Analyze Key Influencers Issue........
Oct 23, 2007
Excuse the elementary question; I am new to this feature.
No matter what dataset I use, I get the following error:
"The task was not able to detect any key influencers for the 'xxx' column. The values of 'xxx' seem unrelated to values of other columns."
Any ideas on what is happening here?
Here is the sample dataset:
Loan Amount

5,000
52.0%

Msg 245, Level 16, State 1, Procedure CompactL1RecordsFromfirstINTRAD, Line 177
Conversion failed when converting the varchar value
'DECLARE rows_cursor CURSOR FOR
SELECT ask, dateTimed FROM iDay_Compr_GOOG
WHERE DAY (dateTimed) = ' to data type int.
I get this message while executing a stored procedure. It works "half way" but skips this statement and the whole block as a result. In the table @table_name ask is declared as float and dateTimed as DateTime. Similar statements work happily in other stored procedures with no problem. Even in the same stored procedure I have places where I use DAY (dateTimed) and they seem to work as far as I can see although it is a very branched out code with many IF ... ELSE's.
SET @SQL = 'DECLARE rows_cursor CURSOR FOR
SELECT ask, dateTimed FROM '+@table_name+'
WHERE DAY (dateTimed) = '+@day+' AND NOT ask = 0'
exec sp_sqlexec @SQL
OPEN rows_cursor
FETCH LAST FROM rows_cursor INTO @askQ, @lastTableDateTime
SET @SQL = 'UPDATE '+@table_name+' SET askSize = askSize + '+@askSize+'
WHERE dateTimed = '+@lastTableDateTime+' AND ask = '+@askQ
exec sp_sqlexec @SQL -- <== this is line 177
CLOSE rows_cursor
DEALLOCATE rows_cursor
Another puzzle for me is the line number. I used Edit-->GO TO--> 177 to single the line out and it seems to point to a different exec sp_execsql @SQL statement, the one that is down the road.
I can make neither head nor tail out of it. I am sure Jens, Cetin or Andrea or whoever stumble on this post will be able to figure this out. Anyone else's help will also be appreciated.
Many thanks.

Edit 2007-8-9:
Added code to show database file sizes. Not really closely related to tables sizes, but a lot of the people who need this want to know why their database it so large, so it may help to know which files, especially the logs, are so large, and if the files have empty space in them.
-- Script to analyze table space usage using the
-- output from the sp_spaceused stored procedure
-- Works with SQL 7.0, 2000, and 2005
set nocount on
print 'Show Size, Space Used, Unused Space, Type, and Name of all database files'
select
[FileSizeMB]=
convert(numeric(10,2),sum(round(a.size/128.,2))),
[UsedSpaceMB]=
convert(numeric(10,2),sum(round(fileproperty( a.name,'SpaceUsed')/128.,2))) ,
[UnusedSpaceMB]=
convert(numeric(10,2),sum(round((a.size-fileproperty( a.name,'SpaceUsed'))/128.,2))) ,
