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];

declare @myColumn   as nvarchar(128)
set @myColumn = 'myColumn'
if not exists (
    select  1
    from    information_schema.columns columns 
    where   columns.table_catalog   = 'myDatabase'
        and columns.table_schema    = 'mySchema' 
        and columns.table_name      = 'myTable' 
        and columns.column_name     = @myColumn
    )
begin
    exec('alter table myDatabase.mySchema.myTable add'
    +'    ['+@myColumn+'] bigint       null')
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

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';

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') 

以下查询可用于检查表中是否存在搜索列。我们可以根据搜索结果做出决定，如下所示。

IF EXISTS (SELECT 'Y' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = <YourTableName> AND COLUMN_NAME = <YourColumnName>)
  BEGIN
    SELECT 'Column Already Exists.'
  END
  ELSE
  BEGIN
    ALTER TABLE <YourTableName> ADD <YourColumnName> <DataType>[Size]
  END
