Could you please help me with a query for the following requirements?
I have a list of Cities which I want to verify from a table. The query will have the Input List (below) in the where clause and gives me results like shown below in expected result.
Input list = ('City1','City2','City3','City4',.......'City100')
Expected result
1. City1 Exist
2. City2 Exist
3. City3 Not Exist
4. City4 Exist
5. City5 Not Exist
Thanks.
Try it like this: Just paste my code into an empty query window and execute. Adapt to your needs (most important is to replace the "#ExistingCities" with your actual table's name):
First I declare a "table" with some already existing cities (3 and 5 are missing). The input string misses City4.
DECLARE #ExistingCities TABLE(CityName VARCHAR(100));
INSERT INTO #ExistingCities VALUES('City1'),('City2'),('City4'),('City6');
DECLARE #Input VARCHAR(MAX)='City1,City2,City3,City5,City6';
WITH SplittedInput AS
(
SELECT CAST('<x>' + REPLACE(#input,',','</x><x>') + '</x>' AS XML) AS CitiesAsXml
)
SELECT oneCity.value('.','varchar(max)') AS InputName
,CASE WHEN exC.CityName IS NOT NULL THEN 'Exist' ELSE 'Not Exist' END AS ResultCode
FROM SplittedInput
CROSS APPLY CitiesAsXml.nodes('/x') AS InputCity(oneCity)
LEFT JOIN #ExistingCities AS exC ON exC.CityName=oneCity.value('.','varchar(max)')
Please check following SQL script,
For demo I created a sql CityList table with sample data
create table cityList (id int identity(1,1), city nvarchar(50),)
insert into cityList(city) values ('City1'),('City3')
declare #input nvarchar(max) = 'City1,City2,City3,City4,City100'
select
s.val,
case when c.city is not null then 'Exist' else 'Not Exist' end
from dbo.split(#input,',') s
left join cityList c on c.city = s.val
Please note that you need the SQL string Split function codes for dbo.split() function
I hope it helps

I start to work on old project and there is sql server database column which stores articles numbers for example as follows:
11.1006.45
11.1006.46
11.1006.47
01.10012.11
01.10012.12
2.234.1
2.234.2
2.234.3
657.104324.32
Every number contains 3 parts. First part describe what producent it is and that's something i have to change when user choose diffrent number for specific producent. For example producent number 2 will be now 13 so according to our examples:
2.234.1
2.234.2
2.234.3
has to be done this way right now:
13.234.1
13.234.2
13.234.3
I am looking for sql query which would find all records where producent number is e.g 2.xxxxx and then replace to 13.xxxxx. I would like this query to be secure to avoid any issues with numbers replacments.Hope you understand what i ment.
You could use this for update. '2. and 13.' could be any other string
DECLARE #SampleTable AS TABLE
(
Version varchar(100)
)
INSERT INTO #SampleTable
VALUES
('11.1006.45'),
('11.1006.46'),
('11.1006.47'),
('01.10012.11'),
('01.10012.12'),
('2.234.1'),
('2.234.2'),
('2.234.3'),
('657.104324.32')
UPDATE #SampleTable
SET
Version = '13.' + substring(Version, charindex('.', Version) + 1, len(Version) - charindex('.', Version))
WHERE Version LIKE '2.%'
SELECT * FROM #SampleTable st
Demo link: Rextester
update t
set t.col= replace(yourcol,substring(yourcol,1,charindex('.',yourcol,1),2)
from table t
this finds first character before first dot
substring(yourcol,1,charindex('.',yourcol,1)
then you use replace ,to replace it with whatever you need
You can use this query for multiple updation,
DECLARE #Temp AS TABLE
(
ArtNo VARCHAR(100)
)
INSERT INTO #Temp
VALUES
('11.1006.45'),
('11.1006.46'),
('11.1006.47'),
('01.10012.11'),
('01.10012.12'),
('2.234.1'),
('2.234.2'),
('2.234.3'),
('657.104324.32')
UPDATE #Temp
SET ArtNo = CASE WHEN SUBSTRING(ArtNo,1,CHARINDEX('.',ArtNo)-1) = '2' THEN STUFF(ArtNo,1,CHARINDEX('.',ArtNo)-1,'13')
WHEN SUBSTRING(ArtNo,1,CHARINDEX('.',ArtNo)-1) = '11' THEN STUFF(ArtNo,1,CHARINDEX('.',ArtNo)-1,'15')
ELSE ArtNo
END
SELECT * FROM #Temp
I have a comma-separated list column available which has values like
Product1, Product2, Product3
I need to search whether the given product name exists in this column.
I used this SQL and it is working fine.
Select *
from ProductsList
where productname like '%Product1%'
This query is working very slowly. Is there a more efficient way I can search for a product name in the comma-separated list to improve the performance of the query?
Please note I have to search comma separated list before performing any other select statements.
user defined functions for comma separation of the string
Create FUNCTION [dbo].[BreakStringIntoRows] (#CommadelimitedString varchar(max))
RETURNS #Result TABLE (Column1 VARCHAR(max))
AS
BEGIN
DECLARE #IntLocation INT
WHILE (CHARINDEX(',', #CommadelimitedString, 0) > 0)
BEGIN
SET #IntLocation = CHARINDEX(',', #CommadelimitedString, 0)
INSERT INTO #Result (Column1)
--LTRIM and RTRIM to ensure blank spaces are removed
SELECT RTRIM(LTRIM(SUBSTRING(#CommadelimitedString, 0, #IntLocation)))
SET #CommadelimitedString = STUFF(#CommadelimitedString, 1, #IntLocation, '')
END
INSERT INTO #Result (Column1)
SELECT RTRIM(LTRIM(#CommadelimitedString))--LTRIM and RTRIM to ensure blank spaces are removed
RETURN
END
Declare #productname Nvarchar(max)
set #productname='Product1,Product2,Product3'
select * from product where [productname] in(select * from [dbo].[![enter image description here][1]][1][BreakStringIntoRows](#productname))
Felix is right and the 'right answer' is to normalize your table. Although, maybe you have 500k lines of code that expect this column to exist as it is. So your next best (non-destructive) answer is:
Create a table to hold normalize data:
CREATE TABLE ProductsList2 (ProductId INT, ProductName VARCHAR)
Create a TRIGGER that on UPDATE/INSERT/DELETE maintains ProductList2 by splitting the string 'Product1,Product2,Product3' into three records.
Index your new table.
Query against your new table:
SELECT *
FROM ProductsList
WHERE ProductId IN (SELECT x.ProductId
FROM ProductsList2 x
WHERE x.ProductName = 'Product1')
Hi I have the following xml input in a SP.
DECLARE #XmlVariable XML = '<portal><patientid>67518</patientid>
<forms>
<form id="31" type="C"/>
<form id="44" type="D"/>
</forms>
</portal>'
I have the following inmemory table:
DECLARE #TColumns table (
FormId int,
FormType varchar(1),
PatientId int
)
Now, my intention is to:
1.Iterate the xml and insert the values into the #TColumns table.
2.Read the #TColumns table row by row and based on the 3 column values update some existing table;something like
update myexistingtable set status=4 where Formid=31 && Formtype='C' and PatientId=67518.
For item number 1 above, this is what I have done till now, but there is some syntax error:
INSERT INTO #TColumns(FormId,FormType,PatientId)
SELECT
XTbl.Cats.value('.', 'int'),
XTbl.Cats.value('.', 'varchar(1)'),
XTbl.Cats.value('.', 'int')
FROM
#XmlVariable.nodes('/portal/forms/form/#id') AS XTbl(Cats),
#XmlVariable.nodes('/portal/forms/form/#type') AS XTbl(Cats),
#XmlVariable.nodes('/portal/forms/form/#patientid') AS XTbl(Cats)
The error I am getting is:The correlation name 'XTbl' is specified multiple times in a FROM clause.
Need help on this and also on the item number 2 above.
Thanks in advance.
Maybe you want something like this
SELECT
Tbl1.Form.value('#id', 'int'),
Tbl1.Form.value('#type', 'varchar(1)'),
Tbl2.Portal.value('patientid', 'int')
FROM
#XmlVariable.nodes('//form') Tbl1(Form),
#XmlVariable.nodes('//portal') Tbl2(Portal)
This is what helped.Yes its is based on Hogan's last suggestion.Thank you!
INSERT INTO #TColumns(FormId,FormType,PatientId)
SELECT
Tbl1.Form.value('#id', 'int'),
Tbl1.Form.value('#type', 'varchar(1)'),
Tbl2.Portal.value('.', 'int')
FROM
#XmlVariable.nodes('//form') Tbl1(Form),
#XmlVariable.nodes('//patientid') Tbl2(Portal)
I realize this question has been asked before, but I can't get it to work for some reason.
I'm using the split function from this SQL Team thread (second post) and the following queries.
--This query converts the interests field from text to varchar
select
cp.id
,cast(cp.interests as varchar(100)) as interests
into #client_profile_temp
from
client_profile cp
--This query is supposed to split the csv ("Golf","food") into multiple rows
select
cpt.id
,split.data
from
#client_profile_temp cpt
cross apply dbo.split(
cpt.interests, ',') as split <--Error is on this line
However I'm getting an
Incorrect syntax near '.'
error where I've marked above.
In the end, I want
ID INTERESTS
000CT00002UA "Golf","food"
to be
ID INTERESTS
000CT00002UA "Golf"
000CT00002UA "food"
I'm using SQL Server 2008 and basing my answer on this StackOverflow question. I'm fairly new to SQL so any other words of wisdom would be appreciated as well.
TABLE
x-----------------x--------------------x
| ID | INTERESTS |
x-----------------x--------------------x
| 000CT00002UA | Golf,food |
| 000CT12303CB | Cricket,Bat |
x------x----------x--------------------x
METHOD 1 : Using XML format
SELECT ID,Split.a.value('.', 'VARCHAR(100)') 'INTERESTS'
FROM
(
-- To change ',' to any other delimeter, just change ',' before '</M><M>' to your desired one
SELECT ID, CAST ('<M>' + REPLACE(INTERESTS, ',', '</M><M>') + '</M>' AS XML) AS Data
FROM TEMP
) AS A
CROSS APPLY Data.nodes ('/M') AS Split(a)
SQL FIDDLE
METHOD 2 : Using function dbo.Split
SELECT a.ID, b.items
FROM #TEMP a
CROSS APPLY dbo.Split(a.INTERESTS, ',') b
SQL FIDDLE
And dbo.Split function is here.
CREATE FUNCTION [dbo].[Split](#String varchar(8000), #Delimiter char(1))
returns #temptable TABLE (items varchar(8000))
as
begin
declare #idx int
declare #slice varchar(8000)
select #idx = 1
if len(#String)<1 or #String is null return
while #idx!= 0
begin
set #idx = charindex(#Delimiter,#String)
if #idx!=0
set #slice = left(#String,#idx - 1)
else
set #slice = #String
if(len(#slice)>0)
insert into #temptable(Items) values(#slice)
set #String = right(#String,len(#String) - #idx)
if len(#String) = 0 break
end
return
end
FINAL RESULT
from
#client_profile_temp cpt
cross apply dbo.split(
#client_profile_temp.interests, ',') as split <--Error is on this line
I think the explicit naming of #client_profile_temp after you gave it an alias is a problem, try making that last line:
cpt.interests, ',') as split <--Error is on this line
EDIT You say
I made this change and it didn't change anything
Try pasting the code below (into a new SSMS window)
create table #client_profile_temp
(id int,
interests varchar(500))
insert into #client_profile_temp
values
(5, 'Vodka,Potassium,Trigo'),
(6, 'Mazda,Boeing,Alcoa')
select
cpt.id
,split.data
from
#client_profile_temp cpt
cross apply dbo.split(cpt.interests, ',') as split
See if it works as you expect; I'm using sql server 2008 and that works for me to get the kind of results I think you want.
Any chance when you say "I made the change", you just changed a stored procedure but haven't run it, or changed a script that creates a stored procedure, and haven't run that, something along those lines? As I say, it seems to work for me.
As this is old, it seems the following works in SQL Azure (as of 3/2022)
The big changes being split.value instead of .data or .items as shown above; no as after the function, and lastly string_split is the method.
select Id, split.value
from #reportTmp03 rpt
cross apply string_split(SelectedProductIds, ',') split
Try this:
--This query is supposed to split the csv ("Golf","food") into multiple rows
select
cpt.id
,split.data
from
#client_profile_temp cpt
cross apply dbo.split(cpt.interests, ',') as split <--Error is on this line
You must use table alias instead of table name as soon as you define it.
Facing problem for generating SQL Server Query
In the Following query dynamic conditions are added to check whether value is null or not
Select *
From tblEmployees
where EmployeeName = Case
When #EmployeeName Is Not Null
Then #EmployeeName
Else EmployeeName
End
But I need to add IN () Conditions and the parameter with in the IN () could be null or blank also ,if the parameter /string which is passed to the IN condition is blank then i donot want to add that condition in the query.
So how can i Achieve this.A helping hand will be very useful for me.
Thanks and Regards,
D.Mahesh
Depending on value of your parameter (blank of not), you can create SQL string accordingly.
DECLARE #sqlCommand VARCHAR(1000)
IF(ISNULL(#YourParameter,'')='')
#sqlCommand = 'your query goes here'
ELSE
#sqlCommand = 'your query goes here'
and then, run it using dynamic query execution
EXEC (#sqlCommand)
If not dynamic query then,
SELECT ....
FROM ....
WHERE CASE WHEN ISNULL(#YourParameter,'')='' THEN '' ELSE EmployeeName END IN (ISNULL(#YourParameter,''))
See if this works...
I think the Dynamic query is the best solution, however you could put the "IS NULL" and "IS BLANK" condition in OR with your IN clause.
Something like that
Select *
From tblEmployees
where #EmployeeName is null or EmployeeName in (#EmployeeName)
When #EmployeeName is null, your IN clause will be ignored
If i get this right you have #EmployeeName = 'Name1,Name2,Name3' and you want to get the employees that is named Name1 or Name2 or Name3, also the variable #EmployeeName can be null or contain an empty string.
Instead of using IN you can split the string #EmployeeName on , and store it in a table variable or temporary table. Then you can use that table in a join against tblEmployees to get the rows you need.
There are a lot of posts in S.O. about how to split a string. Here is one recent variant.
Group by sql query on comma joined column
This will work for SQL Server 2005 or later.
declare #EmployeeName varchar(100) = 'Name2,Name3,Name5'
-- Null or empty will have a comma
set #EmployeeName = coalesce(#EmployeeName, '') + ','
-- cteNames splits the string to rows
;with cteNames
as
(
select
left(#EmployeeName, charindex(',', #EmployeeName)-1) as Name,
right(#EmployeeName, len(#EmployeeName)-charindex(',', #EmployeeName)) as EmployeeName
union all
select
left(EmployeeName, charindex(',', EmployeeName)-1) as Name,
right(EmployeeName, len(EmployeeName)-charindex(',', EmployeeName)) as EmployeeName
from cteNames
where charindex(',', EmployeeName) > 1
)
select E.*
from tblEmployees as E
inner join cteNames as N
on E.Name = N.Name or
#EmployeeName = ','
-- #EmployeeName = ',' will give you all names when #EmployeeName is null of empty
