Any expression containing a null value will evaluate to null.

There are a couple of ways around this. You could define your database columns so that they are not allowed to contain null values, and assign them a default value of zero.

Another method would be to test each value for null, and use 0 for the value of that operand if the result is true.

Hope that helps.

Could try something like:

COALESCE(x,0) + COALESCE(y,0) + COALESCE(z,0) as [Row Total]
FROM .............

Please stop reposting questions. People have already told you how to do this with linked servers. If you don't want to use linked servers (and to be honest, I can't see any reason why you wouldn't), you should reply to them on that post.

the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer

Deja View - the feeling that you've seen this post before.

In SQL Server IDENTITY property is the equivalent of the oracle's sequences. IDENTITY property can be set to the columns of the types tinyint, smallint, int, bigint, numeric, decimal. It is used in the form of IDENTITY(seed, increment)
Example,

CREATE TABLE abc(
f1 int IDENTITY(10,2), 
f2 varhar(100)
)

Also have a look at this[^] for more details.

SQL Server text column question

Hi - I just have a general SQL server question I'm hoping someone can help answer.

I have a table with a column of datatype TEXT called NOTE. I am trying to trim those records in the text field to say, 10000 characters where datalength(NOTE) > 10000.

for example, normally i would do something like 'update notetable set note = LEFT(note, 10000) where length(note) > 10000', but of course i can't do this with this datatype.

This datatype is a pain..Does anyone know the syntax for this?

Thanks!

No - it'll still ultimately reside in the same column - I just need to trim it.

any thoughts?

I don't see why what PIEBALDconsult suggested will not work:

select cast(mytextcolumn as varchar(1000)) as MyTextColumnTrimmed from mytesttable

Try it out.

I guess I misunderstood the suggestion.

However, I did:

select cast(NOTE as varchar(16349)) as NOTE
from S_NOTE_ACCNT
WHERE datalength(NOTE) > 16349

and I get:

The size (16349) given to the type 'varchar' exceeds the maximum allowed for any data type (8000).

So really, I need to trim the field to 16349, but apparently I can't this way...any thoughts?

I don't have the data to test with but, I do believe that SUBSTRING works with the TEXT & NTEXT data types.

UPDATE
    noteTable
SET
    note = SUBSTRING(note,0,10000)
WHERE
    DATALENGTH(note) > 10000

Thanks, that works. - Apparently I didn't look hard enough. I guess I didn't realize that substring existed. I tried substr and when that didn't work, I guess I thought that that function didn't exist.

Thanks again!

Questions about various DB connection methods

Hello All,

I am looking to get some guidance and feed back from the community as to the prevalence and usage of the following technologies:

ODBC Descriptor support
OLE DB support
External Linked Server support
Data Link support for Data Transformation Services

Specifically I am hoping to find out when each technology should be used and the types of applications that use them. Additionally, I am wondering if there are alternatives to these technologies and why they may have been used instead.

Any guidance/feed back is appreciated.

Thanks,

How do I format this...

Steven J Jowett19-Dec-06 4:43

19-Dec-06 4:43

I have a stored procedure that can select data from several tables/views. One two of the parameters are DateTime fields. The SQL code is as follows :-

EXEC(N'SELECT * FROM ' + @objectName + ' WHERE DepotId = ' + @DepotId + ' AND [TIME] >= ' + @StartTime + ' AND [TIME] <= ' + @FinishTime + ' AND Intake = ' + @Intake + ';')

I am getting a error regarding the time parameters. I need to know how to format these for the where clause to work.

I have tried enclosing in double-quotes e.g. [TIME] <= "' + @StartTime + '" AND ...

I have also tried enclosiing hashes e.g. [TIME] <= #' + @StartTime + '# AND ...

neither works, please help

Hi - As the subject lines suggests - can we do this in SQL 2005?

suppose I have a function_A - does certain calculations.

CREATE another_function_B<br />
(@driver int)<br />
RETURNS int<br />
AS<br />
BEGIN<br />
 declare @output as int<br />
   -- checks some certain type of conditions and then executes function_A<br />
   select @output = dbo.function_A(@driver)<br />
 return  @output<br />
END

I did - it didn't get any results, which it should have. that is why decided to post a message.

I tried to debug the 'function' by using print statements but looks like that doesn't work. How could we write some debug statement?

Verify each item outside the UDF. That way you will see if it actually returns data.
