oci_num_rows

(PHP 5, PECL OCI8 >= 1.1.0)

oci_num_rows — 文の実行で作用された行数を取得する

説明

int oci_num_rows ( resource $statement )

文の実行で作用された行数を取得します。

パラメータ

statement: 有効な OCI ステートメント ID。

返り値

作用された行の数を表す整数値、あるいはエラー時に FALSE を返します。

例

例1 oci_num_rows() の例


<?php
$conn = oci_connect("scott", "tiger");

$stmt = oci_parse($conn, "create table emp2 as select * from emp");
oci_execute($stmt);
echo oci_num_rows($stmt) . " rows inserted.<br />";
oci_free_statement($stmt);

$stmt = oci_parse($conn, "delete from emp2");
oci_execute($stmt, OCI_DEFAULT);
echo oci_num_rows($stmt) . " rows deleted.<br />";
oci_commit($conn);
oci_free_statement($stmt);

$stmt = oci_parse($conn, "drop table emp2");
oci_execute($stmt);
oci_free_statement($stmt);

oci_close($conn);
?>

注意

注意:
この関数は、select が返す行の数は 返しません ! SELECT 文の場合、この関数は oci_fetch*() 関数によってバッファに取得された行数を返します。

注意:
PHP バージョン 5.0.0 以前では、代わりに ocirowcount() を使用しなければなりません。まだこの名前を使用することができ、下位互換性のため oci_num_rows() への別名として残されていますが、推奨されません。

If you want to return te number of rows without fetching all data it might by more efficient to use this code (correct me if I'm wrong):



$sql_query = 'SELECT COUNT(*) AS NUMBER_OF_ROWS FROM (' . $your_query . ')';



$stmt= oci_parse($conn, $sql_query);



oci_define_by_name($stmt, 'NUMBER_OF_ROWS', $number_of_rows);



oci_execute($stmt);



oci_fetch($stmt);



echo $number_of_rows;

hello, 


here'is an example  who works:





$connexion = ("name_bd","pass_db");  //set up connexion on database


$query="select * from order ";   // query for the test 


$parse = ociparse($connexion,$query);   // parse query


ociexecute($pase);   // execute the query on server (on temporary memory)


ocifetchstatement($pase,$tab_result);  // the result will be fetched in the table $tab_result


echo ocirowcount($parse);  // show the numbers of result





/**** and if you want to posting the results of query ***/


$count = count($tab_result);


for($i=0;$i<=$count;$i++)


{


     echo $tab_result[$i]."<br>";


}





you can also do it with the function ociresult():





while(ocifetch($parse))


{


    echo ociresult($parse,"[capital letter of the name of feild that you want to show on naviator]");


}





Attention : all of name of tables on oracle database are in capital letter when you use an other application for connect to it.


example : 





to select the field no_client on table client, on your script of posting, you should write :





echo ociresult($parse,"NO_CLIENT");





not :





echo ociresult($parse,"no_client");





//end





Enjoy

It appears the easiest workaround if you want to get numrows without moving to the end of the result set is to use:





numrows = OCIFetchStatement(...);


OCIExecute(...);





So that the execute re-executes the query. It's horribly inefficient to query twice, but it works.

this function can be used with select statement, and also return affected number of rows. 


But remember this, use this after fetch statement.
