Hello,
I currently have a stored procedure that I call multiple times with an ID to return a record. However, in my program, I sometimes need to return several records (for which I have all the IDs) at the same time.
Is there a way I could pass an array of all IDs so I get all the necessary records with just one round-trip to the database?
[EDIT -- Something like this would be ideal:
CREATE PROCEDURE Whatever
(
@param int_array
)
AS
SELECT * FROM Table WHERE ID IN @param]
Any help would be appreciated! Thanks!

Use the IN operator and pass the integer ids as a comma separated string.
Build the entire SQL statement in your application and execute the statement itself instead of calling a stored procedure.
SELECT * FROM Table WHERE ID IN (param1,param2,...)
Hope this helps...

Yes, I have thought of that. But the stored procedure is not just a single SELECT, so it is not as easy. Any other ideas?
Thanks anyway,

I prefer to use OpenXML rather than a comma delimited list. I'm not sure if that helps though - I suspect if you can't use one, you can't use the other ? OpenXML does translate nicely from XML to a table though, so it may be a better idea.

Hello Christian!
Are you talking about the OPENXML[^] T-SQL Function? If yes, I think that could help. I could build a little XML table with all the IDs and get all of the at once.

hi,
I know this may look easy for some,but I need help with it. I have three tables "inhabitants","Payement" and "postponedPayement". I need to select from inhabitants those that didn't pay their loan and store their Ids along with the unpayed period into table "postponedPayement". The table "inhabitant" gathers all the inhabitants of a bulding while "Payement" table gathers all the payement made by an speific inhabitant for a specific month.
I wonder if someone know how I can do it automaticaly by the end of each month using SQL.
thanks in advance
It's not shame to ask if we don't know but it's shame to pretend you know when u don't

From your post I think your table structure looks something like this (I've tried to fill in the gaps with information that seems to fit the description - if this is not the case then a more accurate description would be more helpful)
Inhabitants
-----------
ID
Payment
-------
InhabitantsID (Foreign key join to Inhabitants.ID)
Date
PaymentAmount
PostponedPayment
----------------
InhabitantsID (Foreign key join to Inhabitants.ID)
UnpaidPeriod
Try this query
INSERT INTO PostponedPayment(InhabitantsID, UnpaidPeriod)
SELECT InhabitantsID, COUNT(*) AS UnpaidPeriod
WHERE p.PaymentAmount = 0
GROUP BY InhabitantsID
It will count all the periods unpaid for each inhabitant and insert it in the PostponedPayment table.
Does this help?

thank u Mr Mackay,
my tables look like this
inhabitant
----------
inhabitantId
... info about inhabitant
Appartment
----------
AppartementId
inhabitantId
Amount //the amount that the inhabitant shoul pay monthly
Payement
---------
inhabitantId
AmountPayed //the amount payed is what's paid each month if done
date //date the the paid amount
PostponedPayement
-----------------
InhabitantId
amountdue
Referencedate //the reference of the unpaid month
I need to get the inhabitants that didn't pay for each month and store these in my PostponedPayement table.
for example
Appartement Inhabitant Payement
--------------------| ----------------| ----------------------------
ApptId inhId Amount| InhID | InhaName| inhId |paidAmount|Date
--------------------| ------|---------| -------|----------|---------
177/R1 inh1 150 | inh1 | James | inh1 | 150 |01/08/2005
177/R2 inh2 180 | inh2 | Jone | inh4 | 100 |05/08/2005
177/R3 inh3 150 | inh3 | Greg |
177/R4 inh4 100 | inh4 | mike |
in my PostponedPayment table I need to get this for august payments plus what is left from other months
PostponedPayement
------------------------------
InhabitantId|AmountDue|Refdate|
------------|---------|-------|
inh2 | 180 |08/2005|
inh3 | 150 |08/2005|
inh1 | 150 |06/2005|
I did the following query to get all those who paid and those who didn't :
select Appartement.ApptId, date, Payement.Amount from Appartement left join Payement on Payement.ApptId=Appartement.ApptId
I get the following
---------------------------------
InhabitantId|Amount | date |
------------|---------|----------|
inh1 | 150 |01/08/2005|
inh4 | 150 |05/08/2005|
inh2 | Null | null |
inh3 | Null | null |
all I need to pik up are the 2 last values in the example and insert them into PostponedPayment
Hope it's clearer now!excuse my English
But I thank yu very much
Thanks to all those who help and those who try to help

I have a report that will come back as 20 pages.
What the user wants is on the beginning of another unique ID, which causes a new page to be started, to have the page count restart to 1.
So, if I have 3 UniqueIDs for all 20 pages, and the first, IDAA, is 10 pages long, the second, IDBB, is 4 pages long, and the third, IDCC, is 6 pages long, then the page numbering would be as:
1-10 for IDAA
1-4 for IDBB
1-6 for IDCC
I've been told to set a cursor in a SP that determines what page I'm on and then passses this to the result set as a column. This is then set in a group to control page breaks. How could I do this? I'm not very familiar with SPROC cursors.
I know how to do this scenario in Crystal Reports, but am trying to figure it out here with either a page count formula, or some type of distinct count().
Thanks!

This is what I've tried so far, but it resets on every page.
So, each page is 1 even if the Unique ID spans 2-3 pages.
I only need it to reset on a new field grouping of the list object.
Here's the VB code for the report:
Shared offset As Integer
Public Function GetPN(reset As Boolean, pagenumber As Integer) As Integer
If reset
offset = pagenumber - 1
End If
Return pagenumber - offset
End Function
***************************
In the header, I have a textbox named "tag"
In the footer, I've got the following expression:
="Unique ID Page: " & Code.GetPN(Not(ReportItems!tag.Value Is Nothing),Globals!PageNumber)
|
|
|
|
|
My fault...I had the textbox "tag" in the page header and not in the list object itself.
It works!
Thanks!

this query is perfect in Ms-Access but its not working in Sql Server
UPDATE EmpDept INNER JOIN clockings ON EmpDept.clockno=clockings.clockno SET clockings.deptid = empDept.deptid;
it shows following error msg.
Incorrect syntax near the keyword 'INNER'.

The basic syntax of UPDATE statement in SQL Server is
UPDATE {table_name | view_name}
SET column_name1 = {expression1 | NULL | DEFAULT | (SELECT)}
[, column_name2 = {expression2 | NULL | DEFAULT | (SELECT)}
[ ,...n ]
WHERE {search_conditions}
Try this.
UPDATE clockings SET clockings.deptid = ( SELECT EmpDept.deptid from EmpDept WHERE clockings.clockno = EmpDept.clockno )
|
|
|
|

I have used UPDATEs with JOINs before, and it works in SQL Server. I believe the SET clause should come before the JOIN, and also, that you need a FROM clause before any JOIN.
Try this:
UPDATE clockings SET clockings.deptid = empDept.deptid
FROM EmpDept
WHERE EmpDept.clockno = clockings.clockno I hope this helps!

I would like to know how to check for 'NO RECORD FOUND' after a Select statement.
I am not sure about 'SQLCODE or SQLSTATE'. Please Help!!

Use COUNT to see if any records are returned.

If this is inside a stored procedure check for
select @@rowcount.
If you want to check this in ADO.NET, then
SqlCommand.ExecuteNonQuery() will return the no of rows selected.

I am trying to prevent duplicate records from being appended to my Access database. What I did was created two tables in Access. The first one "NewResultsTable" is populated with new records. I created a Query in Access "Query1" which appends the first database to the second database. The Table "NewResultsTable" is then cleared of all of its records.
The table "TestResultsTable" has three primary keys:TestDate, TestTime, and SerialNumber. So when I run "Query1" while in Access, if all three of those primary keys are the same as any other three primary keys I will get an error message similar to the following.
"Microsoft Access can't append all the records in the append query
Microsoft Access didn't add (Number of records) to the table due to key violations
To ignore the error and run the query, click Yes"
I click yes the records that aren't duplicates are appended to "TestResultsTable". I wrote a small test program in C# and called the "Query1".
When there where no duplicates the "TestResultsTable" is appended to no problem. When there are duplicates I get the following error.
"The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again."
I don't know how to tell Access to continue and run the query. How can I do this? Or would it be easier to write a SQL statement? What would the SQL statement be that would do this same thing?
Thanks to anyone who can help.

Why don't you write a query that doesn't cause the error ? Ideally you should not send duplicate data to the database, but your proc for doing an insert should first check if the unique ID exists, and perhaps if it does, do an update instead.

Hi,
Need some help. Say I have 5 rows in my table and I filled in 4 rows and submit it, now I want to add data to the 5th row by using an update statement.
It looks like this:
MainID | EntryDate | TechName | Software | Application | Problem | Solution
The Main ID is an int and the entrydate is a datetime. I fill in a form to add a problem. Now someone goes and click on the entry in a datagrid and then adds a solution.
Thanks for the HELP!!!

You can iterate over the datagrid to find out which rows are changed, then you just fire an update statement for each row, or use OPENXML or something like that to pass all the rows in for one transaction.

Good Evening,
I'm working with C# code which presents a dataset with an id and name column, it also has an added expression column to concatentate the two as follows:
DataColumn aggregateCol = new DataColumn();
aggregateCol.DataType = System.Type.GetType("System.String");
aggregateCol.ColumnName = "strConcat";
aggregateCol.Expression = "Convert(id, System.String) + ' ' + name";
concatTable.Columns.Add(aggregateCol);
concatTable is passed to this code as: this.downtimeData.Tables["Equipment"]
to Test the result I printed the contents of the Datatable after it had been merged with a populated dataset as follows:
this.downtimeData.Merge(downtimeData);
System.Diagnostics.Debug.WriteLine(this.downtimeData.Tables["Equipment"].Rows.Count);
System.Diagnostics.Debug.WriteLine(this.downtimeData.Tables["Equipment"].Rows[0].ItemArray[0] + " " +
this.downtimeData.Tables["Equipment"].Rows[0].ItemArray[1] + " " +
this.downtimeData.Tables["Equipment"].Rows[0].ItemArray[2]);
And the perplexing print out reads:
3
1 spoon
 Why does the strConcat field not contain a value?
Thanks in advance
