我如何在AS3一个布尔值是否一个表或数据库中的一个条目存在?
How do I get a Boolean value in AS3 whether a table or an entry exists in the database?
至于反对与SQL手动找到它,你应该使用内置的架构信息类/功能。这里是它如何工作的例子。
As opposed to finding it manually with SQL you should use the built in Schema information classes/functions. Here is an example of how it would work.
public function doesTableExist(connection:SQLConnection, tableName:String):Boolean
{
connection.loadSchema();
var schema:SQLSchemaResult = connection.getSchemaResult();
for each (var table:SQLTableSchema in schema.tables)
{
if (table.name.toLowerCase() == tableName.toLowerCase())
{
return true;
}
}
return false;
}
