ISDATE(OFFDATE) = 1 THEN CAST(OFFDATE AS DATETIME)
ELSE NULL END AS OFFDATE
FROM
SOURCE
)
SELECT * FROM SOURCE_TRANSFORM
