## **用途：**

**“Change Entries in Table”（更改表中的条目）工作流卡用于更新指定数据库表中的条目。您可以选择一个表**和一个**列**，然后使用指定的值对该列中的数值执行数学运算（加法、减法、乘法或除法）。

## **卡片组件：**

1. **表名称**
   * **说明：指定要更新条目的表**。
   * **详细信息：系统会提供可用表**的下拉列表，供您选择要更新条目的目标表。
2. **列名称**
   * **说明：指定所选表中要更新的列**。
   * **详细信息：系统会提供所有可用列**的列表供您选择。
3. **运算**
   * **说明：定义要对列**中的数值执行的数学运算。
   * **选项：**
     * **加法 (+)：将指定的值**加到所选列中的当前值上。
     * **减法 (-)：从所选列中的当前值中减去指定的值**。
     * **乘法 (\*)：将所选列中的当前值乘以指定的值**。
     * **除法 (/)：将所选列中的当前值除以指定的值**。
4. **值**
   * **说明：指定所选运算要使用的值**。
   * \*\*详细信息：\*\*这是要与所选列中的条目相加、相减、相乘或相除的数值。

## **功能：**

* **条件评估：**\
  仅当 **“Where”** 和 **“And Sections”** 的评估结果均为 true 时，此卡片才会执行操作。
* **更新表条目：**\
  此卡片会使用指定的**值**，对所选**表**中所选**列**的数值执行所选运算（**+**、**-**、**\*** 或 **/**）。

## **设置和配置：**

* **选择表：**\
  选择要应用更改的**表**。
* **选择列：**\
  选择表中要更新的**列**。
* **选择运算：**\
  选择要应用于所选列中数值的数学运算（**+**、**-**、**\***、**/**）。
* **输入值：**\
  输入所选运算要使用的**值**。

## **结论：**

**“Change Entries in Table”（更改表中的条目）工作流卡可通过选择表**、**列**和所需的**数学运算**，自动更新数据库条目。此卡片对于在数据库中执行批量数据修改或计算至关重要。

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.docbits.com/chinese/guan-li-yu-she-zhi/workflow/cards-overview/then/table/change-entries-with.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
