• More memory usage for IIS 6 asp.net 2.0 on webserver 2003

  - by Alan King

  Running a webserver 2003 SP2 (x86) with IIS 6 and asp.net 2. The box is running mostly dynamic asp pages connecting to a sql 2008 server. At any given time there is over 1 gig of memory available out of the 2 gig in the box. It seems like there would be a way for it to make better use of the free memory. It is using a default machine.config file and default http.sys. I would like to maximize incoming internet connections and database connections. Is there something I can do to make better use of the available memory?

• Implications of Fulltext Search over many columns

  - by Alex

  Hello, I have a really wide table which includes separate columns for billing address, shipping address, primary address, names, aliases etc. (I can't normalize this table further, and that's not the question here anyways). I'm implementing SQL Server fulltext search, and I'm wondering whether I should limit the search ability to just the primary fields (primary address and names for example), or if I can extend the search ability across all columns without occurring too much of a performance or memory penalty. I've done some basic testing with 10,000 sample rows and it's quite fast but I don't have much experience with fulltext indexing, especially its dictionary internals, so I don't know if the index is going to grow over time, or if there is anything else to consider. Thoughts?

• Store time of the day in SQL

  - by nute

  How would you store a time or time range in SQL? It won't be a datetime because it will just be let's say 4:30PM (not, January 3rd, 4:30pm). Those would be weekly, or daily meetings. The type of queries that I need are of course be for display, but also later will include complex queries such as avoiding conflicts in schedule. I'd rather pick the best datatype for that now. I'm using MS SQL Server Express 2005. Thanks! Nathan

• Finding efficient overlapped entries in a SQL table

  - by Laoneo

  What is the most efficient way to find all entries which do overlap with others in the same table? Every entry has a start and end date. For example I have the following database setup: CREATE TABLE DEMO ( DEMO_ID int IDENTITY , START date NOT NULL , END date NOT NULL }; INSERT INTO DEMO (DEMO_ID, START, END) VALUES (1, '20100201', '20100205'); INSERT INTO DEMO (DEMO_ID, START, END) VALUES (2, '20100202', '20100204'); INSERT INTO DEMO (DEMO_ID, START, END) VALUES (3, '20100204', '20100208'); INSERT INTO DEMO (DEMO_ID, START, END) VALUES (4, '20100206', '20100211'); My query looks as follow: SELECT DISTINCT * FROM DEMO A, DEMO B WHERE A.DEMO_ID != B.DEMO_ID AND A.START < B.END AND B.START < A.END The problem is when my demo table has for example 20'000 rows the query takes too long. My environment is MS SQL Server 2008. Thanks for any more efficient solution

• ANSI PADDING defaults question

  - by IanC

  I have SQL Server 2008 SP2. I noticed that DBs by default have Properties | Options | Miscellaneous | ANSI Padding Enabled = FALSE. However, this BOL article warns against setting it to off (no reason given). Further, this article states this feature is going to be deprecated. I have two questions: What is the "problem" with having it off for current work (future deprecation aside)? Why is it defaulted to FALSE when BOL says the default is ON, and should this setting therefore be changed?

• SELECT with a Replace()

  - by andyjohnson

  I have a table of names and addresses, which includes a postcode column. I want to strip the spaces from the postcodes and select any that match a particular pattern. I'm trying this (simplified a bit) in T-SQL on SQL Server 2005: SELECT Replace(Postcode, ' ', '') AS P FROM Contacts WHERE P LIKE 'NW101%' But I get the following error; Msg 207, Level 16, State 1, Line 3 Invalid column name 'P'. If I remove the WHERE clause I get a list of postcodes without spaces, which is what I want to search. How should I approach this? What am I doing wrong?

• "lock request time out period exceeded" Error When Trying to See DB Hierarchies

  - by Lloyd Banks

  I have a DB that I can run basic queries (albeit much slower than normal) off of. When I try to see the hierarchy trees for tables, views, or procedures in SSMS Object Explorer, I get the "lock request time out period exceeded". My Report Server reports that run off of objects in this DB are no longer completing. Jobs associated with procedures stored on this DB also do not run. I tried using sp_who2 to find and kill all connections on the DB. This has not solved the problem. What is going on here? How can I resolve this?

• How do you manage your sqlserver database projects for new builds and migrations?

  - by Rory

  How do you manage your sql server database build/deploy/migrate for visual studio projects? We have a product that includes a reasonable database part (~100 tables, ~500 procs/functions/views), so we need to be able to deploy new databases of the current version as well as upgrade older databases up to the current version. Currently we maintain separate scripts for creation of new databases and migration between versions. Clearly not ideal, but how is anyone else dealing with this? This is complicated for us by having many customers who each have their own db instance, rather than say just having dev/test/live instances on our own web servers, but the processes around managing dev/test/live for others must be similar.

• Hashbytes comparison in stored proceduring not matching record

  - by Michael Itzoe

  The password field in my user table (SQL Server 2008) is encrypted using HASHBYTES on insertion. I have a stored procedure with parameters for the username and plain-text password which does a SELECT using that username and the password sent through HASHBYTES, then returns the user record if it finds a match. The SP is always returning an empty recordset, but if I copy and paste just the SELECT from the SP to a new query window, it returns the matched record. There're no other statements in the SP. I'm missing something here; what is it?

• Float as DateTime

  - by lp1

  SQL Server 2008 I almost have, I think, what I'm looking to do. I'm just trying to fine tune the result. I have a table that stores timestamps of all transactions that occur on the system. I'm writing a query to give an average transaction time. This is what I have so far: With TransTime AS ( select endtime-starttime AS Totaltime from transactiontime where starttime > '2010-05-12' and endtime < '2010-05-13') Select CAST(AVG(CAST(TotalTime As Float))As Datetime) from TransTime I'm getting the following result: 1900-01-01 00:00:00.007 I can't figure out how to strip the date off and just display the time, 00:00:00:007. Any help would be appreciated. Thank you.

• Trying to programmatically add a SQL Alias to the registry (just need help with parameters)

  - by nycgags

  Normally when we spin up a new instance we need to add an alias on one of our boxes so we can easily connect to it through SSMS using SQL Server Configuration Manager. I have written a batch file which adds the appropriate entry into the registry (it is actually two batch files, one for 32 bit and one for 64 bit). I am not sure how to get this to run with parameters though. I know %1 and %2 would be for the first two parameters, but when I run this, in the registry it actually puts %1 and %2 as the value pair. if you hardcode hostname and IP Address in place of %1 and %2 the batch file works as expected: REGEDIT4 ; @ECHO OFF ; CLS ; REGEDIT.EXE /S "%~f0" ; EXIT [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\Client\ConnectTo] "%1"="DBMSSOCN,%2,1433"

• SQL Script To Generate a Database Dictionary **With Linked Fields**

  - by Albert

  I would like to generate a Data Dictionary for a SQL Server 2008 database that has one row for each field, and the following columns: table_name field_name data_type link_table (for when the field in question is a foreign key) link_field (for when the field in question is a foreign key) I can get the first 3 columns with something like the SQL script below...but I don't know how to get the last two columns of foreign key information. INFORMATION_SCHEMA.TABLE_CONSTRAINTS gets close, but doesn't have the data I'm looking for. Can someone help with this point? SELECT TABLE_NAME,COLUMN_NAME,DATA_TYPE FROM INFORMATION_SCHEMA.COLUMNS Secondarily if anyone has any suggestions on additional fields which would be helpful please post.

• How to generate multiple Alter Scripts in SSMS

  - by dannyRods

  I'm using sql server management studio 2008 to try and generate an alter script for each of my stored procedures in order to save the scripts for each revision. I can easily generate an alter script for each individual procedure, but I'm not trying to go through a hundred stored procedures manually. I know that SSMS has an automated generate scripts function under task, but the only options are create, drop and create, and drop. I cant seem to figure out how to enable alter. I've already searched through many SO articles, as well as a little digging in msdn, and I've come up with nothing. I'm hoping that the fine people of stackoverflow will be up to the challenge. Thanks in advance

• T-SQL stored procedure to return google style "suggested" search results

  - by stephen776

  Ok, using SQL Server 2008. On my web page I have a textbox with jQuery-UI AutoComplete hooked up. Now I need a stored procedure to search across all columns of a single table(or multiple joined tables I suppose) for a search string coming from the textbox/autocomplete AJAX call, and return "suggested" search strings. I am using the AdventureWorks db for testing(Products table) So for example, the product table has columns for product name and product number(among others) and I want to return suggested search strings based on user input where they may enter a product name and/or a product number. I have it working across a single column which was simple. Any ideas?

• T-SQL - Is there a (free) way to compare data in two tables?

  - by RPM1984

  Okay so i have table a and table b. (SQL Server 2008) Both tables have the exact same schema. For the purposes of this question, consider table a = my local dev table, table b = the live table. I need to create a SQL script (containing UPDATE/DELETE/INSERT statements) that will update table b to be the same as table a. This script will then be deployed to the live database. Any free tools out there that can do this, or better yet a way i can do it myself? I'm thinking i probably need to do some type of a join on all the fields in the tables, then generate dynamic sql based on that. Anyone have any ideas?

• What causes Apache Environment Variable set using mod_rewrite to have "redirect_" appended to name?

  - by trowel

  I am trying to set Apache environment variables (for use in PHP) with the [E=VAR:VAL] flag on RewriteRule rules in an .htaccess file. I have already discovered the variables are accessed in PHP as server variables $_SERVER rather than $_ENV (which makes a certain amount of sense). However, my problem is for some rules the [E=VAR:VAL] flag works as expected and I end up with a variable $_SERVER['VAR'] but for other rules I end with a variable $_SERVER['REDIRECT_VAR'] or $_SERVER['REDIRECT_REDIRECT_VAR'], etc A. What causes an Environment Variable set in Apache using the [E=VAR:VAL] flag to get renamed by having "REDIRECT_" appended to the front of the variable name? B. What can I do to make sure I end up with an Environment Variable with an unchanged name so I can access it in PHP as $SERVER['VAR'] without having to resort to checking for variations of the variable name having one of more instances of "REDIRECT" appended to the front of it?

• Database design: one huge table or separate tables?

  - by littlegreen

  Currently I am designing a database for use in our company. We are using SQL Server 2008. The database will hold data gathered from several customers. The goal of the database is to acquire aggregate benchmark numbers over several customers. Recently, I have become worried with the fact that one table in particular will be getting very big. Each customer has approximately 20.000.000 rows of data, and there will soon be 30 customers in the database (if not more). A lot of queries will be done on this table. I am already noticing performance issues and users being temporarily locked out. My question, will we be able to handle this table in the future, or is it better to split this table up into smaller tables for each customer?
