[英]Php mysqli works for sql but not working for stored procedure
$table = "alabama";
$sql = "SELECT distinct zip FROM {$table} where zip is not null order by zip;";
$sql .= "SELECT distinct city FROM {$table} where city is not null order by city;";
$sql .= "SELECT distinct county FROM {$table} where county is not null order by county;";
$mysqli = new MySQLI('host','user','pass','db');
if ($mysqli->multi_query($sql)) {
do {
if ($result = $mysqli->store_result()) {
while ($row = $result->fetch_row()) {
echo($row[0]);
}
$result->close();
}
if ($mysqli->more_results()) {
echo ("next result");
}
} while ($mysqli->next_result());
}
$mysqli->close();
上面的工作原理很好,現在的問題是在存儲過程中使用了相同的sql(經過測試的存儲過程在命令行中運行良好)。 如果我將sql字符串替換為
$sql = "CALL {$table}_zip();";
$sql .= "CALL {$table}_city();";
$sql .= "CALL {$table}_county();";
則以上腳本不會給出結果。
我什至用單個存儲過程調用它都沒有給出結果的測試。
檢查在mysql數據庫中為procs_priv

我已經敲了一個簡單但功能豐富的示例(不包括參照完整性),您可能會發現...
完整的腳本可以在這里找到: http : //pastie.org/1303023
調用單個存儲過程將返回多個結果集。 您當然可以只調用3個獨立的存儲過程。
<?php
$conn = new Mysqli("localhost", "foo_dbo", "pass", "foo_db");
$result = $conn->query(sprintf("call list_state_counties_cities(%d)", 1));
$row = $result->fetch_assoc();
echo $row["name"], "<br/>";
$conn->next_result();
$result = $conn->use_result();
while($row = $result->fetch_assoc()) echo $row["county_id"], "<br/>";
$conn->next_result();
$result = $conn->use_result();
while($row = $result->fetch_assoc()) echo $row["city_id"], "<br/>";
$result->close();
$conn->close();
