pg_result_status — Obtém o status do resultado da consulta
pg_result_status() retorna o status da instância PgSql\Result ou a tag de conclusão do comando PostgreSQL associada ao resultado.
resultUma instância de PgSql\Result, retornada por pg_query(), pg_query_params() ou pg_execute() (entre outras).
mode
Pode ser a constante PGSQL_STATUS_LONG para retornar o status numérico
de result ou a constante PGSQL_STATUS_STRING
para retornar a etiqueta de comando de result.
Se não for especificado, PGSQL_STATUS_LONG é o padrão.
Os possíveis valores de retorno são PGSQL_EMPTY_QUERY,
PGSQL_COMMAND_OK, PGSQL_TUPLES_OK, PGSQL_TUPLES_CHUNK, PGSQL_COPY_OUT,
PGSQL_COPY_IN, PGSQL_BAD_RESPONSE, PGSQL_NONFATAL_ERROR e
PGSQL_FATAL_ERROR se PGSQL_STATUS_LONG for
especificado. Caso contrário, uma string contendo a etiqueta de comando do PostgreSQL será retornada.

O parâmetro result agora espera uma instância de PgSql\Result;
anteriormente, um resource era esperado.

Exemplo #1 Exemplo de pg_result_status()
<?php
// Conecta ao banco de dados
$conn = pg_pconnect("dbname=publisher");
// Executa um COPY
$result = pg_query($conn, "COPY authors FROM STDIN;");
// Obtém o status do resultado
$status = pg_result_status($result);
// Determina o status
if ($status == PGSQL_COPY_IN)
echo "A cópia começou.";
else
echo "Falha na cópia.";
?>O exemplo acima produzirá:
A cópia começou.
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 fitIf on "accident" your program passes pg_result_status a variable that is NOT a actual pg resource, it will return an empty string.
(This is important to know if you want to make sure a pg resource is "good" before attempting some operation on it).The 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.
