Introduction to SQL Compare. SQL Compare is the industry standard for comparing and deploying SQL Server database schemas quickly and accurately. 71% of the Fortune 100 use SQL Compare to compare SQL Server databases – because it's relentlessly tested, easy to use, creates flawless deployment scripts, and saves time. “The core component of Microsoft SQL Server is the SQL Server Database Engine, which controls data storage, processing and security. It includes a relational engine that processes commands and queries, and a storage engine that manages database files, tables, pages, indexes, data buffers and transactions. For example, comparing Development and Production databases against each other, or comparing a database against a SQL Server Database project. Running SQL Server queries to compare data and schema is a daily job of many IT professionals. Do you create linked servers, clone databases, copy data to a spreadsheet or a file to compare it later?

DON'T be tempted to do things like this: Select * from [User] U where convert(varchar(10),U.DateCreated, 120) = '2014-02-07' This is a better way: Select * from [User] U where U.DateCreated > Crack xlstat 2017 torrent. = '2014-02-07' and U.DateCreated = '20120101' AND col. If you are on SQL Server 2008 or later you can use the date datatype: SELECT * FROM [User] U WHERE CAST(U.DateCreated as DATE) = '2014-02-07' It should be noted that if date column is indexed then this will still utilise the index and is SARGable. This is a special case for dates and datetimes. You can see that SQL Server actually turns this into a > and =.
Unfortunately SQL defines between with equals at both ends (>= and = with ='2014-02-07' and U.DateCreated. First, I will say that 'Oo shiny gold!' Favoritism and a general lack of manners are every once in a while a problem here. Second, in this particular instance, @marc_s is absolutely right. It's a good habit not to make assumptions about marginal scenarios about how the OP might want to do string operations on the date, when the cost of that assumption is far too great regarding performance, readability, maintainability, and general best practice. This IS a place to exchange experience. But to do that, it needs to be able to point out bad or unrecommended experiences and methodologies as well.

Sql Data Compare
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? EDIT Okay, thought I'd clarify this question a little.
The table I need to synchronize is a simple look-up table. The data is very simple and straightforward.
Here's an idea of what TABLE A might look like: IdFoo Activity IsFoo 1 Foo 1 2 Bar 0 Here's an idea of what TABLE B might look like: IdFoo Activity IsFoo 1 Foo 1 2 Bar 1 Basically, all I want to do is update that BIT column ( IsFoo) in TABLE B to match the corresponding value in TABLE A for the same IdFoo. Keep in mind: • TABLE A is on my local machine • TABLE B is on the live server Obviously I have a (reliable) backup of TABLE B on my local machine which i need to script against, then run the script on the live server. The table also has referential integrity (other columns I didn't show). Which means I can't just delete everything in TABLE B and do an insert from TABLE A. This script will be a once off. So no need to do things like linked server, replication, etc. Appreciate the answers though guys.
=) EDIT: Ok - so I've gone with Oleg's answer (VS2010 Data Compare). Quick, easy, and works a charm. Not to say the other answers are incorrect. I appreciate all the answers! In very simple cases you will be able to define in your local SQL Server a new Linked Server (see in Microsoft SQL Server Management Studio under 'Server Objects' / 'Linked Server') and use INNER JOIN and OUTER JOIN to find out differences between A and B tables.
