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);

I am using SQL Server 2014 and want to get all the tables name in a particular database STUDENT through a SQL query.
How is it possible?
Thanks
You want to query sys.objects and look for everything with the type description 'USER_TABLE'. You could use a query like this;
SELECT
*
FROM STUDENT.sys.objects
WHERE type_desc = 'USER_TABLE'
The FROM clause has the usual format: DatabaseName.SchemaName.TableName.
Or as marc_s mentions, you can use sys.tables instead;
SELECT
*
FROM STUDENT.sys.tables

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 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 use LIMIT into SQL server 2008 but its not working, what can I do, I am new to SQL I have used mySQL before.
Here is the SQL query I am trying:
SELECT * FROM konto WHERE id_e_klientit = 9 ORDER BY koha_relizimit DESC LIMIT 1
Try SELECT TOP 1 * ...
Also see http://www.w3schools.com/sql/sql_top.asp for more details.
In MSSQL it's apparently something like SELECT TOP x * FROM ...
SELECT TOP 1 * FROM konto WHERE id_e_klientit = 9 ORDER BY koha_relizimit DESC
