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];

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

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

这在SQL Server 2000中对我有效：

IF EXISTS
(
    SELECT *
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE table_name = 'table_name'
    AND column_name = 'column_name'
)
BEGIN
...
END

另一个贡献是下面的示例，如果列不存在，则添加该列。

    USE [Northwind]
    GO

    IF NOT EXISTS(SELECT * FROM INFORMATION_SCHEMA.COLUMNS
                    WHERE TABLE_NAME = 'Categories'
                        AND COLUMN_NAME = 'Note')
    BEGIN

    ALTER TABLE Categories ADD Note NVARCHAR(800) NULL

    END
    GO

我需要类似于SQL Server 2000的东西，正如Mitch所指出的，这只适用于SQL Server 2005或更高版本。

这就是我最终的工作：

if exists (
    select *
    from
        sysobjects, syscolumns
    where
        sysobjects.id = syscolumns.id
        and sysobjects.name = 'table'
        and syscolumns.name = 'column')
