I would like to know how data is inserted and selected from table internally. Like how buffers are created and how they are executed.
Eg. Table1
col1 col2 col3
1 a 1
2 b 2
I want to know how this data is inserted into tables. How many buffers are created ? Does it depends on the columns? How buffers are executed?

I need to find the data, When was data last inserted/updated/deleted in a specific table?. is it possible?
Table name: Employee
Within a trigger, I'm trying to create a unique table name (using the NEWID()) which I can store the data that is found in the inserted and deleted tables.
Declare @NewID varchar(50) = Replace(convert(Varchar(50),NEWID()),'-','')

But I don't want to use TempDB as these tables can become big and I also feel that it is redundant. Is there a way to avoid the creation of #inserted?
I am looking for a Sql query to verify the inserted values from one table(in CSV file) with another table(in sql database)
For example: I have below Values column that is present in once CSV file, after my data migration the values get stored in Results table under Message column.
I need to very whether values(1X,1Y) are inserted in Message record "successfully inserted value 1X"
Values (CSV)
1X
1Y
Results Table(SQL)
CreatedDate Message
2015-08-04 08:45:29.203 successfully inserted value 1X
2015-08-04 08:44:29.103 TEst pass

2015-08-04 08:30:29.203 Test Pass
2015-08-04 08:28:29.203 successfully inserted value 1Y
If all values are inserted:
Output:
All values from values table are inserted successfully
Total count of values inserted: 2
If only few values are inserted, example only 1X from Values table is inserted in Message

I want to insert a row for a Global user in Table 'A' whenever ADO.Net code inserts a Local user row into same table. I recommended using a trigger to implement this functionality, but the DBA was against it, saying that stored proecedures should be used, since triggers are unreliable and slow down the system by placing unecessary locks on the table. Is this true OR the DBA is saying something wrong? My thinking is that Microsoft will never include triggers if they are unreliable and the DBA is just wanting to offload the extra DBA task of triggers to the programmer so that a stored procedure is getting called, so he has less headache on his hands.Thanks

Can I dump the 'inserted' table to a temp table WITHOUT specifying the column names?

View 2 Replies View RelatedTrying to get my head around this table:
I thought it contained all data used in an insert; meaning if i enter a row in a table the inserted table should then contain all data entered?
Ive created multiple tables linked via primary key Learner_ID this key is unique to any/all students and can never be duplicated hence i thought i would use it to link the tables.
I have tables Fab / Main / Elec / Learner_info / WS_WR.
For Fab / Main / Elec the only data i need form Learner_info is the Learner_ID field, i simply used:
INSERT INTO FAB(Leaner_ID)
SELECT Learner_ID
FROM Inserted
as a trigger to insert the ID into these tables. Everything works perfectly fine. So i assumed that i would be able to use something very similar to insert say:
Learner_ID, FNAME, LNAME, ONAME and C_NUM from the learner_info table into the WR_WS table. Apparently i was wrong I can insert the learner_ID perfectly but if i then try to add another insert trigger eg: insert fname i get an sql error:
Cannot insert the value NULL into the column 'LEARNER_ID', table 'swdt_im.WS_WR'; column does not allow nulls. INSERT fails.
Now from reading the error it suggests to me that because the second trigger is running my learner_id value has become a NULL. Obviously a primary key wont accept this value so the statement fails.
What im struggling to understand, im sure i will solve the problem eventually but i would apreciate help, and this is most important to me rather than a solution is this:
If i enter data into a row on a table does that data go into the inserted table in the same row? or does the data go into inserted as a single entry row, meaning when i tab along from learner_ID into FNAME does Learner_ID become row 1 (in inserted) and FNAME the current row? or do they go into the appropriate columns?
I was under the assumption that i could enter:
LEARNER_ID / FNAME / LNAME / ONAME / C_NUM
into one table and have a trigger insert those values into multiple other tables. Dont suppose someone can help me out im alright querying a SQL db but ive never had to develop anything other than a single table one myself before
Thanks in advance
We are trying a cluster setup on MS SQL 2005 with one m/c as Publisher (Primary) and another as Subscriber (Secondary).
When Publisher and Subscriber both are running, everything goes fine but when Publisher server goes down, subscriber server troubles.
We are using MSADO15.DLL for database connectivity.
We have a table where ID column is set to primary key with Auto Increment true.
We use AddNew() function of this library to insert a new record.
We fill a structure with all necessary values to pass it to AddNew() with ID field set to 0.
When we use AddNew() on the above table to insert a record, the ID auto inserted in table is correct but returned structure contains wrong ID value.
We tried to trace this problem using SQL Server Profiler Tool of SQL Server.
AddNew() function performs following operations in back end
1. Inserts the record to the table using INSERT
2. Calculates the auto increment field ID using SELECT @@IDENTITY
3. Fills this ID in the structure passed to AddNew() and returns it.
But ID returned by SELECT @@IDENTITY query is wrong.
There are other ways also to retrieve the last ID inserted in table by
IDENT_CURRENT(‘table_name’) which return right ID.
Can we change the call of SELECT @@IDENTITY to IDENT_CURRENT in AddNew() functions behavior of MSADO DLL?
Or there is another way of retrieving right ID

dear all,
I have a WCF service which is host in a console application for the time beeing.
This service provide methods for retriving history data when request.
So far so good.
My WCF service need also to know when a particular table (ALARMS tabel ) gets updated with DELETE, INSERT, OR UPDATE. This because my client application (WinForm) need to refresh a datagrid binding to that ALARMS table.
In other words my WCF servcie would send a callback event to my client when it as been notice for a change..
But my problem is how my WCF service can be notify from an update in my SQL table ?
I have tried SQLDependency class, but I give up was not working properly...and hard to know the xact context you are runing on.
Was thinking also of having a timer whcih pool every 1s by calling my tabel store procedure and verifiy is somerow ha changed....
What to do, how to do, what is the best way and thred safe method

Hello,
I have 2 tables, and use objectdatasource and stored procedures, with sql server.
Let say in the first table I have IDCustomer as a datakey, and other records, and in the second I have the same IDCustomer and CustomerName. I have an INSERT stored procedure that will create a new record in the first table (so generate a new IDCustomer value), and I would like to insert immediately this new value in the second table.
How can I know the value of this new IDCustomer ? What is the best way to handle that ? Once the insert in the first table is done should read it the table and extract (with an executescalar) the value and then insert it in the second table ? This solution should work but I am not sure this is the best one.
Thanks for your help.

Hi,
Now thanks to you good folks on here, I have recently found out that when inserting data into table, there is a system table which can be queried with triggers - specifically called "Inserted".
What I am wondering is what are the limitations of what I can do with the data in this table?
I know I can query it from within the trigger, but can I update data specifically in this table before it is inserted?
(ie IF field1 FROM inserted = 'blah' UPDATE inserted SET field2 = 'something')
If so is there anything that I need to look out for? Concerns? Etc?
Thanks in advance for your help
Cheers
hi
for after trigger the records stored in followig table

but i want to know where this tables physically stored ...i mean in which database master or some other database?
and 2nd thing tigger fired for each row or for only insert,delete,update statement?
thanx
Hi,
I am building my after update trigger. The code snippet looks like this:
DECLARE Curs_PrimKey CURSOR FORSELECT * FROM Temp_PrimKeyOPEN Curs_PrimKeyFETCH NEXT FROM Curs_PrimKey INTO @P_KeyWHILE @@FETCH_STATUS = 0BEGIN EXEC('INSERT INTO Temp_Value SELECT '+ @P_Key + ' FROM inserted') SELECT @P_Key_Value = (SELECT PValue FROM Temp_Value) EXEC('DELETE FROM Temp_Value') SELECT @P_Key_Insert = @P_Key_Insert + @P_Key + ' = ' + @P_Key_Value + ', ' FETCH NEXT FROM Curs_PrimKey INTO @P_KeyENDCLOSE Curs_PrimKeyDEALLOCATE Curs_PrimKey
You must know that in the trigger after update there is a special table called inserted. From the code above you can see that I am trying to loop all primary key which is included in Temp_PrimKey. Based on the key I want to select the value from table inserted. If I update a row in the table it gives error:
"No row was updated.
The data in row 13 was not committed.Error Source: .Net SQLClient Data Provider.Error Message: Invalid object name 'inserted'."
I am guessing that if we EXEC the query it is not execute inside the trigger environment, hence it doesn't find the table 'inserted'. Can anybody tell me how to work around this? Thanks.
is there any way of getting the identity without using the "@@idemtity" in sql??? I'm trying to use the inserted event of ObjectDataSource, with Outputparameters, can anybody help me???
View 1 Replies View RelatedQuick history, I have substantial experience using MS Access, VBA, and Regular Expressions to clean up messy text files for use in MS Access.
I want to upgrade an MS Access back end to SQL Server (2008 to be specific). I need to upload several delimited files on a daily basis. The files are full of formatting that I strip out using VBA and Regular Expressions. I've poked around on the site and found some UDFs that implement the VbScript Regular Expressions object as a stored procedure in Transact SQL.
My questions is, am I better off processing the files externally using a procedural language like VB or can SQL Server handle the processing as gracefully as MS Access/VBA/RegEx does?
Thanks for letting me tap into your experience.
I could simply puzzle it out myself by implementing it in SQL Server but I'd rather not waste the time as a newb to transact SQL and then find out that I'd be better off doing it externally.
