I need help!
My function inserts certain number of rows into dbf with INSERT INTO statement, dbf has 66 fields.
When I insert 983 records it fails with VFP OLE DB Provider error: Variable X is not found, but for less number of rows - aplication doesn't fails.
I think something wrong with my VFP OLE DB Provider. Surfing the Internet didn't help me  (I'have tried to update my provider - didn't help or I did something wrong) .
Did anyone have this issue?
Here is my code:
OleDbConnection oleDbConnection = new OleDbConnection("Provider=vfpoledb;Data Source=" + _tempFolderPath)
string insertCommandText = String.Format("INSERT INTO {0} ({1}) VALUES ({2})",
dataTable.TableName,
columnsList.TrimEnd(','),
arguments.Replace("P", "?,").TrimEnd(','));
int it = 0;
foreach (DataRow dataRow in dataTable.Rows)
{
using (OleDbCommand oleDbCommand = new OleDbCommand(insertCommandText,
oleDbConnection,
oleDbTransaction))
{
for (int i = 0; i < dataRow.ItemArray.Length; i++)
{
if(IsAdditionalSortColumn(dataTable.Columns[i].ColumnName))
continue;
oleDbCommand.Parameters.AddWithValue("@param" + i, dataRow.ItemArray[i]);
}
oleDbCommand.ExecuteNonQuery();
it++;
}
}
}

Hi
I have a general question about SQL server:
I am running a server that needs a very limited number of user connections (max of 5 at a time). So the 5-CAL edition of SQL 2008 Workgroup seems perfect for me. Now, what I need to know is the following: do I actually need to physically install a CAL on each machine/user that will be using the server (by using I mean reading and writing) or does the 5-CAL licence simply mean that only 5 machines/users will be able to log at any one time?
I.e. can 6 or 7 different people use this as long as only 5 of them are connecting simultaneously?
Thanks
Karl

There may not be a LMBTFY yet but try this[^], 4-5th result looks promising

Try adding the length of the varcher2 variable as
OracleParameter = cmdproc.Parameters.Add("ls_tube_batch", OracleDbType.Varchar2, 100)
100 will be the lenght of varchar you have defined in database

In some fields the parameter length mismatch is happening

Hi,
I just added full text searching to a table, and the text in the ProductLongDescription column is:
On the go. For all purpose Industrial and Outdoor purposes. Half Hose. Available in Grey or Navy Blue.
When I use the following statement then the record above is returned:
SELECT ProductID_PK, ProductName, ProductLongDescription
FROM tblProduct
WHERE CONTAINS(ProductLongDescription, 'go');
When I use the following statement then nothing is returned, but you can see that "for" is in the sentence as well:
SELECT ProductID_PK, ProductName, ProductLongDescription
FROM tblProduct
WHERE CONTAINS(ProductLongDescription, 'for');
What am I doing wrong? Please can someone help me?
Thanks
Brendan

Hi Brendan
"a","the","an", "for".. etc are noise words. If you view the Messages can see a information
Informational: The full-text search condition contained noise word(s).
if u execute the same query searching for Outdoor then the query runs properly.
Thanks & Regards

declare @BatchHeader table
(bhid int, status int)
insert into @BatchHeader values (1, 10)
insert into @BatchHeader values (2, 10)
insert into @BatchHeader values (3, 10)
insert into @BatchHeader values (4, 10)
insert into @BatchHeader values (5, 15)
insert into @BatchHeader values (6, 15)
insert into @BatchHeader values (7, 15)
select * from @BatchHeader
declare @BatchHeaderReference table
(parentid int, child int)
insert into @BatchHeaderReference values (1,2)
insert into @BatchHeaderReference values (1,3)
insert into @BatchHeaderReference values (1,4)
insert into @BatchHeaderReference values (1,5)
insert into @BatchHeaderReference values (1,6)
insert into @BatchHeaderReference values (1,7)
select * from @BatchHeaderReference
@BatchHeaderReference.ParentId and Child are the FKs to @BatchHeader.bhid
The output is this:
@BatchHeader
bhid Status
1 10
2 10
3 10
4 10
5 15
6 15
7 15
@BatchHeaderReference
Parentid Child
1 2
1 3
1 4
1 5
1 6
1 7
I want to write a query to fetch unique @BatchHeader rows only if the parent and child have status = 10. So in this case the query shoudnt return any @BatchHeader rows (bcos bhid 5,6,7 have status 15). But if I update the status for bhid=5,6,7 to 10 then the query should return bhid=1.
I tried something like this but it returns bhid=1
Select Distinct bhr.ParentId From @BatchHeaderReference bhr
Join @BatchHeader bh1 with (readpast) on bhr.Child = bh1.bhid
Join @BatchHeader bh2 with (readpast) on bhr.ParentId = bh2.bhid
Where
bh1.Status = 10 -- Child batch status
And bh2.Status = 10 -- Header batch status
Please help.
Thanks,
Joe

I had to go look at this properly IE in TSQL. @BatchHeaderReference joins ALL records to the header record 1, therefore header records 2-7 do not take part in the statement. no link to the @BatchHeaderReference table!

What database are you using, I have never seen readpast

I am using SQL Server as the database. I have copied and pasted the query as-is but for simplicity, I changed the tables to table variables, so you see the (readpast) in the query that fetches rows from a table variable.
I have to achieve this in a single SQL, so cant use any complex logic of additional table variables.
Thanks,
Joe

You missed the point, the problem is in your join. All reference records join to hdr record 1 and are therefore valid.
parentid int (1) = bhid int (1) therefore status will always be 10
@BatchHeaderReference
Parentid Child
1 2
1 3
1 4
1 5
1 6
1 7
Is correct, status 15 never comes into it and the 2-7 are NOT FROM THE HDR table. I think your data structure is screwed, if your status was on the reference table then the filtering would work

I understand, but I cant have a status on the BatchHeaderReference table. This table is just to figureout the parent/child relationship and the status of these should be retained on the BatchHeader table only.
So only if all the header and child rows from HDR table are in status 10 then the query should return the id.
Thanks,
Joe

Change the joins to INNER JOIN and add the filter (=10) on BH2 join rather than the where clause

Thanks for the reply Mycroft Holmes, but no luck.
Tried this
Select Distinct bhr.ParentId From @BatchHeaderReference bhr
Inner Join @BatchHeader bh1 on bhr.ChildId = bh1.id and bh1.Status = 10
Inner Join @BatchHeader bh2 on bhr.ParentId = bh2.id and bh2.Status = 10
And
Select Distinct bhr.ParentId From @BatchHeaderReference bhr
Inner Join @BatchHeader bh1 on bhr.ChildId = bh1.id
Inner Join @BatchHeader bh2 on bhr.ParentId = bh2.id and bh2.Status = 10
Where
bh1.Status = 10
|
|
|
|

Try this
Select *
From @BatchHeaderReference bhr
INNER Join @BatchHeader bh1 on bhr.Child = bh1.bhid
WHERE bhr.child IN (SELECT bhid FROM @BatchHeader WHERE status = 10)

The way I read this problem all of the children must have the status of 10. If the parent has any children without the status ten then it doesn't come back.
This makes it a bear because you have to do something to match all children with all children who have a status of 10 and only return the parent if the children all come back as status 10.
So I'd use a counting mechanism.
select distinct x.parentid
from (
select
bhr.* ,
(select max(bh.status) from @BatchHeader bh where bh.bhid=bhr.child) status,
(select count(*) from @BatchHeaderReference bhr2 where bhr2.parentid=bhr.parentid) cnt,
(select count(*) from @BatchHeaderReference bhr3 inner join @BatchHeader bh3 on bh3.bhid=bhr3.child where bh3.status=10 and bhr3.parentid=bhr.parentid) truecount
from @BatchHeaderReference bhr
) x
where x.cnt=x.truecount
I'm more of an oracle guy but the above will work.
Going from the inside out, which is usually the best way to deal with these problems, you create a count of all children. Then a count of all 'true' children- those with a status of 10. Then you put all of that inside of a wrapper which we call X.
From there we treat X as another table.
If you need to also check to see if the parent has a status of 10 then you just change it to this.
select distinct x.parentid
from (
select
bhr.* ,
(select max(bh.status) from @BatchHeader bh where bh.bhid=bhr.child) status,
(select count(*) from @BatchHeaderReference bhr2 where bhr2.parentid=bhr.parentid) cnt,
(select count(*) from @BatchHeaderReference bhr3 inner join @BatchHeader bh3 on bh3.bhid=bhr3.child where bh3.status=10 and bhr3.parentid=bhr.parentid) truecount,
(select max(bh.status) from @BatchHeader bh where bh.bhid=bhr.parentid) pstatus
from @BatchHeaderReference bhr
) x
where x.cnt=x.truecount
and x.pstatus=10
Here you get the parent status, calling it pstatus, and then just check it at the last stage.
edit: the reason MAX is used is to stop certain errors from creeping in if you have the same value show up but multiple times. If you expect different values for status against a given id then you'd have to take another approach because this would be incorrect.

If I have understood your problem correctly, then try the following query
SELECT BHID 'PARENTID' FROM @BatchHeader BHR1
WHERE BHR1.STATUS = 10
UNION
SELECT PARENTID FROM @BatchHeaderReference BHR
INNER JOIN @BatchHeader BH
ON BH.BHID = BHR.CHILD
AND BH.STATUS = 10
As per the current scenario, the output will be
PARENTID
--------
1
2
3
4
If you update 5 and 7 of @BatchHeader to 10, the output will be
PARENTID
--------
1
2
3
4
5
7
Hope this helps

Hi
I used to use the function SCOPE_IDENTITY() to get the inserted identity, now I need to get the inserted GUID any idea how to do so
Thanks

The minimum of research turns up the first in this list clickety[^] which leads me to believe that GUIDs are a really bad idea.
I have used unique identifiers where databases needed to be merged but there was always an identity field for local processing.

Hi all, am not too experienced with microsoft sql database. I want to use a foreign key e.g mod_data_id, auto generated in a table Data_modification, as a foreign key in another table called modification_copy, such that each time data is inserted in Data_modification table, the mod_data_id will be used to update the modification_copy Tanle.
Plz! help. The code is given below:
Data_Modification (mod_data_id,Patient_ID, Date_Collected, Wrong_Data_Entry_Date, Data_Field, Provider)
Modification_Copy (Data_Mod_ID,mod_data_id, Date_Collected, Data_Attribute, Correct_Data_Value)
Thanks in advance for ur help.

A couple of things:
What you are describing sounds like a trigger, triggers are EVIL as they make support difficult. I would suggest using a stored procedure to do the updating in both tables wrapped in a transaction @@IDENTITY (SCOPE_IDENTITY() is required if you use triggers) will give you the last entered identity field
nedusmile wrote: Data_Modification (mod_data_id,Patient_ID, Date_Collected, Wrong_Data_Entry_Date, Data_Field, Provider)
This is going to drive you (or the person who supports your DB) nuts. Get rid of the unserscores they are sooo 80s.
Data_Modification (ModDataID,PatientID, DateCollected, WrongDataEntryDate, DataField, Provider)
is much more readable IMHO.
Foreign keys define relationships and constraints, they will not cause data to be changed.
I recommend getting a beginners book on database design.
