So, I ran a query returning just the primary keyset (2 fields make up the primary key) for each row, and it also returns 5,993 rows.

Please do not ask questions like this or post replies like these. If you know, then you reply. It should be authoritive, correct, reliable and functioning.

Otherwise, what is the meaning of posting each persons views / irritation etc.

This is not a place for fights. So, please reply only if you understand and know the things.

Ok, now, can anyone tell me how to extract multiple column values from a single table satisfying a particular condition ? Please help me earliest. My customer is having problem (errors) in the software I gave him.

Is it possible to get the row count from many (1 to 4) tables
including a condition.
Like For Example I want the number of active employees , active departments (employee count from employeemater table and department count from departmentmaster table)

This has to be done using simple query. (not more coding required)

Pinal, how to know the date time, the record inserted into table or record modified.
Table doesn’t have column – datetime.

please any one can help me

Thanks
Kiran

To get the correct answer you have to make the correct question.

If it were me, and I were interviewing prospective DBA’s, I would prefer they know more about querying the data than using the GUI. A better question would have been can you tell me which table (if SQL 2000) or which DMV (SQL 2005 or 2008) contains the row count displayed in the GUI.

Anybody can learn the GUI, but a real DBA knows how to get along without it.

Just my thoughts.

HGH

2 ways I think of

1) sysindexes (may not be accurate)
SELECT
OBJECT_NAME(sysindexes.id) TableName
,ROWS
FROM sysindexes

2) In 2008 SSMS, add in the column “Row Count” for the Tables

but to get most accurate count, I’d still use
SELECT COUNT(1) FROM Table (nolock)

(get-item SQLSERVER:\sql\dbserver\default\Databases\user_database\Tables\dbo.user_table).rowcount

gets the rowcount for table called user_table in database user_database on server dbserver

I know this was an interview question to find out what people know, but when would you ever need to find out the rowcount of a table without using t-sql?

Few cents from my side…

–This is fastest amoung all, output includes some good information including row count information.
select sp_spaceused [table_name]

– If you just want rowcount for all tables/single table in a database,
– for all tables
Select A.name ‘TableName’ , B.rowcnt ‘RowCount’ from sysobjects A, sysindexes B where A.id =b.id and A.type = ‘u’ and indid <2

– for single table
Select A.name ‘TableName’ , B.rowcnt ‘RowCount’ from sysobjects A, sysindexes B where A.id =b.id and indid <2 and A.name = table_name

– The poorest among all. If we have a exclusive lock on that table, this query will be running for ever.
select count(*) from table_name

That aside, as a developer I would have felt compelled to point out a couple of lines of .NET code that could have accessed the DataTable.Rows.Count object as well… either that, or go through SMO. Whether you’d class that as “opening” the table, compared to whatever Management Studio is doing in the background in order to get that RowCount …

Easy to get caught up in the semantics, methinks :-D

Pinal, question for you: *is* Management Studio “opening” the table in the background to get this figure on-demand? Or is the figure a running count that’s stored separately, and updated live whenever the table is updated?

If it’s on-demand, I’d argue that Management Studio is still “opening” the table, in order to get that figure…
