当前回答
SELECT table_schema + '.' + table_name,
column_name
FROM [yourdatabase].information_schema.columns
WHERE column_name LIKE '%myName%'
这将为您提供需要查找的列的表名。

为了改进上面的答案,我还包括了视图,并将模式和表/视图连接在一起,使结果更加明显。
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]
WHEN [T].[NAME] = ''
THEN [V].[NAME]
ELSE [T].[NAME]
END + ']' AS [TABLE], [C].[NAME] AS [COLUMN]
FROM [SYS].[SCHEMAS] AS [S] LEFT JOIN [SYS].[TABLES] AS [T] ON [S].SCHEMA_ID = [T].SCHEMA_ID
LEFT JOIN [SYS].[VIEWS] AS [V] ON [S].SCHEMA_ID = [V].SCHEMA_ID
INNER JOIN [SYS].[COLUMNS] AS [C] ON [T].OBJECT_ID = [C].OBJECT_ID
OR
[V].OBJECT_ID = [C].OBJECT_ID
INNER JOIN [SYS].[TYPES] AS [TY] ON [C].[SYSTEM_TYPE_ID] = [TY].[SYSTEM_TYPE_ID]
WHERE [C].[NAME] LIKE @COLUMNNAME
GROUP BY '[' + [S].[NAME] + '].' + '[' + CASE
WHEN [T].[NAME] IS NULL
THEN [V].[NAME]
WHEN [T].[NAME] = ''
THEN [V].[NAME]
ELSE [T].[NAME]
END + ']', [T].[NAME], [C].[NAME], [S].[NAME]
ORDER BY '[' + [S].[NAME] + '].' + '[' + CASE
WHEN [T].[NAME] IS NULL
THEN [V].[NAME]
WHEN [T].[NAME] = ''
THEN [V].[NAME]
ELSE [T].[NAME]
END + ']', CASE
WHEN [T].[NAME] IS NULL
THEN 'View'
WHEN [T].[NAME] = ''
THEN 'View'
ELSE 'Table'
END, [T].[NAME], [C].[NAME];
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 '%Label%'
ORDER BY schema_name, table_name;
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 '%EmployeeID%'
ORDER BY schema_name, table_name;

此外,还可以找到具有指定模式的列名。
SELECT 'DBName' AS DBName,
column_name,
table_name,
table_schema
FROM dbname.information_schema.columns
WHERE column_name LIKE '%YourColumnName%'
AND table_schema IN ( 'YourSchemaName' )
您还可以在多个数据库中找到同一列。
SELECT 'DBName1' AS DB,
column_name,
table_name,
table_schema
FROM dbname1.information_schema.columns
WHERE column_name LIKE '%YourColumnName%'
UNION
SELECT 'DBName2' AS DB,
column_name,
table_name,
table_schema
FROM dbname2.information_schema.columns
WHERE column_name LIKE '%YourColumnName%'
希望这不是一个重复的答案,但我想做的是在sql语句中生成一个sql语句,这将允许我搜索我要查找的值(而不仅仅是具有这些字段名称的表(因为通常我需要删除与我要查找列名称的id相关的任何信息):
SELECT 'Select * from ' + t.name + ' where ' + c.name + ' = 148' AS SQLToRun
FROM sys.columns c, c.name as ColName, t.name as TableName
JOIN sys.tables t
ON c.object_id = t.object_id
WHERE c.name LIKE '%ProjectID%'
然后我可以复制并粘贴运行我的第一列“SQLToRun”。。。然后我将“Select*from”替换为“Delete from”,它允许我删除对该给定ID的任何引用!将这些结果写入文件,以备不时之需。
注意***在运行delete语句之前,请确保消除所有bakup表。。。
SELECT 'Delete from ' + t.name + ' where ' + c.name + ' = 148' AS SQLToRun
FROM sys.columns c, c.name as ColName, t.name as TableName
JOIN sys.tables t
ON c.object_id = t.object_id
WHERE c.name LIKE '%ProjectID%'
