I have a test today with an employer who is testing me on MS Access, MS Excel, and MS SQL.
Does anyone know where I can learn about SQL, the main points, to help me with the test.
I need like a site that would breifly go over Triggers, Stored Procedures, Joins, Withs, Unions, ect...
Thanks
I've done some basic database stuff with Access and ASP, but I have a client who has told me that he is in over his head and wants me to try getting his "mini CMS" site to work. He told me that he set everything up in Dreamweaver using ASP and "MSSQL"
I have never used what he calls: "MSSQL" before. Do I need software to create an "MSSQL" database? or is it all coded?
Also, one other question. The whole purpose of this site is to have Admin users log in to a page where they can edit the content of a page and upload it. If there is a large block of text, does it all reside in a field in the database, or would it be a link to a text file? kind of like linking to an image since images don't actually reside in the database.
Thanks for any direction you might have

Hello,
This is my first project with SSIS and I'm having some problems migrating our current data import to it. Generally: right now we're pulling hourly data (which has a timestamp on it) in from a customer's db(which can't be modified, and is big and growing quickly) into our db. To do this we have been using a field to keep track of the last data download time (in our db) and then using that then when querying the customer's db to reduce the number of rows returned.
Will a similar system work in SSIS? I'm having trouble pulling the last download date out of the "target" database and using it in the query on the customer's db. Any advice on what I should be looking into to do this and am I headed in the right direction or just not thinking about this in a SSIS way?
How powerful/common are variables in SSIS and should I be trying to use them here?
Thanks,
Jeff
Many people know the importance of creating indexes on SQL Server database tables. Indexes greatly improve the performance of a database. However, while many people create indexes on their SQL Server tables, many people don't maintain them properly to ensure queries run efficiently as possible.

Simplify application development
Language Integrated Query (LINQ)
Enable developers to issue queries against data, using a managed programming language, such as C# or VB.NET, instead of SQL statements. Enable seamless, strongly typed, set-oriented queries written in .NET languages to run against ADO.NET (LINQ to SQL), ADO.NET DataSets (LINQ to DataSets), the ADO.NET Entity Framework (LINQ to Entities), and to the Entity Data Service Mapping provider. Use the new LINQ to SQL provider that enables developers to use LINQ directly on SQL Server 2008 tables and columns.
ADO.NET Object Services
The Object Services layer of ADO.NET enables the materialization, change tracking, and persistence of data as CLR objects. Developers using the ADO.NET framework can program against a database, using CLR objects that are managed by ADO.NET. SQL Server 2008 introduces more efficient, optimized support that improves performance and simplifies development.

Store any information
DATE/TIME
SQL Server 2008 introduces new date and time data types:
DATE€”A date-only type
TIME€”A time-only type
DATETIMEOFFSET€”A time-zone-aware datetime type
DATETIME2€”A datetime type with larger fractional seconds and year range than the existing DATETIME type
The new data types enable applications to have separate data and time types while providing large data ranges or user defined precision for time values.
HIERARCHY ID
Enable database applications to model tree structures in a more efficient way than currently possible. New system type HierarchyId can store values that represent nodes in a hierarchy tree. This new type will be implemented as a CLR UDT, and will expose several efficient and useful built-in methods for creating and operating on hierarchy nodes with a flexible programming model.
FILESTREAM Data
Allow large binary data to be stored directly in an NTFS file system, while preserving an integral part of the database and maintaining transactional consistency. Enable the scale-out of large binary data traditionally managed by the database to be stored outside the database on more cost-effective storage without compromise.
Integrated Full Text Search
Integrated Full Text Search makes the transition between Text Search and relational data seamless, while enabling users to use the Text Indexes to perform high-speed text searches on large text columns.
Sparse Columns
NULL data consumes no physical space, providing a highly efficient way of managing empty data in a database. For example, Sparse Columns allows object models that typically have numerous null values to be stored in a SQL Server 2005 database without experiencing large space costs.
Large User-Defined Types
SQL Server 2008 eliminates the 8-KB limit for User-Defined Types (UDTs), allowing users to dramatically expand the size of their UDTs.
Spatial Data Types
Build spatial capabilities into your applications by using the support for spatial data.
Implement Round Earth solutions with the geography data type. Use latitude and longitude coordinates to define areas on the Earth's surface.

Integrate any data
Backup Compression
Keeping disk-based backups online is expensive and time-consuming. With SQL Server 2008 backup compression, less storage is required to keep backups online, and backups run significantly faster since less disk I/O is required.
Partitioned Table Parallelism
Partitions enable organizations to manage large growing tables more effectively by transparently breaking them into manageable blocks of data. SQL Server 2008 builds on the advances of partitioning in SQL Server 2005 by improving the performance on large partitioned tables.
Star Join Query Optimizations
SQL Server 2008 provides improved query performance for common data warehouse scenarios. Star Join Query optimizations reduce query response time by recognizing data warehouse join patterns.
Grouping Sets
Grouping Sets is an extension to the GROUP BY clause that lets users define multiple groupings in the same query. Grouping Sets produces a single result set that is equivalent to a UNION ALL of differently grouped rows, making aggregation querying and reporting easier and faster.
Change Data Capture
With Change Data Capture, changes are captured and placed in change tables. It captures complete content of changes, maintains cross-table consistency, and even works across schema changes. This enables organizations to integrate the latest information into the data warehouse.
MERGE SQL Statement
With the introduction of the MERGE SQL Statement, developers can more effectively handle common data warehousing scenarios, like checking whether a row exists, and then executing an insert or update.
SQL Server Integration Services (SSIS) Pipeline Improvements
Data Integration packages can now scale more effectively, making use of available resources and managing the largest enterprise-scale workloads. The new design improves the scalability of runtime into multiple processors.
SQL Server Integration Services (SSIS) Persistent Lookups
