To Determine Tables Are Null.
Apr 30, 2008Hi,
There are many tables in a database. Most of them are null(unpopulated). Perhaps there are hundreds of tables.
Can you please provide me a simple way?
Thanks

Also, when restoring a database, is there a trace flag you can use to force restore details to be written to the error log?

Database Tables And NULL Fields
Nov 17, 2006Hi there,
I have a fairly generic question regarding database design.
I am working on my first database using SQL Express.
I am testing the database by inserting records into the pre defined tables.
Sometimes I forget to input text into a non null field. When
this happens it displays an error and then skips a few rows
which makes my row numbering messy. For example say I have
Row 1, Row 2 Row 3 all nicely formatted but on Row 4 I make a mistake
this row then disapears and their is gap between 3 and 5 where 4 was.
Although I am just testing, I was wondering what happens in a real
scenario if an inexperienced data input person makes a few mistakes it
makes the database numbering systems look bad. In this case
is it common to make most fields NULL to allow for admin errors??
Joined Tables - Count And Null Values
Jan 11, 2014I joined different tables and got a result like this:
result | process | goal | date |
------- ---------- ------ -----------
ok | process4 | 1 | 12.10.2013
bad | process1 | 2 | 13.10.2013
ok | process1 | 4 | 12.12.2013
good | process4 | 1 | 03.01.2014
ok | process1 | 3 | 10.04.2013
bad | process3 | 6 | 09.01.2014
bad | process4 | 3 | 30.12.2013
best |NULL| NULL
Now I want to count the results by counting the processes and group them by the result.
But it should be count the latest result per process only, e.g. for goal "1" just "good" at 03.01.2014. I solved that with a subquery (date=SELECT MAX(...)..).
But now the result "best" disappears, because that column has no date.
Secondly I want to count results for a specific process, e.g. for process4. Every goal has max. one process, with different dates. But one process could have more than one goal.
I want to have this result for process4:
count | result
------ -------
1 | good
1 | bad
0 | ok
0 | best
But I got only:
count | result
------ -------
1 | good
1 | bad
I have tried a lot, but nothing works.
The whole result (best, good, ok, bad) are stored in an other table and I joined it.
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
Specifying Null Character For Loading Tables Using Bulk Loader
Jun 26, 2007Hi All,
my dba folks are coming back with an answer to a question that sounds strange and I thought I would check on here.
Situation.
We are using an ETL tool I developed to move data around and building a DW on 2005. In some cases we are using the bulk loader to load and in some cases the tool itself.
One of the defaults of the tool is to truncate trailing blanks....and so fields that contain only blanks get truncated to a zero length character string.
When reloading the data with the tool it carries a null indicator next to the field value so the zero length character string is loaded as not null.
When loading with the bulk loader the dbas are telling me that the field is translated to a null. Note that they want some fields translated to null so they are using the keepnulls parameter.
On other databases (and built into the tool because this is so) the bulk loaders usually allow the specification of the load statement at column level and the specification of a 'null character sting' to be translated to null if this string is found. I put an example below.
I seem to recall that SQL Server 7 had some sort of bulk loader that allowed specification of columns at column level......for example offsets or whatever and the specification of fields to be interpreted as nulls. (Though that was a long time ago.)
I have searched through the manual and I don't see an option there any more to specify a character that will be interpreted to a null by the bulk loader.
Is it possible in 2005 to specify a character such that when the bulk loader sees it the field will be set to null?? And not just set fields to null which are not present in the load file?
(Just by the way, we are going to make the truncate trailing blanks optional and it's easy....it's just that I thought this kind of null if option was available in 2005 and I am keen to know if it is not there, either gone or never was...)
Thanks in Advance and Best Regards
Peter

NULLIF Keyword
Use the NULLIF keyword after the datatype and optional delimiter specification, followed by a condition. The condition has the same format as that specified for a WHEN clause. The column's value is set to null if the condition is true. Otherwise, the value remains unchanged. NULLIF field_condition
The NULLIF clause may refer to the column that contains it, as in the following example: COLUMN1 POSITION(11:17) CHAR NULLIF (COLUMN1 = "unknown")
Transact SQL :: Comparing Two Tables By NOT NULL Cells In Different Columns
Oct 22, 2015We have two tables:
Table1
Servers|Databases|Users|Names
Server1|Database1|User1|Name1
Server2|Database2|User2|Name2
Server3|Database3|User3|Name3
Server4|Database4|User4|Name4
Server5|Database5|User5|Name5
Table2
Servers|Databases|Users|Names
NULL |Database1|NULL |Name1
NULL |NULL |User1|Name2
NULL |NULL |NULL |Name3
Server5|Database5|NULL |NULL
I need to check Table1 by Table2 only on NOT NULL cells and if all of them in the row match do not return that row as the result. In this case it will be:
Results:
Servers|Databases |Users |Names
Server2|Database2|User2|Name2
Server4|Database4|User4|Name4
I used query like this:
SELECT a.Server, a.Databases, a.Users, a.Names FROM Table1
EXCEPT
SELECT ISNULL(b.Server,c.Server), ISNULL(b.Databases,c.Databases), ISNULL(b.Users,c.Users), ISNULL(b.Names,c.Names) FROM Table2 AS a, Table1 AS c
But for many rows (like 100 000) it takes ages to get results, any better way to work on this?
Nested Join To Return Only Rows With Null Values From All Tables
Oct 17, 2007
Hello,
I have this INNER JOIN that is fine to show all possible combinations. But I need to show only rows that have one or more Null values in tbIntersect.
Should I use nested LEFT JOINT? How?
This is the SQL statement:
sSQL = "SELECT DISTINCT tbCar100.Car100_ID, tbCar100.Description100 AS [Caractéristique 100], " & _
"tbCar200.Car200_ID, tbCar200.Description200 AS [Caractéristique 200], " & _
"tbCar300.Car300_ID, tbCar300.Description300 AS [Caractéristique 300], " & _
"tbCar400.Car400_ID, tbCar400.Description400 AS [Caractéristique 400], " & _
"tbCar500.Car500_ID, tbCar500.Description500 AS [Caractéristique 500], " & _
"tbCar600.Car600_ID, tbCar600.Description600 AS [Caractéristique 600], " & _
"tbCar700.Car700_ID, tbCar700.Description700 AS [Caractéristique 700], " & _
"tbProducts.Prod_ID, tbProducts.PartNumber AS [Part Number] , tbProducts.Description AS [Description] , tbProducts.DateAdded AS [Date] " & _
"FROM tbProducts INNER JOIN (tbCar700 INNER JOIN (tbCar600 INNER JOIN (tbCar500 INNER JOIN (tbCar400 INNER JOIN (tbCar300 INNER JOIN (tbCar100 INNER JOIN " & _
"(tbCar200 INNER JOIN tbIntersect ON tbCar200.Car200_ID = tbIntersect.Car200_ID) " & _
"ON tbCar100.Car100_ID = tbIntersect.Car100_ID) ON tbCar300.Car300_ID = tbIntersect.Car300_ID) ON tbCar400.Car400_ID = tbIntersect.Car400_ID) ON tbCar500.Car500_ID = tbIntersect.Car500_ID) ON tbCar600.Car600_ID = tbIntersect.Car600_ID) ON tbCar700.Car700_ID = tbIntersect.Car700_ID) ON tbProducts.Prod_ID = tbIntersect.Prod_ID " & _
";"
Here is the content of the tbIntersect table:
Car100_ID Car200_ID Car300_ID Car400_ID Car500_ID Car600_ID Car700_ID Prod_ID ID
1 1 1 1 1 1 1 1 1
1 2 1 1 1 1 1 19
1 3 1 1 1 1 1 20
I need to return the rows that have null data, ex: second row because Prod_ID is NULL and third row because Car300_ID is NULL. In fact I need the data from the other joint tables that correspond to these ID fields.
Thanks
Huge Tables: Minimizing Row Size - Remove Null Bitmap
Apr 21, 2007I am in the process of designing a SQL 2005 database with tables that may hold several hundreds of millions of rows.
Due to various constraints, I am trying to save as much space as possible by optimizing the size of a row. Currently one row contains the following columns:
byte(4), byte(3), byte(3) = 10 bytes.
Adding 4 bytes for the row header, plus 3 bytes for the null bitmap (as described in BOL) I am ending up with 17 bytes/row. In a real world test it was an average of 18.3 bytes/row.
There are no indexes, no primary key and all columns are not NULL. Hence my question: since no column allows a null value, is there a possibility to "remove" the 3 bytes Null Bitmap?
Is there any other way to shave off one or two more bytes by using a clustered index etc?
Thanks

Subscription Issue With Null Default Parameter - Key Cannot Be Null
May 3, 2007I 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
Returned SQLParam.SqlValue Is {Null} But Can't Test For Null?
Nov 5, 2007I 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!!

WITH RETURNS NULL ON NULL INPUT Not Working?
May 3, 2006Hello.
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?
Transact SQL :: Database Null Value And String Null
Oct 27, 2015We 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"?

View 1 Replies View RelatedHow To Determine Cause Of Timeout?
Aug 3, 1999Good day,
We have a web application (ASP) running on SQL Server 7.0.
Recently, the users are getting quite a lot of timeouts on
the database:
Microsoft OLE DB Provider for ODBC Drivers error '80040e31'
[Microsoft][ODBC SQL Server Driver]Timeout expired
The database is not supposed to be doing too much work, so I can't
understand why these timeouts are occuring. How can I determine
the cause of the timeouts?
The cause could probably anything from a trigger that's taking
too long, a query that's taking too long, or simply bad database design.
I've looked at SQL Server's Profiler, but could not yet use it
successfully to give me any hints of what could cause the timeouts.
Any ideas of how I can use Profiler, Performance Monitor, or any other
tool(s) to see what is happening in the background in the database,
i.e. how much processing a trigger is using, etc.
Thanks very much!

Jul 20, 2005I've been doing a lot of reading on this and my head is starting tohurt! It seems to be quite a feat to work out how much memory isactually being used by our server.I'm running W2K advanced server with SQL 2000 EE, 8GB of RAM, a min of4GB and a max of 6GB is assigned to SQL server.I'm trying to work out whether we've assigned enough or toomuch/little memory to SQL server. My first thought was to let SQLdymanically manage its own memory and see how much it uses, of coursewhen AWE (/3GB /PAE) is enabled it will just use all that isavailable.In perfmon "target server memory" = 6.1GB, "total server memory" =6.1GB, "total pages" = 768000 ( x 8KB = 6.1GB).My second thought was to use "total pages" - the average "free pages"= average mem used, therefore giving me the average amount of memoryused by SQL. I found out that SQL uses a min of 4GB (the min weassigned) and the max of all the memory, 6GB.Is there an easier way of finding out how much memory is actually usedin this situation or is going by the above average the best way?What i'm unsure about is will SQL just use all memory assigned to ituntil it has the whole DB in memory? 20GB including indexes etc....Any help would be greatly apprechiated.

Determine That This Is Deterministic
May 3, 2008Hi all... This is the definition on the M/S site:
"Deterministic functions always return the same result any time they are called with a specific set of input values and given the same state of the database. Nondeterministic functions may return different results each time they are called with a specific set of input values even if the database state that they access remains the same."
Good... straight forward, right? Ok.... try entering thses command seperately:
Create Table Readings (ReadingDate DateTime Not Null);
Create Function [dbo].[funct_SameDate](@datReadingDate Datetime)
Returns DateTime
As
Begin
return @datReadingDate;
End
Alter table Readings add
[TempColumn] as (dbo.[funct_SameDate](ReadingDate)) PERSISTED NOT NULL;
Error on last command returns:
Computed column 'TempColumn' in table 'Readings' cannot be persisted because the column is non-deterministic.
Can someone please explain this to me? The same value is always being returned.
This does work:
Create Table Readings (ReadingDate DateTime Not Null);
Alter table Readings add [TempColumn] as (ReadingDate) PERSISTED NOT NULL;
I obviously want to do more things inside the function, but I can't get by the first step.
Any suggestions?
Thanks!

Determine First Row Of New Page
Dec 27, 2007Hi,
I have a report that has a table with detail grouping. This table shows the sales by day for each product. The users only want to see the date field for the first item in the group. After that, they do not want to display this field (to reduce the data on the report). However, when the data wraps to a second page, they want the date to appear on the first row of the new page.
Is there any way to determine if a row is the first row on a page?
I tried using the RowCount, but that continues from the previous page.
Any thoughts?
Thanks!
David.
