最简单易懂的解决方案之一是：

IF COL_LENGTH('Table_Name','Column_Name') IS NULL
  BEGIN
    -- Column Not Exists, implement your logic
  END
ELSE
  BEGIN
    -- Column Exists, implement your logic
  END

下面是我用来管理数据库中列添加的简单脚本：

IF NOT EXISTS (
        SELECT *
        FROM sys.Columns
        WHERE Name = N'QbId'
            AND Object_Id = Object_Id(N'Driver')
        )
BEGIN
    ALTER TABLE Driver ADD QbId NVARCHAR(20) NULL
END
ELSE
BEGIN
    PRINT 'QbId is already added on Driver'
END

在此示例中，Name是要添加的ColumnName，Object_Id是TableName

试试这个。。。

IF NOT EXISTS(
  SELECT TOP 1 1
  FROM INFORMATION_SCHEMA.COLUMNS
  WHERE 
    [TABLE_NAME] = 'Employees'
    AND [COLUMN_NAME] = 'EmployeeID')
BEGIN
  ALTER TABLE [Employees]
    ADD [EmployeeID] INT NULL
END

IF EXISTS (
SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_CATALOG = 'Database Name'
and TABLE_SCHEMA = 'Schema Name'
and TABLE_NAME = 'Table Name'
and COLUMN_NAME = 'Column Name'
and DATA_TYPE = 'Column Type') -- Where statement lines can be deleted.

BEGIN
  -- Column exists in table
END

ELSE BEGIN
  -- Column does not exist in table
END

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';

select distinct object_name(sc.id)
from syscolumns sc,sysobjects so  
where sc.name like '%col_name%' and so.type='U'
