For now, we will code this directly and later turn it into a function: We must tell PowerShell the name of the file and where the file is located for it to do this. PowerShell will automatically create our staging table using the above assumptions by reading from the file we want. PowerShell Code to Automatically Import Data Remember, you're paying for it, so make sure that it's what you want. In a world of competitive data providers, most small startup shops have a large supply of who they want to work with if they don't like a specific company's data. These are important to note because for every exception to the rule, an exception must be noted in code.

The name of the file will be the name of the staging table.

New line characters demarcate new rows.

The column names are listed in the first line of the file.

The flat files columns are delimited by a character (in this example, a comma).

We will make some assumptions about these files and if any of these assumptions are incorrect, the below code must be changed to reflect it: Because we are focusing on extraction, we will import these data into a staging table, accepting everything in the file. I've provided three different files - savings.txt, inflationdata.csv and spy.csv as examples for this tip, but will refer to savings.txt for the written example (screenshots of the results are seen for all three).īefore importing flat file data into a table, a table needs to exist for these data.

If this is not the case, you will need to spend time re-naming the files you receive. For the sake of this example, we'll assume that the data provider sends only flat file data and that these files are named in an appropriate manner for their data (meaning, if it's stock data, the data file is "stock.txt"). Due to our limited budget and time, how can we automate this? Solutionīefore we begin, if your data provider possesses an API, it may be simpler to grab live data. A data provider sends us flat file data and we extract, analyze and report on these data.

We're looking to minimize ETL costs by importing as much data as possible using a automated system. By: Tim Smith | Updated: | Comments (39) | Related: More > Import and Export
