试试这个

SELECT COLUMNS.*
FROM   INFORMATION_SCHEMA.COLUMNS COLUMNS,
       INFORMATION_SCHEMA.TABLES TABLES
WHERE  COLUMNS.TABLE_NAME = TABLES.TABLE_NAME
       AND Upper(COLUMNS.COLUMN_NAME) = Upper('column_name') 

首先检查dbo.syscolumns（包含字段定义的内部SQL Server表）中是否存在表/列（id/name）组合，如果不存在，则发出适当的ALTER table查询以添加它。例如：

IF NOT EXISTS ( SELECT  *
            FROM    syscolumns
            WHERE   id = OBJECT_ID('Client')
                    AND name = 'Name' ) 
ALTER TABLE Client
ADD Name VARCHAR(64) NULL

执行以下查询以检查给定表中是否存在该列：

IF(SELECT COLUMN_NAME from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = 'TableName' AND COLUMN_NAME = 'ColumnName') IS NOT NULL
PRINT 'Column Exists in the given table';

您可以一次检查SQLDB中的多个列，并返回一个字符串作为状态以检查列是否存在：

IF EXISTS
        (
          SELECT *
          FROM INFORMATION_SCHEMA.COLUMNS
          WHERE TABLE_NAME = 'Table Name'
          AND(COLUMN_NAME = 'column 1'
          or COLUMN_NAME = 'column 2'
          or COLUMN_NAME = 'column 3'
          or COLUMN_NAME = 'column 4')
        )
        SELECT 'Column exists in table' AS[Status];
        ELSE
        SELECT 'Column does not exist in table' AS[Status];

接受答案的临时表格版本：

if (exists(select 1
           from tempdb.sys.columns
           where Name = 'columnName'
                 and Object_ID = object_id('tempdb..#tableName')))
begin
...
end

Wheat的答案很好，但它假设您在任何模式或数据库中都没有任何相同的表名/列名对。为了确保安全，使用这个。。。

select *
from Information_Schema.Columns
where Table_Catalog = 'DatabaseName'
  and Table_Schema = 'SchemaName'
  and Table_Name = 'TableName'
  and Column_Name = 'ColumnName'
