问题 The function below is supposed compute either the Uval and Lval functions in accordance to Set and Numbers . For the first two numbers U and 52599 are in relation and L and 52550 are in relation, since the second number has the label L the Lval equation is used. The previous number is function is previous = numbers[1:] and the current function is current = numbers[:-1] . So (52550 - 52599)/52550 * -100 will be the computation for the first two numbers. The equations are supposed to be

问题 I have a query that looks at one tables field and matches the second table's field. It looks to see if the fields don't match each other. If there's no match the second table's field must replace the first tables field. I have this working EXCEPT when there's a null value in either of the two tables field. I tried using isNull() on the first table and it does select values that aren't null but if I apply the same function to the second table I get nothing in return. UPDATE [NAVAIR

问题 I have a xls with 20000 IDs I need to extract the rows of a table that have these IDs in Col1 Is there a clever way to do this in Oracle SQL ? I only have a read access to this db. I thought to slice the 20000 IDs, in order to put the first 1000 in a variable p_list1 , the next 1000 in a variable p_list2, ect and use a IN clause and union to get the whole result But I'm not used to use paramters in my query. Could you please review it ? Thanks in advance for your help DECLARE p_list1 VARCHAR2

问题 I have a database that contains a series of events and their timestamp. I find myself needing to select all events that happen between 11:00 and 11:10 and 21:00 and 21:05, for all days. So what I would do is I extract from timestamp the hour and the minute, and: SELECT * WHERE (hour = 11 AND minute <= 10) OR (hour = 21 AND minute <= 05) However, I was wondering if there's a simpler / less verbose way to do this, such as when you query between dates: SELECT * WHERE date BETWEEN '2020-07-01'
