View 1 Replies View RelatedI was looking at a Miscrosoft example of a SQL "INSERT INTO".
One example they give isINSERT INTO Northwind.dbo.Shippers (CompanyName, Phone)
VALUES (N'Snowflake Shipping',N'(503)555-7233') What does the "N" stand for (or do) in N'Snowflake Shipping'? Is this really needed? I've looked around some and can't find any discussion about it.

In the following example the line of code
IF RIGHT(@StringArray,1) != @Delimiter
includes " != ". What does it mean?
Thanks, Bill
Full Example:-- Creates a UDF that returns a string array as a table result set
CREATE FUNCTION dbo.udf_ParseArray
( @StringArray varchar(max),
@Delimiter char(1) )
RETURNS @StringArrayTable TABLE (Val varchar(50))
AS
BEGIN
DECLARE @Delimiter_position int
IF RIGHT(@StringArray,1) != @Delimiter
SET @StringArray = @StringArray + @Delimiter
WHILE CHARINDEX(@Delimiter, @StringArray) <> 0
BEGIN
SELECT @Delimiter_position =
CHARINDEX(@Delimiter, @StringArray)
INSERT @StringArrayTable
VALUES (left(@StringArray, @Delimiter_position - 1))
SELECT @StringArray = STUFF(@StringArray, 1,
@Delimiter_position, '')
END
RETURN
END
GO
An example for finding the length of a string is:
SELECT LEN (N'She sells seashells by the sea shore')
This returns 37. Without the N, it still returns the same 37. Why is N used?
Thanks.
Bill
Any one help me out ?
Thank you very much .!
Actually, I don't know what is the meaning and difference of "N" in thefunction.Thanks.

LOP_BEGIN_XACT, LOP_COMMIT_XACT,
LOP_INSERT_ROWS
Labels as the ones are easy recognizable when you explore LDFS by mean DBCC or whatever but on the contrary the following ones are tricky to reach the meaning:
LOP_IDENTITY_TYPE
LOP_DELTA_SYSIND
LOP_SET_BITS
Does anyone have any link related with this? I tried hard to search by Goog or something like that but unsuccessfully at all.

Hi,
Does anyone know the meaning of the datacode different values? I understand that 0 is OK and 1 is not, what is the meaning of the rest? I have an execution with no errors except a datacode=3 in the PackageEnd event. What does it mean?
Thanks,
Liran
The documentation says:
"An integer value that identifies the event associated with the log entry. The value 0 indicates the event provided no identifier."
When I look at the sysdtslog90 table and I filter for 'PackageEnd' events, I see a value of 0, 1 or 3 in the datacode column. Is there any information I can glean from these values, e.g. package success or failure?
When you write a sql query, some times there is curly braces within a query in a asp.net application. What is the meaning of that?
select column1, column2, column3

order by column3
So what is being used in here {LIMITDATE} and can some one explain this to me? I use C#.

Dear friends,
I'm reading Wiley's Data mining with SQL Server 2005... There are MANY things I can't understand about MovieClick example (Chapter 3).
I hope someone is going to help me with this troubles...
WARNING (1): I'm a dummy both with sql server and data mining.
WARNING (2): My English is not good at all.
Just two questions for now:
1) When I create the model to predict the number of bedrooms for homeowners, the book says to check BEDROOMS as Predictable... question: is it also an INPUT for the model, or PREDICTABLE only?
2) I'd like to keep this model (number of bedrooms.......) and make a prediction query.
- Query builder
- select case table -> Homeowners
- Drag the Customer ID column from the Homeowners table and drop it on the grid
- Drag the BEDROOMS column from the mining model and drop it on the grid.
- On the last row: Source=PredictionFunction, Field=PredictProbability
- Drag the BEDROOMS column from the mining model and drop it into Criteria/Argument
- Add (i.e.) 'Two or Three' to the field Criteria/Argument
I execute the query and I obtain many rows in a table with the following colums: CustomerID, BEDROOMS and Expression: WHAT DOES THIS MEAN?
WHICH INFO DO I GET FROM THOSE NUMBERS? WHAT CAN I LEARN FROM THEM?
Thanx a lot in advance, please help me!

View 3 Replies View RelatedWhile I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,
Barkingdog
I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
In my report i have CNAME parameter , which allows null value. I checked Allow null value check box in report parameter properties.
when i preview the report , it displays checked NULL check box beside CNAME parameter . I want to give some meaningful name(i.e.ALLCustomers) to this checkbox instead of NULL.
Is it possible through SSRS designer?
I have table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?
Ok,I just need to know how to get the last record inserted by the highestIDENTITY number. Even if the computer was rebooted and it was twoweeks ago. (Does not have to do with the session).Any help is appreciated.Thanks,Trint
View 2 Replies View RelatedHi,
I am having problem in bulk update of a sql server table haning identity column from a datatable( has no identity column) using sqlbulkcopy. I tried several approaches, but it does not show any error nor is the table getting updated. But the identity value seems to getting increased every time.
thanks.

I'm working with a third-party database (SQL Server 2005) and the problem here is the following:
- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).
- The PK of T is an Integer.
Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.
Considering that I can't change the PK, what is the best approach to solve this problem?
To sum up:
* I need to have processes in parallel inserting on T
* I can't change anything on T
* The PK is NOT an Identity
when i alter non identity column to identity column using this Query alter table testid alter column test int identity(1,1) then i got this error message Msg 156, Level 15, State 1, Line 3 Incorrect syntax near the keyword 'identity'.
