Why don't i ever get return value of 1 when the following binary column (profSignature) is null?
RETURN SELECT ISNULL(profSignature, profSignature) FROM mpProfiles WHERE ApplicantID = CAST(@CID AS INT) AND ProfileID = CAST(@PID AS INT)
Im having some unexpected results from combining ISNULL with logical and '&&' and conditions '?:' in derived columns.
This works and returns A or B.
(ISNULL(Col1) && Col2 == "X") ? "A" : "B"
This fails returning Null when Col1 is null
(Col2 == "X" && ISNULL(Col1)) ? "A" : "B"
This fails returning null when Col1 is null
(ISNULL(Col1) && Col2 == "X") ? "A" : (ISNULL(Col1) && Col2 == "Y") ? "B" : "C"
I've applied service pack one and still have the issue. I've also tried using ISNULL in a condion like (ISNULL(Col1) ? TRUE : FALSE)
Anyone else seen this behavior?

I have a table with 10 rows with a varbinary column
I wish to concatenate all the binary column into a single binary column and then write that to another table within the database. This application splits a binary file (Word or PDF document) into multiple segments (this is Column2 as below)
example as follows
TableA
Column1 Column2 Column3
aaa 001 <some binary value>
aaa 002 <some binary value>
aaa 003 <some binary value>
aaa 004 <some binary value>
aaa 005 <some binary value>
desired results in TableB
Column1 Column2
aaa <concatenated value of above binary columns>
Hi ,Have a Visual C++ app that use odbc to access sql server database.Doing a select to get value of binary field and bind a char to thatfield as follows , field in database in binary(16)char lpResourceID[32+1];rc = SQLBindCol(hstmt, 1, SQL_C_CHAR,&lpResourceID,RESOURCE_ID_LEN_PLUS_NULL , &nLen1);and this works fine , however trying to move codebase to UNICODE antested the followingWCHAR lpResourceID[32+1];rc = SQLBindCol(hstmt, 1, SQL_W_CHAR,&lpResourceID,RESOURCE_ID_LEN_PLUS_NULL , &nLen1);but only returns 1/2 the data .Any ideas , thoughts this would work fine , nit sure why loosing dataAll ideas welcome.JOhn

i have a derived column which contains the days of a month from 1 to 31
I have this expression for column 1:
(DT_R4)([1] == 4 ? 0.5 : ISNULL([1]) ? 0.0 : 1.0)
But the ISNULL function will not work. I am sure, there are some NULL Values in Column [1] but i get all the Time the value 1.0 back.
I need the Value 0 instead of NULL to calculate the days in an extra Column.
So that i have in the end a result column which have values for example: 4,5 or 5,5 .why ISNULL is not working?
Hi I have an image column (Spectrum) in a Table (ParticleEDS) which is populated with an array of a bunch of INT32's (4 bytes each)
Using TSQL is there any way that I can read each 4 bytes (convert this to an INT) and return this data for a given record (based on ParticleEDSID).
I know that there are 2048 x 4 bytes that make up the image column.
I would like the output of the query/stored procedure to be:

I have a table called 'Articles' whose columns are articleId (int), authorName (varchar) and article (binary). The primary key is articleId. I tried using DTS wizard available in Enterprise Manager 2000, to import the data from this table into a remote database table, but the data copy failed. I am thinking the binary column is causing the DTS data copy to fail.
If someone could tell me what else I could do to transfer binary data to remote database(like an example of a data transfer query), then that would help me greatly.
The last two columns in one table is [StarText](varchar(20)) and [Star] (binary). It stored data like below:

For example, at column [Star]
row1 insert 3 stars
row2 insert 2 stars
row3 keep null
row4 insert 5 stars
I have a design oriented question for a system I am developing. Because of various business concerns and issues we have been moving towards as desing that brings files into the SQL 2005 system as binary columns in a database. These files will then be processed at a later time using SSIS into relation model tables.
Normally I would just have the process be files are placed on a FTP location (or other drive path) and a location is stored in the database versus the storing of them as binary rows in the database. Then later the SSIS package runs using the path information for the conneciton manager.
Based on the proposed binary design I have two questions.
1. Can anyone speak to the advantages, disadvantages, issues they have had, etc to the binary storage method?
2. Can anyone make a suggestion on how they would handle the pulling of the file out of SQL when the file is ready to process? Do you stream it to a file and rebuild it on the physical disk, to then just import it with a connection manager for the flat file structure.... or can you stream it directly into a conneciton manager that reads it like a flat file and parses the file without ever going to disk? Any information on suggested implementations would be helpful.
Thanks.
Can anyone provide me with some SQL that will identify rows from a table where a varchar column named "Notes" contain Carriage Returns?

Hi folks,I have an issue with a column I created in my query called Instance.SELECT Object_Id, Event_type, Audience, Subject, Provider, Academic_Year, Start_date, End_date, CONVERT(varchar, Academic_Year) + ' (' + CONVERT(varchar, Start_date, 103) + ') : ' + Event_type AS InstanceFROM EventsORDER BY Event_type Above is my query. The problem is because the start date column can be null, it also returns the Instance column as null for that row.I thought it would have just missed out the date and display the rest, but it doesn't.Is there any way I could get the Instance column to display a value, when the start date is null?ThanksEdit: Managed to sort it using ISNULL()

Hi People,
I am having a table which has some 10 cols, only one column had all Nulls. DB-SQL2K5
I am now writing a query like
Update Test1
set Id =
(Select t2.Id from
Test2 t2, Test1 t1
where
t2.Name = t1.Name)
as likely this query is faling as the sub query is retuning more than a row. What is the best method to achive my requirement?
Thanks
I have a Column called SaleID in some tables in a Database.The SaleID column has the int datatype. I need a stored procedure that returns the next value in sequence for the SaleID column.
For Example,
If the last value inserted into the SaleID column was 1022 the stored procedure should return 1023
If the last value inserted into the SaleID column was 1023 the stored procedure should return 1024.
If the last value inserted into the SaleID column was 1024 the stored procedure should return 1025.
Also an exclusive lock should be maintained while the the stored procedure is running.
I am using SQL Server 2005.

Dear all hi,
I would like to create a function that will return to me the width of the column of the table without giving as a parameter the table name. I need it, as I want to exceed my data in this column to the column length. I want to fill the column data with trailing blanks until I reach the column width. The function len returns the length of the data in the column.
I know that If I have the table name I can find the column width through the system tables. I don€™t want this.
Sincerely,
Hellen
Hello!
Is there a function that gets the name of a column and a string as arguments and returns the position of this string in the column given?
Thank you in advance.
I wrote this query to pull some information involving 3 tables dbo.NewFamNbrs$, dbo.CGIItemMaster and dbo.CGIFamilyMaster. In addition I want to perform an update statement to update column dbo.CGIItemMaster.FamilyIDX with the information of dbo.CGIFamilyMaster.IDX. I also know that truncation is indicating that I'm trying to insert data into a field not large enough. So I performed a len() function on the both columns and order by desc and they both came up with 4 as being the max.
Query:
SELECT a.PART, a.Family, b.FamilyIDX, c.FamilyID, c.IDX
FROM dbo.NewFamNbrs$ a LEFT OUTER JOIN dbo.CGIFamilyMaster c ON a.Family = c.FamilyID LEFT OUTER JOIN dbo.CGIItemMaster b ON a.PART = b.PART
Results of query:
PART Family FamilyIDX FamilyID IDX
000127233TF011468 TF01 506
000129880TF011468 TF01 506
003110 MET061468 MET06 1915
UPDATE STATEMENT:
begin tran
update dbo.CGIItemMaster
set FamilyIDX=c.IDX
FROM dbo.NewFamNbrs$ a LEFT OUTER JOIN
CGIFamilyMaster c ON a.Family = c.FamilyID LEFT OUTER JOIN
dbo.CGIItemMaster b ON a.PART = b.PART
When I set a column to have a default definition that uses a UDF, I am receiving the "String or binary data would be truncated" error.
The UDF:
Code BlockALTER FUNCTION GetDefaultClientTier
(
@ClientAssets decimal(15,2)
)
RETURNS char(1)
AS
BEGIN
DECLARE @Result char(1)
-- Get the first result in case of overlaps.
SET @Result = CAST((SELECT TOP 1 ClientTier FROM ClientTiers WHERE @ClientAssets BETWEEN ClientAssetsFloor AND ClientAssetsCeiling) AS char(1))
RETURN @Result
END
ClientTier is defined as char(1) in the table. I simply have (isnull([dbo].[GetDefaultClientTier]([ClientAssets])),(null))) as the definition. I can't use a computed column because I the values need to be editable. When inserting with SSIS, the insert works fine but the column has a value of null for each row.
When putting a character as the default (like 'A') the insert works fine.
The cast is there only because I have tried everything I can think of to get around this.
Is there something simple I am overlooking?

Is there a way to check for System.BDNull when I use the column name instead of column index? The column Photographer (in the excample below) sometimes contains the value null, and then it throws an error.

I have a table filled with GPS readings. I've got a column LATITUDE (FLOAT) with about 20,000 records between 35.6369018 and 35.639890. (Same value to the first 5 digits of precision---what can i say, it's a good gps.)
Here's what happens when I ask SQL Server ("9.00.1399.06 (IntelX86)") to compute the standard deviation of the latitude:
// Transact-SQL StdDev function:
SELECT STDEV(LATITUDE) FROM GPSHISTORY
WHERE STATTIME BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
0
// Zero. ZERO??!?!!
//Let's re-implement Std Dev from the definition using other aggregate functions:
DECLARE @AVERAGE FLOAT;
SELECT @AVERAGE = AVG(LATITUDE) FROM GPSHISTORY
WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
SELECT SQRT(SUM(SQUARE((LATITUDE - @AVERAGE)))/COUNT(LATITUDE)) FROM GPSHISTORY
WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
6.03401924005392E-06
// That's better. Maybe STDEV is using fixed point arithmetic?!?
SELECT STDEV(10 * LATITUDE)/10 FROM GPSHISTORY
WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;

SELECT SQRT(SUM(SQUARE(100*(LATITUDE - @AVERAGE)))/COUNT(LATITUDE))/100 FROM GPSHISTORY
WHERE GPSDATE BETWEEN '2007-10-23 11:21:00.859' AND '2007-10-23 17:00:00.062' AND GPSDEVICEID = 0x004A08BC04050000;
6.03401924005389E-06
// Std Dev is a numerically stable computation, although it does require traversing the dataset twice.
//
// This calculation is not being done correctly.
//
// Incidently, SQRT(VAR(Latitude....)) gives 4.80354E-4, which is also way off.
I will redefine STDEV to use a stored procedure similar to the above, but the algorithm used to compute VAR, STDEV etc should be reviewed and fixed.

I have quite a few tables which allow NULL values. I have to struggle a lot with DBnull Exceptions :|example: col1,col2,... are all columns of type Integer and possibly NULL. var query = from person in table select new { person.col1, test = (int?) person.col2, person.col3, person.col4, ...}; As soon as my result encounters a DBNull value.. the whole query fails. This is really bad.How would I return the valid values.. and set the keys where there is no value to a null type? (e.g. int -> 0)I tried using "(int?)" but I'm not *really* sure what it does :-) Anyway.. it has no effect :-)
View 1 Replies View RelatedI wonder if anyone can help with this. I have searched around and not found much on the topic which can resolve my problem.
History on the reason for using VBA and not C# or VB or VB.net etc. Whn I arrived at this company, there were no development tools so had to resort to Access and VBA. Of course, the routines I wrote are now set in production and I haven't had much time to convert them to c# and ASP.NET (which I have learnt over the past couple of years).
Anyway the problem is that I found on the SQLDTS.com site that I could in fact create and execute DTS packages within VB and followed the examples and got this working in VBA. Of course I created the DTS first and then saved it as VB, then used the resulting code with the VBA project etc etc. This worked well and we were happy.
The DTS packages I create and execute are to export data from SQL2000 tables to tabs in Excel spreadsheets.
Now I find that on my machine, when the objPkg.execute command runs, the Excel file is created but only the query column headings are populated into the excel file. No data is returned.
If I run this on a different machine it works (although having said that, the other machine is now starting to display similar behaviour on some routines).
we created a version of the Access 2000 MDB in Access 2003 some time ago and the Access 2000 still behaves correctly. The strange thing is that my machine has only started doing this incorrectly a little while ago (not sure how long now but could be as little as a couple of months). The routines are monthly processes so it's only going to show up as a problem once a month so the fact that it used to work on my machine and has only failed the last couple of times means that something must have changed on my setup. I am runningXP-Pro SP2 - fully patched, Office Pro 2003 and talking to SQL 2000 SP3a
is it possible that some windows updates or office updates are clobbering something which used to work?
If I allow the VBA to create the DTS but not execute it, I can execute the created DTS manually from SQLEM and it outputs data correctly.
No security access to the SQL databases/table has changed, nor have there been any changes to security on the file system where the files are written.
It's weird.
Any help would be gratefully accepted.

We run std 2008 r2. I haven't looked at my friend's function closely yet bur he showed me that when he selects from the function with one column and the same where clause he uses on same func with select *, he gets no data under the column he requested.Â
But when he selects * he gets a single row.
I took a peek and see a bunch of left joins followed by a bunch of outer applies in his func. I suppose (thinking out load) if anything random like the order of rows returned or sql decisions on how query runs can affect his function, that might explain it. Â
I'm running SQL Server 2008 Feb08 CTP and I've got a tablix with column groupings and row groupings which works nicely, I'm a becomming a big fan of the tablix.
However sometimes the filter I have on a column group returns no records and the whole column group disappears.
Is there any way to make this column appear with but with empty cells as I have another tablix down the page with the same columns and I want the columns to all line up on the multiple tablix.
In Version 2005 I used to achieve the equivalent of a column group within a table by adding a list with filter to the cell, this meant the column always was shown, the tablix allows does this much more elegantly but I'll have to go back to the old method if I can't make the column remain.
Am I just missing a simple option?

I'm using a bit-wise comparison to effectively store multiple values in one column. However once the number of values increases it starts to become too big for a int data type.you also cannot perform a bitwise & on two binary datatypes. Is there a better way to store the binary data rather than int or binary?
