我有这个查询：
$sql = "SELECT CPACK, ('[' || CPACK || '][' || REPLACE(UPPER(DESC_PACK),UPPER(' ".substr(str_replace($battlezone," ",""),0,-1)."'),'') || ']') CPACKITEM
FROM p_product_indihome_valid
where (1=1) and cpack in (select cpack from p_paket where JENIS = 'A' and valid = '1' and paket like '%~".$paket."~%' and
id_rule in (select id_rule from p_paket_rule where (";
for($i=0;$i<count($param);$i++){
$sql2 .= " or (MTARGET = '".$paramName[$i]."' and REGEXP_LIKE (REPLACE(mvalue,'&','dan'),'~".str_replace('&','dan',$param[$i])."~|0'))";
}
$sql .= ltrim($sql2,' or');
$sql .= ") group by id_rule having count(mtarget) = 3)) group by CPACK,DESC_PACK ORDER BY DESC_PACK";
$stid = oci_parse($this->_conn, $sql);
$r = oci_execute($stid);
print_r($sql);
它显示：
SELECT CPACK, ('[' || CPACK || '][' || REPLACE(UPPER(DESC_PACK),UPPER(' '),'') || ']') CPACKITEM
FROM p_product_indihome_valid
where (1=1) and cpack in (select cpack from p_paket where JENIS = 'A' and valid = '1' and paket like '%~1~%' and
id_rule in (select id_rule from p_paket_rule where ((MTARGET = 'SUBLAYANAN' and REGEXP_LIKE (REPLACE(mvalue,'&','dan'),'~DCS - UCS II~|0')) or (MTARGET = 'LAYANAN' and REGEXP_LIKE (REPLACE(mvalue,'&','dan'),'~DCS~|0')) or (MTARGET = 'SOCIO' and REGEXP_LIKE (REPLACE(mvalue,'&','dan'),'~Lain-lain~|0'))) group by id_rule having count(mtarget) = 3)) group by CPACK,DESC_PACK
ORDER BY DESC_PACK;
我在SQL Developer中运行了查询，它显示了以下结果：
cpack | citem
USEE84 [USEE84][ADDITIONALSETUPBOXUSEETV]
C15062 [C15062][CS-INDIHOMEJOINPROMOVISACREDITCARDINTERNET]
C15061 [C15061][CS-INDIHOMEJOINPROMOVISACREDITCARDPHONE]
VOICE [VOICE][FEATUREVOICE]
但是当我用print_r($stid);显示查询结果时，它显示的是空值。我不知道错误在哪里。
您的代码当前没有获取结果集。
以下是如何使用oci_fetch_array获取结果集并获得您想要的结果——将其添加到代码的底部：
$results = [];
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
$results[] = $row;
}
print_r($results);
oci_fetch_array—以关联或数字数组的形式返回查询的下一行
用法：array oci_fetch_array（resource$statement[，int$mode]）
