php - 按创建时间排序数据库表

Question

嗨，我想列出数据库中的所有表并按时间排序，到目前为止，我该怎么做才能列出数据库中的所有表，但无法按时间排序；

$dbname = "album";

if (!mysql_connect("localhost", "root", "")) {
echo "Could not connect to mysql";
exit;
}

$sql = "SHOW TABLES FROM $dbname";
$result = mysql_query($sql);

if (!$result) {
echo "DB Error, could not list tables\n";
echo "MySQL Error: " . mysql_error();
exit;
}
$sorts = array();
while ($row = mysql_fetch_row($result)) {
echo "Table: {$row[0]}"."<br>";
}

mysql_free_result($result);

Answer 1

这可能会帮助您：

$sql = "
SELECT create_time, table_name
FROM information_schema.tables 
WHERE table_schema = '$dbname'
ORDER BY create_time
";

同时更改while循环的内部部分，如下所示：

while ($row = mysql_fetch_array($result)) {
    echo "Table: {$row['table_name']} - {$row['create_time']} <br/>";
}

Answer 2

使用information_schema表

select * from information_schema.columns
order by create_time, column_name, table_name;

或者，如果您想要更窄的结果集：

select column_name, table_name, data_type, character_maximum_length,
is_nullable, column_default, create_time
from information_schema.columns
order by create_time, column_name, table_name;

Answer 3

这可能是解决方案

select * from information_schema.columns
order by create_time, column, table;
