What's The Accepted Way To Retrieve Records In A SQL Table With Null Values Using A Visual Studio 2005 Table Adapter?
Jan 21, 2008I'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database.
I have a very simple dilemma. In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields.
It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table.
In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters.
The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%')
If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null>
My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>.
For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null> (accounting for about 95% of the records in the database). Thanks in advance Simon
Query To Return Records Where One Table Is Void Of Linked Data In Another Table
Feb 13, 2008I have two tables that share a common identity row. I need to build a query where data that exists in one table does not contain data in the other table. For example, table 1 has columns of Owner_ID, LastName, FirstName and table 2 has columns Auto_ID, Owner_ID, AutoMake. Both tables are joined by the Owner_ID column. I need a query that provides all owners from table 1 who do not have an entry in table 2.

Query Individual Records Within A Table
May 21, 2002Please can someone advise me on how I can create a statement that will query each individual row within a table.
As the data will vary month by month I'm unable to state the amount of rows that will need to be queried.
An Overview:
We have web-based application with a SQL back-end. When changes are made to a record a copy of that info is sent to another table (a quick snapshot, name, date, number, department etc.). At the end of the month I need to apply this data to an imported itemised phone bill so that I can make sure that if the mobile phone had been reallocated to another person I can change the cost accordingly.
As it stands the operator has to print a copy of the phone details before reallocating to another person. Then at the end of the month manually changes the data within the itemised bill by referring to the printouts. Ideally I would prefer to automate the whole process.
Please find below the script - its very much in its infancy!!
CREATE PROCEDURE sp_reallocate AS
select * from tbl_mobile_reallocate
order by allocation_change_date
update tbl_mobile_import
set empno = tbl_mobile_reallocate.empno from tbl_mobile_reallocate
where tbl_mobile_import.mobno = tbl_mobile_reallocate.mobno
and tbl_mobile_import.invoice_date <= tbl_mobile_reallocate.change_date
update tbl_mobile_reallocate
set status = 'Closed'

Query To Retrieve Records That Sum To A Field In Another Table

dbo.CorpAdv.AcctNum is text field

Enterprise Manager Cannot Display Table Records Or Run Query
Jul 23, 2005I have a new installation of SQL Server 2000 Dev Edition on a Win2K3 Standard Edition Server that I used for development. I just set this machine up in th last week and installed all Win2K3 patches and then installed SQL2K and SP3a. I have a single named instance. I just noticed today that I cannot view table data or use the Query part of EM. When I right click a table and select Open Table->Return All Rows it gives me an error dialog "An unexpected error happened during this operation". While the EM is diplaying this dialog the EM screen looks like Internet Explorer and says "Action Canceled - You might not have permission to view this directory or page using the credentials you supplied." I believe that this is a EM issue as I cannot view table content on other remote server. ANy ideas? Might this be an IE security patch disallowing some connectivity ?--Frank--Message posted via http://www.sqlmonster.com

The Records With Null Value
Oct 15, 2007
Hello,
I have a column called Prod_Class in a table. The data type is char(1) and allow null. The records have 3 distinct values ('E', 'P' and null) for Prod_Class in this table . When I run Select * from table1 where Prod_Class <> 'E', I expect I get the records that value equals to 'P' or is null. However, I only got records that the value equals to 'P'. If I run "Select * from table where Prod_Class <>'E' and Prod_Class <> 'P'", I got nothing while I expect I get the records that value is null. I know if I run "Select * from table where Prod_Class is null", I can get the records that value is null, but I need to know why I can not get result using "<>" and how to fix it. I am using SQL server 2005.
Thanks in advance for your help!

View 4 Replies View RelatedSearching For Records With Null Values
Oct 9, 2007I'm hoping someone can help me with my problem.
I'm reading in records from a 'flat file' and loading them into sql.
I have 5 values I'm loading in. I first check my sql db, if all 5 values match a current record in sql, I don't want to load the record, because it's already there. If it doesn't exist, I need to load it.
It works fine as long as none of my values are NULL. But if I have a record with a field, say Gender, that is null, if its a new record it loads fine, setting gender to NULL in sql. But then when I encounter another record, which is identical, I'm testing to see if it already exists by doing a 'select where Gender = @Gender' and it always returns that the record does not exist in the db - even though it exists (because its using the = instead of is null)!
I need some mechanism where if the value is null it tests 'Gender is null' but if there is a value, it tests gender=gender, [and I need this for all my parameters]. Or is there some other way to do this?
Here is my code for looking to see if the record exists:
public static int ExistInsured(int CaseID, object InsuredLastName, object DateOfBirth, object CurrentAge, object Gender)
{SqlConnection conn = new SqlConnection(connStng.ToString());
SqlCommand cmd = new SqlCommand("SELECT top 1 InsuredID from Insured Where PolicyID = (Select PolicyID from Policy where CaseID = @CaseID) and LastName = @InsuredLastName and DateofBirth = @DateofBirth and Gender = @Gender", conn);
int result = -1;
cmd.CommandType = CommandType.Text;cmd.Parameters.AddWithValue("@CaseID", CaseID);
cmd.Parameters.AddWithValue("@InsuredLastName", InsuredLastName);cmd.Parameters.AddWithValue("@DateOfBirth", DateOfBirth);
cmd.Parameters.AddWithValue("@CurrentAge", CurrentAge);
cmd.Parameters.AddWithValue("@Gender", Gender);
conn.Open();
try
{object ret = cmd.ExecuteScalar();
if ((ret != null) && (ret is int))result = (int)ret;
}
finally
{
conn.Close();
}return result;

How To Delete Records With A Field Containing NULL
Feb 9, 2008Hi,
All records of a table must be deleted if a field (field1) contains NULL or is made empty by a previous update command.
I did this but it only works when the field is made empty, not when it contains NULL:
dim field1 as string = ""...sql = "delete from mytable WHERE (field1=@field1)" comd = New SqlCommand(sql, oConnection) comd.Parameters.AddWithValue("@field1", field1) comd.ExecuteNonQuery()
How can i do that?
Thanks

Problem Viewing Records Having A NULL Value
Aug 27, 2005hello friends!

102| peter | NULL | yuba|
103| alex | plumber | yuba |
104| edward | NULL | yuba|
105| smith | carpenter| yuba|

I tried this stupid query ...
select * from test where skill = NULL
with this it is only showing me all the columns of my table
is there any query for my problem??
also
Is there any single query in query analyzer with which i can delete all the records having skill = NULL ?
Filtering SqlDataSource To Show All Vs. Non-null Records
Aug 29, 2006Hi -- I'm starting an ASP.NET 2.0 application which contains a page with a checkbox and gridview control on it. In its default state the gridview displays all the records from a table pulled from a SQL Server database (via a SqlDataSource object). When the user checks the checkbox, I want the gridview to display only the records where one of the columns is not null. But I've been unable to construct the WHERE clause of the SQLDataSource object correctly. I see that I can hard-code the SqlDataSource object so that the column to be filtered is always NULL or always NOT NULL. But I want this filtering to be more dynamic such that the decision to show all or non-null records happens at run-time. Should I be using two SqlDataSource objects -- one for the NOT NULL condition and one for the "all records" condition? Then when the user checks the checkbox, the gridview would be configured to point to the appropriate SqlDataSource object. (???) Seems like a bit of overhead with that approach. I'm hoping there's a more elegant way to get this done. Please let me know if you need more information. Thanks in advance. Bill

Parameter Issues When Returning Null Records
May 14, 2008Hi,
I'm running into an issue where if a report retrieves 0 records, I run into an error. My report has 2 queries-- the main query to retrieve Account information and the other to return Contact information based on the contact id(s) returned by the Account query. The reason needing two separate queries is that the contact and account tables are on different databases.
Now here is my account query: select contact_id, username, password from account.
My contact query looks like this: select name, address, .... from contact where contact_id = @contact_id.
In my report parameters, I define contact_id like this:
*******************************************
name = contact_id
data type = integer
prompt = [blanked out]
hidden = checked
internal = checked
multi-value = unchecked
allow null value = checked
allow blank value = unchecked
available values:
from query: dataset = account
value field = contact_id
label field = contact_id
default values:
from query: dataset = account
value field = contact_id
**********************************************
Now, when I run my report and knowing there are no records, I get the following error: "The 'contact_id' parameter is missing a value". Any ideas on how to solve this issue? Thanks.

Need Efficient Query To Partition Records By Type And Pull Top N Records From DB
Jan 18, 2008I have a query similar to the following. The intent of this query is to retrieve the top 6 records meeting the specified criteria (LOGTYPENAME = 'Process Status Start' OR LOGTYPENAME = 'Process Status End' ) based on most recent dates. Please keep in mind that I expect to return up to 6 records for each unique LogProcessName. This could be thousands of different LogProcessNames with up to 6 records for each.
1) The table I am executing against currently is very large in size and thus takes a long time to execute against. It would seem there must be a more efficient query to get the results I am looking for?
2) CTE doesn't work on SQL 2000. I need a query that does.
3) I cannot modify the database itself in the process.
;WITH cte AS (
SELECT [LogProcessName], [LogBody], [LogDate], [LogGUID], row_number()
OVER(PARTITION BY [LogProcessName]
ORDER BY [LogDate] DESC)
AS RN
FROM [LOGTABLE]
WHERE [LogTypeGUID] IN (
SELECT LogTypeGUID
FROM LOGTYPE
WHERE LogTypeName = 'Process Status Start'
OR LogTypeName = 'Process Status End' ) )
SELECT *
FROM cte
WHERE RN = 1 OR RN = 2 OR RN = 3 OR RN = 4 OR RN = 5 OR RN = 6
ORDER BY [LogProcessName] DESC, [LogDate] DESC
Does anybody else have any idea that would yield the results that I am looking for and take into account items 1-3 above?
Thanks in advance.
WHERE Clause On Nullable Field Not Return Null Records?
Nov 10, 2014I recently ran into an issue with an issue with a query against our Data Warehouse. When attempting to sum revenue from a table, and using a WHERE clause on a field that contains NULL values, the records with the NULL values are suppressed (in addition to whatever the WHERE clause specified). I believe this is because a NULL value is unknown so SQL doesn't know if it does or doesn't fit the criteria of there WHERE clause so it is suppressed.
That being said, is there a way to avoid this instead of having to add an ISNULL function in the WHERE clause which is going to kill performance?
Code:
create table #nullTest (
name varchar(50)
,revenue int)
INSERT INTO #nullTest
Values ('Tim',100)
,('Andrew', 50)
,(null, 200)
SELECT sum(revenue) as Revenue FROM #nulltest WHERE name <> 'tim'
Ideally, I would want the SELECT statement above to return 250, not 50. The only way I can think to accomplish this is with this query:
Code:
SELECT sum(revenue) as Revenue FROM #nullTest WHERE isnull(name,'') <> 'tim'

Select * from table1 where not exists (select * from table2 where table1.ID =table2.ID)
It will get the result as expected.
I just thought it would compare all the fileds for the outer query and inner query, but seems not. Why, I add a condition, it worked ?

T-SQL (SS2K8) :: Renumbering Remaining Records In A Table After Some Records Deleted
Dec 3, 2014I have a table with about half a million records, each representing a patient in my county.
Each record has a field (RRank) which basically sorts the patients as to how "unwell" they are according to a previously-applied algorithm. The most unwell patient has an RRank of 1, the next-most unwell has RRank=2 etc.
I have just deleted several hundred records (which relate to patients now deceased) from the table, thereby leaving gaps in the RRank sequence. I want to renumber the remaining recs to get rid of the gaps.
I can see what I want to accomplish by using ROW_NUMBER, thus:
SELECT ROW_NUMBER() Over (ORDER BY RRank) as RecNumber, RRank
FROM RPL
ORDER BY RRank
I see the numbers in the RecNumber column falling behind the RRank as I scan down the results
My question is: How to convert this into an UPDATE statement? I had hoped that I could do something like:
UPDATE RISC_PatientList_TEMP
SET RRank = ROW_NUMBER() Over (ORDER BY RRank);
but the system informs that window functions will only work on SELECT (which UPDATE isn't) or ORDER BY (which I can't legally add).

Problem With Isnull. Need To Substitute Null If A Var Is Null And Compare It To Null And Return True
Sep 20, 2006Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
