#mysql遇到的坑

  • mysql中%s的参数中不要传数字值,会引起mysql warning; mysql Warning | 1292 | Truncated incorrect DOUBLE value: '25a3c516a4c15eda917963e48a254' | 可能造成的原因:on running a MySQL query, it could be caused by using a numeric value against a CHAR/VARCHAR column.

  • executemany使用时,传的参数必须是元祖

  • fetchone返回的是dict

  • fetchall返回是元祖。所以取值时,需要先fd[0]["information"]
