Now I want to Select the value of 2nd table in my Controle that is Dropdown and insert this value in the 1st table like bit. as this possible.
Thanks for helping.
What is the Datatype for NULL ? How SQL Server stores NULL ? I have seen many discussions on this. Some say's that NULL will be considered as character type, then what about NULL value comes in a number column ?
Another article say's NULL is untyped. It don't have any type. Which one is correct ? Will there any difference for NULL in SQL Server and Oracle ?
I'm using a table to hold data that I can pass back to the original form page and re-populate the fields that were not validated correctly. The stored procedure either inserts or updates the record in the temp table I've created.
So, currently, as I'm testing, I'm just passing empty values to all the parameters and the @state parameter is failing and throwing the error.
I've double checked that the table has the state column set to integer datatype
The column is set as follows:
Name datatype length Allow Nulls ---------------------------------------------- State int 4 checked
I have tried setting the default value for every column to Null in the table and then also not using a default value. Either way, I still recieve the same error?
Not sure what else to look at?
It seems the problem might be that instead of a null value being passed to the parameter that it is actually empty. Can passing an empty value to a column of datatype integer cause this problem? If so, is there a way to correct it?
1) it is in the same filegroup as the rest of the table? 2) it is stored in a filegroup separately from the rest of the table (I think this is allowed)?
Ok I have upgraded my works database from a poorly designed Access database to a SQL database. The previous system allowed NULL values and duplicates to be inserted into a field that should NOT ALLOW NULL Values or duplicates. Therefore, this issue has now been moved across to my new system as I cannot set these constraints on the field that has multiple NULL values.
My solution would be to use a sequential operator, so whatever = NULL would be changed to a sequential number that us as administrators would know was a bogus number starting at something like = 999999900 counting up from that. There are only 250 records that would require updating.
To make things more interesting this field is not a integer type, its a Nvarchar type as its a Hardware ID. Both numerical and characters are require.
In the below scenario we are inserting some time related fields in Temp table.But its data type is varchar. Once data loading is finished in the temp table (Data is loading by source team SQOOP and they are unable to load if the source datatype is having Date or datetime) we have to alter the column datatypes. somehow, some character data in inserted in date columns (look at into 3rd insert statement). while altering the table it is failing. Can we do any alternative for this (Means if any varchar data that is non convertible to date can we make as null)
INSERT INTO ##TEMP_TEST SELECT '2014-09-30','2017-10-06','Nov 6 2014 6:11AM','Nov 6 2014 6:11AM' UNION SELECT '2014-09-29','2017-10-06','Nov 6 2014 6:11AM','Nov 6 2014 6:11AM' UNION SELECT '2014-09-28','2017-10-06','Nov 6 2014 6:11AM','Nov 6 2014 6:11AM' GO INSERT INTO ##TEMP_TEST SELECT NULL,NULL,NULL,NULL
insert into scn_transaction (sourceSystemName) values(@sourceSystem);
SELECT @txOut = @@identity
Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).
I execute the stored proc with the following sql with an OLE DB connection manager:
exec sp_newTransaction ?, ?
The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:
The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.
At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.
I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.
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)
I have a field in a table that stores date of birth. The field's datatype is char(6) and looks like this: 091703 (mmddyy). I want to convert this value to a datetime datatype.
What is the syntax to convert char(6) to datetime?
HI,I have a table with IDENTITY column with the datatype as INTEGER. Nowthis table record count is almost reaching its limt. that is totalrecord count is almost near to 2^31-1. It will reach the limit with inanother one or two months.In order to avoid the arithmentic overflow error 8115, we would likechange the datatype from INT to BIGINT. we hope this will solve ourproblem.How do I approch this datatype conversion?. Since the data count ishuge, that leads to a long down time of database.we need better approach or solution for this problem?. kindly give mea better solution that will reduce the total downtime of the productiondatabase.?.Regards
i have so doubts in my mind and that i want to discuss with you guys... Can i use more then 5/6 fields in a table with datatype of Text as u know Text can store maximu data... ? acutally i am trying to store a very long strings values into the all fields. it's just popup into my mind that might be table structer would not able to store that my amount of data when u use more then 5/6 text datatypes...
and another thing... is which one is better to use as data type "Text" or "varchar(max)"... ? if any article to read more about these thing,, can you refere to me...
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.
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
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.
I am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.

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
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.
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.
