SQL 2000
I have a table with 5,100,000 rows.
The table has three indices.
The PK is a clustered index and has 5,000,000 rows - no other
constraints.
The second index has a unique constraint and has 4,950,000 rows.
The third index has no constraints and has 4,950,000 rows.
Why the row count difference ?
Thanks,
Me.

I have a table that seems to have a bad index. When I do the followingquery I get inconsistant and needless to say incorrect results.select count(*) from mytable where mycolumn = 1If I remove the index from "mycolumn" the query works correctly. If Iadd the index back (even with a new name etc...) it doesn't workright.Has anyone ran into this? or does anyone know how I can fix thisproblem?It seems that removing the index is not really removing everythingbecause when I add a new one I get this same problem... btw, this isisolated to this column on this table. all other indexes within thedatabase are fine.Any help would be appreciated.Thanks,dharper

I use SQL 2000
I have a Column named Bool , the value in this Column is 0�0�1�1�1
I no I can use Count() to count this column ,the result would be "5"
but what I need is "2" and "3" and then I will show "2" and "3" in my DataGrid
as the True is 2 and False is 3
the Query will have some limited by a Where Query.. but first i need to know .. how to have 2 result count
could it be done by Count()? please help.
thank you very much
The following query returns a value of 0 for the unit percent when I do a count/subquery count. Is there a way to get the percent count using a subquery? Another section of the query using the sum() works.
Here is a test code snippet:
--Test Count/Count subquery
declare @Date datetime
set @date = '8/15/2007'
select
-- count returns unit data
Count(substring(m.PTNumber,3,3)) as PTCnt,
-- count returns total for all units
(select Count(substring(m1.PTNumber,3,3))
from tblVGD1_Master m1
left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID
Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9
and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0
and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)
and v1.[Date] between DateAdd(dd,-90,@Date) and @Date) as TotalCnt,
-- attempting to calculate the percent by PTCnt/TotalCnt returns 0
(Count(substring(m.PTNumber,3,3)) /
(select Count(substring(m1.PTNumber,3,3))
from tblVGD1_Master m1
left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID
Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9
and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0
and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)
and v1.[Date] between DateAdd(dd,-90,@Date) and @Date)) as AUPct
-- main select
from tblVGD1_Master m
left join tblVGD1_ClassIII v on m.SlotNum_ID = v.SlotNum_ID
Where left(m.PTNumber,2) = 'PT' and m.Denom_ID <> 9
and v.Act = 1 and m.Active = 1 and v.MnyPlyd <> 0
and not (v.MnyPlyd = v.MnyWon and v.ActWin = 0)
and v.[Date] between DateAdd(dd,-90,@Date) and @Date

I noticed a web query was running unreasonably slow, so I investigated
further and found out that query was searching on the primary key field
of a table, but instead of using the index seek, it acutually did a index
scan. I don't know why that query didn't use PK index, since the search
was on PK itself.
There is an other SQL server which has the exact same table(same data), I ran
that query against that table, and the query did what it suppose to do,
it used PK index, and was able to retrieve data very fast.
So I ran following commands and see if the systerm would use PK when
running the query:
(recreate all index(all non clusted))
sp_updatestat (all indexes)
sp_recompile (table)
But it didn't work, PK index was still not been used when that query was run.
Although I were able to slove the problem by force the web query to
use PK index, but I really don't like to force useage on any index.
So I thought there might be some corruptions in that table.
I didn't a dbcc showcontig, it showed that Page Density is 95%
and Frag is only 3.4% I also didn't some manual calculation
and only found very very small amount of unused space.
But when I ran sp_spaceused against that table,
and found out that the ROW COUNT for that table is 0!
but if I did select count (*), it returned the correct row count.
So I ran following commands
dbcc checkdb --- no error reported
dbcc checktable --- no error reported
dbcc updateusage (table) --- still got 0 row cound for sp_spaceused
(0 rows count in sysindexes for that table)
Question 1: Why PK index was not been used when the "where" of that query
was PK itself.
Question 2: Why that table has 0 row count?
Question 3: How can I fix the row count problem without introducing a
clustered index on that table or rebuilding that table?
Thanks guys!

ps. that table has about 400,000 rows, and size of 20 MB
select singer.id,singer.singer,count(albums.id) from singer inner join albums on albums.singer=singer.id where singer.country='England' order by singer.singer
doesnt't work because of the count(albums.id)
how can I do ?

Is it possible to directly get the row count of a different table in a RS2005 report?
I'd like to use this row count number in a calculation in another table...
This would be a lot cleaner than creating a new dataset to provide me with this value.
Thanks!

I would like to find out how to capture record count for a table in oracle using SSIS and then writing that value in a SQL Server table.
I understand that I can use a variable to accomplish this task. Well first issue I run into is that what import statement do I need to use in the design script section of Script Task. I see that in many examples following statement is used for SQL Server databases:
Imports System.Data.SqlClient
Which Import statement I need to use to for Oracle database. I am using a OLE DB Connection.
any idea?
thanks
I have a link that inserts postid, catid, and postdate. I am trying to get count of catid(how many times its in the table) then display the number on a page. i have never tried this before. one more thing.

View 2 Replies View RelatedOkay I wanted to get this to work right so I am wondering what I am doing wrong here.
"SELECT COUNT(A.Status) AS TOTAL FROM tts_tickets A,tts_reporters B WHERE A.Ref_Reporter_ID="123"AND A.Status=1"
I need to count the status options but only where from table b is the ID equal to the ID in question.
How do I do this?
I am inserting data from one table into another. To simplify:
Table 1 has columns:
1.A, 1.B, 1.C, 1.D
Table 2 has columns
2.A, 2.B, 2.C, 2.D, 2.Tag
where 2.Tag is a counter of all unique combinations of 1.C and 1.D.
Not a count of how many records for each combination.
Therefore, if Table 1 is
x - x - x - x
x - x - x - x
x - x - x - x
x - x - x - y
x - x - x - z
then, table 2 is
x - x - x - x - 1
x - x - x - y - 2
x - x - x - z - 3
anyone help me w/ the sql on that ?
i was thinking of putting a variable in the select statement, but was unable to increment it.
thanks
Hi,
I want a count of distinct rows in a table through a single query -- is it possible?
eg.
table-
create table ch1 (a int, b int, c int, d int)
insert ch1 values (1,1,1,1)
insert ch1 values (2,2,2,2)
insert ch1 values (1,1,1,1)
insert ch1 values (2,2,2,2)
insert ch1 values (1,3,4,5)
Here distinct row count in a table is 3 which I want to achieve thro a query.
if I do
select count(distinct a) from ch1 it works fine and gives me output as 2.
but this is not working
select count(distinct a,b,c,d) from ch1 - any workaround to find the distinct row count in a table??
Please reply.
Cheers!
Ram.

I want to list all of the houses which has HouseName, Address, HouseNo. Then I want to show a column for the number of guests who visited it.

I have 2 tables:
TableA:
Name
UserA
UserB
UserC
Table B:
Name Data
UserA xxx
UserB asdasd
UserB ewrsad
UserC dsafasc
UserA sdf
UserB dfvr4
I want to count the total entries in Table B for every user in Table A. The output would be:
Name Count
UserA 2
UserB 3
UserC 1
I can use a Select Count statement, but I will have to make a SQL call for every user in Table A. Also, Table A is dynamic, so the users are always changing. Can this be incorporated into one SQL call to count the total rows in Table B for each user in Table A?
Is there a difference in performance when using count(*) or count(columnname)?

I have a table for blog comments I want to add a column that counts the number of comments for each article.
existing table looks like this:
