Shaun,

You need a bit of db-library education!
I'd suggest you look at:

http://sybooks.sybase.com/onlinebooks/group-cn/cng1250e/dblib

or SQL server books online.

Also a good place to start would be to look at some of the freetds
db-library unitttest programs:

<freetds>/src/dblib/unittests

many of these go through the basic dblibrary API calls to select data
into your program, 

t0002.c looks good.

Then lookup the various dblibrary API functions in SQL server BOL..

dbresults()
dbbind()
dbnextrow()


HTH,

Bill

Subject: Re: [freetds] Return the InsertID after an Insert?


This is proving abit harder than i thought! Im new enough to freetds and

so far i've only had to do basic querys and inserts which is easy
enough.

my problem now is i can get the value i want but dont know how to pass 
it into a variable, eg...

INSERT INTO Table(column1,column2,etc...) VALUES (etc..........) SELECT 
@@IDENTITY AS 'Identity'

when i run this query in tsql it returns the value i want under the 
column heading Identity.  So how do i get the value and pass it into a 
variable?

i use dbsqlexec to execute the query, i tried calling dbresults, dbbind,

and dbnextrow after as you would for a query but cant get the value 
stored in Identity.

any ideas?

Shaun.
