sql - 从数据库中的多个表中查找特定列（字段）名称

Question

我的数据库中有大量表。我正在搜索名为 的列Country，但不知道哪个表包含该列。是否有特定的查询可以帮助我找到包含该列的表的名称？

Answer 1

是的，您可以使用 INFORMATION_SCHEMA.COLUMNS

SELECT DISTINCT 
   TABLE_NAME 
FROM 
   INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME = 'Country'

Answer 2

SELECT t.name AS table_name,
SCHEMA_NAME(schema_id) AS schema_name,
c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
WHERE c.name LIKE '%ColumnName%'
ORDER BY schema_name, table_name;

替换ColumnName为您的实际列名

Answer 3

select distinct table_schema, table_name from information_schema.columns where table_name = 'Country';

Answer 4

您可以在INFORMATION_SCHEMA.COLUMNS

USE YourDBName;
SELECT DISTINCT Table_Name
FROM INFORMATION_SCHEMA.COLUMNS
WHERE Column_Name = 'Country';

Answer 5

如果我们想在多个表（例如：3 个表）中使用 like 运算符查找列名，请执行以下查询：

select COLUMN_NAME, TABLE_NAME 
from ALL_TAB_COLUMNS 
where TABLE_NAME in ('SIL_RLS_UPLOAD_TMP','SIL_CUSTOMER_MST','SIL_PERSONAL_CUSTOMER_MST')
      and upper(column_name) like upper('%loan%');

如果我们想在所有表中查找带有 like 运算符的列名，请执行以下查询：

select * 
from all_tab_columns 
where upper(column_name) like upper('%card%');
