Upserting in MS-access
(6 answers)
Closed 7 years ago.
I want to check whether a row exists or not before inserting a new one in Access 2007.
I have the following working query in SQL Server but I'm having trouble converting it to Access.
update category set name='hell' where categoryid=287
if ##rowcount=0
begin
insert into category(categoryid,name,path,parentcategoryid,creationdate) values (287,'a','a',12,'')
end
Try this
update category set name='hell' where categoryid=287;
if not exists(select * from Category where categoryid=287)
insert into category(categoryid,name,path,parentcategoryid,creationdate)
values (287,'a','a',12,'');

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
(18 answers)
Closed 2 years ago.
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)

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

I have try to use statement below in my SQL. Is it possible by any means to dynamically select table form database. (For example select table name from Comobox and then display data from selected table)
SET #var1 = 'test';
SELECT * From #var1
Dynamic SQL requires that you create a string consisting of the sql statement, and then you execute the string. Dynamic t-sql quotes in string
