 1.查看当前数据库中的UDF列表

SELECT name,type_desc,definitionFROM sys.sql_modules sINNER JOIN sys.objects o	ON s.object_id=o.object_idWHERE TYPE IN('IF','TF','FN')--IF为内联表UDF,TF为多语句表UDF,FN为标量UDF

sys.sql_modules和sys.objects系统视图用来在查询的结果集中返回UDF名、类型描述以及SQL定义。

2. 删除一个用户定义函数用DROP:

  DROP FUFICTION( [schema_name.] function_narne} [,…n]

例如:

DROP FUNCTiON dbo.udf_ParseArray

可以删除多个UDF

DROP FUNCTiON     dbo.udf_ParseArray,    dbo.udf_ReturnEmployeeAddress,    dbo.udf_CheckFroSQLInjection
