sfs 2x執行SQL語法

在sfs 2x執行SQL語法
是透過IDBManager物件來處理
如果要傳入參數給SQL語法的話
要用PreparedStatement物件來處理

 

取出陣列，直接傳給Client

IDBManager dbManager = getParentExtension().getParentZone().getDBManager();
String sql = "SELECT * FROM people";
 
try
{
ISFSArray res = dbManager.executeQuery(sql);
 
ISFSObject response = new SFSObject();
response.putSFSArray("people", res);
 
send("getPeople", response, sender);
}
catch (SQLException e)
{
trace(ExtensionLogLevel.WARN, "SQL Failed: " + e.toString());
}
