Question

我将应用程序从sqlite3迁移到MYSQL：在迁移表文件发生更改后，最初TABLE字段在sqlite3中是bool类型（在mysql中bool为tinyint）。

Traceback:

Exception Type: Warning at /reports/
Exception Value: Truncated incorrect DOUBLE value: 'True'

Answer 1

tinyint列不接受布尔值，将布尔值转换为整数：

intvalue = int(boolean_value)

分别为0和1存储False或True。

另一方面，0和1在布尔上下文中测试为false和true，因此您没有将它们转换回来。如果需要，您仍然可以使用bool()。

截断不正确的DOUBLE值：'True'
