20:45:54 call book_rental(1, 5, 2, 50.00, 2, 2, 5.00, 3, 4, 2.00, 4, 2, 10.00, '现金', '2016-01-01', '2016-01 -05') 错误代码：1292。不正确的日期时间值：第 1 行的列 'date' 的 '2014' 0.265 秒

这是代码。请帮忙！

在将值传递给准备好的语句时，您应该使用参数。但是，如果不是，日期需要用单引号括起来。所以，而不是：

SET @item1inv = CONCAT('UPDATE running_inventory SET `', item1_id, '` = `', item1_id, '` - ', item1_qty, ' WHERE date = ', invdate);

它应该是：

SET @item1inv = CONCAT('UPDATE running_inventory SET `', item1_id, '` = `', item1_id, '` - ', item1_qty, ' WHERE date = ''', invdate, '''');
