lets have table set of different columns (offcourse), example : table id col1 integer(1), // 0 || 1 col2 // --||-- col3 // --||-- col4 // --||-- is possible, in 1 query select 4 rows col1=1 , select 4 rows col2=1 , select 4 rows col3=1 etc etc. think understand mean. what have done far make 4 different queries or make 1 query , (col1 = 1 or col2=1 or... etc). this works if limit result lets 16, might 15 rows col1=1 , maybe 1 row col2=1 , col3,col4 - no result. so dear fellas; there way in 1 query (i think not) select * table col1=1 limit 4 union select * table col2=1 limit 4 union select * table col3=1 limit 4 union select * table col4=1 limit 4 this 1 result 16records max. if there less 4rows certin criteria, you'll less rows. duplicates removed, resulting in less 16 rows. not different rows. if single row col1=1 , col2=1 , might returned twice if use union all , union slower large datasets

svn commit on specific repository not show successful message in commit dialog instead commit dialog hangs on "committing transaction" happens specific repository, have updated repo permission of repo in server did svn verify find if there corrupt revisions.
