起因: 这两个表中相同字段的位数不一样,一个是以固定长度(长度6位)的文本存储,一个是以整数存储(长度1~6位不等)。在C#里面,有String.Padleft函数可以处理这种问题,但可惜的是SQL Server里面没有 PadLeft: Create FunctionPadLeft(@OriginalString varchar(20),@PaddingCharchar(1),@TotalLengthint) ReturnsVarc...
实现SQL SERVER 下的PadLeft函数 在.net中,可以使用String.PadLeft函数右对齐字符串,在左边用指定的Unicode字符填充一达到指定的总长度。 例如 在做自动编号这样使用 int nextID=da.GetMaxNum()+1; this.txtCode.Text = nextID.ToString().PadLeft(6, '0'); 今天客户想要在用户表里加个工号字段,这个字段是...
Here is my method for achieving left and right string padding in the Microsoft SQL Server T-SQL language. Unfortunately T-SQL does not offer functions like Oracle PL/SQL's LPAD() and RPAD() and C#'s PadLeft() and PadRight() functions. However, you can achieve the same thing using the...

當您使用這些方法的其中之一在DataAdapter更新期間保留DataRow中的原始值時,Microsoft SqlClient Data Adapter for SQL Server 會執行一系列的動作,將DataRow的目前值設定為輸出參數所傳回的新值,或設定為結果集第一個傳回的資料列所傳回的新值,同時仍然保留每個DataColumn中的原始值。 首先,系統會呼叫AcceptChanges的...

Microsoft SQL Server uses reserved keywords for defining, manipulating, and accessing databases. Reserved keywords are part of the grammar of the Transact-SQL language that is used by SQL Server to parse and understand Transact-SQL statements and batches. Although it is syntactically possible to use...
If you currently use another database management system (DBMS), you can migrate to Microsoft SQL Server. Migrating from another DBMS to SQL Server involves transferring not only the data stored in the DBMS, but the databases and tables that hold the data, and other objects that interact with...
