This article describes using an ATL wizard-generated OLE DB consumer with WTL's CWinDataExchange (DDX) to create a basic WTL database application. The sample project is a standard WTL dialog-based application that uses edit controls to display the data. It acquires data from a Microsoft Access 97/2000 database via the OLE DB for Jet 4.0 provider. The sample project demonstrates inserting, deleting, and saving rows as well as forward and reverse navigation through the rowset. It also shows basic ...

In a previous tip on Database Mirroring Automating Failover for Multiple SQL Server Databases, you've seen how you can failover all of the databases in a mirroring session if one database fails over. However, what happens if you don't have a witness server and your principal server goes, how do you make your mirror server the principal and bring all your databases online?...

There has been a lot written about SQL Server Log Shipping as well as several scripts and techniques for implementing this process. Basically Log Shipping is the process of backing up your database and restoring these backups to another server for failover. To keep the data current and to minimize risk of data loss the process involves using SQL Server transaction log backups. By using transaction log backups the size of the backups are much smaller than full backups and the restore process ca...

With the recent tips on data modeling (SQL Server 2005 Exposed = Data Modeling Tools and SQL Server Data Modeling Tools), a natural question that arose is: where are all of the underlying objects stored in SQL Server? As such, in this tip we will outline where the user defined objects in user defined databases for both SQL Server 2000 and 2005....

Handling Weeks that Overlap Years in a Date Dimension in a SQL Server Data Warehouse

Our business users want to report on some fact data aggregated by week. They define a week as beginning on Sunday and ending on Saturday without regard to the year. An example query would be how many employees were hired in each of the previous four weeks? While SQL Server has the DATEPART function which has an option to give the week number in the year for any given date, the week number resets to 1 when the year changes. Can your think of an easy way to implement this type of functionali...

We are building an Analysis Services cube and trying to understand how to create a time dimension and take advantage of the built-in time intelligence features that provide many useful calculations such as period-to-date, period-over-period growth, etc. Can you provide a detailed explanation of how it all works? Getting the time dimension configured correctly is a necessary first step in order to take advantage of the Time Intelligence features in SSAS which support the various queries that you...

Database Storage with SQL Server – Part I

Read Reviews | Write Review |  Your Rating: 

Database storage is one of the primary failure point in the database environment. Hence, making the storage architecture consistent and at the same time giving it maximum redundancy must be embedded within the design itself. When I call redundancy, I don’t specifically say implementing anything specific to RAID or SAN or other mechanisms. Redundancy must be achieved given your hardware and budget currently in hand – if it even means making just multiple backup copies at the simplest level....

MySQL Data Loading with Lookup Tables

Lookup tables contain, in general, a fixed list of data. This data doesn’t change very often in database business applications. Examples of this data could be a product list, category type, supplier list, state name, zip code, phone area code, etc. In Windows and Internet web business applications, most of these lookup tables are graphically implemented by using ComboBox, ListBox or CheckListBox read-only controls. These controls are loaded with data using two main columns, ID and Name. For exam...

Automating Database maintenance in SQL 2005 Express Edition Part I

In this series of articles, I'll demonstrate a couple of different approaches to writing a maintenance utility that mimics some of the behavior of the sqlmaint utility that is included with SQL Server 2000. SQL Server 2005 Express Edition does not include such a utility, so these articles will show how we can easily create one ourselves using either TSQL or SMO (SQL Management Objects - the successor to SQL-DMO). Rather than dive into the code, these articles will demonstrate how to use these ut...

I have over night processes on a few different SQL Servers in my environment that are backup and restore related. I have used the scripts on to check if the SQL Server Agent Jobs\Job Steps have run as well as the backup verification code. Some of the backup and restore processes I have written and others I have inherited. Some of the processes seem to be very reliable and others are not. I need a way to validate the restore processes have completed properly just like the SQL Se...

Use data cubes for efficient data warehousing in SQL Server 2000

Read Reviews | Write Review |  Your Rating: 

In the first part of this data warehousing series, I noted the structure of database storage for a data warehouse is very different from that of a conventional online transaction processing system (OLTP). The reason? OLTPs have many users and typically handle distinct data objects in any given session, whereas online analytical processing systems (OLAP) have fewer users pulling in much larger amounts of data. Therefore, from a design standpoint, it’s important to create structures that put relat...

Dimensional Databases: Building A Data Warehouse

Read Reviews | Write Review |  Your Rating: 

Building a data warehouse involves several complicated steps (some of which I described in my previous articles for InformIT). After the data warehousing architect locates all data elements necessary to support the data warehouse, it is time to build a dimensional model. As data change in transactional systems, the data warehouse needs to have a way of tracking and reflecting such changes. Populating fact and dimension tables can take considerable amount of time if the population routines aren't...

HOWTO: Access and Modify SQL Server BLOB Data by Using the ADO Stream Object (Q258038)     
Total Hits: 4425  |  Today: 0      Rating:  
Read Reviews | Write Review |  Your Rating: 

The Stream object introduced in ActiveX Data Objects (ADO) 2.5 can be used to greatly simplify the code that needs to be written to access and modify Binary Large Object (BLOB) data in a SQL Server Database. The previous versions of ADO [ 2.0, 2.1, and 2.1 SP2 ] required careful usage of the GetChunk and AppendChunk methods of the Field Object to read and write BLOB data in fixed-size chunks from and to a BLOB column. An alternative to this method now exists with the advent of ADO 2.5. This arti...
