When i call the procedure below from a ecpg program i get
sql error too few arguments.. before and after executing the function..

ranjani.


CREATE FUNCTION insert_zone_man(varchar,varchar,int4,int4) RETURNS int4
AS '  DECLAREtmp RECORD;p_ip ALIAS FOR $1; c_ip ALIAS FOR $2;sts ALIAS FOR $3;zm_flg ALIAS FOR $4;  BEGIN       IF p_ip
ISNOT NULL THEN SELECT INTO tmp ip_address FROM Node WHERE node.ip_address = ''p_ip'';
 
        IF NOT FOUND THEN     INSERT INTO Node VALUES(c_ip,sts,zm_flg); END IF;
END IF;   RETURN 1; END;
' LANGUAGE 'plpgsql';

I am calling this function from test.pgc program as follows..

#include <stdio.h>

exec sql include sqlca;
exec sql whenever sqlerror sqlprint;

int
main ()
{
exec sql begin declare section;char command[500];
exec sql end declare section;    char msg[128];    FILE *dbgs;    int i,j;
    if((dbgs = fopen("log", "w")) != NULL)      ECPGdebug(1, dbgs);
    strcpy(msg, "connect");    exec sql connect to distributed;
    strcpy(msg, "calling function");    sprintf(command , "SELECT
insert_zone_man('10.0.0.1'::varchar,'10.0.0.112'::varchar,1::int,1::int)");
    exec sql execute immediate :command;

    strcpy(msg,"disconnect");    exec sql disconnect;
    if(dbgs != NULL)      fclose(dbgs);
    return(0);
}
