mysql - Join two sql queries into one -


i have 2 mysql queries , combine them one.

this 1 "merges" 2 columns one.

select description  case      when checkbox2 = '2' '2'     when checkbox2 = '1' '1'     when checkbox2 = '0' '0'        when checkbox1 = '1' '1'     when checkbox1 = '0' '0' end 'checkbox_merge',  table2  left join table3      on table2.id2 = table3.id2 order table2.id2

this 1 takes 2 tables , pivots names (a->d) , uses them columns draw grid if will. 

select description    max(case when column1 = 'a' checkbox1 else '-' end) 'a',   max(case when column1 = 'b' checkbox1 else '-' end) 'b',   max(case when column1 = 'c' checkbox1 else '-' end) 'c',   max(case when column1 = 'd' checkbox1 else '-' end) 'd',  table1 join table2     on table2.id = table1.id table2.id = var1 , table1.id = var1 group description

so take first query , use checkbox_merge in place of checkbox1 in second query.

any ideas how accomplish this?

try this:

select    description,   max(     case          when column1 = 'a'          (             case                  when checkbox2 = '2' '2'                 when checkbox2 = '1' '1'                 when checkbox2 = '0' '0'                    when checkbox1 = '1' '1'                 when checkbox1 = '0' '0'             end         )      else '-'      end   ) 'a'     table1 join table2     on table2.id = table1.id left join table3      on table2.id2 = table3.id2      table1.id = var1 group description
