I am trying to create a stored procedure where.I need to loop through every row of the table and check if there exists a date in either of the column. If date exists in either of the column for every row, I need to update some other stuff.For the above table, it meets my requirement, so I need to update. However if the table is as below, it doesn't meet the requirement, so I don't need to update
I am looking for the best way to check to see if any columns are still NULL in a record. I have a form that gets filled out by users and the values entered into TableA. There are 6 columns in the table, 5 are responses and column6 indicates if the record is complete. So I want a way to see if all of the first 5 columns are NOT NULL and, if so, mark column6 with a 1.
I am thinking this would be a good thing for a trigger on INSERT or UPDATE to check to see if the first 5 columns are filled in and then mark the record as complete.
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.
Hi I have two tables. one MasterDetail and second is countrydetail In master detail i have MasterDetailId (Primary) and countryId. In CountryDetail table I have Countrid (Primary),CountryName. I don't want to give relationship because i can insert null value in countryid in MasterDetail table. So i have wriiten query like this -> select c.CountryName,m.MasterDetailId from MasterDetail m,CountryDetail c where c.CountryId=m.CountryId and m.MasterDetailId= '2' If In MasterDetail table if CountryId is null then it will not show me any record. So I want that record and its value with this query and checking null values. Help me about solving this query. Thank You
I am trying to create a stored proc. I have to check a parameter for null value and if null then set it to zero Here is the stored proc set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go ALTER PROCEDURE [dbo].[UPDATENOA] ( @Accepted char(10), @NOAId bigint, @Court char(30), @RetainerType char(30), @PendingInTaxCourt char(1) ) AS begin UPDATE NOA set StageCode = Accepted,Court=@Court,RetainerType=@RetainerType,PendingInTaxCourt=@PendingInTaxCourt where NOAId = @NOAId; Declare @Sequence int Select @Sequence = MAX(Sequence) From [dbo].[NOAStages] where NOAId=@NOAId; if @Sequence IS NULL { @Sequence=0 } Insert into [dbo].[NOAStages] (NOAId,StageCode,Sequence) values (@NOAId,@Accepted,@Sequence+1) But this is giving me error. What is the correct way to do this. Thanks
I have two columns A (which allows nulls) and B( which does not allow nulls). How can I add the contents of columns A and B SO THAT I DO NOT GET A NULL RESULT WHEN A IS NULL.
The result of A+B concatanation will be stored in a column, C.
SELECT whatever_field, CASE LEN(DrAccount) WHEN 12 THEN DrAccount ELSE CASE (Note1) WHEN NULL THEN Location + DrAccount ELSE Note1 + DrAccount END END AS Account FROM Table1 The purpose of the CASE(Note1) is when Note1 column is null, return Location+DrAccount. The actual result is when Note1 column is null, it always returns null, Location+DrAccount is not executed. When Note1 column is not null, it returns correctly Note1+DrAccount. The problem seems to reside in validating the null value in WHEN NULL How to check for null in CASE(fieldname) WHEN ???
the SQL string below worked, and then started bringing up every record. it should only select records with a value in at least one of the columns, but it apears to be suggesting that all records have some data in one of the columns. if I check the database or the output on the web page there apears to be no data. ?? confused.
"SELECT id, make, model FROM vehicles WHERE workToBeDone1 IS NOT NULL OR workToBeDone2 IS NOT NULL OR workToBeDone3 IS NOT NULL OR workToBeDone4 IS NOT NULL OR workToBeDone5 IS NOT NULL"
Any ideas how I could implement this more robustly? cheers M
hi guys, I'm using SQLServer 2005 and I was wondering how I check if some variable is null or not? I tryied to do as the code show but it doesn't work:
declare @number int
set @number = (select number from numbers where number_id = 1)
Okay, I have the following statement for my store procedure:
Code Snippet IF exists (SELECT [ID], [title], [name], [issueID] FROM [Outlook] WHERE ([issueID] = @OLissueID)) SELECT [ID], [title], [name], [issueID] FROM [Outlook] WHERE ([issueID] = @OLissueID) ELSE SELECT null ID, 'No parent page yet' title FROM Outlook
I wanted to put an ELSE IF statement right before the ELSE statement to check if the value is null. Something like this:
IF exists (SELECT [ID], [title], [name], [issueID] FROM [Outlook] WHERE ([issueID] = @OLissueID))
SELECT [ID], [title], [name], [issueID] FROM [Outlook] WHERE ([issueID] = @OLissueID) ELSE IF (SELECT [ID], [title], [name], [issueID] FROM [Outlook] WHERE ([issueID] = @OLissueID) != null
SELECT [ID], [title], [name], [issueID] FROM [Outlook] WHERE ([issueID] = @OLissueID)
ELSE
SELECT null ID, 'No parent page yet' title FROM Outlook
Or if this is possible, it's much better:
IF exists (SELECT [ID], [title], [name], [issueID] FROM [Outlook] WHERE ([issueID] = @OLissueID) AND (SELECT [ID], [title], [name], [issueID] FROM [Outlook] WHERE ([issueID] = @OLissueID) != null)
SELECT [ID], [title], [name], [issueID] FROM [Outlook] WHERE ([issueID] = @OLissueID)
ELSE
SELECT null ID, 'No parent page yet' title FROM Outlook
I don't quite get how to write the SQL statement that I wanted so any help is much appreciated.
I am using Visual Web Developer Express 2005 and SQL Server Express 2005. I have set up a trigger that fires when an update has been performed on a specific table. The trigger checks to see if specific columns have been updated. If they have, then the trigger code is executed. This part works fine. I am now trying to find a way to check if null values exist in either one of two field from the same table. If either field contains a null value, then I don't want the trigger code to be executed. How can I check for null values and skip a block of code within my Transact Sql trigger. Thanks.....
I'm about ready to pull my hair out. I have a repeater control, and a date field. If the field is a valid date, I'll use it to calculate and display the person's age. Otherwise, I want to display "N/A". My problem is trying to determine if the date field is null or not.I'm using SQL Server 2005 which allows Nulls in the date field, and for many records I don't have a birth date. It makes sense for these records to leave the date Null. This is my code:Protected Sub Repeater1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles Repeater1.ItemDataBound If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then Dim LabelIcon As Label = CType(e.Item.FindControl("LabelIcon"), Label) Dim LblAge As Label = CType(e.Item.FindControl("LblAge"), Label) Dim inmate As WAP.prisonmembersRow = CType(CType(e.Item.DataItem, System.Data.DataRowView).Row, WAP.prisonmembersRow) If System.IO.File.Exists(Server.MapPath("~/images/picts/" & inmate.FILE2 & ".jpg")) Then LabelIcon.Visible = True End If If inmate.DATE_OF_BIRTH Is DBNull.Value Then If IsDate(inmate.DATE_OF_BIRTH) Then LblAge.Text = "Age: N/A" Else LblAge.Text = "Age: " & GetBirthdate(inmate.DATE_OF_BIRTH) End If End If End IfEnd Sub How can I resolve this?Diane
declare @user varchar(30) = '' if(@user is not null or @user <> '') BEGIN print 'I am not empty' END ELSE BEGIN print 'I am empty' ENd
The output should be 'i am empty' but when i execute this i am getting ' i am not empty'. even i did browse through but i don't find the difference in my logic.
Hi!I have a table with a check constraint. But unfortunately it does notwork like I wanted.CREATE TABLE MAP([R_ID] [T_D_ID] NOT NULL,[R_ID1] [T_D_ID] NULL,CONSTRAINT CHECK_ID1 CHECK (R_ID1 = R_ID OR R_ID1 = NULL),CONSTRAINT [PK_MAP] PRIMARY KEY ([R_ID]))R_ID1 should always have the value of R_ID or NullThe following statements should cause errors:insert into map (R_ID, R_ID1)values(1,2);update map set R_ID1=3 where R_ID=1;But there occur no errors. Does anyone have an idea? It is an SQL Server2000.TIASusanne
Hi, I have a record set that is bound to a table in MS SQL Server. Onefiled in the table is bound to a "long" type member variable in theRecordSet. What will happen to the "long" variable when the field isNULL in the table?Thanks!-Yi
A report I maintain has an extensive footer that appears on each page, populated with information I've stashed into invisible cells in the table's header. This works great, except in rare circumstances where the report includes a page that doesn't display the table at all--in which case the report errors when it attempts to print ("Object reference not set to an instance of an object").
Due to the requirements of the report, I cannot guarantee that the table will appear on every page, every time. Is there a way I can safely refer to the reportItems collection, in case of Nulls? I'll be okay with blank values in the footer in the cases where the page has no reportItems to work with, but I can't have the report blow up when printing.
I have a column say 'ActivationDate' which is a (database timestamp [DT_DBTIMESTAMP]) which I want to replace with an expression in derived columns
The condition is if 'ActivationDate' field is null or '' then 'Null' else 'ActivationDate'
I am struggling to write this condition. Without condition i.e. at present it saves the value in this database '1753-01-01 00:00:00.000'. In the preview the 'ActivationDate'field does not show any thing so I recon it is either null or ''
I have a table that keeps track of all changes that were performed in an application. There is a column called "old value" and column called "new value". There are some values in the application that don't require data therefore the "old value" or "new value" values can be empty. These columns are an nvarchar data type because the value can be text or numbers or dates. An example is "ReceivedDate". There is a report that is generated based on this table.
What is happening is the query in the report dataset is adding dates when it should be displaying empty. They query is using "CASE/WHEN/THEN". What I need is "When the column is "RecievedDate" and it is not null then convert it to a date". This is for formatting purposes.
This is an example of the table:
UpdateColumn Old Value New Value ReceivedDate 7/8/2015 5:00:00 AM ReceivedDate 7/8/2015 12:00:00 AM 7/9/2015 5:00:00 AM ReceivedDate 7/9/2015 12:00:00 AM
So, the first time it was updated there was no value but it was replaced with July 8, 2015 and so on.This is what the report is displaying
This is the query:
CASE UpdateColumn ... WHEN 'ReceivedDate' THEN (replace(convert(varchar(11),CONVERT ( date, oldvalue ), 106), ' ', '-') ) ... I tried adding CASE UpdateColumn ... WHEN 'ReceivedDate' IS NOT NULL THEN (replace(convert(varchar(11),CONVERT ( date, oldvalue ), 106), ' ', '-') ) ...
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"

I have a case where if the Id field is a specific value, I don't want to allow null in another field, but if the Id value <> a specific value, null is ok.
In the example below, inserting the first record should succeed, the second should succeed, and the 3rd should fail. Right now the 2nd two fail. I gotta be missing something easy, but I can't figure it out.

I've got about 6 formats of flat files coming through data flows & heading into a relational db, then later to a data warehouse. In each file type, I've got about 60-70 columns to perform basically two levels of validations on - first is straight data type conversions, then 2nd is finer level stuff. Some of the data from each file type overlaps in other files, so for instance some lookup codes are maintained for both.
The data is pretty dirty, so I'm keeping everything as varchar coming into the staging area, just so I can get the data in the system, b/c the users demand on some form of of the data making it into the system, no matter the dirtiness.
So then I'm running my two steps - first converting data types from varchar to bit/datetime/int, etc. as applicable. And then , I'll be running finer levels of validation, doing range checks, etc. My question is - with so many columns, what's the most efficient & best way of doing all these checks in the data flow, and recording errors out of each check? Do I put one column check after another with the success constraint, do the lookup/range check/other, and then record the error if an error is encountered, then move on to the next column? Or would it be better to multicast out the stream to 60 flows and do all the needed checks, then union all the good stuff back together at the end? Anything to help save some headache - b/c this data is dirty and there's a lot of it.
I have an SSIS Package. I am using script component to loop through input columns and their values. I am not able to do Null checking. The code is as below. In place of dashes , I want to do null checking but am not able to do. I tried vbNull, IsNull, TypeOf, System.dbNull but nothing is working. I guess am missing something here. Can anyone help me with this.
