Andy:

 

If you are programming in, say C++, it is fairly straightforward to write a
function with this capability.

Have the function take as parameters the tablename, along with vector of
pointers to a user-defined class Parameter.

If each Parameter contains type information, along with the value,
formatting & executing the query string is a snap.

 

 

Best,

 

Paul

Subject: [freetds] prepared statements in db-lib

 

I have been playing with db-lib, and find it to be a very nice

interface. But there is one thing that I seem to be missing, and can't

figure out -- does it not have any way to do a "prepared statement" --

IOW, a statement with parameters that are filled in before execution --

other than as an actual stored procedure?

 

Here's what I want to be able to do, in a mixture of sql and

pseudo-code:

 

sql_statement: INSERT INTO test_tbl VALUES ( ?, ?, ? );

set_param(1, 52)

set_param(2, 'Testing')

set_param(3, 123.456)

execute prepared statement

 

If db-lib cannot do this, can ct-lib? Or do I have to go down to the

libtds layer?

 

Many thanks ...
