case-when

问题 I have a state machine with 6 states(3 main states). Only the last state is working but the first 2 doesn't(out of 3).Only the last state is working. I found out the problem, when I remove the debounce circuit it works, but I need the debouncing circuit. I got the debouncing circuit from the internet. I would be glad if someone can help. type SM_STATES is (state_column_1, scan_col_1, state_column_2, scan_col_2, state_column_3, scan_col_3); signal my_state : SM_STATES := state_column_1; Below

问题 Learning about CASE WHEN, and I've come across a use case when I see multiple locale codes in Analytics. This is a much simpler question that is much easier to answer and read, than my prior question that was posted. Examples are: en-us (english US) en-au (english australia) en-br (english brazil) es-es (spanish spain) es-419 (spanish-latam) pt-br (portuguese brazil) pt-pt (portugal) How do I aggregate these in BigQuery so that instead of counting distinct values, I can count the number of

问题 Ok - hoping someone can help as I'm struggling here. Have tried using sum(case when), count(*), subqueries with no success. Essentially I have two queries I am trying to combine into one, grouped by the same parameter. The queries: Query 1: SELECT u.username, count(*) as 'Total' FROM log1 L1 JOIN users u on u.userref = L1.userref WHERE L1.date between @FromDate and @ToDate GROUP BY u.username ORDER BY u.username Query 2: SELECT u.username, count(*) as 'Total' FROM log2 L2 LEFT JOIN users u on

问题 Here's a SQL query that works absolutely fine: DECLARE @IncludePTO AS CHAR SET @IncludePTO = 'Y' SELECT HQCO.HQCo, HQCO.Name, PREH.PRDept, PREH.Craft, HRRM.PositionCode, PRTH.Employee, PREH.LastName, PREH.FirstName, SUM(PRTH.Hours) AS Hrs FROM PREH INNER JOIN HRRM ON PREH.PRCo = HRRM.HRCo AND PREH.Employee = HRRM.HRRef INNER JOIN PRTH ON PREH.PRCo = PRTH.PRCo AND PREH.Employee = PRTH.Employee INNER JOIN HQCO ON PRTH.PRCo = HQCO.HQCo WHERE (dbo.PRTH.PREndDate BETWEEN '1/1/2012 00:00:00' AND '1

问题 I am trying to set 2 declared variable with case when blocks Here's my code: DECLARE @like bit,@dislike bit if exists ( select * ,@like = (CASE WHEN likeordislike = 1 THEN 'true' ELSE 'false' END) ,@dislike=(CASE WHEN likeordislike = 0 THEN 'true' ELSE 'false' END) from likeordislike ) But when I execute query throws errors: Msg 102, Level 15, State 1, Line 4 Incorrect syntax near '='. Everything is ok? Couldn't understand 回答1: if (select count(*) from likeordislike where user = @user and

问题 I have a data frame with: customer_id [1,2,3,4,5,6,7,8,9,10] feature1 [0,0,1,1,0,0,1,1,0,0] feature2 [1,0,1,0,1,0,1,0,1,0] feature3 [0,0,1,0,0,0,1,0,0,0] Using this I want to create a new variable (say new_var) to say when feature 1 is 1 then the new_var=1, if feature_2=1 then new_var=2, feature3=1 then new_var=3 else 4. I was trying np.where but though it doesn't give me an error, it doesn't do the right thing - so I guess a nested np.where works on a single variable only. In which case,

问题 I have this stored procedure, its working CREATE PROCEDURE myrange() BEGIN SET @start = 0; PREPARE stmt FROM ' SELECT firstname FROM peoples ORDER BY id LIMIT ?,1 INTO @name'; WHILE @start < 5 DO EXECUTE stmt USING @start; CASE WHEN @name = 'Ana' THEN INSERT INTO mytable (log) VALUES('yes'); ELSE INSERT INTO mytable (log) VALUES('no'); END CASE; SET @start = @start + 1; END WHILE; END; but, if I delete from this procedure, this piece of code: ELSE INSERT INTO mytable (log) VALUES('no');

问题 Systems: -Call Center phone system: incoming calls accompanied by the source number, aka Caller ID, aka "ANI" -SQL Server 2005 - the "data warehouse" which stores customer phone numbers ([cANI]), cust names, location, etc. in a table [CustDataByANI] -Stored Procedure - call center software passes the Caller ID (aka ANI) to a SP as a parameter which uses it to perform a presently simple SELECT statement on the CustDataByANI table....WHERE [cANI] = @ANI. This works wonderfully, provided the
