esProc can solve this problem easily. It is just like Excel+SQL, a free tool, see: A Query Language Over-perform SQL
[^].
code as below:
A1: =sqlsvr.query("select Name,Dates,[Outstanding Values] from test_table order by Name,Dates")
A2: =A1.derive(:Difference)
A3: =A2.group(Name)
A4: =A3.(~.run(Difference='Outstanding Values'-'Outstanding Values'[-1]))
I can't post a image file,so here are some explains:
A1 cell:query some data from database.
A2 cell:add a column to A1, named "Difference", just no data.
A3 cell:group the data by field "Name" in A2 cell. Here are 3 groups,
A4 cell:within every group(i.e. "~"), modify the field "Difference". The algorithm is: "this row" subtract "last row"(i.e. 'Outstanding Values'[-1])
I think esProc is more simple for mass data computation
BTW. how to post a image file?

Hi
How to write a where condition in the OPENQUERY to get data from ms access using linked server.
select * from openquery(AccessDB,'select * from TblEmp where EmpPK=1'). This query show the following error message
" OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "AccessDB" returned message "No value given for one or more required parameters.".
Msg 7320, Level 16, State 2, Line 1
Cannot execute the query "select * from TblEmp where EmpPK=1" against OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "AccessDB". "
With out where condition its working fine
Thankyou

Had you added server to sql server
|
|
|
|

Access gives you the error message "No value given for one or more required parameters." when you specify a non-existent column name. It assumes that it is a query parameter and complains that its value has not been supplied.
Check if the TblEmp table in the Access database contains an EmpPK column. Most probably, it does not. You might have misspelled the column name.

How to check whether a database has a table out of that database
|
|
|
|
|
This might help you:
select count(table_name) from information_schema.tables
However, some databases might not support it.

Why, will it also hold tables out of "other" databases?
You can check if a table exists by quering sys.tables in Sql Server. Other database-servers will have similar options.

It depends which database you are using.
If you are using MSAccess , then you can write the code in any language and using TABLE collection you can count and note the tables name
If you are using SQL SERVER , then here is querey "SELECT * FROM Sys.Tables"
If you are using MySQL , then here is query
SHOW [FULL] TABLES [{FROM | IN} db_name]
[LIKE 'pattern' | WHERE expr]
|
|
|
|

Yet another way to get a list of tables in an ADO.net-supported database:
System.Data.Common.DbConnection con =
this.command.Connection as System.Data.Common.DbConnection ;
if ( con != null )
{
System.Data.DataTable temp = con.GetSchema
(
"TABLES"
) ;
temp.DefaultView.RowFilter = "TABLE_TYPE='TABLE' OR TABLE_TYPE='BASE TABLE'" ;
temp.DefaultView.Sort = "TABLE_NAME" ;

What are you going to do if it doesn't?
|
|
|
|

I want to create a table in that database similar to the table in another database.
|
|
|
|
|
try with this..
If Object_ID('dbo.MyTable') IS NOT NULL
PRINT 'MyTable Exists'
Else
PRINT 'MyTable Not Exists'

Hey,
What database are you talking about?
MySQL,
Microsoft SQL Server
ORACLE
....
|
|
|
|
|
|
Once Again, What version of SQL Server?
SQL Server 2000
SQL Server 2003
or What?
|
|
|
|
|
You can use this code to check if a table exists.
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[MyTable]') AND type in (N'U'))
PRINT 'MyTable exists.'
ELSE
PRINT 'MyTable does not exist.'
|
|
|
|
|
try with this..
If Object_ID('dbo.MyTable') IS NOT NULL
PRINT 'MyTable Exists'
Else
PRINT 'MyTable Not Exists'

If there is a view or stored procedure with the same name, this script will fail.

Just a guess, but shouldn't it be
CREATE OR REPLACE PROCEDURE sp_add_event_log
(
...
...
)
AS <<== I don't see this in your SQL
BEGIN
...

Then how can i say CREATE it if it does not exist and REACE if exist?
|
|
|
|

I think just the "AS" keyword is missing from your original code. The use of CREATE OR REPLACE is valid at anytime.
