Hi, I queried this a couple of days ago and got an excellent response, The software works, the query is sent, but the printed order the same order in which the data was entered. So either my query is being chopped at the order by statement, or I'm not printing it correctly. now, I wonder if anyone more experienced at bot c and postgres can see what I am doing wrong here: (I'm a novice so bear with me:-)) C code: sprintf(query, "select * from %s order by %s", table, PQfname(result, 0)); fprintf(cgiOut, "<CENTER>%s</CENTER><BR>\n", query); res = PQexec(conn, query); if((!res) || (PGRES_TUPLES_OK != PQresultStatus(res))) { fprintf(cgiOut, "<BR><CENTER>Error Sending Query</CENTER><BR><CENTER>Detailed Report: %s</CENTER>\n", PQerrorMessage(conn)); PQfinish(conn); fprintf(cgiOut, "</BODY>\n"); fprintf(cgiOut, "</HTML>\n"); exit(1); } for (i = PQntuples(res)-1; i >= 0; i--) { for(y = 0; y < z; y++) { fprintf(cgiOut,"<TD>%s</TD>\n", PQgetvalue(result, i, y)); } fprintf(cgiOut, "<TR>\n"); } fprintf(stdout, "</TABLE>\n"); fprintf(cgiOut, "</CENTER>\n"); fprintf(cgiOut, "</BODY>\n"); fprintf(cgiOut, "</HTML>\n"); exit(0); } Debugging File: read_pg_options: syslog=2,verbose=2,query=4 debug info: User = root RemoteHost = localhost RemotePort = 0 DatabaseName = oilfield Verbose = 3 Noversion = f timings = f dates = Normal bufsize = 64 sortmem = 512 query echo = f InitPostgres StartTransactionCommand query: select * from companies ProcessQuery CommitTransactionCommand StartTransactionCommand query: select * from companies order by comp_name ProcessQuery CommitTransactionCommand proc_exit(0) [#0] shmem_exit(0) [#0] exit(0) Am I blind or, just plain tired from too many late nights? ;-) Ken kvp@ocol.com
