SQL 2000I 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 otherconstraints.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 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 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?
With the function below, I receive this error:Error:Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing.

Hello all,
I would like to use MDX to identify "contracts" which are in a table A and not in a table B, and count them to have a total per "company".
It should be something like:
Contract / Flag contracts not in table B (1=yes, 0=not)
---------------------------------------------------------------
Contract 1 1
Contract 2 0
Contract 3 1
Contract 4 1
Contract 5 0
Contract 6 0
TOTAL 3
So far I know how to distinguish at contract level which records belong to table A and not table B, but I do not have the total for the company.
In SQL it should be something like that:
SELECT Company,count(*)
FROM tableA
left join tableB
on tableA.Contract = tableB.Contract
WHERE tableB.Contract is null
GROUP BY Company
Thanks,
Guillaume
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!
Xiao
ps. that table has about 400,000 rows, and size of 20 MB

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 have a link that inserts postid, catid, and postdate.

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.

existing table looks like this:

But can I add that to the table somehow so it does it automagically???
