我有一个需要连接在一起的三个 SQLite 数据库。我已经尝试过以下程序:
(1)SELECT column1, column2, quote(column3) from table1 - quote(X) is to convert blob field into string field
(2)I import table1.csv back into database, where i define first two fields as INTEGERin third as STRING
(3)I use: INSERT INTO table_new (column1, column2, column3) SELECT column1, column2, column3 FROM table1
但它不能正确转换(输出是图片.png)
应该有一个与 QUOTE 相反的函数并将我的转换数据返回给我?
非常感谢您的帮助 :)
