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';

if exists (
  select * 
  from INFORMATION_SCHEMA.COLUMNS 
  where TABLE_NAME = '<table_name>' 
  and COLUMN_NAME = '<column_name>'
) begin
  print 'Column you have specified exists'
end else begin
  print 'Column does not exist'
end

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];

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')

我的一位好朋友和同事向我展示了如何在SQL Server 2005和更高版本中使用带有SQL函数OBJECT_ID和COLUMNPROPERTY的IF块来检查列。您可以使用类似于以下内容的内容：

你可以在这里看到：

IF (OBJECT_ID(N'[dbo].[myTable]') IS NOT NULL AND
    COLUMNPROPERTY( OBJECT_ID(N'[dbo].[myTable]'), 'ThisColumnDoesNotExist', 'ColumnId') IS NULL)
BEGIN
    SELECT 'Column does not exist -- You can add TSQL to add the column here'
END

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
