between

问题 Simple question: I need a solution so that I can find, lets say names, between A-F, INCLUDING all names that start with F. If you use BETWEEN or A >= value <= F you find out that it stops at F. So I am posting this for suggestions. NOTE: User will see 2 textboxes that accept a range user can type. The user refines how far to go in F boundary as such: User types in 'Fa' means the result should return: Fauder, Fail, Famber, ... etc I have currently 2 solutions but there's got a be a better way.

问题 I'm trying to use the BETWEEN with column names instead of direct values, something like this: SELECT * FROM table WHERE column1 BETWEEN column2 AND column3; This is returning something like 17 rows, but if i write: SELECT * FROM table WHERE (column1 <= column2 AND column1 >= column3) OR (column1 >= column2 AND column1 <= column3) i get around 600 rows.. In both cases i only get rows where column1 value is actually the middle value, but 2nd method gives me much more results, so 1st method has

问题 Following the my question I have the following tables the first (Range) includes range of values and additional columns: row | From | To | Country .... -----|--------|---------|--------- 1 | 1200 | 1500 | 2 | 2200 | 2700 | 3 | 1700 | 1900 | 4 | 2100 | 2150 | ... The From and To are bigint and are exclusive. The Range table includes 1.8M records. Additional table (Values) contains 2.7M records and looks like: row | Value | More columns.... --------|--------|---------------- 1 | 1777 | 2 | 2122

问题 I need my audit list to (1) add a time stamp in the end of current line and then (2) copy the line to the other sheet, when there is a "N" or "n" marked in the specified column. The idea is to get a summary of copied non-conformities. My trouble is that in the case of the code I use, it only deals with the first column correctly. It does nothing with others. I use the code (below). Sub Worksheet_Change(ByVal Target As Range) On Error GoTo ErrHandler Application.EnableEvents = False If Target

问题 I have a query with a where condition like so: WHERE A.event_date BETWEEN B.start_date AND B.end_date The complexity is that if B.start_date is NULL, it means from time immemorial, similarly B.end_date is NULL, it means the present. So I still want to select a row where A.event_date > B.start_date and B.end_date is NULL , for example. The long-winded way to do this is WHERE A.event_date BETWEEN B.start_date AND B.end_date OR (A.event_date > B.start_date AND B.end_date IS NULL) OR (B.start

问题 I have a question about this query: SELECT * FROM runs WHERE (NOW() BETWEEN began_at AND finished_at) Do you think it makes sense to create composite index for began_at and finished_at columns? Or it makes sense to create index only for began_at? 回答1: Your style is very uncommon. Most people would probably write WHERE began_at < NOW() AND finished_at > NOW() However. I would recommend putting an index on both fields. A combined key wont be of use to you because you it would only speed up

问题 quick simple question In the following example of an external CSS page; body { background-image: url(background.jpg); } header { background: url(background.jpg); } I understand they are effecting different element selectors, my question is what is the difference between using background vs background-image?
