Loop Through Resultset, Inserting Into Existng Tbl
May 27, 2008
Hello! quick question.
Say I have a table, and I select the primary key as follows:
select fID from findings;
how can I loop through that resultset and execute the following insert at each iteration:
insert into owners (fID, uID) values (@curFID, 273);
where @curFID is the current record from the resultset? I've done some playing with while loops, however the tutorials I found were fairly basic and only provided examples using static loop controls. any help is appreciated!

Hi,
I have made some stored procedures to check if a user is involved with a certain record. basically every stored procedure contains the following logic.
example spCheckClientRelated:
select @res = count(*) from client_role where client_id = @cid and employee_id = @eid
if (@res = 0)
begin
... next select
end
if (@res = 0)
begin
... next select
end
....
return @res
end
so far so good. But the final check in CheckClientRelated tests if a user is related to one of the sales projects for that client.
I allready have the spCheckSalesProjectRelated that returns 1 or 0 similar to the example above
so I want to find an efficient method that selects all the sales_project_id 's from the sales_project table where client_id = @cid (i use offcourse select @sid = sales_project_id from sales_project where client_id = @cid at the moment)
And then I have to execute the spCheckSalesProjectRelated method for each @sid and @eid. This if offcourse where my problem is located. I don't know how to do a fast check for every selected @sid, until spCheckSalesProjectRelated returns 1
As you probably can determine from my question, sql is not really my domain, and I'm certainly not an expert, but I don't mind reading or looking up some stuff, so even a clue or a direction to look in would be most appreciated
thx in advance.

Hi friends, I've been stumped on this for almost a week now. Everything works in the stored procedure code below except for the 'INSERT INTO @Uppdates' block of code. I have a SQL Analyzer test driver and when the code gets to the SELECT statement below the INSERT INTO @Updates line the value of the select line is displayed on the screen and nothing gets written to @Updates. I hope I'm being clear about this. Any ideas? IF @Edit=1 AND LEN(@Changes) > 0

I am creating a simple SSRS table report through Report Builder. My dataset is looking for the stored procedure . When I execute the Stored procedure through SSMS I get resutset for certain parameters. I execute the dataset  (Store procedure) through query designer in dataset properties and I get results back. But when I try to run the report and see the preview, I do not get any results displayed. I been looking on the same issue form last 3-4 days and have not found any clue.
Following is the stored procedure I am using. Also I am passing multivalued parameter through report as well, and I am using spilt function to seperate the libraryid I am reading from parameter values. This works fine. I have similar kind of four other reports and with different stored procedure which exactly follow the same method , like multivalue parameters and other criteria are also very similar. All other reports works just fine.. This perticular report has issue for displying results, following is the stored procedure I am usingÂ
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

Is there a way to insert multiple records into a database table when you're just given "count" of the number of rows you want? I want to do this in ONE insert statment, so I don't want a solution that loops round doing 100 inserts - that would be too inefficient.
For example, suppose I want to create 100 card records starting it card number '1234000012340000'. Something like this ...
declare @card_start dec(16)
set @card_start = '1234000012340000'
declare @card_count int
set @card_count = 100
drop table card_table
create table card_table (
card_number dec(16),
activated char default 'N'
)
insert into card_table
select
... ???? ....
But WITHOUT using a while-loop (or any other kind of loop). I'm looking for fast and efficient code! Thanks.

I have a foreach loop that is supposed to loop through a recordset, however it doesn't loop. It just repeats the same row, row after row.
I would like to look into the recordset variable but I can't because it is a COM object and the ADODB namespace is not available in the script task.
Any solution to this? anyone experienced anything similar

I have a table called Tbltimes in an access database that consists of the following fields:
empnum, empname, Tin, Tout, Thrs
what I would like to do is populate a grid view the a select statement that does the following.
display each empname and empnum in a gridview returning only unique values. this part is easy enough. in addition to these values i would also like to count up all the Thrs for each empname and display that sum in the gridview as well. Below is a little better picture of what I€™m trying to accomplish.
Tbltimes
|empnum | empname | Tin | Tout | Thrs |
| 1 | john | 2:00PM | 3:00PM |1hr |
| 1 | john | 2:00PM | 3:00PM | 1hr |
| 2 | joe | 1:00PM | 6:00PM | 5hr |
GridView1
| 1 | John | 2hrs |
| 2 | Joe | 5hrs |
im using VWD 2005 for this project and im at a loss as to how to accomplish these results. if someone could just point me in the right direction i could find some material and do the reading.

How much performance hit should I expect to use FOR XML to generate XML string directly from SQL Server 2000? I like this approach because it is simple and easy. However, others told me that it has a big performance hit. They prefer to use a COM+ component to create XML string from a Resultset. Any suggestions? Thanks.

Hi,I have 3 tables as follow :Kanji :kanji_id....References :ref_id....KanjiRefskref_idkanjikref_idrefkref_value....So, there is a many-to-many relationship between Kanjis and References(one kanji may have more than one reference type, and a reference typemay be set to more than one kanji).For example, one kanji may have the value 'abc' for reference type #1,and the value 'def' for reference type #2, another kanji may also havethe reference type #1, but have instead the value '123' and so on...I have two questions :1) How to get all kanjis that do NOT have the reference #3 (ref_id = 3)within their list of references?2) How to get the value of all the kanjis that have the reference #3,but still get other kanjis that do not have the reference #3...forexample, if I had 3 kanjis, with the two first having values 'abc' and'def' for reference #3, and the last one having no reference #3, I'dlike to get that resultset :kanji_id kref_value1 'abc'2 'def'3 NULLI manage to get all the kanjis that have reference # 3 with thefollowing query :SELECT kanji_id, kref_valueFROM Kanjis INNER JOIN kanjiRefs ON kref_idkanji = kanji_idWHERE kref_idref = 3however, this obviously does not include kanjis having no reference#3...any help would be greatly appreciated, thanks! :)ibiza

I have a search query on my page. However, since the resultset may be very large, I want to retreive only those results that are currently shown on the gridview page.Often a user won't browse through more than a couple of pages, so it's b-*** to send all the records to the client.I know that with a sp you can define that you want to retrieve the first or second x records, but I want to do this with SQL...is that possible?

I am trying to write a select statement that will return the values of two columns from two different tables in the same statement. I believe the join word needs to be used somewhere, but I am having difficulty with it.
Table1 (table name)
Column1 (column name)

a
b
Table2 (table name)
Column2 (column name)

c
d
results should be:
a,c

Hi,This is what I want to do. For a data acquisition query, if conditionA is met, set weight to 1, else if condition B is met, set weight to 2etc.Is this possible? I thought about using CASE function but to noavail.Using the classical Northwind db as target db, and its employees tableas target table, if [note] column contains 'BA', then I want to setweight to 1, else if it contains 'BTS', then I want to set weight to 2etc. Weight or the like is an auxillary artificially created column.Something likeDECLARE @col intselect firstname, lastname, @col =(CASE noteswhen '%BA%' then 1when '%BTS%' then 2else 0END as aiCOL)-- and I'd like to alias @col as aiCOL or whateverfrom employeeswhere notes LIKE'%BA%'ORnotes LIKE '%BTS%'failed.Thanks.

According to the BOL documenation of the ExecuteSQLTask you can populate a variable with a resultset. I specified a variable of type 'Object' and followed the instructions and everything is fine.
Now I have TWO issues.
1) I want to filter some unwanted rows from this variable and add into another recodset. For filtering i am using foreach loop and putting condition on variable. It works fine till here, but how to update another 'Object' type variable.
2) How to make the result set as source in a data flow task. I want the filtered result set to become source in a data flow
Thanks

I am using the SQL Server 2005 JDBC driver. I need to write a piece of code that makes use of the streaming ResultSet. That is as soon as I get the first row, a worker thread should be able to begin processing on it without waiting for the second row to arrive. When the second row arrives, the second worker thread should start processing on this new row without waiting for the third row to arrive and so on. Usually, with a ResultSet, I need to wait for all the rows to arrive first before I can start navigating the rows in the ResultSet. But in my code, I need to start navigating the ResultSet even as more rows are pouring in from the DBServer. How can I do that? Any pointers in this direction will be helpful. Further, I want to know will setfetchsize be of any help here? If I set the setfetchsize value to 1, does that mean that as soon as I get the first row, I can start working on this row of the resultset(viz start navigating the ResultSet) without waiting for the second row to arrive in the ResultSet?

Hi,
I have used Red Gates SQL bundle to make an identical db on sql2005 express from sql 2000. When i run my query against the sql2000 i get what I want, but when i run it against the sql2005, i get nothing.
Anyone got any suggestions to why?
web.config:
<!-- <add name="TPLConnectionString" connectionString="Data Source=[SQL2000],1433;Network Library=DBMSSOCN;Initial Catalog=TPL;User ID=??????;Password=????????;"
providerName="System.Data.SqlClient" />
-->
<add name="TPLConnectionString" connectionString="Data Source=[SQL2005]\SQLEXPRESS,1433;Integrated Security=true;Network Library=DBMSSOCN;Initial Catalog=TPL;User ID=?????;Password=???????;"
providerName="System.Data.SqlClient" />
default.aspx.cs
dbConnection.Open();
String ISPQuery = "SELECT STATEMENT";
SqlCommand command = new SqlCommand(ISPQuery, dbConnection);
SqlDataReader reader = command.ExecuteReader();
Please help!!!
Best regards

I have a sp: mysp_getstuff it contains the following:SELECT Adress,City FROM tblUserData WHERE UserName='john'as you can see it returns 2 columns.I also have another SP: mysp_GetNr. This sp returns an integer.I want to call mysp_getnr from mysp_getstuff and add the result to the 2 columns in a column named 'Number'So the resultset from mysp_getstuff should be:Adress, City, Number (in which the number column contains the result from mysp_GetNr)How can I do that?

Hi,
I am having some problems exporting to Excel using SQL 7.
I have a DTS package which runs a query that returns one value and pumps the data to an Excel spreadsheet. Everything is working except the data is not populating the correct cell in the spreadsheet. How can I control which cell SQL pumps the data to?
Thanks.

Hello all,
I'm trying to number rows in a resultset by a grouping.
e.g. if my data looks like this:
personname persondata
----------- -----------------
person1 data
person1 more data
person1 other data
person2 stuff
person2 more stuff
person2 even more stuff
person2 lots of stuff
person2 last bit of stuff
person3 info
person3 more info
I want it to return this, with x as a sub-numbered value (like an identity for each grouping):
x personname persondata
-- ----------- -----------------
1 person1 data
2 person1 more data
3 person1 other data
1 person2 stuff
2 person2 more stuff
3 person2 even more stuff
4 person2 lots of stuff
5 person2 last bit of stuff
1 person3 info
2 person3 more info
Any ideas?
Thanks,
Dan

Hi,
I am trying to do a join which involves more than 3 tables. One is a parent table and the other two table have 1:n relationship with that parent table.
But duplicate records are being returned in the resultset. How do I eliminate duplicate records?
This is my query.
SELECT table1.* from table1 left outer join table2 on table1.id=table2.id
left outer join table3 on table1.id=table3.id
I tried doing DISTINCT here but with no success.
SQL with distinct clause.
SELECT distinct table1.id, table1.* from table1 left outer join table2 on table1.id=table2.id
left outer join table3 on table1.id=table3.id
This is the error I get:
The text data type cannot be selected as DISTINCT because it is not comparable
Please help.

I have the below CTE that I just can't seem to get to give me the right results. Basically what im trying to do is use the first query to show the "sources" that are involved in each inquiry and the second query to show which of those have became "admissions" the thing is the counts of the sources when the CTESource query is ran alone is different than my query to join the two tables.
Code:
With CTESource(Total, ID, Source, Program) AS
(
SELECT count(Inquiry.ID) as Total, Referral.InquiryID_fk, Source, Inquirer.Program from Referral
Inner Join Inquiry on Inquiry.ID = Referral.InquiryID_fk
Inner Join Inquirer on Inquirer.ID = Inquiry.InquirerID_fk
[code]....
The total inquiries can be higher than the source totals since a source isnt required in the system as well as there does not have to be admissions regardless of inquiry count.

Hello all,
I want to be able to be able to return a resultset from a Stored Procedure.
Something like :
CREATE PROCEDURE LSNOnAJob
@MyJobNo AS INT,@MyLsn VarChar(10) OUTPUT
AS
SELECT @MyLsn = dbo.TSample.ISmpShortCode
FROM dbo.TJob INNER JOIN
dbo.TSample ON dbo.TJob.IJobN = dbo.TSample.IJobN
WHERE (dbo.TJob.IJobN = @MyJobNo)
GO
I pass the IJobN into the Sproc and it should give me a resultset back that contains 5 Ismpshortcode's (which is the resultset I want to pass back to Access XP). But the value that gets returned is the last result from the recordset.
I'm obviously doing something a bit stupid, so any help would be greatly appreicitated.
