I think I am asking this in the right place.
I'm trying to get a record count from a table with 30million items and it takes forever.
Here is my code:
SELECT COUNT(f_id) AS 'ROWCOUNT' FROM tablename
Is there a faster way.
BTW f_id is primary key indexed.
Thanks
Hello,I know that I've seen this question asked on here before, but I can'tfind an answer that gives me the performance that I need.I have a table that stores events for users:CREATE TABLE Lead_Action_History (lead_action_seq INT IDENTITY NOT NULL,lead_action_date DATETIME NOT NULL,lead_seq INT NULL,operator_id VARCHAR(20) NOT NULL,call_time INT NOT NULL,CONSTRAINT PK_Lead_Action_History PRIMARY KEY (lead_action_seq) )GOThe table has a foreign key to another table through the lead_seqcolumn:CREATE TABLE Lead_Master (lead_seq INT IDENTITY NOT NULL,state CHAR(2) NOT NULL,CONSTRAINT PK_Lead_Master PRIMARY KEY (lead_seq) )GOI need to write a query that will give me a sum of call_time brokendown by a column that is in the table joined through the lead_seq.However, if the lead_seq for a row is NULL then I need to use thelead_seq for the previous row (based on lead_action_date) for the sameoperator.This is what I came up with:SELECT LM.state, SUM(call_time)FROM Lead_Action_History LAHINNER JOIN Lead_Master LM ON (LM.lead_seq = LAH.lead_seq)OR (LAH.lead_seq IS NULLAND LM.lead_seq = (SELECT TOP 1LAH2.lead_seqFROMLead_Action_History LAH2WHERELAH2.operator_id = LAH.operator_idAND LAH2.lead_seqIS NOT NULLORDER BYLAH2.lead_action_date DESC))GROUP BY LM.stateThe problem is that Lead_Action_History has millions of records andany solution that I've found involves one or more subqueries on itwhich kills performance. I am going to look at using a covering indexwith the solution above, but I thought that someone here might haveanother way of doing this.I can't really change the structure, but I can play with the indexing.I would still be curious though how other people model this type oftemporal data in a way that makes it easy to work with.Thanks!-Tom.

I have a dts package that export data from a database to a text file. I could like to create a validation script to coun the data in the database that should be exported to file and then re-count again after the data is in the text file. Also count the number of columns that is exported.
Is there a way to do that within a dts package?

I would like to count rows by grouping of companys. So for one company when the report display the company employee they are associated a number. Example:
Company: Xrite
User: Tom Smith
User # 1
User: Jane Doe
User # 2
Company: Xwrong
User: George Green
User # 1
User: Mary Jane
User #2
I found the function RowNumber(). This function used as follows RowNumber(Nothing) Returns a row number for each record of the table instead of by company name (which is the group by).
Is there a way to use this function RowNumber() or any way in SRS to get the results I'm looking for?

How do I write a query to give me the total records in databaseA.tableA divided by the total records in databaseB.tableA
This is what I have so far:DECLARE @today as datetime
DECLARE @past as datetime
/* set the dates */
set @today = getdate()
set @past = getdate() - 3 /* Go back 3 days */
/* create temp table for holding total cases*/
CREATE TABLE #CaseTotalCount
(
TotalCount int
)
/**/
CREATE TABLE #FlashCycleCount
(
FlashCount int
)
/**/
INSERT INTO #CaseTotalCount (TotalCount)
SELECT COUNT (DataBaseA.dbo.tblProcedureData.CaseID) as TotalCount
FROM DataBaseA.dbo.tblProcedureData
WHERE DataBaseA.dbo.tblProcedureData.Date < @today AND DataBaseA.dbo.tblProcedureData.Date > @past
/**/
INSERT INTO #FlashCycleCount (FlashCount)
SELECT COUNT (DataBaseB.dbo.tblFlashLog.FlashLogID) AS FlashCount
FROM DataBaseB.dbo.tblFlashLog
WHERE DataBaseB.dbo.tblFlashLog.LoadDate < @today AND DataBaseB.dbo.tblFlashLog.LoadDate > @past
/*function call*/
SELECT dbo.percentage(#FlashCycleCount.FlashCount, #PeriOpTotalCount.TotalCount)
FROM #FlashCycleCount
JOIN #PeriopTotalCount
ON #PeriOpTotalCount.TotalCount != 0 This works but when I try to bind this to a formview a get nothing. any ides?

It's not working correctlly. Any ideas?

I have been assigned to fix a script which i did not write and that is not in SQL, but calls to SQL to get it's results.
It reads from a payroll table in SQL with 943 total records (of which about 280 are active employees).
When i run the script, i receive a series of errors listing the field that the error is in (ie: Badge or PayRule) and the record # causing the error.
My problem is that the 1st record # that returns an error is #946. I get a total of 45 records that generate errors of this sort. (ie: #946-957 Badge, 1154-1159 Badge, 1482-1497 PayRule, 1562-1568 Badge, 2083-2086 PayRule).
IF i can figure out which employee those records belong to I will have a much better chance of finding the cause of the errors and correcting them.
When it gives a record #, i always thought it was the row in the table that was referred to, but since the record #'s i am receiving are larger than the number of rows in the table, i am utterly confused!
So...i guess my question is, how do I count the records if not by row?
thanks in advance, and i hope this makes sense!

I am currently using this SQL code to capture some records over the last 2 months and it has been working great. I am now being asked if I can change this code with specifications:
1) Scan the records in the system until the count (*) as Volume reaches 30 because they prefer that as a denominator when figuring an average
2) Only run the scan for a maximum of 6 months.
So, there will most likely be some records that do not reach a volume number of 30 in this date range. In this instance we will just take the maximum volume number reached at 6 months.
So, how can I write this so it will build the file each time a record has reached the maximum of 30 and keep scanning back until we reach 6 months? If someone could lead me in the right direction on the proper order of the methodology in my code to accomplish these results it would be greatly appreciated. Desperate!

Here's a little sql 2005 script I wrote:
1. Start by running this script....
declare @x int
select @x = 1
while ( @x < 75000)
begin
insert into myTesttable values (@x)
Select @x = @x + 1
end
2. While the script is still running, I want to know how many records are in the table. From the same query window as the script, I have run both of the following statements.
select count(*) from mytesttable
witn (nolock)
select count(*) from mytesttable
witn (tablock)
Instead of getting the answer immediately, they run only after the original script has completed. They seem to be "blocked". How can I get a near realtime count of the number of records in this table while the script populates the table?
