在MySQL5.7.7以前innodb_file_format参数默认是Antelope,而默认的行格式是(ROW_FORMAT)是COMPACT,从MySQL5.7.7以后版本innodb_file_format默认值为Barracuda,默认的行格式是(ROW_FORMAT)是DYNAMIC,所以需要在创建表结构时指定row_format=compact从MySQL5.7.7版本中innodb_file_format参数(该参数表示innodb文件格式)的默认...
今天线上版本的错误: Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Row size too large (> 8126). Changing some columns to TEXT or BLOB or using ROW_FORMAT=DYNAMIC or ROW_FORMAT=COMPRESSED may help. In current row format, BLOB prefix of 768 bytes is stored inline. 【...
innodb默认格式是row_format=compact ,插入大于8126的数据会报错:Row size too large (> 8126). Changing some columns to TEXT or BLOB or using ROW_FORMAT=DYNAMIC or ROW_FORMAT=COMPRESSED may help. In current row format, BLOB prefix of 768 bytes is stored inline. 可以通过修改my.cnf文件,指定row_...
1.打开mysql的配置my.ini.在innodb配置中添加:innodb_file_per_table=1,(大概意思就是打开mysql每张表都是独立存储空间的开关)如下图: 2.然后命令检查上述开关是否打开: value 值显示 ON 就是打开了 4.设置对应表的属性:ROW_FORMAT=DYNAMIC 选择dynamic 行格式,重启动mysql 就可以了。
要将MySQL中的row_format修改为dynamic,可按以下语法进行操作: ALTERTABLEyourTableName ROW_FORMAT=DYNAMIC; SQL 让我们首先创建一个表: mysql>createtableDemoTable(CustomerIdintNOTNULLAUTO_INCREMENTPRIMARYKEY,CustomerNamevarchar(200),CustomerAgeint,CustomerAddressvarchar(200));QueryOK,0rowsaffected(0.73sec) ...
Row_format= Dynamic. 5.7's code checks innodb_file_format only when ROW_FORMAT= Compressed.https://github.com/mysql/mysql-server/blob/mysql-5.7.16/storage/innobase/handler/ha_innodb...5.6's one checks both when ROW_FORMAT= Compressed and ROW_FORMAT= Dynamic.https://github.com/mysql/mysql...
4. 解决方案二:使用row_format=dynamic或row_format=compressed 对于InnoDB存储引擎,可以通过改变行格式来解决行尺寸过大的问题。DYNAMIC和COMPRESSED行格式允许将更多的数据存储在外部页面中,从而减小行内数据的尺寸。 将表的行格式改为DYNAMIC: sql ALTER TABLE your_table_name ROW_FORMAT=DYNAMIC; ...
