问题 Here's what I am trying to do. I will change the following code into SP which takes two parameter @startdate, and @transactionDate, and it will return the NextTransactiondate. The logic is @startdate determine which day of the week it is. The @NexttransactionDate should be equal to the day following the transactiondate. so in this example, the startday is Wednesday so the next transaction date should be - 2011-05-04'. In the code below, it is always computing to friday, but it should be

问题 Below I have shown two tables and also the result table. How can I get the result table in this manner as I shown on above? 回答1: select min(ID) as ID, Val, stuff((select ','+Cat from Table2 as T2 where T1.Val = T2.Val for xml path(''), type).value('.', 'nvarchar(max)'), 1, 1, '') as Cat from Table2 as T1 group by Val order by ID SQL Fiddle 回答2: DECLARE @Table1 TABLE ( id INT ,Val VARCHAR(100) ) DECLARE @Table2 TABLE ( id INT ,Val VARCHAR(100) ,Cat VARCHAR(100) ) INSERT INTO @Table1 VALUES(1,

问题 How can I query data in the order it was created? I don't have a date-created field in this table. 回答1: If you don't have a field storing the time of insertion, or any other meta-data regarding the order of insertion, there is no reliable way to get this information. You could maybe depend on a clustered index key, but these are not guaranteed. Neither are IDENTITY fields or other auto-generated fields. To clarify, an IDENTITY field does auto-increment, but... You can insert explicit values

问题 This is my very first T-SQL question, so I hope I'm not using the wrong terminology. I just learned some basic stored procedures and variable declaration, however there is something I haven't understood. DECLARE @CurrentDate DATETIME SET @CurrentDate = GETDATE() select @CurrentDate ----------------------- 2013-09-25 18:47:07.547 (1 row(s) affected) If I running the above in two batches ( declare and set together, select after) I get: DECLARE @CurrentDate DATETIME SET @CurrentDate = GETDATE()

问题 I would like to insert data from a file into the table Division of this model which is very much simplified: create table Statements ( Id INT IDENTITY NOT NULL primary key (Id) ) create table Item ( StatementFk INT not null, ItemNameFk INT not null, primary key (StatementFk) ) create table ItemNames ( Id INT not null, Name NVARCHAR(255) null unique, primary key (Id) ) create table Division ( ItemFk INT not null, primary key (ItemFk) ) alter table Item add constraint FKBCDC2F95A77158D3 foreign

问题 I am working on a search query that does not seem to work. The complete query is: set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go ALTER PROCEDURE [dbo].[usp_Item_Search] @Item_Num varchar(30) = NULL ,@Search_Type int = NULL ,@Vendor_Num varchar(10) = NULL ,@Search_User_ID int = NULL ,@StartDate smalldatetime = NULL ,@EndDate smalldatetime = NULL AS DECLARE @SQLstr as nvarchar(4000) Set @SQLstr = 'SELECT RecID, Vendor_Num, Vendor_Name, InvoiceNum, Item_Num, (SELECT CONVERT(VARCHAR(11), RecDate,
