Required Field Empty - How Could This Happen?
Feb 21, 2008
Hello! I have a web form in VB.NET & ASP.NET 1.1, with data being saved to a SQL 2005 database with multiple tables. The primary key on all these tables is a unique identifying number that the user enters. However, one record in this database (across all tables) has no identifier. All other information seems to have saved without problem, but there's no identifier, which is very wierd for several reasons: 1) the form should not allow the user to proceed without it; 2) all the tables in the database do not allow nulls for the column, and 3) it's the primary key!
Any thoughts on how this might have happened?
Thanks!

I have a report with a fixed header that works properly when the query returns results (or fixedheader = false). However, when the result set is empty, I get tenacious client-side "object required" errors. Obviously I can either turn the fixedheaders off or disable debugging in IE, but is there a Microsoft fix for this problem?

I have a column being added with VB.net, but I can't figure out the syntax. I get the error No Value given for one or more required parameters. But no clue which one. Below is the code I am attempting.

I added a new field to an existing ETL process which uses SSIS to ingest a CSV file. The new field in the file, Call_Transaction_ID, will not always be populated for every record and so can be NULL or empty for certain records.
Here's the problem:After the file is extracted into a staging table, the Call_Transaction_ID field is showing blank or empty when it has no ID for that particular record. The problem is when I try to then ETL this data into a fact table - I'm trying to set the Call_Transaction_ID field to -1 if it is NULL or empty, however SQL Server doesn't see the field as empty even though there is no value in the field so -1 will NEVER return.
Using a WHERE DATALENGTH(Call_Transaction_ID) = 0 returns 0 records, again because SQL Server doesn't see the field as empty or NULL.
What do I do now to get around this? How do I fix it?

$message = "Missing data - please try again" ;
header("Location: registration.php?message=$message");

I'm trying to do a simple update like I have done countless timesbefore.However, when I update the empty fields in this table it places a -1into the field rather than the enterred value.It is indexed with duplicates allowed. It says that zero lenght isset to yes.What can I do about this?if Request.form("ouserid") <> "" Thenvar2 = " and userid = '" & Request.form("ouserid") & "' "Elsevar2 = " and userid is null "End ifif Request.form("orepid") <> "" Thenvar1 = " repid = '" & Request.form("orepid") & "'"Elsevar1 = " repid is null "End if"Update [Website Settings] set userid = '" & REquest.form("userid") &"' and repid = '" & Request.form("repid") & "' where " & var1 & var2& var3Thanks!

Hello...
I am going crazy trying to figure out how to do this. I have a flat file which I am massaging the data and loading into a table here is an example of a line out of the flat file:
"ABC NUTRITIONAL PRODUCTS","550","","","N","FAIR OAKS","","","COLORADO SPRINGS","C0","","","","","","","","A","","",""
My problem is that I have one field which is this address in a concatinated form. The fields that do not apply to this entry are suite#, floor# and other columns which are designated by the "" characters. The final concatinated addres field looks like this:
"550""""N""FAIR OAKS"""
I would like to remove the "" characters in the concatinated string. I just don't know the best way to do this? I was told DTS had a way of removing the "" from the flat file source. Since I have not used DTS extensively I am not sure if this is true. I was wondering how in SSIS I could go about removing the "" marks without removing the "" say if someone is quoted eg. John said "This is only a test". Removing the quotation marks in this instance would be changing the data. I am not sure how to do this and any help or advice is greatly appreciated!
Thank you...

How can I pass into the database (@User_fax = null) if the fax form field is empty, from a command type Stored Procedure? For example:
Dim CmdUpdate As New SqlCommand("Form2_NewUser", strConnection)
CmdUpdate.CommandType = CommandType.StoredProcedure
CmdUpdate.Parameters.Add("@User_fax", SqlDbType.char, 9)
CmdUpdate.Parameters("@User_fax").Value = fax.Text()
...
strConnection.open()
CmdUpdate.ExecuteNonQuery
strConnection.close()
And, the stored procedure inside Sql server:
USE market1
GO
ALTER PROC Form2_NewUser
@User_id bigint, @User_fax char(9),...
AS
SET NOCOUNT ON
UPDATE Users
SET User_fax = @User_fax, ...
WHERE User_id = @User_id
SET NOCOUNT OFF
GO

So I have an MDX query in an SSRS data set. Here is my MDX query:
Code SnippetSELECT { [Measures].[Gross Sales Amount USD], [Measures].[Net Sales Amount USD] } ON COLUMNS, { ([Promotion].[Media Property].[Promo Code Description].ALLMEMBERS) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( SELECT ( STRTOMEMBER(@BeginDateConvert, CONSTRAINED) : STRTOMEMBER(@EndDateConvert, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( STRTOSET(@PromotionMediaProperty, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( { [Promotion].[Campaigns].[Campaign].&[Paid Partner] } ) ON COLUMNS FROM ( SELECT ( { [Products].[Product Line].[Line].&[Merchandise] } ) ON COLUMNS FROM ( SELECT ( { [BusinessUnit].[Business Unit].[Product Business Unit].&[40] } ) ON COLUMNS FROM [Net Sales]))))) WHERE ( [BusinessUnit].[Business Unit].[Product Business Unit].&[40], [Products].[Product Line].[Line].&[Merchandise], [Promotion].[Campaigns].[Campaign].&[Paid Partner] ) CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS
This query returns 4 fields. Media Property, Promo Code Description, Gross Sales, and Net Sales. For the given query the measures are empty or null. I do not want any data to show up when the measures are null so I put in NON EMPTY clauses before the COLUMNS and before the ROWS. So now my query looks like this: (I only added the NON EMPTY clauses)
Code Snippet
SELECT NON EMPTY { [Measures].[Gross Sales Amount USD], [Measures].[Net Sales Amount USD] } ON COLUMNS, NON EMPTY{ ([Promotion].[Media Property].[Promo Code Description].ALLMEMBERS) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( SELECT ( STRTOMEMBER(@BeginDateConvert, CONSTRAINED) : STRTOMEMBER(@EndDateConvert, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( STRTOSET(@PromotionMediaProperty, CONSTRAINED) ) ON COLUMNS FROM ( SELECT ( { [Promotion].[Campaigns].[Campaign].&[Paid Partner] } ) ON COLUMNS FROM ( SELECT ( { [Products].[Product Line].[Line].&[Merchandise] } ) ON COLUMNS FROM ( SELECT ( { [BusinessUnit].[Business Unit].[Product Business Unit].&[40] } ) ON COLUMNS FROM [Net Sales]))))) WHERE ( [BusinessUnit].[Business Unit].[Product Business Unit].&[40], [Products].[Product Line].[Line].&[Merchandise], [Promotion].[Campaigns].[Campaign].&[Paid Partner] ) CELL PROPERTIES VALUE, BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING, FONT_NAME, FONT_SIZE, FONT_FLAGS
Adding the NON EMPTY returns nothing... not even field names. This is a problem because, I have a table in the report that looks at this data set and when there are no fields, the report can't run.
How can I still have NON EMPTY functionality and still show the fields? Is this a problem in SSRS?

Greetings,
I have several reports for which the user has asked to have an optional muti-value parameter. They want to be able to select zero, one, many, or all values in the parameter list. The parm list is created through a query and the values are not static.
I would like to allow the user to leave the muti-value field empty if they want to allow all values to appear on the report. I've read some discussion about populating a multi-value default with the same query that produces the multi-value list values - presto, everything is selected. However, this is not a desirable solution for me because I "echo" the users parameter selections in the report heading. Selecting all values (and some parms have a lot of values) would cause the "parm feedback" section to grow large and unreadable.
In short, I don't want to tell the user they have to select everything when they really want to select nothing.
Is there any way to have a muti-value parm that won't insist the user select one or more values?
Thanks,
BCB

i have a trigger on a table right now... when fields are inserted, theres a text field inserted and i want to check if that text field = '' (the empty string, not NULL) and if it doesn't equal that, then perform some row updates on other tables, but if it is empty, to not do anything else in the trigger... right now i have this:
Code:
IF ((SELECT Note FROM XATPoDetail WHERE ReqNbr = (SELECT ReqNbr FROM Inserted)) LIKE(''))
Note is the text field, XATPoDetail is the table where its being inserted into. I had to do the select FROM the table because it wouldn't let me select a text data type from the "Inserted" virtual table
but it tells me me "Error 279: The text, ntext, and image data types are invalid in this subquery or aggregate expression"
thanks

I have a requirement where i have to insert empty string in column whose datatype is decimal.
I have to replace the column value if it is null then insert it as ' '.
Obviously its generate error msg for conversion, is there any workaround for this. I cannot add 0 or other value as this column is used to generate some output value.
IIF(Column1 IS NULL, ' ', Column1))
I used TRY_PARSE but it insert null value if there is conversion error.

Hi,
What is the difference updating a null value to char/varchar type column
versus empty string to char/varchar type column?Which is the best to do and why?
Could anyone explain about this?
Example:
Table 1 : tCountry - Name varchar(80) nullable
Table 2 :tState - Name char(2) nullable
Table 3 :tCountryDetails - countryid,state (char(2) nullable) - May the country contain state or no state
So,when the state is not present for the country ,i have two options may be - null,''
tCountryDetails.State = '' or tCountryDetails.State = null?

What would happen if I deleted all the contents of the tables like MSmerge_*.
In case it needs to be known, we have a merge-replication scenario with about 25 servers under SQL 2000 SP3.

For instance, say the date of an update is : 16/10/2007 15:16:03 I want the Label to say "Happened over 2 months ago" etc.Now ive tryed to use an IF statment but I cant seem to get it right : DateTime dt = Convert.ToDateTime("16/10/2007 15:16:03"); if(dt.ToShortDateString() == DateTime.Now.ToShortDateString()) { //happened today if(dt.ToShortTimeString() == DateTime.Now.ToShortTimeString()||dt.ToShortTimeString() < DateTime.Now.AddMinutes(-1).ToShortTimeString()) { //happened within a minute UpdateLabel.Text = "About A Minute Ago"; } } else if (dt.ToShortTimeString() == DateTime.Now.AddDays(-1).ToShortTimeString()) { //happened yesturday UpdateLabel.Text = "Updated Yesturday"; } else if (dt.ToShortDateString() == DateTime.Now.ToShortDateString() || dt.ToShortDateString <= DateTime.Now.AddDays(-7).ToShortDateString()) { UpdateLabel.Text = "Updated Last Week"; }Any ideas where Im going wrong?

Hi,
what will happen in the following occasion?
checkpoint --> begin tran --> system failure
In MOC (SQL 7.0 Implemetation), it says there will be rollback, but in my humbel opinion, there should be nothing happened.
I think there was no dirty writing in this case. No data pages written, no log
pages written to disk. Am I right? Then, there might be nothing happened
instead of ROLLBACK.
If I am wrong, would you please let me know what is wrong in my thougt?
Thanks in advance,

I am using SQL Server 6.5, when two or more independent applications put transactions through SQL, it locks up. Example of locks up.
When the OrderLines table is locked, then I put the following (Select * from OrderLines) then the query does not return any values, the world goes round and round, the only way out is to shut down and cross my fingers whilst SQL goes into recovery mode.
I have read through some of the documentation, such as deadlocks, livelocks and lock starvation but it say none of these will lock the whole machine. But somehow simultaneous transactions can, and the current activity dialog goes red, bright red.
Any ideas?

I have a SQL 2000 server(sp2) on Win2000 SP2. My largest database is about 5 gig. Log shipping went astray and had to reinitialize. WHen I did the part where it actually backups the init db to disk failed with the following
3041 :
BACKUP failed to complete the command BACKUP DATABASE [Development] TO DISK = N'G:SQLBACKUPdevlog' WITH INIT , NOUNLOAD , NAME = N'Development backup', NOSKIP , STATS = 10, NOFORMAT
In the NT event log I got the following
{Lost Delayed-Write Data} The system was attempting to transfer file data from buffers to DeviceLanmanRedirector. The write operation failed, and only some of the data may have been written to the file.
MS had an article on this
http://support.microsoft.com/default.aspx?scid=kb;en-us;293842.
There solution is Win2000 SP3. Has anyone had these errors before.

HiWe have a SQL 2000 (sp3) server with a database that I set up to have theMDF on D: and the LDF on E:. All was going along fine for several months andone day the server rebooted. The SQL log says something like "Service isshutting down due to server shutdown."When it came back up the LDF File was on D: (in the same folder as the MDF).The original LDF was gone from E:The SQL Log doesn't ever say anything like "Recreating LDF in defaultlocation." or any anything else that would explain what happened.I assume the change happened during the reboot (actually I didn't notice ituntil a week and a half later). I am relatively sure no human did anythingthat caused the log file to move.So has anyone seen this happen before.?TIA-Dick

Hi everyone,
I'm relatively new to SSIS - i've played with the technology a little and i've created some DTS packages previously.
I'm in a scenario where I have 3 servers with an instance of SQL 2005 installed. Server A is a live server with lots of statistical data, Server B is a backend server specifically provided for handling heavy data processing. Server C is another live server, but it's essentially empty.
I would like to transfer some data from Server A, summarise it using the processing power of Server B and then store the resulting summary data in Server C. One of my main requirements is to have minimum processing performed on Server A and C.
I created an SSIS package which produces the required results, but I've no real idea where the hard work is being performed. For example, in my SSIS i have an OLEDB data source which uses a select statement with a couple of parameters to determine which data to return from Server A, i then have an aggregate transformation on the output before an OLEDB data destination for Server C. So where does the aggregation get performed?
Im hoping because i'm running my SSIS package on Server B that in the above instance, all the source data is pulled onto Server B (maybe into a tempdb?) and then aggregated by Server B before then being transferred onto Server C.
Please let me apologise in advance for the lengthy post - but just trying to explain this to others may help me work it out in my head (at the very least)
thanks,
Andrew

Hi,I am trying to debug some queries that are being generated by anexternal program, and I have no way of finding out what the actualsyntax of the query is from within the program itself. This means thatwhen the query fails I am left with only a very unhelpful message.So what I was wondering, was whether there is a way that I can view theactual queries that are sent to SQL server as they happen, or if areal-time solution doesn't exist, then some way I can look back afterthe event and see the syntax of the queries?Ideally, what I would like to do is see the queries in the form theywere sent to the server, ie "SELECT * FROM foo WHERE bar='foobar'", asthis would help me to figure out where the generated queries are goingwrong.Cheers,--Dylan Parryhttp://electricfreedom.org | http://webpageworkshop.co.ukThe opinions stated above are not necessarily representative ofthose of my cats.

Ok, here is my situation.....
When someone navigates to a user's profile page on my site, I present them with a slideshow of the user's photos using the AJAX slideshow extender. I obtain the querystring value in the URL (to determine which user's page I'm on) and feed that into a webservice via a context value where an array of photos is created for the slideshow. Now, in order to create the array's size, I do a COUNT of all of that specific user's photos. Then, I run another SQL statement to obtain the path of those photos in the file system. However, during the time of that first SQL query's execution (the COUNT statement) to the time of the second SQL query (getting the paths of the photos), the owner of that profile may upload or delete a photo from his profile. I understand this would be a very rare occurrence since SQL statements 1 and 2 will be executed within milliseconds of each other, but it is still possible I suppose. When this happens, when I try to populate the array, either the array will be too small or too large. I'm using SqlDataReader for this as it seems to be less memory and resource intensive than datasets, but I could be wrong since I'm a relative beginner and newbie. This is what I have in my vb file for the webservice.....Public Function GetSlides(ByVal contextKey As String) As AjaxControlToolkit.Slide() Dim dbConnection As New SqlConnection("string for the data source, etc.") Try dbConnection.Open() Dim memberId = CInt(contextKey) Dim photoCountLookupCmd As New SqlCommand _ ("SELECT COUNT(*) FROM Photo WHERE memberId = " & memberId, dbConnection) Dim thisReader As SqlDataReader = photoCountLookupCmd.ExecuteReader() Dim photoCount As Integer While (thisReader.Read()) photoCount = thisReader.GetInt32(0) End While thisReader.Close() Dim MySlides(photoCount - 1) As AjaxControlToolkit.Slide Dim photoLookupCmd As New SqlCommand _ ("SELECT fullPath FROM Photo WHERE memberId = " & memberId, dbConnection) thisReader = photoLookupCmd.ExecuteReader()
Dim i As Integer For i = 0 To 2 thisReader.Read() Dim photoUrl As String = thisReader.GetString(0) MySlides(i) = New AjaxControlToolkit.Slide(photoUrl, "", "") Next i thisReader.Close() Return MySlides Catch ex As SqlException Finally dbConnection.Close()
End Try
End FunctionI'm trying to use the most efficient method to interact with the database since I don't have unlimited hardware and there may be moderate traffic on the site. Is SqlDataReader the way to go or do I use something else? If I do use SqlDataReader, can someone show me how I can run those 2 SQL statements in best practice? Would I have to somehow lock writing to that table when I start the first SQL statement, then release the lock after I execute the second SQL statement? What's the best practice in this kind of scenario.
Thanks in advance.
