| To rephrase Visakh's question - would the query take a long time if you simply did a select from the same table with the same where clause, but without the XML PATH concatenation?You may want to look at the so-called quirky update method, which I am told is very fast. See the last example in Madhivanan's blog here: http://beyondrelational.com/modules/2/blogs/70/posts/10865/quirky-update-in-sql-server.aspxI am not a great fan of this approach, but people whose opinions I respect very much seem to swear by it - see Jeff Moden's article here for example: http://www.sqlservercentral.com/articles/T-SQL/68467/ |
