我已經創建了一個PHP腳本，它將檢查連接的數據庫是否有一些預定義的表格，如果表格不存在，腳本將創建這些表格。檢查開關盒的執行是否成功
在這個腳本中，我用switch ... case來創建這個表格，這個表格沒有任何錯誤。
現在我想要做的是檢查switch ... case結束了沒有任何錯誤。如果沒有錯誤，那麼我想發射另外一組或者說sql聲明，這些聲明會創建一些每天要運行的任務。
這是我的表檢查和創造PHP部分，
<?php
//This is the array that contains all the table names
$tableNames = array(
'catdb', 'clientdb', 'qcerrors', 'searchterm', 'teams', 'tempdb', 'userlogin', 'userroles', 'usertimetrack'
);
//I'm using this for loop to loop through the array and create the tables
//if they doesn't exists.
for ($i = 0; $i < count($tableNames); $i++) {
$tableCheck = $dbConnect->query("SHOW TABLES LIKE '" . $tableNames[$i] . "'");
if ($tableCheck->rowCount() > 0) {
echo $tableNames[$i] . " .... Exists <br />";
} else {
$tblName = $tableNames[$i];

現在上面的代碼與運行出來後我想下面的語句SQL將創建任務運行任何錯誤。
<?php
$timeNow = date("Y-m-d H:i:s"); //To get the current time
//Set the event scheduler status from OFF to ON
$dbConnect->exec("SET GLOBAL event_scheduler = ON");
//Creates the daily task 1 to truncate searchterm table
$createTask1 = "CREATE DEFINER= '" . $dbUser . "'@`%` EVENT `searcTerm Table Clean` ON SCHEDULE EVERY 1 DAY STARTS '" . $timeNow . "' ON COMPLETION NOT PRESERVE ENABLE DO TRUNCATE TABLE searchterm";
$dbConnect->exec($createTask1);
//Creates the daily task 1 to truncate tempdb table
$createTask2 = "CREATE DEFINER= '" . $dbUser . "'@`%` EVENT `EmptyData` ON SCHEDULE EVERY 1 DAY STARTS '" . $timeNow . "' ON COMPLETION NOT PRESERVE ENABLE DO TRUNCATE TABLE tempdb";
$dbConnect->exec($createTask2);
?>
我沒有搜索谷歌和SO，但沒有看到一個答案，這就是爲什麼我決定問這個問題。我希望我已經向社區明確了我的問題，如果有的話，我們可以澄清一下做什麼以檢查switch ... case，並以任何錯誤結束。
MyISAM？真？ – GordonM
那你能告訴我一個更好的嗎，請使用'MySQL'中的默認引擎。 – Sand
InnoDB是MySQL的默認設置，並且已有多年。你正在使用相對較新版本的MySQL，對吧？此外，拉丁語1可能會在未來困擾你，爲什麼不使用UFT8MB4？ – GordonM
