sql server - QUOTENAME is causing conversion errors in SQL? -

edit:

ok throwing me off now, have query working twice , no reason stops working again , give me different errors each time. getting error:

msg 8115, level 16, state 8, procedure gsp_rpt_custom_extract_haven_test_2, line 12 arithmetic overflow error converting varchar data type numeric. 

it inconsistent, can take out joins , query runs join irrelevant error , work absolutly fine independantly. confused one.

end edit

i have query, lengthy one. using query bcp command why looks odd. trying add text qualifier (as bcp cannot it) using quotename(), query runs fine without quote name reason keep getting error:

msg 245, level 16, state 1, procedure gsp_rpt_custom_extract_test, line 12 conversion failed when converting varchar value '05-01-2015 12:49:05' data type smallint. 

as can see query have commented out columns have not got yet part of diagnosis. columns work ok until last 1 (the case statement) whats causing problem. said above, querty runs fine when remove quotenames.

any appreciated.

thanks
