I was going to suggest something similar, but there are some issues with this as well.

First, one must make sure to still commit at regular intervals. The original poster mentioned 10M rows (I'm guessing 10 million) - you'd have to have a rather large transaction log if you're going to batch all of these rows in a single transaction.

Second, batching may not necessarily gain you all that much - certainly with Sybase the total amount of work that the database needs to do whether you batch transactions or not is the same - the only real difference is that rows are only committed to the "real" table when the server gets the COMMIT TRAN command instead of placing each row there individually (i.e. the total amount of disk IO is the same).

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.
