SQL Count Records Based On 2 Columns

Oct 15, 2007

Newbie alrt...

I am trying to create an asp page that will update an Access 2000 database. I need to update records if the user exists and create a new record if the user does not exist. Most of the variables are pulled from a separate "post" form.

I am using 2 pieces of info to find duplicates, as employee numbers can be assigned to multiple employees. Right now I have the page check for a duplicate employee id number then check for a duplicate last name. Unfortunately it is running each check separately, so if the last name is duplicated anywhere, it is sending a duplicated value.


here is the chunk of code in question... all RF_variables are request.form variables


cnt="SELECT COUNT(emp_id) AS Xnum FROM " & RF_course
cnt=cnt & " WHERE emp_id='" & RF_emp_id & "'"
set again=conn.Execute(cnt)
dup=again("Xnum")


if dup>=1 then
cnt="SELECT COUNT(lname) AS Xnum FROM " & RF_course
cnt=cnt & " WHERE lname='" & RF_lname & "'"
set again=conn.Execute(cnt)
dupl=again("Xnum")

if dupl=1 then
upd="UPDATE " & RF_course & " SET "
upd=upd & "section" & RF_section & "='" & RF_score & "'"
upd=upd & " WHERE emp_id='" & RF_emp_id & "'"
upd=upd & " AND lname='" & RF_lname & "'"
on error resume next
conn.Execute upd
else
ins="INSERT INTO " & RF_course
ins=ins & " (lname,fname,emp_id,cname,"
ins=ins & "section" & RF_section & ")"
ins=ins & " VALUES "
ins=ins & "('" & RF_lname & "',"
ins=ins & "'" & RF_fname & "',"
ins=ins & "'" & RF_emp_id & "',"
ins=ins & "'" & RF_cname & "',"
ins=ins & "'" & RF_score & "')"
on error resume next
conn.Execute ins
end if
else
ins="INSERT INTO " & RF_course
ins=ins & " (lname,fname,emp_id,cname,"
ins=ins & "section" & RF_section & ")"
ins=ins & " VALUES "
ins=ins & "('" & RF_lname & "',"
ins=ins & "'" & RF_fname & "',"
ins=ins & "'" & RF_emp_id & "',"
ins=ins & "'" & RF_cname & "',"
ins=ins & "'" & RF_score & "')"
on error resume next
conn.Execute ins
end if




Hopefully this is understandable.
If anyone can offer any help I would greatly appreciate it.

Query To Count # Records In Db Based On Foreign Key

Mar 14, 2008

My SQL is very basic.  How do I create a query that will accept a parameter, an integer, and based on the integer, locate all the matches in a db?
 SELECT     COUNT(*) AS Expr1, tblArticle.ArticleIDFROM         tblArticle INNER JOIN                      tblArticleCategory ON tblArticle.ArticleCatID = tblArticleCategory.ACategoryIDGROUP BY tblArticle.ArticleID
This isn't setting up the query to request a parameter.What am I doing wrong here? I"m trying to get the total number of articles for a particular category ID.

Calculated Columns Based On Multiple Columns?

Aug 12, 2014

MS SQL 2008 R2

I have the following effectively random numbers in a table:

n1,n2,n3,n4,SCORE
1,2,5,9,i
5,20,22,25,i
6,10,12,20,i

I'd like to generate the calculated column SCORE based on various scenarios in the other columns. eg.

if n1<10 and n2<10 then i=i + 1
if n4-n3=1 then i=i + 1
if more than 2 consecutive numbers then i=i + 1

So, I need to build the score. I've tried the procedure below and it works as a pass or fail but is too limiting. I'd like something that increments the variable @test1.

declare @test1 int
set @test1=0
select top 10 n1,n2,n3,n4,n5,n6,
case when (
n1=2 and
n2>5
)
then @test1+1
else @test1
end as t2

Conditional Sum Based On Count

Oct 15, 2013

In the database, there is Date, Store#, Item#, and %Total Sales. In some cases, the same item# for the same date may be given more than one value for '% of Total Sales'. (For some reason this is a valid business scenario that happens rarely, but it happens.)

In that situation only, the requirement is to sum the two values together into one line. So if Item# 123 has a line with a value of .05%, and another line with a value of .08%, I need to sum those two values into one line for Item #123 that has a %Total of .13%. ONLY when an item has more than one percentage assigned, those percentages should be summed. Otherwise, if an item# has only one percentage value assigned, we just want to see that value.

Basically, I would like to implement logic that would work like this:

SELECT Date, Store#, Item#,
CASE WHEN Count(%Total Sales) >1 THEN Sum(%Total Sales)
ELSE %Total Sales
END

FROM (some tables and joins)
GROUP BY Date, Store#, Item#

However, I'm not sure how to craft it so that I don't get a syntax error (this query produces errors).

Alphabetical Value Based Of Count?

Mar 6, 2014

there is another way to get the alphabetical value for a number other than using a case statement?

example:

Count = 1 That's = A
Count = 5 That's = E
Count = 8 That's = H

and so on I know a case could do this but wondering if there is a nice function or simple statement that would do this on the fly?

Questions About Memory Based Bulk Copy Operation(InsertRow Count,array Insert Directly,set Memory Based Bulk Copy Option)

Feb 15, 2007

Hi~, I have 3 questions about memory based bulk copy.

1. What is the limitation count of IRowsetFastLoad::InsertRow() method before IRowsetFastLoad::Commit(true)?
For example, how much insert row at below sample?(the max value of nCount)
for(i=0 ; i<nCount ; i++)
{
pIFastLoad->InsertRow(hAccessor, (void*)(&BulkData));
}

2. In above code sample, isn't there method of inserting prepared array at once directly(BulkData array, not for loop)

3. In OLE DB memory based bulk copy, what is the equivalent of below's T-SQL bulk copy option ?
BULK INSERT database_name.schema_name.table_name FROM 'data_file' WITH (ROWS_PER_BATCH = rows_per_batch, TABLOCK);

-------------------------------------------------------
My solution is like this. Is it correct?

// CoCreateInstance(...);
// Data source
// Create session

m_TableID.uName.pwszName = m_wszTableName;
m_TableID.eKind = DBKIND_NAME;

DBPROP rgProps[1];
DBPROPSET PropSet[1];

rgProps[0].dwOptions = DBPROPOPTIONS_REQUIRED;
rgProps[0].colid = DB_NULLID;
rgProps[0].vValue.vt = VT_BSTR;
rgProps[0].dwPropertyID = SSPROP_FASTLOADOPTIONS;
rgProps[0].vValue.bstrVal = L"ROWS_PER_BATCH = 10000,TABLOCK";

PropSet[0].rgProperties = rgProps;
PropSet[0].cProperties = 1;
PropSet[0].guidPropertySet = DBPROPSET_SQLSERVERROWSET;

if(m_pIOpenRowset)

MDX - Select Count Based On Two Different Dimensions

May 19, 2008

I have a fact table with a create time dimension and an expiration time dimension. I'd like to have a calculated member that would compare the (count for create time) / (count with that expiration time). I already have these counts as measures.

I would be able to put the create time dimension in the "row fields" area, and see the ratio (calculated above)
over the different create time periods.

Can someone point me in the right direction on how I would create that kind of calculated member? What would the MDX look like?

Thanks for your help

How To Count Cases For Different Groups Based On Different Criteria

Apr 25, 2008



Hello,

I need to create a query that will count new cases based on the create date(create_date) and criteria for the groups(The only way to distinguish between the 2 major groups mts and bnb is area!= 'bnb" because everything else is MTS). The sample report I need to create below shows how it needs to be counted weekly, for a 4 month period, for the groups under MTS and BNB. The totals and grand totals can be achieved in the report tool. I want to create variables for the new cases (mts_newcases_sales, mts_newcases_salesd, bnb_newcases_salesd etc)

Ex. MTS sales : (status = 'Calculated' OR status = 'REJECTED') and errorsource != 'marketing' and accountns is null and area != 'BNB'(everything else is MTS)

MTS salesd ; Credit >= '1001' and (status = 'REJECTEDV' or status = 'ACCEPTEDS') and errorsource != 'marketing' and accountnr is null

BNB creditr: Credit < 101 and (status = 'SUBMITTED' OR status = 'REJECTEDS' OR status = 'REJECTEDA' OR STATUS = 'ACCEPTEDC')

Trigger To Update Table Based On COUNT Of Column

Sep 26, 2007

Hello again,

I'm hoping someone can help with with a task I've been given. I need to write a trigger which will act effectively as a method of automatically distributing of incoming call ticket records. See DDL below for creation of the Assignment table, which holds information on the call ticket workload.





Code Snippet
CREATE TABLE #Assignment
(CallID INT IDENTITY(1500,1) PRIMARY KEY,
AssignmentGroup VARCHAR(25),
Assignee VARCHAR(25)
)
GO
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Jim Smith')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('PC Support', 'Donald Duck')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Joe Bloggs')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Joe Bloggs')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('Service Desk', 'Joe Bloggs')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('PC Support', 'Donald Duck')
INSERT #Assignment (AssignmentGroup, Assignee)
VALUES ('PC Support', 'Mickey Mouse')

GO

SELECT COUNT(CallID) AS [Total Calls], AssignmentGroup, Assignee
FROM #Assignment
GROUP BY AssignmentGroup, Assignee
ORDER BY COUNT(CallID) DESC , AssignmentGroup, Assignee






What I need to do is write a trigger for on INSERT to automatically update the Assignee column with the name of the person who currently has the least active calls. For example, using the data above, the next PC Support call will go to Mickey Mouse, and the next two Service Desk calls will go to Jim Smith.


So, the logic for the trigger would be

UPDATE #Assignment
SET Assignee = (SELECT Assignee FROM #Assignment WHERE COUNT(CallID) = MIN(COUNT(CallID))


But that's only the logic, and obviously it doesn't work with the syntax being nothing like correct.

Does any one have an idea or pointers as to how I should go about this?

Grateful for any advice, thanks
matt

Help With Count Records

 I'm wondering if you guys can help me with a problem to count every record in a table; however, I must match this table with another table to get the category names.  I have tried this SQL statement in the SQL Express and it works very great.  
SELECT aspnet_Category.CategoryName, COUNT(*) AS Expr1FROM aspnet_Category INNER JOINaspnet_resources ON aspnet_Category.ApplicationID = aspnet_resources.ApplicationId AND aspnet_Category.CategoryID = aspnet_resources.CategoryIDGROUP BY aspnet_Category.CategoryNameORDER BY aspnet_Category.CategoryName
However, when I tried to put this into my code, it gives me a error. <System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Select, True)> _Function GetDataByCount_CategoryID() As CategoryDataTableGetDataByCount_CategoryID = Adapter.GetDataByCount_CategoryIDEnd FunctionFailed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
Can you please help me to fix this error?

Count The Records

Mar 5, 2004

I need to export records to a text file and simply index them. i.e. in the pipe delimited file I need a column with the ordinal value of each row.
Example:

1|"Jane Doe"|"23 Western ave"|...
2|"Jamie Delom"|"5 East Street|...
3|"Nat Girshon"|"5678 Main Street|...

.

Would anyone be able to tell me how I could build this within the SQL query without creating a physical table and using IDENTITY functions?

Dim ConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source='G:Aco ProntoBSCBSC_v1.mdb'"Dim Con As New OleDbConnection(ConnString)
Dim Cmd As New OleDbCommand("SELECT COUNT(*) AS Expr1 FROM Metricas", Con)Dim reader As OleDbDataReader
Con.Open()
reader = Cmd.ExecuteReader()Dim NumMetr As Integer = Val(reader("Expr1"))
reader.Close()
Con.Close()
 
I am getting an error that that's no data in the table.
Any suggestions?

5 FROM Table3 AS e JOIN Table3 AS m
6 ON e.Members_Sponsor = m.Members_ID
7 WHERE (e.Members_Sponsor = m.Members_ID)) AS TotalRecords
8 FROM Table1 INNER JOIN
9 Table2 ON Table1.UserId = Table2.UserId INNER JOIN
10 Table3 ON Table2.UserId = Table3.UserID
11 WHERE (Table3.Members_Sponsor = @UserId)Basicly what I am trying to do is get all members that belong to a certain manager along with those members count total of members they have below them.The code above is giving me the count of the first member only, not different counts for each member.Hope you understand what I am trying to say and do here. Hope someone can help me out cause this hase been driving me crazy for a few days now.
