Performance tuning > two tables with strings > best query to join them

Posted By:      Posted Date: September 23, 2010    Points: 0   Category :Sql Server

I have two subqueries which build a string (varchar(200)), first subquery creates 200000 records and second 50000 records, how can I write a select statement to get records from subquery first with string existing in second subquery records.

Will sorting both the sub query results be helpful? Kindly advice for best performing select statement.

MS SQL Server: Search All Tables, Columns & Rows For Data or Keyword Query

If you need to search your entire database for specific data, this query will come in handy.

So when a client needs a custom report or some sort of custom development using Great Plains, most of the time I will have to track down the data in the system by running this query and find the table(s) it is in.

Performance tuning tips for database developers

Performance tuning is not easy and there aren't any silver bullets, but you can go a surprisingly long way with a few basic guidelines.

In theory, performance tuning is done by a DBA. But in practice, the DBA is not going to have time to scrutinize every change made to a stored procedure. Learning to do basic tuning might save you from reworking code late in the game.

Below is my list of the top 15 things I believe developers should do as a matter of course to tune performance when coding. These are the low hanging fruit of SQL Server performance - they are easy to do and often have a substantial impact. Doing these won't guarantee lightening fast performance, but it won't be slow either.

Performance Tuning on DirectShow Camera Application

Windows CE 6.0 supports DirectShow® components to develop a rich camera application. A minimum requirement of the camera application is to show preview, capturing the still images which is stored as a compressed file (JPG) format, capturing/multiplexing the video with or without audio i.e. stored as a compressed file (WMV) format.

Windows CE 6.0 provides sample applications for showing preview, capturing still and video using DirectShow® components. However these sample applications doesn't cover all the aspects to develop a commercial application. A commercial camera application at least satisfies the following performance criteria.

.NET Code Tuning: Make Your Apps Fly with the New Enterprise Performance Tool


Because the common language runtime (CLR) is a black box, it's pretty hard to divine what's going on when you want to track down performance problems. Microsoft will be delivering a brand new profiler, the Enterprise Performance Tool (EPT), as part of Visual Studio 2005 Team Developer Edition that's ideal for use on a production system because it offers some very lightweight means of collecting performance data. Here John Robbins takes you on a tour.

Query Performance & Overall Design - SSAS MDX WCF

Hi All, We have a Cube which is to be queried by the Online system , using WCF service. Peroformance of the queries running on the Cube is not really very good , as we have to calculate various percentile (which are all calculated members) on the cube, this howver works well within limits of 5-6 secs for small sample size. But this goes beyond the threshold of 30 secs when the record counts increases. What we have is our SSAS Cubes , and we have WCF Service querying the Cube using ADOMD.NET. This may not be one of the best way to achieve this requirement , but we are kind of completed with development and it may not be feasible to work on another approach, what we are looking for is optimize this design and make it work with in expected time limits of 5-8 secs. Kindly let me know, if i am not clear or if you need any more info to suggest something ! Thanks a lot for your help !   Kindly

Oracle Linked serve Query performance in 2000 vs 2008 R2 64 Bit

Hi everyone We have started to migrate one of our reporting systems from Sql 2000 to Sql 2008 R2.  One of the steps has been to test the perforance of certain Oracle linked server queries between each server.  We are finding on average 3 fold better perforance stats (in terms of query completion time) on the old server.  This should obviously not be the case.  The new server has signifantly more CPU/Memory/IO resources to play with, and it is 64 bit (not to mention its new!).  Here's what I got so far: Old server: SQL 2000 on W2000 both fully patched.  Old Dell Dual core with 3 GB of Ram running on two soft IDE Mirrored drives (yes I know... it sucks).  It connecting via the MS OLE DB provider for Oracle (9i client) New server: ESX VMware Server with 2 CPU's assigned, 8 GB of ram connected to large HP SAN.  CPU, ram and IO's have all been ruled out as the problem.  We've tried varying network cards with different results so we havent ruled that out yet.  Its connecting via the Oracle provider for OLE DB (11G 64 bit client) The linked server is an Oracle 9i fully patched server.  All three are on the same network backbone. Running a simple select * query on both servers returns the same number of rows (~76 000) .  It takes ~1:20 on the new server and ~0:20 on the old server. In looking at the wait stati

Full text performance of a certain query

I am doing a full text query on a very simple table and when I include the search term "y5v" in the conditions it slows the query down like 8 to 1. The table is defined as: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[tblTextSrchData]( [intItemId] [int] NOT NULL, [srchTxt] [varchar](max) NOT NULL, CONSTRAINT [PK_tblTextSrchData] PRIMARY KEY CLUSTERED ( [intItemId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] Here is the query: SELECT II.intItemID, KEY_TBL.[RANK] as Score FROM tblItems II INNER JOIN CONTAINSTABLE(dbo.tblTextSrchData,srchTxt, '("capacitor" OR FORMSOF(INFLECTIONAL, "capacitor") OR "capacitor*") AND ("active" OR FORMSOF(INFLECTIONAL, "active") OR "active*") AND ("y5v" OR FORMSOF(INFLECTIONAL, "y5v") OR "y5v*")') KEY_TBL ON KEY_TBL.[KEY] = II.intItemID If I take any of the additional search terms out it improves performance.  If I remove the yv5 search term the results are returned in less than a second. What seems to be the problem is for some reason when I add yv5 it starts doing these sorts after the full text matching.  These sorts take most of the time.  I'm not sure

any alternative for join tables?

 Hi guys, is  there any alternative for joining tables in ado.net? The problem is i have 2 tables: Transaction pkTransactionID TransactionDate FKTransactionCategory : refers to PKCAtegoryID   Category PKCAtegoryID CategoryName   I need to show a joined information from 2 tables in a gridview and be able to update data in tables. I can join them using linq to entity and show them in gridview. But i need to handle update and insert by myself then. Is there any way to make mapping so i can handle the data in those 2 tables as one table and bind it to bindingsource? Thanks in advance.
