DataSource Controls :: Stored Procedure Does Not Indicate Table Returned In Dataset?
Apr 23, 2010This may not be the correct place to put this as it is both a stored procedure AND Visual Studio 2008 problem.
I have the following stored procedure:
[Code]....
I have been mokeying around with it because of what is happening. I have a dataset, call it dataset1. I drag this stored procedure onto the dataset. I EXPECT a datatable to appear, instead the data set adds this store procedure to the queries table adapter and sets the exec mode to 'NonQuery' which unless I am very mistaken, means "don't expect a dataset back from this' when in fact you DO expect a dataset back from this.
The SQL server is a Windows 2000 Server running SQL 2000. It has never caused us a moments grief since we set it up oh-so-many years ago.
If I connect to a different database and drag a query into the same dataset I get a datatable as I expect. I cannot see where / how this procedure could be wrong. The query when executed returns exactly the data I expect, in the format I expect (looks like a table, acts like a table in the Query analyzer).
DataSource Controls :: UDF Or Procedure To Get Records For Transposed Numbers?
Mar 8, 2010I am looking for a function or procedure in sql server which assists me in figuring out the records which is having Transposed numbers. E.g one record is having invoice number as 1234 and another record is having invoice number as 2134(this is the definition for transposed records for me). My another problem is that the length of invoice number is not known. It can be from 1 character to 15 characters or more than that.

Mar 14, 2010 I have a standard gridview, with the standard paging and sorting interface enabled.The application holds appointments for three organisational units, with a maximum of 3000 appointment records being returned across all three units. The appointment records are quite small.
The choice I am faced with is to:
1. Have an Org Unit dropdown which returns to the datasource on change of selection and at inital databind, and returns appointment records for one org unit at a time i.e. approx 1000 records.
2. Have the objectdatasource return all 3000 appointment records for all org units at initial databind, and filter the objectdatasource by org unit on change of selection, thereby saving a trip to the datasource.
I guess the question boils down to identifying the point at which querying the datasource by org unit is more efficient than filtering the records returned by org unit.
Is 3000 records a lot for a gridview to be paging and sorting etc.

Set Sessions To Resultset Returned From Store Procedure?
May 17, 2010I have a procedure that im going to be calling on my page load, i will pass an id to it and it will return up to 6 records. I need to set a session for each record returned.
Can i do that within my page_load event to pass the value, and set the sessions?
