问题描述：

升级nextcloud 到31.0.x，管理设置里提示“数据库中找到了不正确的行格式”，如图：

解决方案：

不管的话没什么问题，强迫症可以通过以下脚本解决：

#!/bin/bash

# Prompt for database credentials
read -p "Enter Database Name: " DB_NAME
read -p "Enter Username: " DB_USER
read -s -p "Enter Password: " DB_PASS
echo

# Execute all ALTER TABLE statements in one query
mysql -u "$DB_USER" -p"$DB_PASS" "$DB_NAME" -Bse "
SELECT CONCAT('ALTER TABLE \`', TABLE_NAME, '\` ROW_FORMAT=DYNAMIC;') 
FROM INFORMATION_SCHEMA.TABLES 
WHERE TABLE_SCHEMA = '$DB_NAME' 
AND ENGINE = 'InnoDB'
" | mysql -u "$DB_USER" -p"$DB_PASS" "$DB_NAME"
