why XML column doesn't let me put anything in it and greyed out, I can populate other columns ID A or ID B I can add values but with Xml it doesn't let me add anything, even "<element>" ?
Creating a table like this,
USE [DBNAME]
GO

I am having a little trouble with my after insert trigger it does not update/insert into the table and I am not sure why.
I have the tables employee, position, certification, employeecertification, positioncertification.
What I need to do is after a Position is assigned a Certification then all employees that are defined in that position (Employee:PositionId = Ins.PositionId] need to get the certification added (if it does not already exist in their record) , I might need to update them where they do exist (but for the moment do not believe that will be a requirement).
I have been getting a couple different results (neither is correct)
1: EmployeeId can not insert null into EmployeeId
2: On some other test data - nothing is inserted.
I have the following trigger with the sql for creation of tables that follows:
The Trigger
CREATE TRIGGER [dbo].[trig_InsNew_PositionCertification]
ON [dbo].[PositionCertification]
AFTER INSERT
AS
Insert into EmployeeCertification
(CertificationId, EmployeeId)
Select Ins.CertificationId, Emp.EmployeeId
From inserted Ins
Left Join dbo.Employee Emp On Emp.PositionId = Ins.PositionId
Left Join dbo.Certification Trw On Trw.CertificationId = Ins.CertificationId
WHERE NOT EXISTS
(SELECT EmployeeId, CertificationId
FROM
EmployeeCertification
WHERE EmployeeId = Emp.EmployeeId AND CertificationId = Ins.CertificationId);

I have this pretty simple table with 17m records in it:
CREATE TABLE [dbo].[LineNumbers](
[Id] [int] IDENTITY(1,1) NOT NULL,
[LineDescriptionId] [int] NOT NULL,
[ProtocolId] [int] NULL,
[Value] [int] NULL,
CONSTRAINT [PK_LineNumbers] PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
Query to the table with additional join works fine, if there is no ProtocolId in it:
select top 1
ln.LineDescriptionId
from LineNumbers ln
join LineDescriptions ld on ld.Id = ln.LineDescriptionId and ld.ProtocolSetId = 25
-- Elapsed time: 00:00:00.1718750
Execution plan: https://www.brentozar.com/pastetheplan/?id=rJV34gvR7
But when I try to add ProtocolId to the field list, query time grows dramatically:
select top 1
ln.ProtocolId
from LineNumbers ln
join LineDescriptions ld on ld.Id = ln.LineDescriptionId and ld.ProtocolSetId = 25
-- Elapsed time: 00:02:19.6464843
Execution plan: https://www.brentozar.com/pastetheplan/?id=SkG-hyDCQ
Also, this works smooth:
select top 1
(select ProtocolId from LineNumbers where LineNumbers.Id = ln.Id) as ProtocolId
from LineNumbers ln
join LineDescriptions ld on ld.Id = ln.LineDescriptionId and ld.ProtocolSetId = 25
-- Elapsed time: 00:00:00.1718750
Tried this queries and variations on Azure DB and local MSSQL 2017. Results are the same. As long as I keep ProtocolId out of the field list everything is fine.
Is there some mistake in my data scheme (everything was created via migrations of Entity Framework)?
CREATE TABLE [dbo].[LineNumbers](

Eventually, I solved it by adding nonclustered index on field LineNumbers.LineDescriptionId with inclusion of LineNumbers.ProtocolId
CREATE NONCLUSTERED INDEX [IX_LineNumbers_LineDescriptionId_ProtocolId] ON
[dbo].[LineNumbers]([LineDescriptionId] ASC)
INCLUDE ([ProtocolId])
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF,
SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF,
ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON)
Result:
SELECT TOP 1
ln.ProtocolId
FROM LineNumbers ln
JOIN LineDescriptions ld ON ld.Id = ln.LineDescriptionId AND ld.ProtocolSetId = 25
-- Elapsed time: 00:00:00.1403155
Execution plan: https://www.brentozar.com/pastetheplan/?id=Syywn1wRQ
Why does it work that way?
For example, if I'd do similar use case with PostgreSQL then there is no need in any additional indexes at all (beside obvious FK indexes on ProtocolId and LineDescriptionId fields).
I have a MS SQL table with approx 30M rows that I need to update a field based on the previous records. Here is an update that works but it is taking an incredible amount of time:
UPDATE AccountTransaction
SET EndingBalance = (SELECT COALESCE(SUM(b.amount), 0)
FROM AccountTransaction AS b
WHERE b.AccountId = AccountTransaction.AccountId
and b.Date <= AccountTransaction.Date
and (b.Date != AccountTransaction.Date
or b.CreatedDate < AccountTransaction.CreatedDate))
+ Amount
Here is the full DDL:
CREATE TABLE [dbo].[AccountTransaction](
[AccountTransactionId] [uniqueidentifier] NOT NULL,
[AccountId] [uniqueidentifier] NOT NULL,
[Amount] [decimal](16, 2) NOT NULL,
[EndingBalance] [decimal](16, 2) NOT NULL,
[Date] [date] NOT NULL,
[CreatedDate] [datetime2](3) NOT NULL,
CONSTRAINT [PkAccountTransaction] PRIMARY KEY CLUSTERED
(
[AccountTransactionId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
CREATE NONCLUSTERED INDEX [IxAccountTransaction_AccountId_Date_CreatedDate] ON [dbo].[AccountTransaction]
(
[AccountId] ASC,
[Date] ASC,
[CreatedDate] ASC
)
INCLUDE ([AccountTransactionId],
[Amount],
[EndingBalance]) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
GO
CREATE NONCLUSTERED INDEX [IxAccountTransaction_AccountId] ON [dbo].[AccountTransaction]
(
[AccountId] ASC
)
INCLUDE ([AccountTransactionId],
[Amount],
[EndingBalance],
[Date],
[CreatedDate]) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
GO
The following should yield much better performance and will be able to take advantage of the IxAccountTransaction_AccountId_Date_CreatedDate index...
WITH
cte_Runningtotal AS (
SELECT
at1.EndingBalance,
NewEB = SUM(at1.Amount) OVER (PARTITION BY at1.AccountId ORDER BY at1.[Date] ROWS UNBOUNDED PRECEDING)
FROM
dbo.AccountTransaction at1
)
UPDATE rt SET
rt.EndingBalance = rt.NewEB
FROM
cte_Runningtotal rt;

my problem that seek by time interval between 2 date time is really slow , also it became more slow if i select with message sensor data , also when i use sp_BlitzIndex check from brentozar.com it say that i have
"Indexaphobia: High value missing index"
[aymax].[MessageSensors] (EQUALITY: [DataSourceId], [Value] INCLUDES: [MessageId] )
[aymax].[MessageSensors] EQUALITY: [Value] INCLUDES: [MessageId], [DataSourceId]
I belive that create this 2 index is will increase storage alot , also will take too much time to be created , i need your advice for both table regarding index

any help please , i need to make a fast retrieve from message , and message sensor
update
while doing some investigate i found that select float value will slow up the result too much , from 1 second to 3 minutes
SELECT m.messageid,
m.objectid,
m.gpstime,
m.x,
m.y,
-- slow is here if i replace md.value with md.messageId will return fast , md.value is float
md.Value ,
0
FROM aymax.[message] m WITH (nolock)
left JOIN aymax.MessageSensors md WITH (nolock)
ON m.messageid = md.messageid
AND md.datasourceid = 425732
WHERE m.objectid = 14099
AND m.gpstime BETWEEN '2017-04-01 19:46:18.607' AND '2017-04-10 19:05:18.607'
Possible solutions:
Filtered index (filter by date and do not index old data)
https://learn.microsoft.com/en-us/sql/relational-databases/indexes/create-filtered-indexes.
Clustered index on GpsTime, MessageId (Espessially if you have no plans about another indexes). Requires rebuild your table.
Partitions (see #Siyaul's comments)

I think the problem is that both tables need to be matched completely and then sorted on name before the where clause can throw out the trash.
I'm not sure this will help, but it's worth a shot - try adding the name to the index:
CREATE NONCLUSTERED INDEX [IX_CCWiseDocumentNames2_ID] ON [dbo].[CCWiseDocumentNames2]
(
[ID] ASC,
[Name] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
You don't need to have PK or Identity, so you still can create clustered index on ID column. It alows repeating values, and the only thing you should be worrying about is INSERT performance if you're the IDs are not appended, but added in the middle.
Why are you using row_number() in outer query? I think the same result can be achieved in single select (maybe you'll have to change the ranking function and use partitioning).
Btw if your inner query does not return unique NAME and you're using row_number without partitioning, then peta_rn may return misleading values (same name with many different peta_rn). I'm just guessing because I don't know what exactly are you trying to achieve.
Go with the clustered index and you'll bring it under 1s no problem.
