像oracle一样，您可以通过以下方式查找表和列：

select table_name, column_name
from user_tab_columns 
where column_name 
like '%myname%';

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%'

它将返回table_name、schema_name、column_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 '%colName%'
ORDER BY schema_name,
table_name;

下面是Sybase数据库的工作解决方案

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

这应该是有效的：

SELECT name 
FROM sysobjects 
WHERE id IN ( SELECT id 
              FROM syscolumns 
              WHERE name like '%column_name%' )

SQL Server：

SELECT Table_Name, Column_Name 
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_CATALOG = 'YOUR_DATABASE'
AND COLUMN_NAME LIKE '%YOUR_COLUMN%'

神谕：

SELECT owner, table_name, column_name 
FROM all_tab_columns 
WHERE column_name LIKE '%YOUR_COLUMN_NAME%'
AND OWNER IN ('YOUR_SCHEMA_NAME');

就这么简单！！（SQL，PL/SQL）我一直使用它来查找给定数据库（模式）中列名的所有实例。
