I have two Tables, 1.Inventory Details Table another one is Inventory Header Table.
Inventory Details Table having a column Card No and inventory Header Table having columns From card No and To Card No.
I want to give relationship between these two tables with Card no. Could you please provide me the Sql Query.
Your help would be greatly appreciated .
Regards

Hi Raju,
We have two way that we can relate to the table either join or quality condition use following syntax/Query for relating two tables
select * from Inventory_Details ID inner join Inventory_Header IH on ID.CardNo between IH.FrmCardno and IH.ToCardNo
or
Select * from Inventory_Details ID ,Inventory_Header IH where ID.CardNo=IH.CardNo OrSelect * from Inventory_Details ID ,Inventory_Header IH where ID.CardNo between IH.FrmCardno and IH.ToCardNo
Hope this will help you

How to join two columns between two tables with different column names

Hi
How i can join 2 columns with different names between the 2 tables.
Can any one please give solution for this.
Thanks
Manu

Hi,
basic understanding of joins:
If you want to join 2 tables there should be matching column w.r.t. data and it's data type. You need not to have same column names in both the tables...
so, find those columns which has got same values..

Cartesian of data from two tables with no matching columns

Hello,
I was wondering – what’s the best way to create a Cartesian of data from two tables with no matching columns in such a way, so that there will be only a single SQL query generated?
I am thinking about something like:
for $COUNTRY in ns0: COUNTRY ()
for $PROD in ns1:PROD()
return <Results>
<COUNTRY> {fn:data($COUNTRY/COUNTRY_NAME)} </COUNTRY>
<PROD> {fn:data($PROD/PROD_NAME)} </PROD>
</Results>
And the expected result is combination of all COUNTRY_NAMEs with all PROD_NAMEs.
What I’ve noticed when checking query plan is that DSP will execute two queries to have the results – one for COUNTRY_NAME and another one for PROD_NAME. Which in general results in not the best performance ;-)
What I’ve noticed also is that when I add something like:
where COUNTRY_NAME != PROD_NAME
everything is ok and there is only one query created (it's red in the Query plan, but still it's ok from my pov). Still it looks to me more like a workaround, not a real best approach. I may be wrong though...
So the question is – what’s the suggested approach for such queries?
Thanks,
Leszek
Edited by xnts at 11/19/2007 10:54 AM

Which in general results in not the best performanceI disagree. Only for two tables with very few rows, would a single sql statement give better performance.
Suppose there are 10,000 rows in each table - the cross-product will result in 100 million rows. Sounds like a bad idea. For this reason, DSP will not push a cross-product to a database. It will get the rows from each table in separate sql statements (retrieving only 20,000 rows) and then produce the cross-product itself.
If you want to execute sql with cross-products, you can create a sql-statement based dataservice. I recommend against doing so.

How to update two columns in two tables?

hi friends
I have two tables linked to each other through SaleNo and SaleDT. their structure as below
Sales Table============
SaleNo int PK auto increment
SaleDT Datetime PK
Qnty decimal
Units decimal
Invoices table
=================InvoiceNo int PK Auto incremented
InvoiceDT Datetime
SaleNo int FK
SaleDT Datetime FK
Note that SaleDT column is NOT assigned with getDate() expression.
1. what I need to do is update the SaleDT column of Sales table and Invoices table with the value '2013-01-31 10:31:55.813', how do I do this without manually breaking the link between the tables?
2. Assume SaleNos 15 to 27 needs update the SaleDT to '2013-06-12 10:31:55.813', how do I do this complex operation where I I have update SaleDt column of two table of SaleNo range from 15 to 27?

else if (MessageBox.Show("Do you want to save changes to AssignedDialyzer.pdf before closing?", "DRRS", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Exclamation) == DialogResult.No)
this.Close();
The above code executes well with no problem at all!
As you can see the file to which i create and save and open my pdf report is
AssignedDialyzer.pdf.
The column headers of table in pdf report from c# windows forms using iTextSharp are
"Reprocessing Date","Patient Name","Dialyzer(Manufacturer,Size)","No.of Reuse","Verification" and
"DialyzerID".
However the problem i am facing is after execution and opening of document is my
column headers in table in pdf report from
c# and datas in it all appear in bold.
I have browsed through net regarding to solve this problem but with no success.
What i want is my pdf report from c# should be similar to following format which i was able to accomplish in vb6,adodb with MS access using iTextSharp.:
Given below is report which i have achieved from vb6,adodb with MS access using iTextSharp
I know that there has to be another way to solve my problem.I have browsed many articles in net regarding exporting sql datas to above format but with no success!
Is there is any another way to solve to my problem on exporting sql datas from c# windows forms using iTextSharp to above format given in the picture/image above?!
If so Then Can anyone tell me what modifications must i do in my c# code given above so that my pdf report from c# windows forms using iTextSharp will look similar to image/picture(pdf report) which i was able to accomplish from
vb6,adodb with ms access using iTextSharp?
I have approached Sound Forge.Net for help but with no success.
I hope anyone/someone truly understands what i am trying to ask!
I know i have to do lot of modifications in my c# code to achieve this level of perfection but i dont know how to do it.
Can anyone help me please! Any help/guidance in solving this problem would be greatly appreciated.
I hope i get a reply in terms of solving this problem.

How to update two tables with trigger

Hi:
how to update two tables with trigger ?
I have two tables :
(1)ASIA
MI number;
(2)ASIA_P
ID number;
When I insert a new value into the asia.MI ,I also can
insert the same value into the asia_p.id field.
I have write a trigger as follows but it does't work.
create or replace trigger MI_TRG
before insert on asia
for each row
declare
seq number;
begin
select MI_SEQ.Nextval into seq from dual;
:new.MI:=seq;
insert into ASIA_PRO(MI_ID)

Why do you say it does not work?

To find matching records across two tables

Hi folks,
I have a question regarding modifying the query. I am trying to compare the data between two tables, there are matching records in two tables, but are not in the same order. How to modify the query so that it finds the matching record between the two tables?
Here is my code
loop at itab_A.
      read table itab_B with key
             employeenumber = itab_zmgr_training-empid binary search.
          if sy-subrc = 0.
Any thoughts?
Thanks,
Sk
Here I am getting the return value as '4'

I have tried all that, but why is it that while reading a record from itab_B I see no record in the header line,
Let me paste the entire code of what I am trying to achieve.
data: itab_A like A occurs 0 with header line.
data: itab_B like B occurs 0 with header line.
some validation.....
loop at itab_A.
read table itab_B with key employee number = empid binary search.
if sy-subrc =0.
per form validation.
else.
perform validation.
endif.
endloop.
My observation: while reading recrod from itab_B the header line is clear, no record is read here hence sy-subrc = 0.
How can I correct this? Since it is not reading any record from itab_B no matching record is found.
Any thoughts would be really helpful.
Thanks,
Santhosh.
