Now, I think they are yellow loosestrife. I am worried the shrubs might be invasive. According to what I could find in my books, only Purple loosestrife is invasive but Yellow is not invasive. As you can see from the picture below I am about to throw them away, then I thought about bringing the situation to this forum.t is not invasive but it does spread. I just rip out what I don't want each spring. It's a wonderful perennial that blooms much longer than most perennials. I am amazed to see a variegated yellow loosestrife, ie, one with green and white foliage rather than plain green.
A query is a request for data results, for action on data, or for both. You can use a query to answer a simple question, to perform calculations, to combine data from different tables, or even to add, change, or delete table data. Queries that you use to retrieve data from a table or to make calculations are called select queries.
The exist() method in the WHERE clause returns 1 (True) if the XML does not include any <Specifications> element. Note the use of the not() function (XQuery). The sql:column() function (XQuery) function is used to bring in the value from a non-XML column. This query returns an empty rowset. The query specifies query() and exist() methods of the xml data type and both these methods declare the same namespaces in the query prolog. In this case, you may want to use WITH XMLNAMESPACES to declare the prefix and use it in the query.
