我是php的新手,无法从存储过程中获取结果集,如果可能的话,我希望以过程格式提供答案。
存储过程如下:
DROP PROCEDURE IF EXISTS getJobs;
DELIMITER $$
CREATE PROCEDURE getJobs(IN inputName VARCHAR(50))
BEGIN
SELECT JobNo FROM jobs WHERE PersonnelName= inputName;
END $$
DELIMITER ;
在MySQL Workbench中,此返回30539
我提出了以下php代码。
<?php
//imports the connection
require "conn.php";
$name = "chrisf";
$call = mysqli_prepare($conn, 'CALL getJobs(?)');
mysqli_stmt_bind_param($call, 's', $name);
mysqli_stmt_execute($call);
$result = mysqli_use_result($conn);
//debug to check the result
echo '<pre>'; print_r($result); echo '</pre>';
//loop the result set and echo
while ($row = mysqli_fetch_array($result)){
//the command I expect to output the result
echo "Entry" . $row[0] . "<br>";
//debug to check the result
echo "Entry" . $row . "<br>";
}
$conn->close();
?>
运行时,将提供以下输出:
mysqli_result Object
(
[current_field] => 0
[field_count] => 1
[lengths] =>
[num_rows] => 0
[type] => 1
)
Entry
EntryArray
由于如果我使用不返回任何结果的输入,则mysqli_result对象会消失,这似乎很接近,但实际上并不包含数据。
谢谢。
答案 0 :(得分:0)
我看起来不太优雅,但是我提出了以下内容,这些内容足以让我满意:
<?php
//imports the connection
require "conn.php";
//builds the MySQL stored procedure all
$name = "chrisf";
$input = "CALL getEngineersJob('".$name."')";
//executes the store procedure
$result = mysqli_query($conn,$input) or die("Query fail: " . mysqli_error());
//loop through the output and echo
while ($row = mysqli_fetch_array($result)){
echo $row[0] . "<br>";
}
//free resources
mysqli_free_result($result);
$conn->close();
?>
