Stairway to T-SQL DML Level 12: Using the MERGE Statement - SQLServerCentral
Prior to showing you my MERGE statement I need to create and populate my target CurrentListing table, as well as create a table that will contain the monthly current listings I get from my another source. To maintain my CurrentListing table all I need to do is create the right MATCHED and NOT MATCHED conditions to determine when to do an INSERT or UPDATE, and then include a new NOT MATCHED BY SOURCE condition to perform the DELETE operation
B) Using DDL Triggers: These triggers focus on changes to the definition of database objects as opposed to changes to the actual data.This type of trigger is useful for controlling development and production database environments. For example, if we have a foreign key constraint on a table that ensures referential integrity and a trigger that that does some validation on that same foreign key column then the trigger validation will only execute if the foreign key validation is successful
Jon Galloway - Adding simple trigger-based auditing to your SQL Server database
Could anyone post that if this works well if multiple tables are audited? jenny - Wednesday, March 11, 2009 10:44:40 PM Could anyone figure out how to make this script work for delete? This script only audit Insert and Update, not delete. Your primary tables should ALWAYS have INSERTUSERID, INSERTDATE, and MODIFIEDUSERID, MODIFIFEDDATE, this way when your audit runs, you can pull the data because you are writting it to the table..
Quick Overview: Temporary Tables in SQL Server 2005 - CodeProject
Basic overview of temporary Tables in SQL Server 2005 Table of Contents Introduction Different Types of Temporary Tables Local Temp Table Global Temp Table Creating Temporary Table in SQL Server 2005 Storage Location of Temporary Table When to Use Temporary Tables? Points to Remember Before Using Temporary Tables Alternative Approach: Table Variable When to Use Table Variable Over Temp Table Introduction SQL Server provides the concept of temporary table which helps the developer in a great way. Alternative Approach: Table Variable Alternative of Temporary table is the Table variable which can do all kinds of operations that we can perform in Temp table
Index and Statistics When retrieving data, SQL Server obviously has to make some decisions as to the best way to get to data and return it to the query requesting it. You can add nonkey columns to the leaf level of the Non-Clustered index to by-pass existing index key limits, 900 bytes and 16 key columns, and execute fully covered, indexed, queries
SQL Server Tutorials and Tips
Let's take a look at the query as shown below - --CROSS JOIN SELECT ContactName, CompanyName, City, OrderID, OrderDate, RequiredDate FROM Customers CROSS JOIN Orders Summary In this article, we have seen different types of joins you can perform in SQL Server. The query is as shown below - The output of the above query is as shown below - EXCEPT Operator We will now explore the last operator, the EXCEPT operator
The reason, I like to call it interesting is though, I have provided answers to him, I believe there should be another better alternative to this problem. However, what will be the alternative solution to this question if the clustered index is already created on the table and there was no option to modify the same
With the upcoming SQL Server 2005 extended support deadline fast approaching, they want to understand how to help you migrate to a modern, supported version of SQL Server, and how to provide support and upgrades in future. By automating the process of gathering and storing appropriate counters, you can routinely check a range of devices quickly using visual tools such as PerfMon
Finally fixed my mind to go with SP with cursor but after seeing this concatenate aggragation mechanism with STUFF in the afore mentioned example which comes in very handy and minimal code pain.

If you have to manually create the custom type, might as well create the table! I want to be able to have a piece of code that sniffs the table schema and creates a corresponding table to the best of its knowledge. Tables are carefully crafted entities in SQL, with deploy time placement consideration of choosing the proper disk, with indexing consideration at design time and with all the issues involved in properly modeling a database
so could you please share script which will automatically generate script for entire schema of a particular database(the one you mentioned at top of this thread). If there are 500 Stored Procedures and I want to generate the script for 50 stored procedures, its difficult stuff to find out and generate the script by wizard
The application submits its usual modifications against the current table, and SQL Server creates the older versions and writes those to the history table. If you need to make a change that is disallowed while system versioning is on, you need to first turn system versioning off, apply the change, and then turn it back on
scripting - In SQL Server, how do I generate a CREATE TABLE statement for a given table? - Stack Overflow
Yes, you can "right click" on the table and script the CREATE TABLE script, but: The a script will contain loads of cruft (interested in the extended properties anyone?) If you have 200+ tables in your schema, it's going to take you half a day to script the lot by hand. With this script converted into a stored procedure, and combined with a wrapper script you would have a nice automated way to dump your table design into source control etc
