sql server - Combining several query results into one result -


i using sql server. have 5 tables (mtable, c1table, c2table, c3table, c4table).

in mtable have 4 queries , each 1 of them gives correct result:

query 1:

select      mtable.cid, mtable.col1, mtable.col2, mtable.col4, mtable.col5,      mtable.col6, mtable.col7, mtable.col8, mtable.col9, mtable.col10,      mtable.col11,      c1table.col12, c1table.col13, c1table.col14, c1table.col15       mtable  left outer join      c1table on mtable.col2 = c1table.col2       (mtable.col6 = 0)      , (mtable.col5 = 0)      , (mtable.col4 = 0)      , (mtable.col2 > 0)

query 2:

select       mtable.cid, mtable.col1, mtable.col2, mtable.col4, mtable.col5,      mtable.col6, mtable.col7, mtable.col8, mtable.col9, mtable.col10,      mtable.col11,      c2table.col12, c2table.col13, c2table.col14, c2table.col15       mtable  left outer join      c2table on mtable.col4 = c2table.col4       (mtable.col6 = 0)      , (mtable.col5 = 0)      , (mtable.col4 > 0)

query 3:

select      mtable.cid, mtable.col1, mtable.col2, mtable.col4, mtable.col5,      mtable.col6, mtable.col7, mtable.col8, mtable.col9, mtable.col10,      mtable.col11,      c3table.col12, c3table.col13, c3table.col14, c3table.col15       mtable  left outer join      c3table on mtable.col5 = c3table.col5       (mtable.col6 = 0)      , (mtable.col5 > 0)

query 4:

select      mtable.cid, mtable.col1, mtable.col2, mtable.col4, mtable.col5,      mtable.col6, mtable.col7, mtable.col8, mtable.col9, mtable.col10,      mtable.col11,      c4table.col12, c4table.col13, c4table.col14, c4table.col15       mtable  left outer join      c4table on mtable.col6 = c4table.col6       (mtable.col6 > 0)

now should able create query combines results one. gives correct result amount:

select      sum(thiscount) expr1       (select count(*) thiscount       mtable       left outer join c1table on mtable.col1 = c1table.col1       (mtable.col4 = 0)         , (mtable.col3 = 0)         , (mtable.col2 = 0)         , (mtable.col1 > 0)        union        select count(*) thiscount       mtable mtable_3       left outer join c2table on mtable_3.col2 = c2table.col2       (mtable_3.col4 = 0)         , (mtable_3.col3 = 0)         , (mtable_3.col2 > 0)        union        select count(*) thiscount       mtable mtable_2       left outer join c3table on mtable_2.col3 = c3table.col3       (mtable_2.col4 = 0)         , (mtable_2.col3 > 0)        union        select count(*) thiscount       mtable mtable_1       left outer join c4table on mtable_1.col4 = c4table.col4       (mtable_1.col4 > 0) ) x

but need have list of each result (now should have result of 3 000 rows).

i have tried "union all", getting error. doing wrong?

thanks
