</p>
<p>Just a quick recipe I developed a few years ago that I thought
might be useful to others. Basically it takes as input a
data file with comma separated values (CSV) and translates
this into a series of SQL "INSERT" statements allowing you
to then feed this into MySQL, SQLite, or any other database.</p>
<p>Example Usage:</p>
<p>$ cat cars.csv
Year,Make,Model,Length
1997,Ford,E350,2.34
2000,Mercury,Cougar,2.38</p>
<p>$ sqlite3 cars.db "CREATE TABLE cars (Year, Make, Model, Length)"</p>
<p>$ ./csv2sql.py cars.csv | sqlite3 cars.db </p>
<p>$ sqlite3 cars.db "SELECT * FROM cars"
1997|Ford|E350|2.34
2000|Mercury|Cougar|2.38</p>
<p>Enjoy! Feedback welcome!</p>

</p>
<p>This recipe shows how to read data from a CSV file with a D program and write that data to a PDF file with a Python program - all in a single command-line invocation (after writing the individual programs, of course).</p>
<p>It requires the xtopdf toolkit, which you can get from:</p>
<p><a href="https://bitbucket.org/vasudevram/xtopdf" rel="nofollow">https://bitbucket.org/vasudevram/xtopdf</a></p>
<p>Instructions for installing xtopdf:</p>

<p>xtopdf in turn requires the open source version of the ReportLab toolkit, which you can get from:</p>

<p>It also requires the DMD compiler to compile the D program - this was the version used:</p>
<p>DMD32 D Compiler v2.071.2</p>

</p>
<p>This recipe shows how to publish delimiter-separated values (a commonly used tabular data format) to PDF, using the xtopdf toolkit for PDF creation. It lets the user specify the delimiter via one of two command-line options - an ASCII code or an ASCII character. As Unix filters tend to do, it can operate either on standard input or on input filenames given as command-line arguments. In the case of multiple inputs via files, each input goes to a separate PDF output file.</p>

<p>This allows you to hold on to your csv in a dict form, do lookups and modifications, and also write it in a preserved order. You can also change which column you want to be your lookup column (making sure that there is a unique id for every row of that column. In my example of usage, it assumes that both classes are contained withing the same file named 'CustomDictReader.py'</p>
