( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I have a legacy database (actually a single fully de-normalized table with MANY columns) that I need to move over to SQL and a more orderly data structure. However, much of the data was entered as free-text, so I have columns of things such as names, cities, etc. that vary slightly depending on who did the entering. In the simplest cases, extra white space or different capitalization are used. In more complex cases, nouns are spelled differently or even a word (like a middle name) is left out. So, I need to somehow consolidate these textual variations describing the same thing into a single entity. Concrete example:
Promessa High Spirits
Promessa high Spirits
Promessa Hgh Spirits
Promessa high spirits
These all represent the same animal. I would like to "discover" that (or at least be alerted to the situation) without having to go through the 50000 records like this that I have.

Thanks,
Sean

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
