Greetings SSIS friends,
I have the following expression but it doesn't seem to evaluate
findstring(eventstatus, "O", 1) > 0 ? "OFF" : NULL(DT_STR, 30, 1252)
All I want to do is something like :
All I want to do is return a NULL value if my condition is false.
Your help would be appreciated.
I have null fields in one of the column and want to return "N/A" when the column is null. How can I do that ?

The code below returns the members who have accounts that are inactive, and works correctly.
It returns the memberid, but returns null values for the barcode values.
I am explicitly looking for unmatched rows, i.e. the LEFT OUTER JOIN will return joined member-address
rows which do not have a matching account, according to the ON conditions, and these are the ones I want
because of that WHERE condition.
Therefore account.barcode will always be NULL too.
Is there to perform the same query and return account details?
I have tried running a query to return just the memberid values and then perform a second query to match the account
details, but this is very ineffecient and slow.
select member.memberid, account.barcode
FROM member
INNER
JOIN address
ON address.MemberID = member.Memberid
LEFT OUTER
JOIN account
ON account.Memberid = member.MemberID
AND account.enddate >= current_date
AND account.closed = 0
WHERE account.Memberid is null AND member.isDeleted = 0
Special thanks to r937 for help.

I have a simple table on my webpage which shows data from my database.
It all worked fine apart from one part. I wanted the select statement to select only NULL values from a column, as these are classed as open queries. Once I have closed the query a 0 or 1 will automatically be posted and will no longer have a NULL value.
I have a simple select statement (which I will post on here when I log in with my work computer) and at the end I have a WHERE Column = NULL. I have also tried WHERE column <> 0.0 AND column <>1.0 and that did not work.
If I only did WHERE column <> 1.0, i only get the 0.0 results and none of the NULL results, but if I have no WHERE statement I get all the results including the NULL values.

Hi,
I have upgraded database from sql6.5 to sql 7.o
I have a table tblnetwork on which identity property
is defined on column networkid.
When I issue the following command new record is getting inserted into
tblnetwork and identity column is getting incremented properly.
But, I am not able to get the @@identity value
It is returned as NULL.
insert tblnetwork(formalname,networktype)
values ("name2",11897)
select @@identity
I need this value to insert into some other table.
Pls suggest me why @@identity is returning NULL

View 4 Replies View Related I have a SQL 2005 clustered server which is returning a Null value for @@servername. I find the server entry in sysservers. I have replication configured on this so i am not able to do a Sp_dropserver & sp_addserver as this acts as a publisher.

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?
Hi,
I need to create a conditional expresssion where if a null value is found, then a letter "N" must be inserted.
I create this expression but didnt work: (COL1 == NULL) ? "N" : COL1
So, if COL1 is null, then N .. but if it is nt null tehn COL1 = COL1
I think i', having a problem expressing the null.
Any idea for this?
Thanks!
I am trying to insert a record to based on the source below, however the GUID of GiftOcc_ID is being returned as zero's so the first record can be added but as it is defined as the primary Key and uniqueidentifier the next record fails with a duplicate entry.

I've a package that has a excel source. But i'm having a strange problem with it. One of the columns in the source file have a lot of null values but not all of them. But when i run the package a put a data viewer right after the source and i can see that it's showing that the few fields that should have values are also null. I've tried a lot of things but they didn't work. I need some help and fast if possible.

Hi there ;
This Problem is goin to make me crazy!
I've got a table with couple of fields, 2 of them are DateTime, in Sql Express 05 .
I used asp.net 2.0 to insert datetime values, directly, using sth like DateTime.Now.ToString() .
i use 2 selects as follows :
1)select * from X where Date1='8/9/2006 11:17:41 AM'
2)select * from X where Date2='8/9/2006 11:17:41 AM'
#1 is OK, but the second one returns a row with all columns set to NULL .
(X is the name of the table)
Thanks in advance

resultSetSQLServer = statementSQLServer.getResultSet();
System.out.println("b = " + b);
System.out.println("Are there any rows ?? " + resultSetSQLServer.next());
This code is returning null resultset.
But when I fire the same query directly into MS SQL, it is returning the corresponding rows.
I dont know where i'm going wrong. But just to make things more clearer, here's my connectivity code :

We currently have an SQL db running on a web server.One of these fields is a large(ish) amount of text data – up to 400characters – and has been cast variously as varchar, nchar and texttype to overcome a problem. The problem appears to be in retrievingthe data via ASP. I understand that ASP can handle string data of thissize so I am okay there.When the records are retrieved from the db, the data string length =0.I know the data is there because I have written a Delphi data managerwhich interrogates the db and shows all records and their contents.So if ASP can handle strings this size and the data is there, why do Iget a data length of zero bytes returned when I interrogate the recordset?Whichever way I cast this field I get the same result.I know the code is sound as it works locally through a MS SQL serveron my PS.Anyone have this problem or know what's causing it? I have logged asupport call with my hosting company, but they haven't replied as yetand I am stuck on an urgent project.Any suggestions?CheersGrant
View 1 Replies View RelatedHi,
I'm running into an issue where if a report retrieves 0 records, I run into an error. My report has 2 queries-- the main query to retrieve Account information and the other to return Contact information based on the contact id(s) returned by the Account query. The reason needing two separate queries is that the contact and account tables are on different databases.
Now here is my account query: select contact_id, username, password from account.
My contact query looks like this: select name, address, .... from contact where contact_id = @contact_id.
In my report parameters, I define contact_id like this:
*******************************************
name = contact_id
data type = integer
prompt = [blanked out]
hidden = checked
internal = checked
multi-value = unchecked
allow null value = checked
allow blank value = unchecked
available values:
from query: dataset = account
value field = contact_id
label field = contact_id
default values:
from query: dataset = account
value field = contact_id
**********************************************
Now, when I run my report and knowing there are no records, I get the following error: "The 'contact_id' parameter is missing a value". Any ideas on how to solve this issue? Thanks.

Hi,
I would like to know how I can indicate a NULL value in a report expression in SSRS / Report Designer.
I am trying to code :
IIF(Value_A = 0, <NULL>, Value_A)
It may look weird but I am trying to return NULL values when Value_A is 0 (zero), in the sample scenario above.
I have tried using the keyword "NULL", but it is highlighted as a syntax error, and suggested to use System.DBNull. I tried it and then it says that components of the System collection cannot be used in an expression, so I am left drawing blanks.
Thanks.

Kenny
Hi everyone!
I'm using a conditional split to discriminate modified records. My expression looks like this:
col1_source != col1_dest || col2_source != col2_des.....and so on. I use OLE DB Command afterward to update modified records.
It all works fine if no columns evaluate to null. If any (source or dest.) evaluates to null, component fails.
Any tips how to solve a problem?
It has to work like this:
If colX_source is null and colX_dest is not null --> Update
If colX_source is not null and colX_dest is null --> Update
If both colX_source and colX_dest are null --> No update
p.s. i apologize if a similar thread exists, I haven't found something of use to me.
