pg_result_status — Lee el estado del resultado
pg_result_status() devuelve el estado del resultado
result o el comando de ejecución de PostgreSQL
asociado al resultado.
resultAn PgSql\Result instance, returned by pg_query(), pg_query_params() or pg_execute()(among others).
mode
Puede ser PGSQL_STATUS_LONG para devolver un estado
numérico de result o
PGSQL_STATUS_STRING para devolver la etiqueta del
comando de result. Si el argumento no se
especifica, PGSQL_STATUS_LONG es el valor por omisión.
Los valores de retorno posibles son PGSQL_EMPTY_QUERY,
PGSQL_COMMAND_OK, PGSQL_TUPLES_OK,
PGSQL_TUPLES_CHUNK, PGSQL_COPY_OUT,
PGSQL_COPY_IN, PGSQL_BAD_RESPONSE,
PGSQL_NONFATAL_ERROR y PGSQL_FATAL_ERROR
si PGSQL_STATUS_LONG se
especifica. De lo contrario, se devuelve un string que contiene la etiqueta del comando PostgreSQL.

The result parameter expects an PgSql\Result
instance now; previously, a recurso was expected.

Ejemplo #1 Ejemplo con pg_result_status()
<?php
// Conexión a la base de datos
$conn = pg_pconnect("dbname=publisher");
// Ejecución de COPY
$result = pg_query($conn, "COPY autores FROM STDIN;");
// Obtención del estado
$status = pg_result_status($result);
// Determinación del estado
if ($status == PGSQL_COPY_IN)
echo "La copia se ha realizado.";
else
echo "La copia ha fallado.";
?>El resultado del ejemplo sería:
La copia se ha realizado.
0 = PGSQL_EMPTY_QUERY
1 = PGSQL_COMMAND_OK
2 = PGSQL_TUPLES_OK
3 = PGSQL_COPY_TO
4 = PGSQL_COPY_FROM
5 = PGSQL_BAD_RESPONSE
6 = PGSQL_NONFATAL_ERROR
7 = PGSQL_FATAL_ERRORThis function is useful it may not return a full non fatal error but you want to see if the query completes anyway.
example
<?PHP
//connect to pg database
// create PGSQL
$PGSTAT = pg_result_status($PGSQL);//defaults to long
//And run it through a check for example
if(($PGSTAT == 1) || ($PGSTAT == 2)){
// for query results;
}else if(($PGSTAT == 3) || ($PGSTAT == 4)){
// for copy results;
}
if(($PGSTAT != 0) && ($PGSTAT != 5) && ($PGSTAT != 6) && ($PGSTAT != 7)){
// your code;
}else{
// $ERRORS codes;
}
// This is worked the best for me so far I tried using
// The command tag and I seem to still get an numeric result
//example
//$PGSTAT = pg_result_status($PGSQL, PGSQL_COMMAND_OK);
// got something like tuples ok so I recommend just use default long
?>
or use what ever condition check you feel fitThe postgres docs say that PHP should never be able to return PGRES_NONFATAL_ERROR
"A result of status PGRES_NONFATAL_ERROR will never be returned directly by PQexec or other query execution functions" http://www.postgresql.org/docs/current/static/libpq-exec.html
Therefore you cannot use this function to check if this query produced a notice.
