SELECT COUNT (*) FROM Dbo.myTable WHERE MyName ='Bill'
Aug 25, 2006
Hi.
Am struggling when trying to convert an old CMS from ASP 3 to ASP.NET 2.0
How can I use a SELECT COUNT (*) statement as described in the heading using SQL connection to a MS SQL Server 2005
What I want to do is to return the occurencies of a name in a table field programatically for further processing.
So...when I have discovered that I had one or more occurencies, I will create a new query to get other data from the table.
Would appreciate an answer fast as I can't seem to find info in the documentation on MSDN (hard to find a tree in the forest)
I want to use ssis to export data from relational tables in sql server 2005 and import them into an xml column in sql server 2005.
Any suggestions for the best way to do this.
I created an datareader source using adventure works with the sql command "SELECT * FROM purchasing.vendor FOR XML RAW"
I then created a sql server destination with and mapped the output from above to an xml column.
I get the following error
Error: 0xC0202009 at Data Flow Task, SQL Server Destination [596]: An OLE DB error has occurred. Error code: 0x80040E14.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E14 Description: "XML parsing: line 1, character 2033, unexpected end of input".
Is there a better way to attack this? I'd prefer not to need to send to the file system, etc.
For some reasons I need to access the same field of the same table twice in a query, and each give out a diferrent valueLike this:"SELECT myTable.id, myTable1.id as subID FROM myTable INNER JOIN ... INNER JOIN myTable as myTable1 ..."The question is, when I write it as myTable as myTable1 will it affect the query performance if myTable is a large table? will it create another so big copy of myTable? or I should create a view like "CREATE VIEW myTable1 AS SELECT id FROM myTable" to reduce the side of myTable1?Thank you.
I was wondering how Fuzzy Grouping deals with and handles first name similarities. Is there a way to configure it so that Anthony = Tony, Bill = William, etc€¦? I created a simple package with several rows containing similar first names and ran the fuzzy grouping on the first name column. I received only one possible duplicate of Will = William which was at 56%. I lowered the threshold down to 1% and still only one match.
Now I understand and appreciate the reasons for this but was wondering if this type of situation was considered and a way of dealing with it is available.
What does Invalid object name "MyTable" mean? I checked the table and column names. They are both correct. Will the error mean something else, e.g. wrong data type, or no data?

I am using three tables in this query, one is events_detail, one is events_summary, the third if gifts. The original select statement counted the number of ids (event_details.id_number) that appear per event_name (event_summary.event_name).
Now, I would like to add in another column that counts the number of IDs that gave a gift who attended an event that were also listed in the event_ details table. So far I have come up with the following. My main issue is linking the subquery properly back to the main query. how to count in the sub-query and have the result placed within the groups results in the main query.
SELECT es.event_name, es.event_id, COUNT(ed.id_number) Number_Attendees, ( SELECT COUNT(gifts.donor_id) AS Count2 FROM gifts WHERE gifts.donor_id = ed.id_number ) subquery2
Hello, I would like to count the number of items in a table.

Can anyone help me with this? Thanks

I am having trouble creating a query which will list schools with ALL their Admission = Null. For example, if at least one record is not null, don't list it, but as long as ALL the records have Admission = Null, then list it. I hope that's clear. Thanks!

Hello,We have a database filled with local restaurants for a directory. What I'm trying to do is display a list of all the cuisines and the number of restaurants who serve that type of cuisine in parentheses. It should look like the example below:American (12)Chinese (3)Italian (5)...Here are the tables with only the relevant columns: restaurants---------------...cuisine_id... cuisines-----------cuisine_idcuisine_name... So basically I want to pull all the names from the cuisines table and then the restaurant count from the restaurants table. The only way I can think of doing that is to grab the cuisine_ids, put them in an array and then use that in a loop to get the count from the restaurants table. That's not very elegant. Is there a better way?Thank you

Here's what I'm trying to do: 1. Output each country in one column 2. Output the number of subscriptions made from a member of that country where tblOrders.orderTypeID = 3 and tblSubscriptionPacks.TypeID = 1 in the next column 3. Output the number of subscriptions made from a member of that country where tblOrders.orderTypeID = 3 and tblSubscriptionPacks.TypeID = 2 in the next column
My problem was that I was doing joins, and I was somehow ending up with orders where the OrderTypeID was NOT equal to 3, even though I declared it specifically in the WHERE clause.
I have two tables. Houses and Guests. The guests are the people who visited the houses tied by the HouseNo.
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.
The Guest table has GuestName and HouseNo. How can I do a select on all houses and then show a column of COUNT(GuestName) for all the guests with the HouseNo matching each row?
I'm trying to create a DTS package that uses CDO to send users an email. I need to create a sql query that counts two columns. I also need to create aliases for these two columns and then reference this in the sendEmail function. I have something that looks like this but I'm getting a DTS error. I think that it's because I'm not using an alias to reference Valid and Invalid. Can someone tell me how to alias the subselect columns correctly?? thanks :)

Could someone assist with getting the count function working correctlyin this example please. I know the count function will return all rowsthat do not have null values, but in this case I want to count all therows except those with a zero sale price, (which are unsold).The table shows works offered for sale by an artist, with a positivefigure under SalePrice indicating a sale, and I want to count thenumber sold by each auction house, and sum the sale price by auctionhouse. The table is as follows:NameSalePriceAuctionDowling12000ChristiesDowling 0ChristiesDowling10000ChristiesDowling 0ChristiesDowling 0ChristiesDowling 6000SothebysDowling 0SothebysDowling 0SothebysDowling 8000SothebysDowling 0SothebysDowling 0SothebysDowling 0SothebysWhen I run this query:SELECT MyTable.Name, Count(MyTable.Name) AS [Number],Sum(MyTable.SalePrice) AS TotalSales, MyTable.AuctionFROM MyTableGROUP BY MyTable.Name, MyTable.AuctionHAVING (((MyTable.Name)="Dowling") AND ((Sum(MyTable.SalePrice))>0));The results are:NameNumberTotalSalesAuctionDowling 5 22000 ChristiesDowling 7 14000 SothebysThe TotalSales is correct, but the Number (Count) is incorrect, as therows with zero were also included. The results should be:NameNumberTotalSalesAuctionDowling 2 22000 ChristiesDowling 2 14000 SothebysHow do I prevent the unsolds (zeros) being counted?Thanks in advance,John Furphy
We have one table have problem when run "select count(*) from table". This is a sql 2000 server. it returned different count everytime when I ran the "select count(*) from table". I used DBCC to check the table and did not find any problems. I can fix it by recreate the table and reimport the data, but the problem come back after we update some data in the table monthly with a stored procedure. Any suggestion?
I found some really helpful code that allows for quick retrieval of select count(*). But am I right in saying that select count(*) can cause locks on the table?
This is the code dbcc updateusage (N'Test') go select count(1) from Testdb go CREATE FUNCTION dbo.udf_Tbl_RowCOUNT (
@sTableName sysname -- Table to retrieve Row Count )
RETURNS INT -- Row count of the table, NULL if not found.
/* * Returns the row count for a table by examining sysindexes. * This function must be run in the same database as the table. * * Common Usage: SELECT dbo.udf_Tbl_RowCOUNT ('')
* Test PRINT 'Test 1 Bad table ' + CASE WHEN SELECT dbo.udf_Tbl_RowCOUNT ('foobar') is NULL THEN 'Worked' ELSE 'Error' END
-- main select WITH Orders AS ( SELECT ROW_Number() OVER(MyDate ASC) RowNo, ** rest o the query *** ) SELECT * FROM Orders WHERE RowNo BETWEEN 100 AND 200 ORDER BY RowNo
--count of records DECLARE @COUNT INT SELECT @COUNT = COUNT(*) FROM ** the same query as above *** RETURN @COUNT
In this case it can happen that when counting records there will be different number of records that it was at time of paging. Also server has to execute this query twice and the query is quite complicated means that takes time.
Is there any better way to get number of rows in the same part of query with paging ?
I have 2 tables, Jobs and Categories.Each job belongs to a category. At present, I am returning all categories as follows:SELECT categoryID, categoryName FROM TCCI_CategoriesWhat I'm trying to do, is also return the number of jobs assigned to each category, so in my web page display, it would show something like this:Engineering(5)Mechanical(10) etc.My db currently has 5 categories, with only one job assigned to a category. I tried the following sub-query, but instead of returning all the categories with their job counts, it just returns the category that has a job assigned to it:SELECT c.categoryID, c.categoryName, COUNT(j.jobID)FROM TCCI_Categories c, (SELECT jobID, categoryID FROM TCCI_Jobs) jWHERE j.categoryID = c.categoryIDGROUP BY c.categoryID, c.categoryName, j.jobIDThis is the output when I run the query:categoryID categoryName Column1 ---------------- ---------------------- ------------------------------32 Engineering 1 How would I fix this?
