运行查询:

    SP_RENAME '[TableName].[ColumnName]','NewNameForColumn'

使用sp_rename

EXEC sp_RENAME 'TableName.OldColumnName' , 'NewColumnName', 'COLUMN'

参见:SQL SERVER -如何重命名列名或表名

文档:sp_rename (Transact-SQL)

对于您的情况，它将是:

EXEC sp_RENAME 'table_name.old_name', 'new_name', 'COLUMN'

记住使用单引号将值括起来。

Try:

EXEC sp_rename 'TableName.OldName', 'NewName', 'COLUMN'

你还应该指定表的模式，否则你可能会得到这个错误:

Msg 15248，级别11，状态1，过程sp_rename，第238行 参数@objname不明确或者声明的@objtype (COLUMN)不明确 错了。

如果它是一个部署脚本，我还建议添加一些额外的安全性。

IF EXISTS (
        SELECT 1
        FROM sys.columns
        WHERE
            name = 'OldColumnName' AND
            object_name(object_id) = 'TableName'
    ) AND
    NOT EXISTS (
        SELECT 1
        FROM sys.columns
        WHERE
            name = 'NewColumnName' AND
            object_name(object_id) = 'TableName'
    )
    EXEC sp_RENAME 'SchemaName.TableName.OldColumnName', 'NewColumnName', 'COLUMN';

@Taher的改进版本

DECLARE @SchemaName AS VARCHAR(128)
DECLARE @TableName AS VARCHAR(128)
DECLARE @OldColumnName AS VARCHAR(128)
DECLARE @NewColumnName AS VARCHAR(128)
DECLARE @ParamValue AS VARCHAR(1000)

SET @SchemaName = 'dbo'
SET @TableName = 'tableName'
SET @OldColumnName = 'OldColumnName'
SET @NewColumnName = 'NewColumnName'
SET @ParamValue = @SchemaName + '.' + @TableName + '.' + @OldColumnName

IF EXISTS
(
    SELECT 1 FROM sys.columns WHERE name = @OldColumnName AND OBJECT_NAME(object_id) = @TableName
)
AND NOT EXISTS
(
    SELECT 1 FROM sys.columns WHERE name = @NewColumnName AND OBJECT_NAME(object_id) = @TableName
)
BEGIN
    EXEC sp_rename @ParamValue, @NewColumnName, 'COLUMN';
END

或者你可以在SQL Management Studio中慢点两次列并通过UI重命名它…
