I have a question related to a SQL Server query. I want to count all '//' in a dataset. The dataset contains a code. Through counting the '//' i want to declare it as a Comment, IF EVERY SINGLE ROW contains at least one time the string '//'.
Actually I've count the amount of '//' in a dataset, but i don't know how should i continue.
select col1, col2, LEN(col3) - LEN(REPLACE(col3, '//', '' )) AS col3counter
from #tmp
You are going to get twice the count. So either divide by 2 or:
select col1, col2,
( LEN(col3) - LEN(REPLACE(col3, '//', 'x' )) ) AS col3counter
from #tmp
Sorry for double-posting but I solved the issue on my own :-). Code is...
select col1, col2, col3, col4,
LEN(col3) - LEN(REPLACE(col3, '//', ' ' )) AS col3commentcount,
LEN(col3) - LEN(Replace(col3,(char(13)+char(10)),' '))+1 as col3rowcount,
LEN(col4) - LEN(REPLACE(col4, '//', ' ')) AS col4commentcount,
LEN(col4) - LEN(REPLACE(col4,(char(13)+char(10)),' '))+1 as col4rowcount
from #tmp
where LEN(col3) - LEN(REPLACE(col3, '//', ' ' )) =
LEN(col3) - LEN(Replace(col3,(char(13)+char(10)),' '))+1 OR
LEN(col4) - LEN(REPLACE(col4, '//', ' ')) =
LEN(col4) - LEN(REPLACE(col4,(char(13)+char(10)),' '))+1
and idcheck=0
order by col1
