Hello,
I want to share my experiences about using insert into exec which may
help others .
Using SQL Server 2000, SP3 .
Two Proceduers - Parent SP caliing a Child SP (nested ) . No Explicit
transactions .
I have defined a # table in Parent SP and calling a Child SP like this
insert into #temp exec childsp ......
Child SP has Select * from local # temp table ( local to child SP
) as the last statement .
When number of records are less ( around 1000 - 5000) Parent SP
executes but slow .
When the Child SP returns higher number of rows ( 1,00,000 or more )
the SP will be running for hours with out completion .
Although executing the child SP , with exec ChildSP .... with same
parameters it is completed in 2 mins for 3,00,000 rows .
Resolution : - Define a temp table (say #tempChild ) in the Parent SP
..
In the Child SP instead of select * replace with insert into
#tempChild select * from ...
Also note that this problem is not noticed in SQL 2000 Server with SP4
..
This may be due to SP executing in implicit transactions .

procedures, there is an article on my web site: http://www.sommarskog.se/share_data.html.

I am trying to write a report that calculates the average number of sales
over 7, 14, 31 and 365 days for each hourly period of the day. the problem
is it takes over 4 minutes to run.

Average Xactions per Hour
7 Days 14 Days 31 Days 365 Days
00:00 - 01:00 1,141.6 579.2 261.6 28.8

Hi,
I have a stored procedure, that works perfectly when run from the query
analyser, however if I run it through access vba, (using exec) I get a
runtime error 208: invalid object name '#tmpContact'.
Any ideas why this happens? The temporary table #tmpContact is used in
the procedure, but as I say, it all works fine from the analyser.
