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.
In database management systems, query by example (QBE) refers to a method of forming queries in which the database program displays a blank record with a space for each field. You can then enter conditions for each field that you want to be included in the query. For example, if you wanted to find all records where the AGE field is greater than 65, you would enter >65 in the AGE field blank. QBE systems are considered easier to learn than formal query languages.
