如何获取文档类型，例如：地址或税收规则

Question

我想获取文档类型。我该怎么做呢？我想添加一个单独的列，它将提供销售订单、采购订单等文档类型。第一行给我错误应该触发什么查询。请帮助我是 ERP Next 的新手。

SELECT
    AD.ref_doctype AS “Doctype:Link/User:120”,
    AD.name AS “Doc#:Link/Doctype:120”,
    AD.owner AS “Created By:Link/User:120”,
    AD.modified AS “Modified On:Date:120”
FROM tabAddress AS AD

WHERE
    DATEDIFF(now(),AD.modified) BETWEEN 1 AND 30

UNION ALL

SELECT
    TR.name AS “Doc#:Link/Doctype:120”,
    TR.owner AS “Created By:Link/User:120”,
    TR.modified AS “Modified On:Date:120”
FROM tabTax Rule AS TR
WHERE
    DATEDIFF(now(),TR.modified) BETWEEN 1 AND 30

UNION ALL

SELECT
    IT.name AS “Doc#:Link/Doctype:120”,
    IT.owner AS “Created By:Link/User:120”,
    IT.modified AS “Modified On:Date:120”
FROM tabItem AS IT
WHERE
    DATEDIFF(now(),IT.modified) BETWEEN 1 AND 30

Answer 1

要获取文档类型名称，您必须提供链接的文档类型名称，例如， select IT.name 作为 "IT No:Link/IT:120"

Answer 2

我不太清楚你所说的 docType 字段是什么意思。

你想要这样的结果吗？

Doctype:Link/User:120|Doc#:Link/Doctype:120|Created By:Link/User:120|Modified On:Date:120|
---------------------|---------------------|------------------------|--------------------|
Email Account        |Jobs                 |Administrator           | 2019-12-04 06:07:55|
Email Account        |Notifications        |Administrator           | 2019-12-01 05:25:53|
Email Account        |Replies              |Administrator           | 2019-12-01 05:25:53|
Email Account        |Sales                |Administrator           | 2019-12-04 06:07:55|
Email Account        |Support              |Administrator           | 2019-12-04 06:07:55|

这是 select :

set @docType = "Email Account";
SELECT
    @tabDocType  AS `Doctype:Link/User:120`,
    AD.name AS `Doc#:Link/Doctype:120`,
    AD.owner AS `Created By:Link/User:120`,
    AD.modified AS `Modified On:Date:120`
FROM `tabEmail Account` AS AD

注意字段别名上的反引号！所有这些在SQL:

中都有不同的含义

"
'
`

最后一个反引号用于指代数据库实体。您试图将 “Doctype:Link/User:120” 与双引号一起使用，双引号声明纯文本。使用反引号将别名转换为可以从其他地方引用的数据库实体。

MariaDb 不允许直接将变量用作 table 名称，但您可以使用准备好的语句来实现，如下所示：

set @docType = "Email Account";
set @tabDocType = CONCAT('tab', @docType);
SET @sql_text = concat('

SELECT 
    "', @docType, '"  AS `Doctype:Link/User:120`
  , AD.name AS `Doc#:Link/Doctype:120`
  , AD.owner AS `Created By:Link/User:120`
  , AD.modified AS `Modified On:Date:120`
FROM `', @tabDocType, '` as AD;

');


PREPARE stmt FROM @sql_text;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

table 名称现在也由一个变量指定，该变量由 'tab' 与之前声明的 docType 串联而成。

您会得到与上述相同的结果，但是 - 您可以避免在以后编辑时不小心在一个地方更改 table 名称而在另一个地方不更改。
