获取有关数据库表列的元数据 2020 年 9 月 22 日，由 Robert Gravelle 撰写

某些关系数据库（包括 MySQL 和 SQL Server）具有 INFORMATION_SCHEMA 系统数据库。它包含数据库元数据，例如数据库名、表名、列数据类型，甚至访问权限。它有时也称为数据字典或系统目录。无论你如何称呼它，INFORMATION_SCHEMA 数据库都是获取有关表列详细信息的理想地方。在今天的文章中，我们将使用 INFORMATION_SCHEMA 数据库来查找列是否存在以及特定表具有多少列。

在Navicat中查看 INFORMATION_SCHEMA 数据库

作为系统表，除非你明确告诉 Navicat 显示它，否则你将无法看到 INFORMATION_SCHEMA 数据库。为此，请将 INFORMATION_SCHEMA 数据库添加到数据库连接中的“数据库”列表中：

这使我们可以在表设计器或查看器中打开 Columns 表：

纯粹列数应使你对我们可以从 Columns 表中获取哪些类型的信息有所了解。

注意：INFORMATION_SCHEMA 是一个只读数据库，因此你不能对其结构或内容进行任何更改。

列数查询简介

我们可以像查询其他表一样查询 Columns 表，以查找有关表列的信息。这是基本语法：

SELECT count(*) AS anyName FROM information_schema.columns 
WHERE [table_schema = 'yourSchemaName' AND] 
table_name = 'yourTableName';

table_schema 是表所在的数据库。这对查询不是至关重要的，但是如果你有多个具有相同列名的数据库，则会将结果过滤到该特定数据库表。在要维护同一数据库的多个副本的情况下，列计数会计算所有表中具有相同名称的列。

例如，我有四个 Sakila 数据库的副本：

结果，当我在不使用 table_schema 的情况下运行查询时，我得到的列数为 51，偏高！

指定 table_schema 以得到更准确的列数 12：

select_column_count_of_film_table_with_schema (40K)

如果现在在表设计器中打开 film 表，则可以确认 12 列是正确的：

确定是否存在列

在动态应用程序中，你可能希望查找有关列的信息，包括其是否存在。以下的查询列出了“title”列的每个实例和有关的元数据，包括其所属的模式和表，以及诸如默认值、数据类型和最大长度之类的详细信息：

总结

在今天的文章中，我们学习了如何利用 INFORMATION_SCHEMA 数据库来查找列是否存在以及特定表具有多少列
