sql-server-2005

问题 I'm new here, and relatively new to stored procedures, so please bear with me! I've checked related questions on here and can't find anything that works in this instance. I am trying to build a stored procedure (MS SQL Server 2005) that takes a number of passed in values and in effect dynamically builds up the SQL as you would with inline SQL. This is where I've come unstuck. We have (somewhat simplified for clarity): @searchf1 varchar(100), -- search filter 1 @searchr1 varchar(100), --

问题 I need to write a generic procedure that set value for one column or no of a columns in a table depending on parameters. Any idea how to do it. 回答1: I would guess you want something like: CREATE PROC UpdateProc @RowID UNIQUEIDENTIFIER, @Parameter1 NVARCHAR(50) NULL, @Parameter2 INT NULL AS SET NOCOUNT ON GO IF @Parameter1 IS NOT NULL BEGIN UPDATE MyTable SET Column1 = @Parameter1 WHERE ID = @RowID END IF @Parameter2 IS NOT NULL BEGIN UPDATE MyTable SET Column2 = @Parameter2 WHERE ID = @RowID

问题 Can someone tell me why the following SQL Server queries is deadlocking and what is the solution to fixing it? <deadlock-list> <deadlock victim="process88b5b8"> <process-list> <process id="process88b5b8" taskpriority="0" logused="76132" waitresource="RID: 32:1:151867:174" waittime="5093" ownerId="65554098" transactionguid="0xedf3314c05f1124cbe8d480cd092e03e" transactionname="DTCXact" lasttranstarted="2011-09-02T19:00:29.690" XDES="0x1029e040" lockMode="S" schedulerid="1" kpid="5108" status=

问题 I'm in a very, very tight situation here. I have an SQL query running on SQL Server 2005: SELECT col1,col2,col3 FROM myTable Which of course gives: col1 | col2 | col3 ------------------ 1 | a | i 2 | b | ii etc I need to, if possible, add a COUNT query so that it will return the number of records returned. I cannot use GROUP BY or an aggregate function (It's a very edge case on some very inflexible software). Ideally, something like this: SELECT col1,col2,col3,COUNT(NumberOfRows) as NumRows

问题 I'm working with a Customer Relationship Management application. I have two tables: tbl_Inquiry_master for storing inquiry question details raised by end users, and tbl_Inquiry_History for storing inquiry answer details. However this shows knowledge to store one question store to table tbl_Inquiry_master and answers that are given by staff to that inquiry stored in table tbl_Inquiry_History . For more information I represent table tbl_Inquiry_master schema: Column Name Data Type _____________

问题 This is part of a bigger selection, but I have stripped it down to the essential question : Compare this two SQL queries - the first works with a constant, the second with a variable, both have the same value (lets say 180). The one with the constant displays result immediately (e.g. within milliseconds), the one with the variable takes a few seconds to yield the same result. Where is the catch ? Query 1: SELECT * FROM table WHERE field > 180 Query 2: DECLARE @V INT SET @v = 180 SELECT * FROM

问题 I have the following stored procedure which takes a user ID, a starting date, an end date, and a list of codes in a comma-delimited list, and it returns all activity records between those two dates which match one of the codes in the list. ALTER PROCEDURE [dbo].[ActivitiesSummary] @UserID varchar(30), @StartDate datetime, @EndDate datetime, @Codes varchar(100) AS BEGIN SET NOCOUNT ON; SELECT act.SectionID, act.UnitID, act.ActivityCode FROM dbo.Activities act INNER JOIN ConvertCodeListToTbl(

问题 I know you can do something like: select count(*) as Qty from sys.databases where name like '%mydatabase%' but how could you do something like: select count(*) as Qty from linkedServer.sys.databases where name like '%mydatabases%' I guess I could put a stored procedure on the linked server and execute the first select, but is there a way to query a linked server for what databases it holds? 回答1: Assuming your linked server login has read permissions on the master.sys.databases table, you can

问题 I am running a dynamic sql command with sp_msforeachdb for each database. However the command bombs for a certain database. How is '?' used to display the database name when the error happens? I tried using it in a Catch statement but my syntax is wrong. 回答1: Just use DB_NAME() EXEC sp_msforeachdb 'USE ? SELECT DB_NAME() ...do stuff' 回答2: It worked to me: exec sp_MSforeachdb 'select *, print ''?'' from TABLE' 回答3: Depending on the script, you get for all db's the ouput "master" with DB_NAME()

问题 I needed to write function with table parameter. an example: CREATE FUNCTION getParentByBrandList ( @_BrandList TABLE( BR_ID INT, BR_Name NVARCHAR(150), BR_ParentBrandID INT, BR_MasterBrandID INT, BR_Role INT, BR_State INT, BR_OwnerID INT, BR_OwnerIP NVARCHAR(50), BR_CreateDate DATETIME, BR_UpdaterID INT, BR_UpdaterIP NVARCHAR(50), BR_UpdateDate DATETIME ) ) How can I do? Thanx 回答1: Beginning from SQL Server 2008 you can use table valued parameters: CREATE TYPE [dbo].[TableType] AS TABLE( [ID
