问题 I am using a select count distinct to count the number of records in a column. However, I only want to count the records where the value of a different column is 1. So my table looks a bit like this: Name------Type abc---------1 def----------2 ghi----------2 jkl-----------1 mno--------1 and I want the query only to count abc, jkl and mno and thus return '3'. I wasn't able to do this with the CASE function, because this only seems to work with conditions in the same column. EDIT: Sorry, I

问题 I have a very large MySQL statement looped through php foreach and each loop connected to the previous with union all. I will simplify the statement to the core of my problem, if needed I can of course also add more details later on request. I have this table +--------+-----------+-----------+ | ID | LANG | TITLE | +--------+-----------+-----------+ | 1 | EN | T-A | +--------+-----------+-----------+ | 1 | FR | T-A | +--------+-----------+-----------+ | 2 | FR | T-B | +--------+-----------+--

问题 MYSQL, what I want is like update tablename case fieldA when value1 then set fieldX0=xxx,fieldX1=bbb,fieldX2=ccc ... when value2 then set fieldY0=yyy,fieldY1=eee,fieldY2=fff ... end what is the right and simple syntax for it? thank you very much. 回答1: It should be written this way: UPDATE tablename SET fieldX = CASE WHEN fieldA = 'value1' THEN 'xxx' ELSE fieldX END, fieldY = CASE WHEN fieldA = 'value2' THEN 'yyy' ELSE fieldY END WHERE fieldA IN ('value1', 'value2'); Note that: I wrote the

问题 I am rewriting my sql to reduce the cost of execution and wondering if there is an efficient way to write the below CASE WHEN statements used in WHERE condition: SELECT l.*,tg.* FROM RefTable tg, InputTbl l WHERE tg.areascheme = l.areascheme AND tg.countrycode = l.strareabriefnamel1 AND ( CASE WHEN l.strareabriefnamel2 IS NULL THEN '' ELSE tg.areacode END ) = COALESCE( l.strareabriefnamel2,'' ) AND ( CASE WHEN l.strareabriefnamel3 IS NULL THEN '' ELSE tg.subareaname END ) = COALESCE( l

Specifically, I want to change the datePart in the dateDiff function if foo is = 0 SELECT foo, bar, test FROM table WHERE bar = 1, CASE WHEN foo = 0 AND dateDiff(dd, getDate(), 2 ) < test ELSE AND dateDiff(hh, getDate(), 2 ) < test END 回答1: Try this one - SELECT foo, bar, test FROM [table] WHERE bar = 1 AND ( ( foo = 0 AND DATEDIFF(dd, GETDATE(), 2 ) <

问题 I have a SQL Server stored proc that contains a CASE statement. However, I need to append the values if multiple conditions are true.
