When creating SSIS packages it’s a common requirement to be able to archive the processed files. Here’s VB.Net code snippet, with a quick walkthrough, that does exactly that. The script uses two variables, inFiles and archiveFiles. The variable inFiles contains the folder we want to move files from, and archiveFiles is the destination. Configure your [...]
A few days ago I was working with a client that was providing an export of data from Oracle. The file being produced was choking my SSIS package due to various formatting issues. After working with the client and getting a file that looked good to the naked eye I discovered that a large amount [...]
Today I needed to order some data by specific column value and I recalled the really handy FIELD function in MySQL. Here’s a demo of this feature in MySQL ?View Code MYSQL# Test table CREATE TABLE City ( Id INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY, City VARCHAR(50) ); # Insert some test data INSERT [...]
So exactly what is a computed column? MSDN has this to say A computed column is computed from an expression that can use other columns in the same table. The expression can be a noncomputed column name, constant, function, and any combination of these connected by one or more operators. The expression cannot be a [...]
I’ve blogged before about the usefulness of Powershell for data tasks. A few weeks ago I had a requirement at work for merging csv files and recently I needed to split a single csv file into several files. While this is easy to do using SSIS and a bit of T-SQL it is a little [...]
Progress bars can be a nice visual indicator as to how a far a task is into its workload. Windows Powershell provides us with the ability to create these within the console fairly easily. This simple code will demonstrate the basics of the Write-Progress cmdlet, which allows us to deploy progress bars in our scripts. [...]
With Powershell and SMO you can easily discover SQL Server instances running on your network in just a few lines of code. ?View Code POWERSHELL[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | Out-Null; $smoObj = [Microsoft.SqlServer.Management.Smo.SmoApplication]; # This gets the sql servers available $sql = $smoObj::EnumAvailableSqlServers($false) foreach($sqlserver in $sql) { Write-Host -ForegroundColor Green "Discovered sql server: " $sqlserver.Name; } [...]
Powershell is really useful for documenting and managing your servers but it’s also a pretty good tool for working with data. I’ve been using it to merge csv files, with an identical structure, into a single file. Now this is pretty easy, if rather tedious, to do using SQL Server Import / Export functionality or [...]
Jorge Segarra (Blog | Twitter) posed the question System Documentation: What’s your method?. In my experience documentation has either been nonexistent, out of date or even worse, plain wrong. These situations often get blamed on lack of time dedicated to documentation tasks. Therefore I’ve always aimed at making documentation easy or even fun. I’ve blogged [...]
In a previous post I demonstrated how a little bit of VBA code can be used to build some basic user interfaces to deliver data. Continuing on with this the examples here will show how to build some basic user interfaces; Combo box (or drop down list) and a Multi-Select List. Like the previous examples [...]
