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...
所谓动态SQL即SQL的内容是灵活的,是通过字符串拼接出来的,可以理解是不固定的。比如有一个需求,我们想通过查询指定表的字段名并以列的形式展示出来,这里就可以通过存储过程结合动态SQL来实现。因为每次传过来的参数即表名是不固定的,所以需要一个字符串变量拿到参数里的值再拼接成最终的sql(相对于翻译一下),再去数...

TSQL–临时表和表变量 1. 临时表适用数据量较大的情况,因为临时表可以建立索引 2. 表变量适用于数据较小的情况,表变量只能在定义时创建约束(PRIMARY KEY/UNIQUE)从而间接建立索引 3. 临时表是事务性的,数据会随着事务回滚而回滚,表变量是非事务性的
When creating a natively compiled stored procedure, rather than using a cursor, use set-based logic or a WHILE loop. Feature Non-constant parameter defaults When using default values with parameters on natively compiled stored procedures, the values must be constants. Remove any wildcards from the...
