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
from table1
where column1 = 'somethin'
{LIMITDATE}
order by column3
So what is being used in here {LIMITDATE} and can some one explain this to me? I use C#.
The Query as follows:
DECLARE @end DATETIME
SET @end = {3}
I tried to read a lot of stuff regarding curly braces in SQL. Couldnt find a full proof answer. Couple of question which comes to my mind are :
1) What is the use of curly brackets in the above query statement?
2) The variable is of the data type DATATIME. Why is an integer variable stored instead ?
If I return a GUID as an output parameter in an ASP page, it has curly braces around it. When I query the table in QA, there are no braces around it. Why is that.

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!
I'm using a Lookup component to add a DT_GUID column named cat_id to a data flow, which is used in a downstream Derived Column component to add a DT_WSTR column named value. The DC expression simply casts the uniqueidentifier to the desired type: (DT_WSTR, 434)cat_id
But when the values are persisted in the destination table's nvarchar(434) column, they have braces around them, e.g. {F475DB7F-5CB0-4EE1-9BF2-758C77D7A6D7}
What is introducing those braces, and what do I need to do to prevent 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

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?

Hi,
I get this error dialog when I try to open all the rows of any table from Enterprise manager..
Any help would be really appreciated..
Thanks,
-Srini.
SQL Server 2005 9.0.3161 on Win 2k3 R2
I receive the following error:
"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I have traced this to an insert statement that executes as part of a stored procedure.
INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)
VALUES (@journal_id, @acct_id, @acct_recv_id, @amount)
There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.
Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).
