Hi Everyone,
I have a query
select name, address, city from table1
I want to append address +'-' + city in this query . I want to show hyphen only if both address and city are not null. If name is null then I don't want to show hyphen. How can I get around this problem.
Any help will be appreciated.
Thanks,

I have a table that I know has a null or nothing in a field. When I run this query to get a list of them nothing comes back at all but it doesn't error out. Any ideas?
select *

order by lab_test_conf_id
Hi,
How can I check in a conditional split for fields not null? I see where I can use the isnull() function but I need to check for is not null.
Hi All,
I would like an example of checking for NULL within an expression. I don't know the correct syntax. Checking for IsNull is incorrect so is IS Null. Can anyone help me?
Hello, I am using sql server 2000 as my backend.If there is any null record in my table , I am getting following error:*********** Conversion from type 'DBNull' to type 'String' is not valid. ************** to overcome this error I want to check if its null then don't do anything else do something.I have tried like this:If rs.fields("ph").value="NULL" thenelse.................end if But this does not solve my problem.Please help me i anyone can.Thanks.

View 6 Replies View RelatedWhat would be an equivalent expression for ISNULL(datafield, 0) for a table/matrix cell?

There was a similar question to mine a few time ago about conditional execution, but I'm having some problems with it to which I couldn't find any answer, could anyone help?
My condition is checking if a DateTime from a DB table is null. I use the Execute SQL Task to retrieve the record (SELECT TOP 1 * FROM myTable WHERE conditions = TRUE), then I map 2 fields to their respective global variables.
Then I created the green arrow connector and used a precedence expression based on sucess. I used the expression IsNull(@variable). For some reason, even if the @variable comes as null - I checked the info in the DB - it still comes out as '1999-11-30'
I've looked around and the IsNull method can be used to also change the value in the event of it being null, could it be changing my variables value to this even if I didn't pass that value as a parameter to the function? If so, how else can I test it for null? I've tried "== null", "= null" and even ".equals(null)" - which I know is absurd, but I'm running out of options here...
Could you enlighten me, please???
Thanks in advance!

I'm wanting to create a if statement that will query a table and check for a duplicate and if there is a duplicate return that uniqueID or if it doesnt find a duplicate continue to add a new record...so here is my question is there a way to run a if statement that will call a function (lets say a function that returns like a bool) and if it finds a duplicate grab that id and store it in a session.....i guess my question is how do i query the database for a record and if found return true if not return false....that is my question....

I searched through the forums thinking this may have been brought up before, but I cannot find a post the directs to my problem.
I have a lookup table (lookup.os) which defines various operating systems. It has a "OSID" field which is just a primary key numbering, a "OSInstr" field which is used in a 'like statement' in a cursor used later on and "OSName" which is the full name of the OS.
ID| BROWSERNAME | INSTR

2 | Windows 2003 | Windows+NT+5.2
3 | Windows Vists | Windows+NT+6.0
.....
19 | Unknown Operating System | <blank>
I have a cursor loop that goes through another table (tblIISLog_ALL_OS) and searches through the instr of the (lookup.os) table to add to a stats of a third table (statistics.os). It works fine going through the loop, except there is a problem with the last value in the (lookup.os) table. If the value does not match the rest, it will select value "19 - Unknown Operating System" which is correct, but if the value is null it will not be selected. I take it 'NULL' >< a blank like statement. Here is what I have now. I am open to suggestions of what I should do. I was thinking maybe removing the "19 - Unknown Operating System" from the (lookup.os) table and after the first cursor loop has run, run it again and everything remaining it will just put in as "19 - Unknown Operating System". What do you think?

Hello,I have a table which contains some nullable columns. I want to write asingle query, which can be prepared (ie. prepared statement), that canhandle null or non-null values for the where clause. Is this possiblein a standard-conforming manner?The simple for of the query is this:SELECT * FROM <table> WHERE <column> = <value>But when the value to be matched on is NULL, the syntax of the querymust change to be:SELECT * FROM <table> WHERE <column> IS <value>In the second case <value> is NULL.I know one option might be to change the ANSI NULL handling option,but I am loathe to do this (I have five RDBMS's to support, not justMSSSQL).I thought I might have been able to cheat using an IN clause to makethe SQL consistent, but no luck.ThanksKevin

I have an sql table which contains a number and a name. I would like to create a select statement that will display these two fields in the format :
"number | name", but if there is a null value in the number it will display only the name and vice versa.
How can I do it ?
Any help is appreciated.
Code below:
SELECT
NAME,

If I am switching the NULL values to hyphens (-), why am I not getting any records when I look for hyphens in the WHERE clause? The script is not as simple as this or else I would just check for NULL values. I really need to switch NULL values to something I can pass on to a variable and query on it from Reporting Services.

declare @somesql nvarchar(20)
execute sp_executesql @somesql, N'@lnCurrRow int', @lnCurrRow = 1
PRINT @@ERROR
@@Error returns 0, which is seems incorrect since @somesql is null. If you substitute @somesql for the constant NULL then an error is fired. The above also executes successfully with @@error = 0 if you set @somesql = '' (empty string).
EXEC behaves the same way.
It makes sense that executing an empty string should be fine, but NULL? Is there a SET option available that will cause an error to be raised if sp_executesql attempts to execute a nvarchar variable that's set to NULL?
Thanks.
In ssrs, I want to display a column "Actual Value", which is a currency field.

On my aspx page I have a basic sqldatasource and gridview - both were set up using the wizards. The SQL Server 2000 database table that the sqldatasource is querying has some fields in it that are set to not allow nulls, however, the gridview control is not displaying all of the fields in the table - including some of the non-null fields.
My problem is, when I run an insert on the table from my aspx page, I get an error that says: "Cannot insert the value NULL into column 'ColumnName', table 'TableName'; column does not allow nulls. INSERT fails. The statement has been terminated."
The 'ColumnName', as you may have guessed, is one of the aforementioned columns that doesn't allow nulls, but isn't in the GridView.
How can I do an insert on this table without messing with the non-null fields. Those fields are relevant to the purposes of the gridview, so I don't want to display them, let alone allow editing of them.
Any suggestions on my options would be greatly appreciated!
Thanks

I am attempting to update a table that drives a report. The report is at the order level. An order can have several types of demand (revenue $): Ship and/or Backordered. When I update one of these demand fields on the report table, I would expect those orders that have that type of demand to update, and those orders that don't have that type of demand to remain at their current value ($0 in this example which is the table default). But what is happening is that orders that don't have that type of demand are changing to NULL. What am i doing wrong with my update statement that is causing this?
Code:
CREATE TABLE #sales(
OrdNo int,
StatusGrp varchar(10),
Demand decimal(10,2)
)
INSERT INTO #sales
VALUES (1,'Ship',100.00)

I am working on a Function that takes multiple parameters. I have a query that populates a temporary table, and then it processes some logic. My question is, if the parameter is passed as null, I dont want the query to be affected by this null value. Rather, I would like to not pass it at all to the query. So if the parameter is NULL, dont pass it through the query. I have the following but its not compiling right:
SELECT bom.pEngr_BOM_ID , bom.fEngr_Item_ID, det.pEngr_BOM_Detail_ID, 1, bom.Bill_Type, bom.Rev_Ltr, bom.Series_Ltr
FROM dbo.Engr_BOM_Control bom WITH (nolock)

WHERE bom.pEngr_BOM_ID=@v_pEngr_BOM_ID
AND det.fEngr_BOM_ID=@v_pEngr_BOM_ID
CASE WHEN @v_Bill_Type IS NOT NULL THEN
