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...

When creating a natively compiled stored procedure, rather than using a cursor, use set-based logic or aWHILEloop. FeatureNon-constant parameter defaultsWhen using default values with parameters on natively compiled stored procedures, the values must be constants. Remove any wildcards from the parame...
When you create a database, SQL Server makes a copy of the model database, and renames the copy to the database name. This operation should only take several seconds, unless you specify a large initial size of the database as an optional parameter....
