Question

我有一个表“燃料”，它有一行，这是一个主键，名为“fuel_id”，该字段是自动增量。还有3行是典型的字符串。当我插入数据时，它会抛出一个异常，即参数索引超出范围。任何帮助将不胜感激。

只是为了确保我的插入字符串是：

"INSERT INTO fuels (fuel_id, fuel_type, price, date) VALUES (?, ?, ?, ?)"

试试这个

INSERT INTO fuels (fuel_type, price, date) VALUES (?, ?, ?)

当作为自动增量的表列不包含在插入查询中时，当您通过此查询插入记录时，将自动插入fuel_id列值。

MySQL索引超出自动增量范围
