Compare two columns between two tables
Hi all,
I have two separate datasets in Table 1 and Table 2.
Both datasets have Column A First name and Column B Last name in common.
The data in the subsequent columns is different.
Some of the people listed in each table are the same.
I want to delete the people from Table 1 who are in table 2.
If I run a formula like this =COUNTIF(Table 1 :: A2:A200, A2) I can return a 1 or 0, use conditional formatting to colour that cell, sort the table and delete all the rows containing 1.
However that only checks for First Name.
What I need to do is check if First name AND Last name in Table 1 are the same as First Name AND Last Name in Table 2 - and then return a True of False (1 or 0 or anything) in a separate column.
Please help.
Thanks in advance.

Presumably this lets me compare multiple values across multiple tables also?
Moich,
As you will see as you become familiar with this function, it can only count rows in one table. The comparison (criteria) values can come from anywhere, but what you are counting are "records" that meet the multiple criteria. A record is one row. I think that was your question, but I'm not positive.
I can't seem to find how to insert formulas into the conditional rules.
You'll have to put the formulas elsewhere and refer to them with simple comparisons.

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
ManuHi,
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.. -

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 -

Create ViewCriteria comparing two columns from same table
Does anyone know how I can create a ViewCriteria where clause that compares two columns from the same table?
For example if I had two integer columns (MINSAL and MAXSAL) and wanted to see if they are equal. I would normally do the following SQL below.
SELECT * FROM EMPL
WHERE MINSAL = MAXSALIt works, but it is not ideal.
Setup a Transient column that performs a groovy evaluation of MINSAL=MAXSAL and then my ViewCriteria evaluates the column to true and I set Query Execution Mode to Both. -

result=instead of 1408 rows, 1481 rows (excess 73 rows) getting!
----------Instead of SELECT * write only the column that you want to compare. I guess that would be cb1.cb_vnno and cp_ip.vrno.

Division between two columns in pivot table in Answers
Hi all
In answers
if I have two columns in my pivot table say column A and Column B, how can I use a division of Column B by Column A to derive Column C. I am unable to do that using the "New Calculated column feature" or in the criteria section. I keep getting either 0 or 1. I even tried changing the format to show two decimal places and am still unable to get the result.
Thanks
BThanks,
our issue is that we want to do our calculations at the summary level (region level of the company) and not at the detail level. However we cannot do this at the aggregate level because this is a moving total for the last 7 days worth of data.
Also, Answers (even in Criteria) does not seem to be doing division properly. We are just not getting the results when we do col A/ Col C. We are in 10.1.3.4 on windows xp against SQL Server
Any ideas?

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?

How to insert a local member in a column between two different nested row dimensions
Hi Experts,
We have a report which has two dimensions in rows with nesting. The dimensions are PROGRAMS and ACCOUNT.
I have attached the layout of the report.
We need to have a column for local member in between Col A and Col B, wherein we have to pull the long description of the program.
We have long description of programs maintained in a property of PROGRAM dimension
So if we can insert a column between Col A and Col B, we can have a local member in it with formula "EPMMemberProperty" refering to Col A
Currently we are are not able to insert a local member in between Col A and Col B in EPM 10 SP 14 version because its not a data range
I remember we used to do it in BPC 7.5 using expansion ranges to insert a blank column. So I believe similiar thing can be done in EPM 10
I have tried the option of VBA macro to insert a column before Col A and populate the long description and then hide Col A. It works. But I dont want to complicate it with Macro, and want to use EPM functionality to achieve the same.
Please advise if this is possible with BPC 10 to have a column for local member in between Col A and Col B.
Thanks a lot in advance.
Regards,
ShivaHi Sathish,
Thanks a lot for replying. Since I had to insert the local member in between two dimensions, I couldnt use the position option in the local members. Because positions were staring from the data range.
How ever I have tried the suggestion given by Varaprasad and Bishwajith above and it worked.
Thanks,

Spry validation text field across two columns in a table?
I have a table with two columns. I can easily insert a spry validated text field into the left cell but when I drag the box over so that box is in the right column and the label is still in the left column then that breaks the widget.
Is this even possible for me to do or do I have to put the widget in just one column?Think I figured it out.

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.

Calculation on two columns in pivot table
Hello all,
I have a view:
Dept Year Amount
Accounting $500 2010
Accounting $700 2011
Engineering $100 2010
Engineering $600 2011
and etc
pivot table:(data displayed side by side)
Dept: 2010 2011
Accounting $500 $700
Engineering $100 $600
Is there a way in pivot table to create additional column and do a calculation on that column? New column called 'Change' (actual calculation amount of 2010 minus amount of 2011 per each department). I see the feature which allows to duplicate the columns in pivot table. But this is it... no additional calculations.
Thank you in advance,
SonyaDeepak,
My "YEAR_NO' is already in the column area. Once I created 'calculated column' and entered formula '2011'-'2010' I got what I needed.
Thank you very much for the solution.
Sonya
In my view I also have column called EXPENSE. When, I added the 'calculated column' to 'YEAR_NO' with formula '2011'-'2010'. It created two calculated columns 1) after the EXPENSES and the other one after YEAR_NO. Is there a way to be specify to display the DIFFERENCE only once after the YEAR_NO??

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,

Universe Design - Linking two columns in a table to a subordinate table
Post Author: bradwist
CA Forum: Semantic Layer and Data Connectivity
I hope this is the right forum to ask a question about Universe Design. If not, please redirect me. Thanks.
I have a question on a universe design that I am trying to implement. I'll try to simplify to what I really am focusing on here. I've got a table, PersonRelationship, that defines a relationship between two people (Person1, Person2). Both Person entities have a set of data that are contained in the PersonTable. I'm trying to set up a universe design that allows the PersonRelationship table to join to the Person table twice, for Person1 and Person2 (fields are Person1Id and Person2Id respectively).
(below is a poor attempt to draw the table relationships)
Person (table) PersonRelationship (Table) OtherData (table)
PersonId (PK) RelationshipId (PK) OtherDataId (PK)
^----
Person1Id (FK)
^----
Person2Id (FK)
OtherDataId (FK) -
^
I then would like to build a query in Web-I that allows me to query against certain parameters for both Person1 and Person2. For instance, I may want information that reflects when Person1 is male and Person2 is female.
Is there a way to establish this relationship within the universe without having to create two physical tables?
Thanks.Post Author: bradwist
CA Forum: Semantic Layer and Data Connectivity
With further information, I believe the answer to this is Aliasing the table. But when I create and Alias of the person table, it doesn't show up in WebI. I only see the original. Not sure what the problem is.
