如果要删除的函数被使用WITH SCHEMABINDING选项创建的视图或其他函数引用,则DROP FUNCTION将失败。 要删除多个函数: DROP FUNCTION [IF EXISTS] schema_name.function_name1, schema_name.function_name2, ...; 1. 2. 3. 4. 示例 A)删除普通函数 比如删除udfContacts: DROP FUNCTION IF EXISTS udfContacts; 1....
第三步:在 SQL Server 中测试函数 最后,我们可以通过一个测试脚本来调用这个函数,查看其是否正常工作。 DECLARE@DataMyTableType;INSERTINTO@Data(ID,Name)VALUES(1,'Alice'),(2,'Bob'),(3,'Charlie');DECLARE@ResultINT;SET@Result=dbo.MyFunction(@Data);SELECT@ResultASTotalCount; 1. 2. 3. 4. 5....
Cannot process the query because it references the common language runtime (CLR) table-valued function "yUtl.clr_GetFolderList" with a hint through view "yUtl.v_test". 其实这个是因为视图对象使用了WITH(NOLOCK)的话,就会自动转换为给视图内部对象加上WITH(NOLOCK),那么就会出现上面的错误,如果像存储...
A table-valued function is a user-defined function that returns a table. SQL Server extends the functionality of table-valued functions by allowing you to define a table-valued function in any managed language. Data is returned from a table-valued function through an IEnumerable or IEnumerator ...
Applies to: SQL Server A scalar-valued function (SVF) returns a single value, such as a string, integer, or bit value. You can create scalar-valued user-defined functions in managed code using any .NET Framework programming language. These functions are accessible ...
在SQL server中不仅可以可以使用系统自带的函数(时间函数、聚合函数、字符串函数等等),还可以根据需要自定义函数。 一、定义: 用户自定义函数的类型: 1、标量值函数(返回一个标量值) 2、表格值函数(内联表格值函数、多语句表值函数,返回一个结果集即返回多个值) ...
