To load that file with BULK INSERT, use this format file:
9.0
4
1 SQLCHAR 0 0 "\"" 0 "" ""
2 SQLCHAR 0 0 "\",\"" 1 col1 Latin1_General_CI_AS
3 SQLCHAR 0 0 "\",\"" 2 col2 Latin1_General_CI_AS
4 SQLCHAR 0 0 "\"\r\n" 3 col3 Latin1_General_CI_AS
Note that the format file defines four fields while the fileonly seems to have three. The format file defines an empty field before the first quote.
Or, since you already have a .NET program, use a stored procedure with table-valued parameter instead. I have an example of how to do this here:

You can search this forum to see how to PIVOT your data. There are lot of example. You can also try dynamic pivot. Its all in here, just search.

Query for comparing two columns in two tables

Hai, all,
I have following two tables and columns, I need to get the rows (all columns) from scott.cp_ip which are not ( the same value present in t1 and also in t2).
Table scott.cp_ip column cp_ip.vrno = Table scott.cb1 column cb1.cb_vnno
I used the following query and did not get the correct result:
select * from scott.cp_ip where cp_ip.vrno in (select cb1.cb_vnno from scott.cb1);
Can you please tell how it can be solved?
Thanks in advance.

Instead of SELECT * write only the column that you want to compare. I guess that would be cb1.cb_vnno and cp_ip.vrno.

Query Designer - Rows between Columns

Dear all,
I've got the following requirement and I really cannot figure out if it is doable.
I would appreciate your help.
I shall create a query using Sap Query Designer regarding the actual and budet data of the assets (it's a financial report).
I'll have 2 columns for the actual data and 2 columns for the budget data.
Is there any way:
a) to have the assets (the rows) in the middle of the report layout, and
b) the actual data on the left side of the assets, and
c) the budget data on the right side of the assets
The goal is when drilling down the assets, both pairs of columns to be expanded as well.
Is it doable? Is there any trick?
Thanks in advance.

Dear Riyez
I do thank you for your response.
I am wondering if there is something someone could possibly do on the Query Designer side in order to fool the system.
For instance, to design a virtual structure (I do not know how - I am thinking loudly) which would be identical to the structure that holds the assets?
In other words, is it designeable to have a row structure, then the column key figures and, finally, another row structure identical to the first one? And when the user expands the first structure, the second structure will follow accordingly?
Or such a solution is out of question?

Query for row by rows-before using seq number

Hi,
I have a table of CatalogAuthor records
long : id
varchar : author
long : seqnum
I have made the table so that initially, if there are 10000 unique authors, then the rows will have sequence numbers from 1 to 10000. As authors are dynamically added, they are given the sequence number of an existing row in the table, i.e. the nearest row whose author comes before the new author. As time goes there are more and more duplicates, and at a certain point, the table has all its sequence numbers reassigned to be monotonic increasing by author name order.
We want to use this table to build a tree of about 10 nodes per parent, culminating in author names. So to expand the tree at the first level, we could divide 10000 by a suitable power of 10 to get the groups of sequence numbers. However, with duplicate seqnum, there may be 14365 rows so ideally, to overcome the problem of clumping, I would do some kind of query to identify the 1436 record in sorted order by sequence number, the 2872 record by seq number and so on.
What query would that be? With appropriate indices, would it still be slow? Would I have to do 10 of these queries to expand one node with 10 children? Is there a better design to accomplish the same goal of exploding a balanced tree by author name sort order, culminating in a leaf of one particular author?

What will this tree structure do for you that an index on author won't do?
I don't know of any way to automatically keep a tree balanced every time DML is done.
You could periodically re-balance the tree; that shouldn't be too hard. Let's say you want each parent to have up to r children. Use the analytic ROW_NUMBER function to assign unique numbers 0, 1, 2, 3, ... to each row, in order by author.
The row numbered 0 will have no parent
For all all rows numbered n (n > 0), the parent will be the row numbered FLOOR (n/r).
Whenever you re-configure the tree, use a MERGE statatment. An index on author will probably make generating the ROW_NUMBERs faster.
If you need help, post CREATE TABLE and INSERT statements to show the table as it exists with the tree out of balance, and also show how you want it to look after balancing. Use a small value of r (maybe 2 or 3) to keep the sample set small.

Select query for rows where condition 1

Say I have a table, tb1, that has the following entries:
FName LName
Code
John Doe
xxx
Jane Doe
xxx
Steve Harper
x
Barrak Obama
x
George Bush
xxxx
Bill Clinton
xx
I'd like to write a select query that only lists the rows where the count for Code is > 1, i.e not display the last two rows from the above entry. How would I go about writing that select query.
Thanks.

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
>> Say I have a table, tb1, that has the following entries: <<
Are you this rude or really ignorant and too lazy to read the Netiquette at the start to this forum? Why do you think you do not need a key? No DDL? No constraints? And , why, why do you think that “tb1” is a precise, ISO-11179 conforming table name?
Let's make this a table of rude posters rated on a 4-star scale.
CREATE TABLE Rude_Posters
(first_name VARCHAR(15) NOT NULL,
last_name VARCHAR(15) NOT NULL,
PRIMARY KEY (first_name, last_name),
rudeness_code VARCHAR (4) NOT NULL
CHECK (rudeness_code IN ('x', 'xx', 'xxx', 'xxxx'));
INSERT INTO Rude_Posters
VALUES
('John', 'Doe', 'xxx'),
('Jane', 'Doe', 'xxx'),
('Steve', 'Harper', 'x'),
('Barrack', 'Obama', 'x'),
('George', 'Bush', 'xxxx'),
('Bill', 'Clinton', 'xx');
>> I'd like to write a SELECT query that only lists the rows where the count for rudeness_code is > 1, i.e not display the last two rows from the above entry. <<
The rudeness scale is based on stars, so to ask for an integer value is like saying “on a scale from 1 to 10, what is the color of your favorite letter of the alphabet?”
Next, the number of stars and your narrative do not match. Did you want to say WHERE rudeness_code IN ('xx' 'xxx', 'xxxx')?
Please stop programming SQL until you have gotten more education. At this point, you do not know enough to ask a question.

Hi All,
I think you misunderstood my question, so may be I didnt ask it properly, so here it is I am explaining in detail with an example.
Suppose I have 10 users with 10 different user name's in a database and I am the 11th user as DBA, every 10 of these users have created some tables lets say 20 tables each by every user making a count of the total tables as 200, now lets say 10 of 200 tables has a column ie fname with value as 'rahul', I want to search the string 'rahul' from all the 200 tables that which of the tables contains this string along with the column name.
I hope this time my question is clear, the point is I just know of a value and I dont know the table name and column name where it may actually residing, futher I want to search tables of other users as well.

Creating a header for rows/columns in cross-tab with syntax

Hi,
The issue is creating strings for rows or columns' headers. How can I create a formula field which contains more than one seperate string. Such as "aaa", "bbb" and "ccc" are headers and they should be in seperate columns. In short, they will behave like characteristics of one of my query's field but they are just headers of the columns.
..............aaa...bbb...ccc....
row1.......x.......x........x.....
row2.......y.......y........y.....
Also there is another issue about the formulation again. Is there any operator that does the same job as " \n" which is used in C languages to break the line?
before:
aaabbb
after:
aaa
bbb

Hi Carl;
Firstly, thanks for answering my question. To explain my problem there are two options ahead(for my first question); first one is writing down the actions step by step, the second one is posting an image file(jpeg etc) to visualize it. I think the first one will be enough. If not tell me
Step 1- Create a cross-tab and right click and select cross-tab expert.
Step 2- Click the button "New Formula" and write down any word(such as "Sales") between two -"- sign to make it string.Then save and close.
Step 3- Drag and drop the created formula to "columns" section and fill the other necessary sections with your database's(such as xtreme.mdb which is famous for crystal users) fields.Don't forget to add another column value to "columns" section, since our formula has no link to database.
Step 4- Then click OK to save the changes and lets preview the cross-tab.The result will have one top column and his child or children(that depends on your data). And this top column is behaving like a header not a field.
Now turn the second step but write down a formula for 2 columns or more.For exmple "Sales" and "Profit".So the result will have 2 top columns and their child/children.
My question is "what is the formula for 2 or more columns?"
Also I couldn't get the answer for my second question. What is the meaning of expressions "\c" and ChrW(13)?

How to color Rows and Columns of BI Query

Hi to all,
I have created BI query in query designer, with 2 structures for rows and Columns.
Now I need that certain rows can be colored orange and certain columns as green color.
I knew that it can be done in Query designer, but slice and dice reporting can not be done, which I required in my report.
Is there any way I can do in WAD.
or any other way to do that.
i shall be thankfull to you for this.

Hi Rana,
You can do the coloring of KF values using the report designer tool.

Display of Row and Column Headers in NW2004s Bex Analyzer

Hi all,
when I open a query with the NW2004s Bex Analyzer (Excel)Frontend Row and Column Headers are not visible. I need to go to "Tools-Options" and check the box for "Row and Column Headers" which seems to be unchecked by default.
Is there a possibility to make the Row and Column Headers visible by default when I open a query so that I don't have to use Tools-Options every time.
Thanks
Alex

This is fixed with SP8. The default template doesn't have this specified in SP7. It's a very easy fix. Just specify that the column headers are specified by default. Then save this new workbook as the global workbook template such that all queries use this new template. You can customize this standard template however you like!

Help! Inserting a 1-D comment array into a 2-D string array at specified row AND column

Hello everyone,
I am writing a 2-D string array to excel and i need a way to add comments to my file like this:
SLAM NAME G Level Comments
1 RALF 26
1 RALF 26
1 RALF 26
1 RALF 26
For some reason, i cannot specify a row AND column to write because:
When i use replace array subset it only replaces 1 element at my index.
When i use replace array subset with a loop, it creates empty spaces until it reaches the end of the array it is replacing.
When i use Insert into array: i cannot wire 2 inputs for row and column.
In my complete VI i will need to write from row 1-1001, a different comment from 2-2002, a different comment from 3-3003, etc until a stop condition is met so i need to figure out how to do this programatically and not have it replace any elements outside of the range or it will override previous commetns.
I am at a loss of what to do. Any and all suggestions are greatly appreciated.
Thanks!

Hi proph,
I made a small subtile change to yur VI and now it replaces all values of the 4th column…
THINK DATAFLOW!
Use shift registers when you need to propagate values from one loop iteration to the next!

There are tools like probes and highlight to understand your VI execution and to find problems…
