It cheats a bit - and so doesn't require knowledge of the oldest and latest dates.
As a worked example: If the @StartDate is blank and the @EndDate is "1 Mar 2007" then the where clause is equivalent to:
where DateEntered between DateEntered and '1 mar 2007' Pete's second answer (using the Coalesce function) is exactly the same. I tend to use "IsNull" because its easier to spell
Hope that helps.

Hi
For date filtering, try this:
From front-end, pass default value as Min: 01/01/1900 and Max: 01/01/9999 if date values are not entered or blank
In your select statement, add this statement
IsNull(DateCol,'01/01/1900') >= Convert(nvarchar(12),@FromDate,101) AND
IsNull(DateCol,'01/01/9999') <= Convert(nvarchar(12),@ToDate,101)
Change date format from '101' to anything based on the format (whether MM/dd/yyyy or dd/MM/yyyy) you are storing in the database.
IsNull function on the left side is required as if you are allowing NULL values for the date field.
That 's it.

I have a service (which I have written in C#) that I want to run on 2 different computers however they will both be accessing the same database.
Is there a way to tell when one computer is writing to the database so I can stop the other from writing to it at the same time to avoid contention issues?

It would help to know what kind of database... Access, SQL Server, ...

In that case, no, you don't have to worry about it. SQL Server maintains order on its own. Just keep in mind that the "last write" will win.

I've been trying to consolidate/reuse some business logic in a recent project and doing so would require me (within a MS-SQL 2000 stored procedure) to get a dataset from a stored procedure and aggregate some data. Is there a way to get a dataset from a stored procedure and put it in a temporary table? This is not an output variable, just the regular output dataset. I'm using Microsoft SQL 2000.
Help please!
USE PD9
DECLARE @RC int
DECLARE @datebegin varchar(10)
DECLARE @dateend varchar(10)
SET @datebegin = '01/01/2007'
SET @dateend = '01/15/2007'
--this is a dataset of our sales reps
DECLARE sales_cursor CURSOR
FOR
SELECT DISTINCT
[ABAN8]
FROM
[vF0101_RepDetails]
ORDER BY [ABAN8]
OPEN sales_cursor
DECLARE @an8 int
FETCH NEXT FROM sales_cursor INTO @an8
WHILE (@@FETCH_STATUS <> -1)
BEGIN
IF (@@FETCH_STATUS <> -2)
BEGIN
-- i'm looping through a dataset of our sales reps
-- now i need to get a dataset from the below sproc
-- loop through that dataset and put it in a temp table
-- the problem is getting the dataset from the next line - HOW??
-- EXEC @RC = [PD9].[dbo].[usp_rs_getSalesShipments] @an8, @datebegin, @dateend
-- print @RC
END
FETCH NEXT FROM sales_cursor INTO @an8
END
CLOSE sales_cursor
DEALLOCATE sales_cursor

You can use:
INSERT INTO #MyTempTable (col1, col2, col3, ..., coln)
EXEC MyStoredProc where the temporary table's column list matches the columns returned in the stored procedures resultset (and their data types).

Hi,

Thanks

From VS 2005 documentation:
DataAdapter.Update - Calls the respective INSERT, UPDATE, or DELETE statements for each inserted, updated, or deleted row in the specified DataSet from a DataTable named "Table."
|
|

|

Thanks for your reply. "DataAdapter.Update" is for updating a DataTable in DataSet. I want to know how to insert this updated data back to SQL.

Try this snippet and let me know if it worked for you.
SqlConnection c = new SqlConnection(@"Data Source=(local)\SQL2005;Initial Catalog=TEST_DB;Integrated Security=True");<br />
SqlDataAdapter da = new SqlDataAdapter("select * from customer where customer_id = 1", c);<br />
SqlCommandBuilder cb = new SqlCommandBuilder(da);<br />
DataTable dt = new DataTable();<br />
<br />
da.Fill(dt);<br />
dt.Rows[0]["NAME"] = dt.Rows[0]["NAME"].ToString() + "1";<br />
da.Update(dt);

Hi
I have problem in getting primary and foreign key for a given table.
For example in a Adventureworks Database, Production.ProductCostHistory table.
If i try to get the foreign key related table it is not returning any value.
But ProductID is is both primary and foreign key.
How to get the foreign key table for the given table.
sp_fkeys not working if it is a composite key.
exec sp_fkeys @PKTable_name='ProductCostHistory',@PKTable_Owner='Production'
Can any one help me please?........

If you have the correct rights you can select your table from sysobjects where [name] = 'yourtablename'
You can use the id from that table to look in sysindexes for your primary keys.
Then you can look in sysforeignkeys to see if you have some foreignkeys
Hope that helps.

can you give me any sample example for a column, it is both primary and foreign key please.

It is not that easy.
First if you look in the sysobjects table for your table name to get the id.
Next if you look in the sysobjects table for an xtype = 'PK' that is a primary key that has a parent_obj = the id you found above. This gives you your primary key
Next you look in the sysforeignkeys table using the parentid
joined back to sysobjects to try and find a foreignkey if it exists.
So if you have a customer table and a customertype table
Customer Table:
customerId
CustomertypeId
... other stuff
CustomerType Table:
customertypeId
... other stuff
Here's a query:
declare @id int
select @id = id from sysobjects where [name] = 'customertype'
select * from sysobjects where xtype = 'pk' and parent_obj = @id
select * from sysforeignkeys fk
join sysobjects so on fk.fkeyid = so.parent_obj and so.xtype = 'f'
where fk.rkeyid = @id
I don't know if that helps at all it is quite complicated.

Thanks a lot ben
I have done this by following way
Select Tab1.Column_name,(select Schema_name(uid) from sys.sysobjects where id=PK_table_id)+'.'+Tab2.PKtable_name as PKTable_name, Tab2.PKColumn_name, Tab1.Table_Schema+'.'+Tab2.FKTable_Name as FKTable_Name, Tab2.FKColumn_Name from (Select Column_Name, Data_Type, Table_Schema from Information_schema.columns where Table_Name='Product' and Table_Schema='Production') Tab1 left outer join (select PKColumn_Name=c1.name,PKTable_Name=Convert(Sysname,Object_Name(f.refereced_Object_id)),PKTable_ID=f.referenced_Object_id,FKTable_Name=o1.name,FKColumn_Name=c2.name from sys.all_objects o1, sys.all_objects o2, sys.all_columns c1, sys.all_column c2, sys.foreign_keys f inner join sys.foreign_key_column k on(k.constraint_object_id=f.object_id) inner join sys.indexes i on (f.referenced_object_id=i.object_id and f.key_index_id=i.index_id) where o1.object_id=f.parent_object_id and o1.object_id=object_id('production.product') and o2.object_id=f.parent_object_id and c1.object_id=f.referenced_object_id and c2.object_id=f.parent_object_id and c1.column_id=k.referenced_column_id and c2.column_id=k.parent_column_id) Tab2 on Tab1.Column_name=Tab2.FKColumn_name

Hi!
How can one get a list of all the tables in an Access database using a query? ...I'm interested in something similar in effect to the SHOW TABLES in MySql.
