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!
