Hi,
I have two tables,
Table A(A_ID, Info)
Table B(B_ID, A_ID, Blah) where B.A_ID references A.A_ID
How can I detemine how many records in table B reference each unique A_ID in table A?
I've tried the following but it doesn't work:
Select A.A_ID, COUNT(B.A_ID) FROM A
JOIN B ON A.A_ID = B.A_ID
Select statement joining file1 to file2. File 1 may have 0, 1, or many corresponding rows in file2. I need to count the corresponding rows in table2. Table2 also has a Boolean column and I need to count the number of rows where it is true. So I need to count the total number of matching rows and the count of those that are set to true. This is an example of what I have so far. I had to add each column being selected into a Group by to make it work, but I do not know why. Is there some other way this should be set up.
SELECT c.CarId, c.CarName, c.CarColor, COUNT(t.TrailerId) as trailerCount, (add count of boolian, say t.TrailerFull is true)
FROM Car c
LEFT JOIN Trailer t on t.CarId = c.CarId
GROUP BY c.CarId, c.CarName, c.CarColor
Hi all,
I have the following function:
Code Block
create function udf_CountRows(@pTableName sysname)
returns int
as
begin
declare @ret int
select @ret = SUM(p.rows)
from sys.partitions p
inner join sys.objects o
on p.object_id = o.object_id
and o.[name] = 'Well'
return @ret
end
Can I trust sys.partitions to always return the correct value or does it suffer the same issue as sysindexes prior to SQL2005?
Thanks
Jamie
Is there a way to get a SQL Stored Procedure to count the number of rows returned and then store that total in a variable?

quick question
is there any way to set up a column that has the row count in it? i need this for a program i am developing and this would make it much easier to deal with. I know i can get a total count but when i run a count within a select statement i just get '1' for every row. thanks

Hi,
I have a temp table that I use to calculate prices from and I need to know how many of each row with the same serialnumber.
I figured I could add a column that contains that number. But how will I get it there?
UPDATE [_temp] T1
SET T1.SERIAL_COUNT = (SELECT COUNT(*) FROM [_temp] T2 WHERE T1.SERIAL = T2.SERIAL)
Doesn't work. Any ideas?
T-SQL counting rows with a value:
My query is like this:
SELECT
Name,
A,
B,
C,
D
FROM
Table
ORDER BY
Name
The query result looks like this:
Name A B C D
Bert 2 0 0 0
Bert 3 6 0 1
Mark 0 0 1 0
Mark 0 8 8 0
Mark 5 6 3 0
I want my result to count the cells with a value and group them on name Like this:
Name A B C D
Bert 2 1 0 1
Mark 3 2 3 0
COUNT() gives back every row from a name.
SUM() adds up the values
I have tried many things with sub queries and combined functions, but up until now with no results.
How do I do this ?

Hi,
I'm using SQL Server 7.0. My problem is that I'd like to count how many rows are in a group by. For example, here is my data:
Agent Branch
1 1
2 1
1 1
2 1
1 2
1 2
If I do this:
Select Agent, Branch
From Table1
Group By Agent, Branch
I get:
Agent Branch
1 1
2 1
1 2
What I need to do is count the records (3) in the group by. I've tried a few things but I can't seem to come up with the number of rows in a group by.
Can anyone help me?
Thanks in advance,
Darrin
i have a report with 1 group and items under the group.
i want to add a new field called Sl. no. at the group level which keeps the count on groups...by that i mean say if there are 10 groups i want the number from 1 to 10 appear against each group as
1 Grp1
2 Grp2
3 Grp3
.
.
.
10 Grp10
How can i achieve the above. I tried the rownumber but it returns the number of rows the group has. The levels i have is "table1" the main scope and "table1_Group1" the group scope which in the table1 scope.
Any help will be appreciated.
Is it posible on a query ordered by employee name, for exemple, that MSSQL gives me a position of which employee is contained on the recordset?
that's my query (simplified)
SELECT name, payment, category FROM employee_payments ORDER BY name
John, 1000, sallary
Peter, 1500, sallary
Peter, 500, other
Zeus, 1000, sallary
I want to add another field giving me the position of the employee on the recordset:
John, 1000, sallary, 1
Peter, 1500, sallary, 2
Peter, 500, other, 2
Zeus, 1000, sallary, 3
Is it posible?
hi,
i have a stored procedure SELECT UserName AS Visitor, COUNT(VisitID) AS TotalVisit
FROM UserVisits
WHERE (ProductID = @ProductID) AND (AnonimIP IS NULL)
GROUP BY UserName
UNION
SELECT AnonimIP AS Visitor, COUNT(VisitID) AS TotalVisit
FROM UserVisits AS UserVisits_1
WHERE (ProductID = @ProductID) AND (UserName IS NULL)
GROUP BY AnonimIP
this will return something like:
zuperboy90 - 4 visits
ANONIMOUS - 6 visits
85.104.103 - 2 visits etc
how can i count the rows returned in both selections (4+6+2 = 12) ?
thank you
Hi all,
Can anyone explain to me how to count number of rows per page? I need to calculate an index size, and I think the factor that contributes the most to my formula`s inaccuracies is the number of rows per page.
Thanks.

hi, I am importing data daily to many tables, I want to keep track of the #of rows for each import process. I already have created a trigger as follow:
CREATE TRIGGER tr_bcp_log ON dbo.A
FOR INSERT
AS
declare @name varchar(30),
@row_count int
select @name=name , @row_count= @@rowcount
from inserted
insert into bcp_tracks (name,row_count)
values(@name,@row_count)
GO
The problem is that I am getting a row for each inserted row in table A.for instance if I have 500 rows in table A, I will get 500 rows in the log table like this
table_name,#of rows
A 1
A 1
A 1
etc up to 500 rows for table A
This is not what I want, I want to capture the num of rows for every bcp process , so in the log table I want to see the following :
table_name, #of rows
A 500
B 600
C 450
A 250
etc
Any help ?
thanks

Hello,
Is there a way (perhaps a property) to capture the number of rows selected from a Flat File Data Flow Source without having to develop a script to loop through the rows and count them?

Hi,
I need to count and display the number of records which have GradeTitle="SHO". I'm only starting to use BI development studio and all attempts at using the built in aggregate functions have failed.
Also, the report I wish to create has a fixed number of columns and a fixed number of rows as the info being displayed is really only counting values in the DB. I tried using Table but multiple rows were created.
I'd appreciate if anyone could point me in the right direction, as searching this forum turned out to be pretty fruitless for me.
Thanks in advance,
John
I have a table with the following data (sample)
Type Year Price
---- ---- -----
A 00 100.00
A 00 200.00
A 01 105.00
A 01 105.00-
B 00 100.00
B 00 200.00
B 01 105.00
B 02 00.00
I need to establish a Type Count. The business rule to do the count is -
For a particular type, take a single year and add up the price. If the price is greater than zero then count = 1 else count = 0. After completing the counts for all the years for a particular type, add up the counts.
Based on the business rule for the above sample data I should have the following count.
Count -
Type A = 1 (For Year 00, price = 300.00 so count = 1 and for year 01, price = .00 (105 + 105.00 - ) and so count = 0. add counts to get a total of 1)
Type B = 2 (For Year 00, price = 300.00 so count = 1 and for year 01, price = 105 and so count = 1 and for year 02 price = 00 so count = 0. add counts to get a total of 2)
How do I implement this count using a query. I am free to add any indicator columns that may be required to perform the counting.
Let me know.
Thanks
Vivek
I'm currently running a reorganize on a large table of ~60 gig. I started the reorganize when I noticed the fragmentation was 97.95%!!!
Well the reorganize has been running for 25 hours now and apparently bulk inserts cannot happen during this time since my SSIS package just bombed trying to prepare for bulk insert.
Anyway, my question is can I cancel this reorg? I didn't start the reorg through the query analyzer. I saw this cute little reorganize button when I right clicked my indexes, properties, fragmentation in the SQL 2005 management studio. I clicked it and then clicked ok.
I know I should have done an alter rebuild but I wasn't comfortable with the process and did the one click solution that is now killing me.
What happens if I go into task manager and shut down the process? Am I risking a serious side effect of corruption or will SQL just stop so I can rebuild the index properly?
is there a way to get a count of records for each table in a database by table in one query? I can query each table using a count, but this is pretty tedious when you have 50+ tables. Anybody have any ideas?

Hi,
When expoting data from excel to sql server table, using SSIS package, after exporting is done, how would i check source rows are equal to destination rows. If not to throw an error message.
How can we handle transactions in SSIS
1. when some error/something happens during export and the # of rows are not exported fully to destination, how to rollback the transaction in SSIS.
Any sort of help would be highly appreciated.
