I want to extract a certain part of a row. if there is something like this ..." abcd - productA", " zas1234 - productC", how do I extract everything before the dash(-)?
I tried a left(column name,'-') it didnt work. I am on SQL Server 2012.
The column from which I am trying to extract is a varchar column.
It would be great if someone could help me.
Try this,
select SUBSTRING(column_name, 1, CHARINDEX('-', column_name)-1) from table_name;
DECLARE #varStr VARCHAR(MAX)
SET #varStr='abcd - productA'
SELECT CHARINDEX('-',#varStr)
SELECT LEFT(#varStr,CHARINDEX('-',#varStr)-1)

I am trying to calculate the date difference and keep getting a column name error. I am new to SQL and learning from books and YouTube. Any assistance would be appreciated. I commented out the code not working
declare #rpDT datetime
set #rpDT = getdate()
SELECT [OrgKey]
,[visID]
,[visPatID]
,[visInternal]
,[visName]
,[visAssignedNS]
,[visAssignedRoom]
,[visAssignedBed]
,[visAdmitDT]
,isnull([visDischargeDT],#rpDT)as disDT
,datediff(day,[visAdmitDT],disDT) as Pt_days
FROM [MH_Pharmacy_Hub].[MC].[dbo_Visits]
SQL Server and most of the RDBMS do not allow to reference column at the same level. The closest equivalent to achieve similar effect is CROSS APPLY:
declare #rpDT datetime = getdate();
SELECT [OrgKey]
,[visID]
,[visPatID]
,[visInternal]
,[visName]
,[visAssignedNS]
,[visAssignedRoom]
,[visAssignedBed]
,[visAdmitDT]
,s.disDT
,datediff(day,[visAdmitDT],s.disDT) as Pt_days
FROM [MH_Pharmacy_Hub].[MC].[dbo_Visits]
CROSS APPLY (SELECT COALESCE([visDischargeDT],#rpDT)) AS s(disDT);

A SQL Query to select a string between two known strings

I have a string like
https:\/\/www.abc.ca\/v3\/homes\/190135717\/responses\/bulk?page=5&per_page=100
I want everything after the equal sign = and before &, i.e the number 5 in SQL Server
Try this below logic using SUBSTRING and CHARINDEX:
Demo Here
DECLARE #T VARCHAR(200) = 'https:\/\/www.abc.ca\/v3\/homes\/190135717\/responses\/bulk?page=5&per_page=100'
SELECT SUBSTRING(#T,CHARINDEX('=',#T,0)+1,CHARINDEX('&',#T,0)-CHARINDEX('=',#T,0)-1)

In a nvarchar(512) field if i store unicode chars like this:
UPDATE MYTABLE SET UNICODEFIELD = 'TﾚEﾎSￔTﾙ'
when i query it i get
T?E?S?T?
It looks like the "unusual" chars are not considered as unicode, i would expect the "?" behavior in case of varchar, while with nvarchar it should work fine, i am expecting
TﾚEﾎSￔTﾙ
as output, instead of
T?E?S?T?
Does anyone have an idea about this?
Because you're using a varchar, not an nvarchar. 'TﾚEﾎSￔTﾙ' = 'T?E?S?T?' as characters like ﾚ can't be stored in a varchar.
Use a literal nvarchar:
UPDATE MYTABLE SET UNICODEFIELD = N'TﾚEﾎSￔTﾙ';

How can I pass variable in Group BY expression.Here is my code.
and from #Varientsku I want to pass column name
Create Proc spIsUnique
#varientsku nvarchar(max) output
As
Begin
select #varientsku,
IIf (count(*)>1,'Dublicate','True') as Total from product group by
#varientsku
End.
and I get this error.
Each GROUP BY expression must contain at least one column that is not an outer reference.
Help me to solve this
You need dynamic sql
EXEC ('select '+#varientsku+',
IIf (count(*)>1,''Duplicate'',''True'') as Total
from product
group by '+#varientsku)
Note : Make sure #varientsku is sanitized, this code is vulnerable to sql injection

Removing leading zeroes from a field in a SQL statement

Is this possible in T-Sql and how?
Use PatIndex
declare #s varchar(20)='0023aff'
select substring(#s,PATINDEX('%[^0]%',#s),LEN(#s))
