Updating XML stored in a column via update text function????

    Hey Gurus and Grand Masters 😎

    I have xml stored in a column with data type = text. I need to update multiple substrings of data within that text column (ie update ‘<data>1</data>’ to ‘<data>Test</data>’, ‘<data>2</data>’ to ‘<data>Test2</data>’). In trying the Replace function, it returns this message: Argument data type text is invalid for argument 1 of replace function.

    In light of this, I am using the updatetext function instead. Due to the column data type of text, this function requires a delete_lengthvalue in bytes. Right now I have string length, I am looking for the best way to calculate byte length. Is there a built-in function to do this? Multiplying by a factor seems to work in some cases but not all, I am still in the midst of testing this…

    Change the text data type to XML. This is not only to match data type and data content. You'll also get rid of a deprecated data type.

    Once this is done you can use XQuery to modify the xml data in your table. It'll be a lot easier (once you got used to it).

    A good resource for XQuery is Jacob Sebastians blog.
