| Is there an easy way to run a select statement with a like clause against column(s) of data type xml?This is just for a quick check on something, so if there's going to be significant overhead involved it's not worth doing. |

| There is the exist() method, which you can use together with the xquery functions "contains" or "substring". (Contains is like a charindex function in SQL). Alternatively, you can cast the XML to varchar and then use the like operator. Most likely you do not want to cast the whole XML column into varchar - it might be 2G Bytes long!! Examples of both these approaches are on this MSDN page: http://msdn.microsoft.com/en-us/library/ms345117(v=sql.90).aspx. Also, all these searches are case-sensitive in XML even if our database/table collation is case-insensitive. |

| Thanks guys. For some reason I thought you weren't allowed to cast xml to character data types, but on reflection I think that only applies to ntext. |

Easy way to get a "like" effect on xml?
