Can anyone show me or tell if the following is possible.
I have a SQL query as shown below:
SQL = "SELECT revenue_forecast.oct AS 'revenue' ...........
What I need to do is dynamically set the column in this SQL query. So i need to be able to place a variable in the part after the revenue_forecast "." .
Can someone show me how to do this?
It depends on your data source, but most data sources do not allow you to parameterize column names. You have a couple of choices. One is to concatenate the name into the string as in...

I come from a Microsoft SQL Server environment, so I am used to being able
to create dynamic SQL statements within a stored procedure with the EXEC
command. It appears that Sybase's equivalent command only recognizes
othere stored procedures. Does anyone know of a way to do this in Sybase?
ASE 12.0 supports dynamic execution of strings, see "execute" in Ref Manual.
In versions ASE 11.5 and higher, you can also use the sp_remotesql against the
"local" server, for much the same effect, although there are more limits using
this than the "execute imm...Dynamic SQL and mixing T-SQL/Watcom
SQL Anywhere version 5.5.01
I believe that Watcom SQL is my only option for dynamic SQL execution
(i.e. resolving object names at run time) in a procedure using EXECUTE
However we are likely to want to upgrade to SYBASE and would like to use
(the inferior?) T-SQL and its data types for portability. I am
currently calling a Watcom proc (using EXECUTE IMMEDIATE) from a T-SQL
procedure. Seems to work fine but this seems philosophically wrong and
I suspect will lead to problems. True?

I am using code that I found on the net to take a datatable, drop it into a datagrid, and then export the whole thing as an excel spreadsheet.
So far for the small numberes I have tried it works. Currently I have an application where the number of columns ranges between 40 and 70.
The problem that I have is I want the first row to have names which are meaningful to the user, but I don't want to rename my datatable columns, only the datagrid columns. Right now the Excel column names are the same as the datatable names. Those names are meaningful to me (the programmer) but meaningless to...SQL: Column names, can ONLY get "name" instead of "table.name"
When iterating through column names returned from a query, I need to get "table.name" rather than just "name"
Check it out:
If I have an SQL statement "SELECT table1.ID, table2.ID FROM table1, table2;"
And table1 has a column name 'ID'
and table2 has a column name 'ID' aswell,
and i run the query, the dataset will contain column names 'ID' and 'ID'
instead of 'table1.ID' and 'table2.ID'
It is extremely important that I can differenciate between the 2 fields, and know where each of them come from.

Hi, I have a problem retrieving the data with a DataReader from a stored proc that performs a join of two table with the same column's names but different data.
Let me explain with an example:
I have two tables:
Table1: Id, Name
Table2: Id, Name, IdTable1
The sproc is something like this:
CREATE PROCEDURE [dbo].[SearchByName]
FROM dbo.Table1, dbo.Table2
WHERE Table1.Id = Table2.IdTable1
AND Table1.Name LIKE '%' + @Name + '%'
And my c# code is something like this:

I am reading an article on stored procedures that create other stored procedures. It is discussing dynamic T-SQL used with EXECUTE to generate a stored proc. Then there is this warning (excerped below).
I don't quite understand how dynamic T-SQL would be used to cause a SQL injection attack. I am -not- looking for direction to create an attack; rather what exactly should I avoid doing? In the example below, how is dynamic T-SQL different from any other proc where variables are introduced.
Thanks in advance,

from the DWSyntax utility:
