View 1 RepliesI 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.

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

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?

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!
