目前分散式開發,比較不強調使用Stored Procedure,而是Data Access Layer僅做單純存取SQL Server,邏輯則寫在BLL,若你有以下的需求,則Stored Procedure仍然適合你。 Introduction 1.SQL Script Reuse: 使用Class寫法僅能達到C#部分的程式碼重複使用,若要達到SQL部分的程式碼重複使用,就必須將SQL寫在Stored Procedure裡。 2...

Azure SQL 托管实例 本主题列出了 T-SQL 的外围应用以及本机编译 T-SQL 模块主体支持的功能,如存储过程 (CREATE PROCEDURE (Transact-SQL))、标量用户定义函数、内联表值函数和触发器。 有关本机模块定义的支持功能,请参阅对于本机编译的 T-SQL 模块支持的 DDL。
SQL Server 2016 返回 stored_procedure_name Transact-SQL 语法约定 语法 syntaxsql 复制 ERROR_PROCEDURE ( ) 返回类型 nvarchar(128) 返回值 在CATCH 块中调用时,ERROR_PROCEDURE 返回导致错误的存储过程或触发器的名称。 如果存储过程或触发器中未出现该错误,ERROR_PROCEDURE 返回NULL。 在CATCH 块作用域外调...
Put my procedure execution script that I copied from SQL. And run the script with debugging. Everything works normal up to this point and the procedure goes into debug mode. But when I try to debug the “exec” function that calls the procedure, pressing F11 key, the visu...
A common scenario where table-valued parameters are very useful is passing an “array” of keys to a stored procedure. Before SQL Server 2008, common ways to meet this need were based on dynamic SQL, a split function, XML, and other techniques. The approach using dynamic SQL involved the ...
I created a script fillCheckRank and a stored procedure spu_testRecursion. The script creates and loads table checkRank with relatively random data (see CreateCheckRank.sql in theDownload file), but the stored procedure (see Listing 1) is more complex and uses a recursive algorithm, nested p...
