How Do I Increase My Processor Speed

Implementation of a validity test with SQL Server Integration Services

Hi everyone! If

SSIS has great advantages in terms of debugging by design, it nevertheless remains largely a tool for improvement on a number of points.

The first of these is probably the weakness of function libraries accessible in the data conversion tasks. Indeed, the conventional tests to identify the correct classification of the imported data in a Data Flow (ISDATE, ISNUMERIC, ...) can not be made otherwise than by Script Component task ... A long and often tedious task to develop, particularly if the number of fields to be tested is especially important. If
to this important gap solution to redevelop a specific component for SSIS comes immediately to mind, the reality of deployment on the client catches up to us inexorably. Indeed, it is necessary to deploy the said component impacted on all servers that can quickly be tricky ...

So I come here to propose an alternative solution, although not very satisfactory for which I am a perfectionist: the use of temporary tables !
While SSIS does not have adequate functions, the Transact-SQL can come to our rescue!
should therefore integrate the data source into a temporary table independent of data format - eg VARCHAR fields - then make the changes and integrity checks as part of a stored procedure ...

If this remains lackluster, it is really the only viable solution as SQL Server Integration Services will not offer a library of components and functions satifaisante ...

Moving System databases SQL Server 2005 ...

Hello everyone!

Here is a post that should not leave indifferent those who carried out the laborious movement of all databases of a SQL instance, in particular the bases system!

While the movement of these bases is well documented in MSDN, it is nevertheless extremely tedious to undertake such an operation ... However, there
the significant effort that Microsoft has agreed to streamline the movement between the SQL Server 2000 and SQL Server 2005.

For the record, you will find here documentation for moving files from system databases in SQL Server 2000 and SQL Server 7.
Under SQL Server 2005, only moving databases and Master mssqlsystemresource, new database that did not exist in SQL Server 2000, requires special treatment.

I therefore propose here a customizable script that should delight young and old who want to move their databases SQL Server 2005 system with one click!

To exploit this code, save the file in a Visual Basic Script (eg c: \\ movedb.vbs) and run it!
