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?
thanks
I use Visual studio 2012 Ultimate and SQL server 2008 developer edition!
Why not below? May be you will not be able to change your design now, but just want to share.

How to update multiple columns from different tables using cursor.
Hi,
i have two tables test1 and test2. i want to udpate the column(DEPT_DSCR) of both the tables TEST1 and TEST2 using select for update and current of...using cursor.
I have a code written as follows :
DECLARE
v_mydept1 TEST1.DEPT_CD%TYPE;
v_mydept2 TEST2.DEPT_CD%TYPE;
CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR;
BEGIN
OPEN C1;
LOOP
FETCH C1 INTO v_mydept1,v_mydept2;
EXIT WHEN C1%NOTFOUND;
UPDATE TEST2 SET DEPT_DSCR = 'PLSQL1' WHERE CURRENT OF C1;
UPDATE TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1;
END LOOP;
COMMIT;
END;
The above code when run says that it runs successfully. But it does not updates the desired columns[DEPT_DSCR].
It only works when we want to update single or multiple columns of same table...i.e. by providing these columns after "FOR UPDATE OF"
I am not sure what is the exact problem when we want to update multiple columns of different tables.
Can anyone help me on this ?oops my mistake.....typo mistake...it should have been as follows --
UPDATE TEST1 SET DEPT_DSCR = 'PLSQL1' WHERE CURRENT OF C1;
UPDATE TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1;
Now here is the upated PL/SQL code where we are trying to update columns of different tables --
DECLARE
v_mydept1 TEST1.DEPT_CD%TYPE;
v_mydept2 TEST2.DEPT_CD%TYPE;
CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR;
BEGIN
OPEN C1;
LOOP
FETCH C1 INTO v_mydept1,v_mydept2;
EXIT WHEN C1%NOTFOUND;
UPDATE TEST1 SET DEPT_DSCR = 'PLSQL1' WHERE CURRENT OF C1;
UPDATE TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1;
END LOOP;
COMMIT;
END;
Please let us know why it is not updating by using using CURRENT OF -
Need to compare values in two columns of one table against values in two columns in another table
Hi, as the title reads, I'm looking for an approach that will allow me to compare values in two columns of one table against values in two columns in another table.
Say, for instance, here are my tables:
Table1:
Server,Login
ABCDEF,JOHN
ABCDEF,JANE
FEDCBA,SEAN
FEDCBA,SHAWN
Table2:
Server,Login
ABCDEF,JOHN
ABCDEF,JANE
FEDCBA,SHAWN
In comparing the two tables, I'd like my query to report the rows in table1 NOT found in table2. In this case, it'll be the 3rd row of table one:
Server,Login
FEDCBA,SEAN
Thanks.create table Table1([Server] varchar(50), Login varchar(50))
Insert into Table1 values ('ABCDEF','JOHN'),('ABCDEF','JANE'),('FEDCBA','SEAN'),('FEDCBA','SHAWN')
create table Table2([Server] varchar(50), Login varchar(50))
Insert into Table2 values ('ABCDEF','JOHN'),('ABCDEF','JANE'), ('FEDCBA','SHAWN')
select [Server] ,Login from Table1
Except
select [Server] ,Login from Table2
select [Server] ,Login from Table1 t1
where not exists(Select 1 from Table2 where t1.[Server] = t1.[Server] AND Login=t1.Login)
drop table Table1,Table2 -

Varsha.Hi,
Hi ,
You will need to group that radiobuttons so that SAP knows they are linked together. To do this using the grahical layout editor simply select all the radiobuttons and then right click on them, Now choose define group. Once you have done this you should not need any of the "clear" or "='X'" statements SAP should control it all for you.
hope this helps

How do I count the unique value pairs in two columns of a table?
I have a table (Table 2) that is populated with data from an imported .csv file. On table 1 I need to count the unique value pairs in two columns of Table 2.
Here's what I have:
Date Person
7/10/2011 A
7/12/2011 W
7/12/2011 X
7/12/2011 X
7/12/2011 X
7/12/2011 Z
7/14/2011 Z
7/15/2011 X
7/16/2011 Z
I'm focusing on person "X" and can easily count how many days that person shows up but what I want is to see on how many unique days that person shows up.
Here's the result I'm looking for (Person "X" shows up on 2 different days - 3 times on 7/12/2011 and once on 7/15/2011):
X 2
I can't seem to find a function that allows me to do that. I also am not allowed to modify Table 2 so that leaves me to come up with a solution on Table 1.
Any ideas would be greatly appreciated.Hi John,
Not being allowed to modify Table 2 is a minor inconvenience. Just copy (using a formula) the necessary two columns onto Table 1.
Yellow columns may be hidden. The procedure progresses from left to right. All formulas are entered into row 2 then filled down that column to the end of the table. The table must be as long as the list in column A of Table 2.
A2: =Table 2::A
Fill right to column B.
Fill both columns down as far as needed.
I've used actual Date and Time values in column A, formatted to show only the Date part, but the technique will work with text in these cells, provided all cells representing the same 'date' have exactly the same content.
C2: =A&B
This concatenates the contents of each row of columns A and B into a single text string.
D2: =COUNTIF($C$2:C2,C)
This counts the number of occurrences of the Date&Name string on the current row from the first regular cell in column C (C2) to the current cell.
E2: =IF(COUNTIF($B$2:B2,B)=1,MAX($E$1:E1)+1,"")
This constructs the index of first occurrences of each name, in the order they first occur. The index is used by LOOKUP in column F.
F2: =IF(ROW()-1>MAX(E),"",LOOKUP(ROW()-1,$E,$B))
This uses the index value created in E as a search-for value to extract a single copy of the names in column B. The result is a list of all distinct names in the list. Note that spelling differences will be counted as distinct names.The IF statement stops the listing when the last distinct name is extracted.
G2: =IF(LEN(F)>0,COUNTIFS($B,"="&F,$D,"=1"),"")
This counts the number of 'first occurrences of distinct Date & Name strings for each name on the list (ie. the number of distinct dates on which each name appears in the original list).
All of the functions used are described, with at least one example for each, in the iWork formulas and Functions User Guide. You can download the guide, and the Numbers '09 User Guide, via the Help menu in numbers.

Hi All,
Am using OPENROWSET to load the file data into table, here the problem is i need to map same input value to two different columns of table, As format file doesn't allow the duplicate numbers am unable to insert same value to two columns, please help me to
find a solution for this.
i can use only OPENROWSET because i need to insert some default values also which come based on file. only the problem is how to map same input value to two different columns of table. please give me the suggestions.
Thanks,
SudhakarFrom what you say:
INSERT tbl(col1, col2)
SELECT col1, col1
FROM OPENROWSET(....)
But I guess it is more difficult. You need to give more details. What sort of data source do you have? What does your query look like? The target table?
Erland Sommarskog, SQL Server MVP, [email protected]
Hi Erland,
Thanks for your response
my source file is text file with | symbol separate for ex:
1002|eTab |V101|eTablet|V100|Logic|LT-7|Laptops|SCM
Database table have columns like
column1,column2,column3...etc, now i need to insert same value from input file into two columns for ex:
the eTab value from text file has to be insert into column2 and column3 of
table
we cannot change format file like below one
for the above situation how can we insert eTab into column2 and column3
Thanks,
Sudhakar.
