我已阅读有关此错误的所有其他相同问题。但是我找不到正确的解决方案来修复 MySQL 服务器 8.0.13 的错误。请帮忙。
我有下表，其中包含大约 255 个 MEDIUMTEXT 类型的列

但这给我带来了错误-
Error Code: 1118. Row size too large (> 8126). Changing some columns to TEXT or BLOB may help. In current row format, BLOB prefix of 0 bytes is stored inline
我尝试了其他替代解决方案，例如调整 my.ini 文件，例如将 innodb_log_file_size 增加到 2G、5G 等任何范围，但这些调整都没有成功。
此外，我不想只关闭 innodb_strict_mode，因为我不认为关闭验证是唯一的解决方案。对于 MYSQL 服务器 8.0.13 版，任何人对此类表的任何其他解决方案。
最佳答案
您设计了一种愚蠢的表格，已经达到了尺寸限制，抱歉!当您有这样的“数组”方案时，您应该规范化 — SQL 就是为您设计的。
您需要展平现有的表格。而不是 (id, val1, val2, val3, val4, ...)，您需要 (id, 1, val), (id, 2, val), (id, 3 , val), ....使用此方案，您不会达到大小限制，并且您有一个更加惯用的架构。
您还需要考虑到 status 字段，所以我们最终得到这样的结果:
CREATE TABLE `guidatatable` (
`id` INT NOT NULL AUTO_INCREMENT,
`status` INT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB;
CREATE TABLE `guidatatable_values` (
`id` INT NOT NULL,
`colNum` INT NOT NULL,
`colValue` MEDIUMTEXT NOT NULL,
PRIMARY KEY (`id`, `colNum`)
) ENGINE=InnoDB;
并且确保使 guidatatable_values.id 成为引用 guidatatable.id 的外键(我忘记了这个副手的最佳语法)。
数据转换的具体例子；这个:
id col01 col02 col03 status
1 Hello World ! 42
2 How Are You 99
3 I Am Fine 168
变成这样:
id status
1 42
2 99
3 168
id colNum colValue
1 1 Hello
1 2 World
1 3 !
2 1 How
2 2 Are
2 3 You
3 1 I
3 2 Am
3 3 Fine
如您所见，表中存储的所有语义和关系信息都保持不变；它刚刚被重组。
一般来说，一旦达到最大表格大小，您就会知道表格太大并且可能可以进行更好的设计。这尤其可能发生在大型应用程序中，在这些应用程序中，遗留需求导致表不断增长……同样，这通常是未能充分设计新功能的一个例子。
