V1.0.6 升级指南

哪些版本需要迁移？

当前版本低于 v1.0.6

为什么需要迁移？

V1.0.6 引入了元数据搜索功能，该功能基于 Mysql 的全文索引实现，历史数据没有建立相关索引会出现搜索不到的情况。

除了一次性迁移外，如果有以下操作也会自动建立索引

• 更新分组信息（任意字段）
• 更新项目信息（任意字段）
• 同步数据库成功（有新的版本产生）

如何迁移？

1. 部署 v1.0.6 版本应用，并启动
2. 登入数据库，执行以下迁移 SQL

-- migration group info
INSERT INTO document_full_text(group_id, group_name, group_description)
SELECT `group`.id, `group`.name, `group`.description
FROM `group`
         LEFT JOIN document_full_text dft ON `group`.id = dft.group_id
WHERE dft.group_id IS NULL
  AND `group`.deleted = FALSE;

-- migration project info
INSERT INTO document_full_text(group_id, project_id, project_name, project_description, database_name, schema_name,

         INNER JOIN database_document dd ON tcd.database_document_id = dd.id
         INNER JOIN project pj ON dd.project_id = pj.id
         INNER JOIN data_source ds ON pj.id = ds.project_id
WHERE pj.deleted = FALSE
  AND dd.is_archive = FALSE
  AND dft.table_column_document_id IS NULL
  AND dft.project_id IS NULL;

-- update table description;

UPDATE document_full_text
    LEFT JOIN document_description dd ON document_full_text.project_id = dd.project_id
SET table_description=dd.content
WHERE dd.table_name = document_full_text.table_name
  AND dd.project_id = document_full_text.project_id
  AND dd.column_name IS NULL;

-- update column description;
UPDATE document_full_text
    INNER JOIN document_description dd ON document_full_text.project_id = dd.project_id
SET col_description=dd.content

  AND dd.column_name = document_full_text.col_name
  AND dd.project_id = document_full_text.project_id
  AND dd.column_name IS NOT NULL;
