sql - mysql procedure order by clause conditional -


good day,

how make sql code below conditional 1 changing asc or desc value:

order   inventory_quantity.product_color_name desc

i've tried case statement got error

order   case product_color_name_sort when product_color_name_sort = 'asc' inventory_quantity.product_color_name end asc

also tried if statement still error

order   inventory_quantity.product_color_name if(product_color_name_sort = 'asc', 'asc', 'desc')

is possible?

thanks

according mysql documentation not possible.

[order {col_name | expr | position} [asc | desc], ...]

reference: http://dev.mysql.com/doc/refman/5.7/en/select.html

reference2: http://dev.mysql.com/doc/refman/5.7/en/expressions.html

you can try move logic in select clause , order new created column

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
