Найти все таблицы, содержащие столбец с указанным именем - MS SQL Server

Question

Можно ли запросить имена таблиц, которые содержат столбцы

LIKE '%myName%'

?

Answer 1

Вы можете попробовать этот запрос:

USE AdventureWorks
GO
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 '%myName%'

Просто чтобы улучшить ответы, приведенные выше, я также включил виды и объединил схему и таблицу / вид, сделав результаты более наглядными.

DECLARE @COLUMNNAME AS VARCHAR(100);

SET @COLUMNNAME = '%Absence%';

SELECT CASE
           WHEN [T].[NAME] IS NULL
           THEN 'View'
           WHEN [T].[NAME] = ''
           THEN 'View'
           ELSE 'Table'
       END AS [TYPE], '[' + [S].[NAME] + '].' + '[' + CASE
                                                          WHEN [T].[NAME] IS NULL
                                                          THEN [V].[NAME]

Create table #yourcolumndetails(
DBaseName varchar(100), 
TableSchema varchar(50), 
TableName varchar(100),
ColumnName varchar(100), 
DataType varchar(100), 
CharMaxLength varchar(100))

EXEC sp_MSForEachDB @command1='USE [?];
    INSERT INTO #yourcolumndetails SELECT
    Table_Catalog
    ,Table_Schema
    ,Table_Name
    ,Column_Name
    ,Data_Type
    ,Character_Maximum_Length
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE COLUMN_NAME like ''origin'''

select * from #yourcolumndetails
Drop table #yourcolumndetails

Вот рабочее решение для базы данных Sybase

select 
  t.table_name, 
  c.column_name 
from 
  systab as t key join systabcol as c 
where 
   c.column_name = 'MyColumnName'
