行大小太大 (> 8126)

Question

我面临以下问题。

Row size too large (> 8126). Changing some columns to TEXT or BLOB or using ROW_FORMAT=DYNAMIC or ROW_FORMAT=COMPRESSED may help. In

当前行格式，768 字节的 BLOB 前缀内联存储。

它出现在我将图像上传到数据库时（它具有 <1Mb）。准确地说，只有 100kb。

我尝试了很多事情：更改属性“max_allowed_pa​​cket”、“innodb_log_file_size”（即，将大小增加到 512M）并没有什么......

我不知道麻烦的原因。

为了说明，表

Bill Karwin之前在他对MySQL 的 Row size error 的回答中已经解决了这个问题

我过去也解决过这个问题：MySQL: Row size too large (> 8126)

根据他的帖子，以及您仍然有几个 TEXT 和 VARCHAR 字段的事实，您应该将以下值设置为更高my.cnf：

[mysqld]
max_allowed_packet = 1G
innodb_log_file_size = 2G
innodb_log_buffer_size = 512M

然后，重新启动mysqld。

你的评论

在绝望中，我昨天删除了所有的 blob 列。我只留下一个。问题消失了。但是我会再次创建它们并尝试您的方法。我尽快带着结果回来。谢谢指点

您不应将 20 BLOB 放在一张表中。您应该创建表来保存 BLOB

CREATE TABLE mi_fotos
(
    id INT NOT NULL AUTO_INCREMENT,
    passeio INT NOT NULL,
    foto BLOB,
    PRIMARY KEY (id)
) ENGINE=InnoDB;

将您的照片存储在此表中，并将此表中的 passeio 链接回您的原始表。
