working on haskell project, i'm dealing event data type fsnotify package. constructors event all: added filepath utctime modified filepath utctime removed filepath utctime in code, i'm interested in extracting filepath event , doing same action regardless of type constructor; because of this, i'm tempted make lambda. unfortunately, code suffers reduced readability when drop case expression lambda pattern match against 3 cases; there built-in idiom extract filepath in 1 expression without having manually pattern match, given relative homogeneity of type constructors? i've tried passing expression anonymous function in call watchdir action: wm <- startmanager sw <- watchdir wm "." (\_ -> true) (\(_ f t) -> putstrln f) but, predictably, don't-care value in lambda's pattern match causes parse error. the simplest way reflect homogenity of alternatives in type declaration, instead of observing it: data action ...

i stumped here , in need of help. i have table called "2016blocks" table has rows each individual. each row has columns every day of year (365 columns each row). i have select statement return single row looks this: select * [2016blocks] ([officialid] = @officialid) the above select statement return 1 row 365 columns. each column either blank or have date in it. name of columns (blocks1, blocks2, blocks3......blocks365) i want select statement on row return columns have date in them. how do this? you'll have use unpivot function that. have 365 columns might not want mention 365 hardcoded column names. purpose can use dynamic query. can use below query in subquery or insert records in temp table , add filter blockvalue. hope helps. declare @colsunpivot nvarchar(max), @query nvarchar(max) select @colsunpivot = stuff((select ','+quotename(c.column_name) information_schema.columns c c.table_name = '2016block...
