Hi
I have created a Trigger Statement and assigned to CommandText property of
sqlCommand.While Try to Execute using
command.ExecuteNonQuery() it throws an exception like
{"Incorrect syntax near the keyword 'TRIGGER'."}
Created Trigger Statement:
CREATE TRIGGER SampleTrigger
ON dbo.sample
AFTER INSERT
AS begin
SET NOCOUNT ON
DECLARE @Name AS nvarchar(50)
SELECT @Name= i.Name from inserted i
DECLARE @Address AS nvarchar(50)
SELECT @Address= i.Address from inserted i
insert into triggertest(statusID,FieldName,FieldValue) values( 25,'Name',@Name)
insert into triggertest(statusID,FieldName,FieldValue) values( 25,'Address',@Address)
end
Can anyone help me?
Thanks in advance

Since you don't show the way you build up the string, my guess is that the string sent to the SqlCommand is not exactly the one shown.
For example:
string sql = "CREATE TRIGGER SampleTrigger" +
"ON dbo.sample";
will actually result in a string that reads:
CREATE TRIGGER SampleTriggerON dbo.sample

i dont knoe how can use it.
please tell me what string i pass in GetDefaultConnect() for execute my application properly for each computer.
Thanks in advance.

Hi All,
I have the following defined in a class that I'm using to access and export the contents of an SQL Compact database. After having read around some I was under the impression that the following code would work, but its failing to actually LOAD any data from the database. Any help would be great.
to create my typed dataset:
SSdbDataSet ds = new SSdbDataSet();
The method to load the entire database from the .sdf file is:
public void ExportDatabaseXML()
{
ds.Clear();
ds.localSamples.Load(GetLocalSamplesReader());
ds.WriteXml("SStest.xml", XmlWriteMode.WriteSchema);
}
And there is this 'utility' method to create the reader:
private IDataReader GetLocalSamplesReader()
{
return ds.localSamples.CreateDataReader();
}
I'm a bit stuck now as I was under the impression that the Load() method pulled all the data from the underlying datatable.
Any pointers would be great.

Hey Guys,
Lets say we have a table T1 that have a numeric field F:
Table T1 (int ID, int F)
I need to update this table and set F to the MAX +1 to insure uniqueness:
UPDATE T1
SET F = (SELECT ISNULL(MAX(F),0) + 1)
WHERE ID IN(1,2)
The thing is I end up with both IDs 1 and 2 having the same value for F. I remember doing but what do I have to change so that Max is calucated for row in T1 so that if my initial table is like:
ID F
1 1
2 2
Running the update query will get the following result
ID F
1 3
2 4
Thanks.

UPDATE T1<br />
SET F = (SELECT top 1 ISNULL(MAX(t2.F),0) + 2 from T1 as t2 where t2.id=T1.ID)<br />
WHERE ID IN(1,2)
I Love T-SQL

Any easy way to do that is:
DECLARE @I INT
SELECT @I = MAX(F) FROM T1
UPDATE T1
SET @I = F = @I + 1
Change T1 and F for your actual names.

I have a table similar to the following :-
Id, BigInt, IsIdentity
Name, VarChar(50)
ParentId, BigInt, Allows Nulls
Therefore I could have data as follows
Id Name ParentId
-- ---- --------
1 Fred Null
2 Fred 1
3 Fred 1
4 Fred 2
5 Fred 4
Therefore data is structured as follows :-
1, Fred
..2, Fred
....4, Fred
......5, Fred
..3, Fred
What I need to do, (and this is where my weak T-SQL lets me down) is when the Name is change for row 1, an update cascades through the table and updates and related row i.e. where ParentId = Id of row updated.
My thoughts are to use an trigger on Update, but I need some help with the code.
Also, if I understand the update tigger correctly, and the option is enabled at Database level, the rows being updated by the trigger will cause the trigger to fire again, thus the update with cascade down the tree.
Any assistance is much appreicated.

Hi, try something like this:
CREATE TRIGGER [Table1_Update] ON [dbo].[Table1]
FOR UPDATE
AS
IF EXISTS(SELECT * FROM inserted)
UPDATE Table1 SET [Name] = I.[Name] FROM Table1 T INNER JOIN inserted I ON T.ParentID = I.ID
You're right in that the trigger recurse option needs to be enabled (disabled by default), but be aware that you're limited to 32 levels in the recursion stack (sql server 2000 - don't know limit in SQL2005), so you're tree must be limited to max 32 levels

I have a nasty feeling you are setting yourself up for a disaster. I don't understand your requirement but some of your statements are suspect.
the field name should never be used in a relationship. It should be stored once and the ID used to define your heirachy. You need 2 tables for this operation.
Name Table
ID int, Name varchar(?)
Link Table
ID int, ParentID int
Id ParentId
-- --------
1 Null
2 1
3 1
4 2
5 4
and join out to the name table (twice for ID and ParentID).

I understand your concerns and thanks for raising them. I did not go too deeply into what I need to achieve because I did not think it relevent to the problem (i.e. my lack of knowledge) at the time.
Just to make things clear, the problem I have is will a database created and maintained by a third-party product, namely Sage SalesLogix CRM package. I have a requirement where the principle contact at a parent account is also the principle contact at each associated child account, but SalesLogix does not cater for this requirement as standard. Therefore some coding has been done on SalexLogix that when a child account is associated with the parent account, then principle contact of the parent is copied to child. So far so good.
Now the problem is, that when the details of the contact is changed, it is only for the that one record. This is where the trigger comes into play. What I want to do is when the details of a contact is changed, all duplicate(ish) records are updated to reflect the change, hence my example showing a column called 'Name' with the same value.
Thanks again for you concern.
Best regards
Steve Jowett

Steven, this should be held us as a classic DB design error 101 - typical of Sage.
Are you attempting this in SageLogix (not), if so then my sympathy.
I would naturally [avoid] triggers because I hate them . If you can inject an Exec into the save process I would use a stored proc to synch the data based on the ParentID and new contact name. I presume the user can update the contact from either the child or the parent.
Good luck

I am using following query ..
select siid as Sid,biid as Bid,(select iname from Ol_items where iid=siid) as SIName,(select iname from Ol_items where iid=biid) as BIName from Ol_Wishlist

This should do it (around each of the subqueries):
COALESCE((select iname ...), 'NO') as ...
Look up the COALESCE function in the documentation for details.

Its working fine.....Thanks alot...

Personally I would use a CASE for that, although as the other poster suggested a COALESCE would work.

yes, but coalesce is standard, so I prefer it to isnull which is not.

You can use coalesce function:
select siid as Sid,biid as Bid,coalesce ((select iname from Ol_items where iid=siid),'NO') as SIName,(select iname from Ol_items where iid=biid) as BIName from Ol_Wishlist

Hey guys
ive got a table in my DB, employee... this table has a column "EndOfEmployment" which is DATETIME and obviously nullable
yesterday while trying to write a query to count the number of "Active" employees i came across a strange issue... the query is as follows
SELECT count(Emp_EmployeeNumber)
FROM Employee
WHERE Emp_EmploymentStatus = 'A' OR (Emp_EmploymentStatus = 'T' AND (Emp_EndOfEmployment = NULL OR Emp_EndOfEmployment < @todaysDate))
i noticed that when the EndOfEmployment field does not get data in the insert statement, it DOES NOT get a value of NULL... so i tried giving it a value of NULL in the insert statement and that still didnt work.
then i tried Emp_EndOfEmployment = '' instead of Emp_EndOfEmployment = NULL in the WHERE clause but still no luck
Does anyone have any ideas?
Thanx
