As the name suggests: table-valued returns table, however Scalar-valued returns a single value, such as a string, integer, or bit value. 1、table-valued function As to create table-valued function, there are 2 ways, look at the example below please, it’s suitable for simple logic: USE...
自定义函数(User-Defined Function)有两种,一种是标量UDF(Scalar-valued Functions)和表值UDF(Table-valued Functions),前者只返回单个数据值,而后者则返回一个表。下面示例是,是属于前者,返回单个值。 代码
Table Update是一个物理运算符。 Table-valued FunctionTable-valued Function运算符计算表值函数(Transact-SQL 或 CLR)并将结果行存储在tempdb数据库中。 当父迭代器请求这些行时,Table-valued Function将返回tempdb中的行。 调用表值函数的查询生成具有Table-valued Function迭代器的查询计划。 可以使用不同的参数值计...
Table-valued functions can return a table when: Created from scalar input arguments. For example, a table-valued function that takes a comma-delimited string of numbers and pivots them into a table. Generated from external data. For example, a table-valued function that reads the event log an...
ufnGetSalesOrderStatusText SQL_SCALAR_FUNCTION ufnGetCustomerInformation SQL_INLINE_TABLE_VALUED_FUNCTION 通过右键单击结果网格并选择“连同标题一起复制”选项,我可以共享此输出。 正如午夜电视广告所说,“且慢! 还有更多精彩内容!” 编辑器窗口也有上下文菜单(见图 6)。
function_body 仅用于标量函数和多语句表值函数。 在标量函数中,function_body 是一系列 Transact-SQL 语句,这些语句一起使用的计算结果为标量值。 在多语句表值函数中,function_body 是一系列 Transact-SQL 语句,这些语句将填充 TABLE 返回变量。 scalar_expression 指定标量函数返回标量值。 TABLE 指定表值函数的...
