Hi I have an urgent problem
I want to insert values into a table using the C syscalls provided by the libpq library, but i find that i can not insert into the table when i use variables instead of values...like so:
int a,b,c,d;
using the C function
res=PQexecute(Conn,"INSERT into table values(a,b,c,d));....
executing above statement with plain integers does fine and inserts them into table..
Is there some special way to insert variables rather than plain values? do i have to build functions (in sql) or somehting?help!
Thanx

So, you are an artist. Isn't it? :)
Your query is actually a string.
This is your string: INSERT into table values(a,b,c,d)
You must change your string to actually use values of tha a, b...
You can make this string with sprintf
sprintf(string, "INSERT into table values(%d,%d,%d,%d)", a, b, c, d);
Then you launch:
res=PQexecute(Conn, string);
Why don't you use PHP? Is easier.
Have a nice day

You can also use PGexecParams() (see the libpq documentation). It can be a little more cumbersome to use, though.
Best Wishes,
