Using SQL Query Analyzer how do I do something like:
WHERE columnName = 'this' AND anotherColumnName IS NOT NULL
I.E.
SELECT *
FROM CES_DATA
WHERE DIV = 'MW'
AND Not IsNull RO
ORDER BY RO
how to select all column names from sql whose columnvalue is '1' for a specific user
Howdy all,I'm trying to create a sproc that has the column name and search text as input parameters with dynamic SQL... what I have is:-- Create a variable @SQLStatementDECLARE @SQLStatement varchar(255)SELECT @SQLStatement = 'SELECT * FROM myTable WHERE (''' + @ColumnName + ''' = ''' + @SearchText + ''')'-- Execute the SQL statementEXEC(@SQLStatement)The procedure works (at least in Query Analyzer, once I declare/set @columnname and @searchtext) in that I don't get any errors. But it returns a blank table with "0 rows affected". However, if I hardcode the variables, it returns the proper data. What's wrong with my select statement?? Thanks!!JP

What is the difference between
<Tablename> . . <ColumnName> and <Tablename> . <ColumnName>
this syntax we are using in Storedprocedures.
In SQL 2000, <Tablename> . . <ColumnName> is not working
Eg:
Tablename =a
Column Name = b
Difference between a..b and a.b
Can anyone let me know.
TIA,

Hi
I know the answere is out there, but i cant find it.I would like to have a dropdownlist in my webpage (asp.net/vb.net) to have values dynamicly collected from my database.The values should be the ColumnName of all columns i have in a speciall table.
How can i make the dropdownlist to have the ColumnName from every column i the table?My sqlcommand looks like this down under but i would like me.ColumnName to be a ColumnName value.New SqlCommand("Select * from tblmytable where " & Me.ColumnName & " = 'true'", myConnection) Greatful for help!/ Mitmit
I want to dynamically determine which column I select data from. The table I want to select from looks like this:tblSexualitySexualityID int PKEN nvarchar(20)NL nvarchar(20)DE nvarchar(20)Based on the value of variable @LanguageColumnName I want to select the value from either column "EN", "NL" or "DE"In the sample below the value of @LanguageColumnName is "NL".Unfortunately the value of sexualityname is ALWAYS: "tblSexuality.NL" and not the value from that specific column...how can I alter my procedure so that it does the select the value from that column?ALTER PROCEDURE [dbo].[spFindUsers]@LanguageColumnName nvarchar(3),@startRowIndex int,@maximumRows intASBEGINSET NOCOUNT ON;

Hello all,
how can I select one or more columns from a table by column-index and NOT by columnname?
e.g.:
SELECT tbl1.[1], tbl1.[2], tbl1.[3] FROM Orders AS tbl1
and NOT like this:
SELECT tbl1.OrderNo, tbl1.ProductNo, tbl1.Price FROM Orders AS tbl1
Is that possible in MS-SQL 2000?
Thanks a lot in advance
kind regards

Hi folks, I have a little challenge for you, I hope :)
The short story is as follows: I have multiple rather well normalized tables, and a view which connect them all togheter. In one of the tables I have an xml column, which I in the view to varchar(4000), since SSIS doesn't like xml all that much. To make the view updateable I have an instead of trigger placed on it, which works quite perfectly from T-SQL. SSIS however, claims that I cannot insert to a read-only column. Does anyone have the slightest idea how I can get around this?
The only solution I can think of is having two columns for the XML data, one as varchar and the other as varchar, then having a trigger updating the xml column when the varchar is updated, but that would require recursive triggers, which I am not too happy with.
Cheers
I have created a SSIS pkg (datasource and flat file destination)
I need to have the flatfile renamed after each exec to a column name that exists in the table I am running the pkg against.
Where does the code get put to make this change after the file has been created?
Basically if I could run T-SQL after the file creation, I could make it work.
thx..
Hey. 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
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.
Is it possible through SSRS designer?
Is there a difference in performance when using count(*) or count(columnname)?
View 10 Replies View RelatedI have a flat file with the following columns
SampleID Rep_Number Product Protein Fat Solids
In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.
SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.
I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help
Key cannot be null. Parameter name: key
I run a stored procedure for which I have a return variable. The stored procedure returns the ID of a row in a table if it exists:
m_sqlCmd.ExecuteScalar();
The m_sqlCmd has been fed an SQLParameter with direction set to output.
When the stored proc returns, I want to test it. Now when there IS a row it returns the ID ok.
When the row doesn't exist, in my watch I have:
m_sqlParam.SqlValue with value {Null}
I can't seem to work out how to test this value out.
I've tried several things but none seem to work.
This line compiles ok, but the following runs into the IF statement as if the SqlValue is null??
if (m_sqlParam.SqlValue != null)....
{
// I'm here!! I thought the watch says this is null???
}
Sorry if this is obvious, but I can't work this one out!!
Looks like there was a fix and then I read this fix is not a fix. Does anyone know how this can be rectified? Does it mean that only Windows authentiation is the only way it works. The Software is over 2 years old, there are no excuses.

Hello.
I've built a sample CLR function with the following declaration....
CREATE FUNCTION GetManager(@DeptCode nvarchar(3))
RETURNS nvarchar(1000)
WITH RETURNS NULL ON NULL INPUT
AS
EXTERNAL NAME Assembly1.[ClassLibrary1.MyVBClass].MyManager
And it works as expected, except when I use NULL:
DECLARE @MyManager nvarchar(1000)
EXEC @MyManager = dbo.GetManager NULL
PRINT @MyManager
It returns the value "Unknown" as it would have for any unknown DeptCode, as-programmed.
I'm of the theory it should have returned NULL without actually firing the function? Or is this only for non-CLR items... or stored procedures, not functions?
We have a case where in we should show date based on conditions for e.g if we had a column defined as
col varchar(10) then we would show col as 'NULL' for some condition and actual value when no condition
Normaly date values are stored here e.g under col 20150901 .
Case
when col>'20150901' then 'NULL'
else col
end as Derivedcol
Note this is an extract process and we are presenting data by pumping the data in a table .
Now there is another similar column -colz varchar(10) which stores date but doesnt have case condition so whenever date has no value its shows null which is database null.
So whats the difference between database null and string null ?
How can we show database null for the case condition instead of string "null"?
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.
Appreciate your help

Hi guys,
I've got a query on a particular table returning an odd result:
SELECT DISTINCT WorkStation
FROM Invoice
WHERE WorkStation Is Not Null
ORDER BY WorkStation
This query returns the rows I'd expect plus a null row. This doesn't happen in databases at other sites, or in other tables at this site. The following query behaves as I'd expect returning only non-null AccountNumbers.
SELECT DISTINCT AccountNumber
FROM Suppliers
WHERE AccountNumber Is Not Null
ORDER BY AccountNumber
I can't reproduce these results on another site on a table of the same structure, or on another table at this site.
Any suggestions as to what might be going on?

I have 595 default constraints in my database. I can return a list of them using the following:
select * from sys.default_constraints
Is there a way I can return a list of just the ones where NULL is still allowed? I want to update all of the columns with a default value to not allow NULLs.
Dear folks,
please tell me the query for altering a column from not null to null

Hi all,
One of my columns is the table has some Null values, and I Would like to stop having NULL values into that column any more.
I know, If I alter the column to NOT NULL will throw me an error, since it does a batch update.
Is there any way to achieve this...
Thanks...
ok here is a WIERD issue.
I've NEVER EVER had this issue, I have always done this and it works great both locally and remotely.
I have a table, which is a "customers" table.
I have a stored procedure which takes in parameters (name, address, password etc...) and returns me back, via a parameter declared as output - the customer ID.
I've always done this, and works great.
Now, this works fine locally.
IF I try to run this/do the exact same execution of commands (create a customer) remotely (where the database is stored, so copying everything from local to "over there") it does not work.
I get a DBNULL value back from the parameter, declared as an int output.
IF I copy and paste this Stored procedure Query/command into Query Analyzer and execute it (on the remote connection) and run it, giving it the exact same values as I do, it works perfect and returns me the correct value.
I've even dropped and recreated the stored procedure but makes no difference.
Any ideas why?
here is the proc....
CREATE PROCEDURE [dbo].[DoCreateNewCustomer] (
@theFirstName nvarchar(25),
@theLastName nvarchar(25),
@theAddress nvarchar(50),
@theCity nvarchar(15),
@thePostCode nvarchar(9),
@thePhoneNumber nvarchar(21),
@theMobilePhoneNumber nvarchar(21),
@theIPAddress nvarchar(25),
@thePassword nvarchar(50),
@theEmailAddress nvarchar(30),
@result int output
)
AS
SET @result = (SELECT [ID] FROM Customers WHERE emailAddress = @theEmailAddress)
IF @result IS NOT NULL
SET @result = -1
ELSE
BEGIN
SET @result = @@IDENTITY
INSERT INTO Customers (
Firstname,
Lastname,
Address,
City,
Postcode,
PhoneNumber,
MobileNumber,
IPAddress,
[Password],
EmailAddress
)
VALUES (
@theFirstName,
@theLastName,
@theAddress,
@theCity,
@thePostCode,
@thePhoneNumber,
@theMobilePhoneNumber,
@theIPAddress,
@thePassword,
@theEmailAddress
)
END
GO
Any ideas why it does not work when calling the stored proc from either a web app, or through QA remotely but works fine when I run that command in QA or locally?
Again, if I do:
EXEC DoCreateNewCustomer { params } - the output result it gives me is DBNULL (if on remote connection)
If I do this locally, perfect
If I copy and paste pretty much the SP into QA and execute it on the remote connection, works great, and also locally.

I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?

Hello everyone,I have a table that stores data of a Person. For personal data, there are 2 different fields, for example... a personal address and a professional address, a peronal email and a professional email, a personal phone num and a professional phone num, etc...My question is, i would like to know if it's possible to make it for at least one of these fields to be NOT NULL, but not necessarily both.I'll have 2 fields: emailPersonalemailProfessional Can i make it so that, when inserting or updating data, sql checks to see if AT LEAST ONE of the emails is filled in (both can also be filled in)... I dont care which one is filled in, as long as ONE is filled in... Thanks in advance,SuperJB

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.
