问题 I have a problem similar to the on in this weeks podcast. We have a Java application using hibernate with Sql Server 2005. Hibernate is generating a Query for us that is taking nearly 20 minutes to complete. If we take the same query using show_sql and replace the questions marks with constant value the answer is returned immediately. I think we need option(recompile), but I can't figure out how to do that with HQL. Please help! 回答1: From the description of your problem, it sounds like you're

问题 OK. I'm doing an update on a single row in a table. All fields will be overwritten with new data except for the primary key. However, not all values will change b/c of the update. For example, if my table is as follows: TABLE (id int ident, foo varchar(50), bar varchar(50)) The initial value is: id foo bar ----------------- 1 hi there I then execute UPDATE tbl SET foo = 'hi', bar = 'something else' WHERE id = 1 What I want to know is what column has had its value changed and what was its

问题 I have a 1 TB, 600m row, table which has a misguided choice of indexed columns, specifically a clustered index on the primary key column which is never used in a select query. I want to remove the clustered index from this row and create it on a number of other rows. Table is currently like this: colA (PK, nvarchar(3)) [clustered index pt b] colB (PK, bigint) [clustered index pt a] colC (DateTime) [non-clustered index] colD (Money) [non-clustered index] colE (bit) [no index] colF (bit) [no

问题 How to deploy Sql server reports on productions boxes? Locally it's not a problem, I just specify the url and then right click on project and say deploy which deploy on my local server. But it's not gonna be the case for the production server 回答1: I recommend you create rs scripts that can be executed on production server. Take a look at Reporting Services Scripter. It's creates deployment scripts based on your current installation. http://www.sqldbatips.com/showarticle.asp?ID=62 回答2: Either:

问题 I want to join three tables and to calculate the Sum(Quantity) of the Table A. I tried something and I get the desired output. But still I have confusion based on aggregate function and Group By clause. While calculating the sum value by joining two or more tables, what are the columns we need to mention in the Group By clause and why do we need to give those columns? For Example: Here is my table and the desired query. TableA: ItemID, JobOrderID, CustomerID, DivisionID, Quantity TableB:

问题 I'm currently having following error message when executing a .sql file with about 26MB on SQL Server 2005: Msg 701, Level 17, State 123 There is insufficient system memory to run this query. I'm working with 4GB RAM, 64Bit Windows 7 Ultimate, Core2Duo T6400(2GHz)... Is there a way to execute it without receiving this message (maybe force SQL Server to use swap file?) or a way to execute it in parts (like 100 queries a time)... The file is basically a CREATE TABLE followed by thousads of

问题 I need to add a NOT NULL column to an existing (populated) table that will be a foreign key to another table. This brings about two problems: When you add the column, its value cannot be null - using a default is not an option (unless it is removed later on) because the database logic is used in the server side validation when a user enters a new record i.e. when the application tries to add a record with this field having a null value, the database throws an error that the application

问题 I plan to use MS SQL Server 2005 application roles in my application. I will start the role by executing the sp_setapprole and finish by executing the sp_unsetapprole SPs. The application is implemented in ASP.NET. I've read that "connection pooling doesn't work" with application pooling and there is no way to react on connection "disconnect event" (execute sp_unsetapprole just before disconnection). I plan to call sp_setapprole at the start of all my SPs and call sp_unsetapprole at the end

问题 I have a string '2009-06-24 09:52:43.000', which I need to insert to a DateTime column of a table. But I don't care about the time, just want to insert it as 2009-06-24 00:00:00.000 How can I do that in T-SQL? 回答1: For SQL Server 2005 and below: CONVERT(varchar(8), @ParamDate, 112) -- Supported way CAST(FLOOR(CAST(@ParamDate AS float)) AS DATETIME) -- Unsupported way For SQL Server 2008 and above: CAST(@ParamDate AS DATE) 回答2: declare @originalDate datetime select @originalDate = '2009-06-24
