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
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)
AND DR.languageid = isnull(@inlanguageid,null)
AND DR.[ID]= @ID
)
go
set ansi_nulls on

T-SQL (SS2K8) :: Change A Selected Value To Null?
Dec 1, 2014I am emailing data using this:

Our systems stores 01/01/1753 when the date field is blank. In the above TSQL, how can I replace 01/01/1753 with null or blank in teh results?
How To Return Number Of Selected Rows From All Queries Performed On DB
Feb 20, 2013Recently I had an application developer approach me and asked if I could provided him with a list of sprocs by returned row count. We had an issue where the application passed in a number of parameters which attempted to return 200k plus rows of data and the application was timing out. He changed the required parameters in the application and a reasonable number of rows were returned as expected. Short term solution to this one problem.
However there are always timeout issues with this particular application and we got to thinking that maybe other sprocs that were called using parameters would also fail at some point in time because too much data was being returned.

SELECT With NULL Values In One Or More Of Selected Columns
Apr 10, 2008Hello everyone,
I have a little problem here. I need to select data from multiple columns and multiple tables, some of those columns can have NULL value. I have tried few things, and havent find the right way so far. Problem that i am incountering is that when i run SELECT statment as it is right now, i dont get back results which match search parameters but have NULL value in one or more column in select statment. How can i fix this problem?
SELECT Person2role.person2roleID,Person.firstname, Person.lastname, Person.sex
FROM Person LEFT OUTER JOIN
Person2Role ON Person.personID = Person2Role.personID
WHERE (Person.firstname LIKE '%' + ISNULL(@firstname + '%', ''))
AND (Person.lastname LIKE '%' + ISNULL(@lastname + '%', ''))
AND (Person.sex = ISNULL(@sex, Person.sex))
This is a part of SELECT statment..just so you can get the idea of what i am doing..i have few more parameters
I am working with SQL Server 2005 Express Version

Reporting Services :: How To Display (All Selected) When Parameter (Select All) Is Selected In SSRS
May 6, 2015Using SSRS 2008 r2...I have a report with a single-value parameter and three multi-value parameters, Class1, Name2 and Name3. I'm hoping for an explanation to one thing that I'm seeing and information on a second thing.
Class1 and Name2 both have the (Select All) parameter selected but Class1 is displaying the concatenated parameter variable list whereas Name2 is showing Null. Why is that? If anything, how can I get Class1 to be similar to Name2 and show Null?But my desired wish is to have Class1, Name2 and Name3 display the text"All Selected" when the parameter (Select All) is chosen.

Return NULL Value
Sep 6, 2005I am working on a web application for a company that uses an existing company database. I just found out before the long weekend that a couple hundred of the items in the table aren't completely related.
I am mostly using 2 tables for the project: ItemVersion, ItemVersionRev
ItemVersion has fields: ItemVersion, ItemNumber, RecordID
ItemVersionRev has fields: RecordID, RevNumber
All of the items in the database have ItemNumbers (obviously) and most have revision numbers (RevNumber). One of the functions that I created for my application finds the MaxOfRevNumber. I ran a query on the database and saw that dreaded error screen that read "There is no row at position 0"
The query that I have now simply returns MaxOfRevNumber. Is there a way to program a query to check and see if an ItemNumber has a Revision and depending on the result, return a certain value. For example, if there is not a corresponding RevNumber, then return 0 as the RevNumber?
Null, Not Null SQL Return
May 22, 2003Hello all
I am trying to run a sql statement, (without having to run stored procedures), that will lookup a value stored in a Record.field., otherwise ignore the value if it is blank. I have a field tied to a Microsoft Access form - ItemLocation. If the user selects a unique ItemLocation the report will attempt to locate all values within that ItemLocation. If the user decides to leave the field blank, I would like for it to return all values for every ItemLocation. If anyone can help, I would really appreciate it. I will attach code. My problem is the last line of this SQL statement. If F.ITemLocation is null, I get no data. I would like for it to return everything. Thank you.
Code:
SELECT DISTINCT

Xp_cmdshell Always Return 'null'

I tried just running EXEC master..xp_cmdshell 'dir ' and it worked, so I am certain it is not a SQL rights problem.
FYI, I executed the same code on another machine and it worked. I just cannot figure out why it is not working on this one server?

Return Null Results
Mar 24, 2004Hi,
I have this problem with MS SQL Server.
I have this table 'Request' in which there's 2 fields 'RequestName' and 'DateSubmitted'.
The datatype for 'DateSubmitted' is datetimn.
I have to write a query to extract all the 'RequestName' that falls under each month based on the 'DateSubmitted'.
For example, the table 'Request' has 12 rows, each row ('DateSubmitted') with the month of the year. Like row1 = January, row2 = February etc.
For each month, I have to extract all the 'RequestName' for that month based on 'DateSubmitted' field.
My query is like this:
select RequestName, datename(month, DateSubmitted)as month
from Request where datename(month, DateSubmitted) = 'March'.
By right it should return just one row right?
Instead, it returned me all 12 rows, only one row with value 'March' and the other 11 rows with value 'NULL'. Even if the other 11 rows have value of other months, when i run the above query, it will return me null.
Any help is appreciated.
thanks a million.
Return A Row With Null Values?
Apr 19, 2014I am trying to return all the names of employees and their managers
this query returns all the employees except for 1
SELECT E.FNAME,E.LNAME,M.FNAME,M.LNAME
FROM EMPLOYEE E,EMPLOYEE M
WHERE E.SUPERSSN=M.SSN
the one that isn't returned has a null SUPERSSN, but when I add in:
OR E.SUPERSSN IS NULL
it returns a row with the name of the employee whose SUPERSSN is null 8 times (where each time the M.FNAME,M.LNAME are other employee names)
How do I ammend the first query to return each employee and their respective manager once, the employee without a manager having null values for the manager name columns?

View 2 Replies View RelatedCan @@ROWCOUNT Return NULL?
Aug 29, 2005SQL Server 2000 SP3.Is it possible for the @@ROWCOUNT function to return NULL after astatement? I am troubleshooting a relatively large stored procedure withmultiple SELECT statements and a couple of INSERTs into table variables.Immediately after each statement I save the value returned by @@ROWCOUNT toa local variable. That information eventually is passed back to the clientvia one output parameter, for all statements in the procedure.Occasionally, the value returned via that parameter is NULL. This cannot bereproduced by re-running the SP with the same input parameters.Before doing any further troubleshooting, I would like to rule out thepossibility that @@ROWCOUNT can actually return a NULL under somecircumstances. From searching the archives, it appears that in SQL Server7.0 this could happen in the context of a DML query on a table withtriggers. This is not the case here - the only DML queries are INSERTs intotable variables, all other queries in the SP are SELECTs.Any related information would be appreciated.--remove a 9 to reply by email

'@NumericVal IS NOT NULL' Seems Not To Return A Boolean.
Jul 4, 2007I'm trying to ensure that only of the parameters is passed to my stored procedure.

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'

Oracle Acquire Connection For Ssis Return Null
May 16, 2007Hi All!
I'm writing a custom component in c# for SSIS and I have a problem with AcquireConnection...
I wrote this code:
public override void AcquireConnections(object transaction)
{
if (ComponentMetaData.RuntimeConnectionCollection[0].ConnectionManager != null)
{
ConnectionManager cm = DtsConvert.ToConnectionManager(ComponentMetaData.RuntimeConnectionCollection[0].ConnectionManager);
ConnectionManagerAdoNet cmAdo = cm.InnerObject as ConnectionManagerAdoNet;
if (cmAdo == null)
throw new Exception("The ConnectionManager " + cm.Name + " is not an ADO connection.");
this.conn = cmAdo.AcquireConnection(transaction) as OracleConnection;
}
but the 'conn' is ALWAYS null...
I tried
this.conn = ((IDTSConnectionManagerDatabaseParameters90)cmAdo).GetConnectionForSchema() as OracleConnection;
too, but no result: the 'conn' is null again...
If I use oledbconnection or sqlconnection instead of oracleconnection the method works fine... I really don't understand
could you help me plz?
