但在其他数据库中搜索search_mp3s，例如'db2'。我如何才能与我的情况建立关系？谢谢

Answer 1

在纯SQL中，这应该是using System.ComponentModel.DataAnnotations;。并且您必须具有允许从两个数据库读取的用户连接。

我不知道，kohana理解from PyPDF2 import PdfFileMerger, PdfFileReader, PdfFileWriter file1 = PdfFileReader(open('good_old.pdf', "rb")) output = PdfFileWriter() page = file1.getPage(0) page.mergePage(file1.getPage(1)) outputStream = open("great_new.pdf", "wb") output.write(outputStream) outputStream.close()符号...... 您可以在模型（ORM）类中尝试：

database.table.field

如何在其他数据库中使用表来“通过”kohana ORM？
