Insertion in Table having Column of object array type

Hi!
I want to make an object type and then the VARRAY of the that object type and then make table having column of VARRAY type.
How can i issue an Insert statement to insert values in columns of VARRAY type .
I will be thankful.

Hello
How to insert value in selected column of an array
In my program i am reading the CAN data from channels using
CAN read Channel API, the recent data read from the CAN channels
will be displayed in the indicator "Channel Data" 1D array, the
size of array depends on the number of channel selected for
monitor. i want to save all channel data.
i want to insert the first element of "Channel Data" array to
first column of "All Channel Data" 2D array, the second element
to the second column of 2D array...
i attached my VI

For 2D arrays, you must insert entire rows or columns at one time. You cannot insert just one element. Why? Lets say for example you have a 2 x 3 array (2 rows with 3 columns). If you insert an element in row 3 (a new row) column 1, what goes into columns 2 and 3? You just messed up the integrity of the array, and Labview doesn't allow that. What you need to do is gather data for all columns in the new row and insert the entire row. The Insert Into Array function is used with the row number wired to Row Index and nothing wired to column index. You can gather all your data, build a 1D array and insert that array into a new row in the 2D array.

How to insert data in a column with uniqueidefier data type

Guys,
I need insert data in a column with uniqueidefier data type, when i am trying to that getting error.
error message says: "Conversion failed when converting from a character string to uniqueidentifier."
I have data in table a col1,col2,col3,col4 - col3,col4 has datatype as varchar and i am updating table b columns col1,col2 with table a col3 and col4.
Please guide how to do it.

Hi,
Not any String can be convert to uniqueidentifier.
1. you have to make sure u use a value which is fir to be uniqueidentifier
2. Use convert or cast in the insert query in order to convert the string into uniqueidentifier
insert X ... convert(uniqueidentifier, 'string which fit to be convert to uniqueidentifier')
Please post DDL+DML for more specific help
DDL = Data Definition Language. In our case that is, CREATE TABLE statements for your tables and other definitions that are needed to understand your tables structure and there for let us to test and reproduce the problem in our server. Without DDL no one
can execute any query.
How to get DDL: Right click on the table in Object Explorer and select script table as CREATE. Post these create table scripts here.
DML = data manipulation language is a family of queries used for manipulating the data it self like: inserting, deleting and updating data. In our case we need some sample data in order to check the query and get result, so we need some indert query for
sample data.
If you post a "create query" for the tables and "insert query" with some sample, then we could help you without Assuming/Guessing. There is a reason that DDL is generally asked for and expected when discussing query problems - it helps
to identify issues, clarify terminology and prevent incorrect assumptions. Sample data also provides a common point of reference for the discussion. A script that can be used to illustrate or reproduce the issue you have, will encourage others to help.

Object array type casting?

Hi. I still can't get the hang of array type casting. Is it possible to type caste an array of objects? I tried the following
LabelledPanel[] comp = (LabelledPanel[])(content.getComponents());
in my program and I got the ClassCastException.
Exception occurred during event dispatching:
java.lang.ClassCastException: [Ljava.awt.Component;
LabelledPanel is a descendent of JPanel and getComponents() supposed to return Component[]

java does support casting with arrays. The following code will work:
String [] strings = new String[] { "1", "2" };
Comparable [] comps = (Comparable[])strings;
Object [] objects = (Object [])strings;That is, you can cast following the normal rules of assignment. You are having problems because your casting violates the normal rules of assignment- you're trying to cast a type into a differnt type that it does not extend or implement.
the toArray() in the Collections API really has nothing to do with casting. That method converts the current Collection into an array of the same type. Since all arrays extend java.lang.Object, it returns the new array as an Object, which you then cast into the specific type.
You may want to read the language guidlines on casting if you are having problems with it:
http://java.sun.com/docs/books/jls/second_edition/html/jIX.fm.html
you can also look at the documenation for Class.isAssignableFrom , which explains casting more briefly.

Insertion a record in a table having columns of different charsets using OLEDB

My development environment -
Database -> Microsoft SQL Server
2008 R2
OS -> Windows Server
2008 R2
Database Charset -> Chinese_PRC_CI_AS (Windows
936)
Operating System Charset -> Chinese
Below table is having varchar fields with different charsets.
create
table dbo.tcolcs1 (
    c1 int
not
null
primary
key,
    c2 varchar(30)
collate SQL_Latin1_General_Cp1_CI_AS ,
    c3 varchar(30)
collate Chinese_PRC_CI_AS
I want to insert below record using OLEDB APIs provided by Microsoft. Just for information, character '0x00C4' does not
belong to Windows 936 codepage.
insert
into dbo.tcolcs1
values (10,
NCHAR(0x00C4), NCHAR(0x4EBC))
Code snippet -
DBPARAMBINDINFO bind_info
memset(&bind_info,
0, sizeof(DBPARAMBINDINFO));
bind_info.pwszDataSourceType = L"DBTYPE_VARCHAR";
bind_info.wType = DBTYPE_STR;
I have bound the varchar field with DBTYPE_STR. I can see that my code is not inserting Latin1 character (0x00C4) correctly
into the table. The code always inserts a blank character into Latin1 column (c2) and 0x4EBC into Chinese column (c3).
Later, I changed the binding from DBTYPE_STR to DBTYPE_BYTES as below -
bind_info.pwszDataSourceType = L"DBTYPE_BINARY";
bind_info.ulParamSize =
0;
bind_info.wType = DBTYPE_BYTES;
With the above change, I observed that OLEDB is converting hex value to string. It is inserting 0x00C4 as 'C4' and 0x4EBC
as '4EBC'. I also tried with adding 'AutoTranslate=no' in driver connection string, but it did not help. How can I insert above record with OLEDB in the above table ?
Thanks in advance.

Issue in data Extraction , Source tables having columns wth lengthe 60

Hi BI Experts ,
Here I have a issue while extracting the data from Oracle tables. I encountered some columns for which the length of character stream is more than 60 , some where around 200 to 300 , for example : Reason for some action , Comments , discription .
I am not able to to treat them as master data text since these fileds are coming with the Transaction data . In SAP BI we can have the data type CHAR with length max to 60 . Now how can I deal this situation in a better way ??
Could you please come up with your ideas .

How to know a table's column name and its types

if there has one table called "myEmp" stored in my database, it uses to hold employees' information. when a newcomer is hired, the HR will use a register page to register his/her information. for the flexible purpose, i couldn't know how many columns in this table, since it may be added two columns or deleted one column in one day, all i should do is show all fields in the register page and get all data to insert into this table.
so, how can i know one table's structure in java? i know there has a method in DatabaseMetadata class: getTables(catalog, schema, tablename, tabletype), it's return is resultset . i wrote a code below:
DatabaseMetaData md = conn.getMetaData();
ResultSet md.getTables(null, null, tablename, types);
i set catalog and schema both are null since i don't know what else can i set?
the ResultSet doesn't contain the information i want.
is there anyone can tell me where i am wrong and the right method? thanx a lot!
sincerely
Jasmine

use ResultSetMetaData to get Column names

How to get the rows from a table having some column has any letter

Hi All,
suppose i have a table having columns id(number), code(varchar).
code has alphanumeric characters (ex. ABC123, 67B56 etc).
some codes are only numbers (2344, 7898 etc).
how can i get the rows which have alphabets in the code.
ex:
id code
1 AB45
2 456
3 890
4 67B7
how can i write a query such that it should give me the ids 1 and 4 (as they have alphabets in code)
thanks in advance to all

Thanks to one and all.
i am gettig my required output.
But i have a doubt in the operator.
If i add or remove '[]' in the operator, i am getting different ouputs.
There is a count difference in the result of the operators used.
REGEXP_LIKE(<column>,'[[:lower:]]')
REGEXP_LIKE(<column>,'[[[:lower:]]]')
REGEXP_LIKE(<column>,'[:lower:]')
Can anybody please explain what is the difference in using '[]', in the operator?
What is the correct syntax, whether i have to use two '[]'s or one '[]'.
Also, can i use REGEXP_LIKE() in oracle 8i version.( I am unable to use the operator in 8i)?
Any query to get the required output in 8i version?
Thanks in advance to all.

Problem in truncate/drop partitions in a table having nested table columns.

Hi,
I have a table that has 2 columns of type nested table. Now in the purge process, when I try to truncate or drop a partition from this table, I get error that I can't do this (because table has nested tables). Can anybody help me telling how I will be able to truncate/drop partition from this table? IF I change column types from nested table to varray type, will it help?
Also, is there any short method of moving existing data from a nested table column to a varray column (having same fields as nested table)?
Thanks in advance.

Unfortunately you can't do those operations when a table has a nested table column. No truncate, no drop, no exchange partition at the partition level.
A nested table column is stored as a separate table and acts like a 'child' table with foreign keys to the 'parent' table. It is these 'foreign keys' that prevent the truncation (just like normal foreign keys prevent truncating partions and must be disabled first) but there is no mechanism to 'disable' them.
Just one excellent example (there are many others) of why you should NOT use object columns at all.
>
IF I change column types from nested table to varray type, will it help?
>
Yes but I STRONGLY suggest you take this opportunity to change your data model to a standard relational one and put the 'child' (nested table) data into its own table with a foreign key to the parent. You can create a view on the two tables that can make data appear as if you have a nested table type if you want.
Assuming that you are going to ignore the above advice just create a new VARRAY type and a table with that type as a column. Remember VARRAYs are defined with a maximum size. So the number of nested table records needs to be within the capacity of the VARRAY type for the data to fit.
>

Sure - just CAST the nested table to the VARRAY type. Here is code for a VARRAY type and a new table that shows how to do it.
-- new array type
CREATE OR REPLACE TYPE ARRAY_T AS VARRAY(10) OF VARCHAR2(64)
-- new table using new array type - NOTE there is no nested table storage clause - arrays stored inline
CREATE TABLE partitioned_table_array
     ( ID_ INT,
      arra_col ARRAY_T )
     PARTITION BY RANGE (ID_)
     ( PARTITION p1 VALUES LESS THAN (40)
     , PARTITION p2 VALUES LESS THAN(80)
     , PARTITION p3 VALUES LESS THAN(100)
-- insert the data from the original table converting the nested table data to the varray type
INSERT INTO PARTITIONED_TABLE_ARRAY
SELECT ID_, CAST(NESTED_COL AS ARRAY_T) FROM PARTITIONED_TABLENaturally since there is no more nested table storage you can truncate or drop partitions in the above table
alter table partitioned_table_array truncate partition p1
alter table partitioned_table_array drop partition p1

Excel & ActiveX: Insert arbitrary columns from 2D array and create graph problems

Hi there,
I want to insert data from either a 1D or 2D array from LabView into Excel and create graphs.
I used the information from the following example:
http://www.ni.com/example/28934/en/
and was able to create a new Excel file (I'm using Excel 2010), writing data from an 1D array to a column in excel by creating a while loop and using the first element of the array to write it to a specific cell. I use the counter of the loop to write to the next cell when the loop starts over and always delete the first value, which I write to the cell, from the array until it is empty.
Now I also would like to write a 2D array - so the first column in Excel should be the first column from the array and so. Here I cannot use the loop counter directly as Excel only counts 1,2,... for the rows, but uses A,B,... to count columns. Also I do not know in advance how many columns my 2D array will contain, so creating a lookup table like (A means 1, B means 2,...) is not really an option (except there really is no other way). Is there a possibilty to convert numbers into letters or some way to 'explain' to the program that column 2 in the array means column B in Excel for example, or is there a way to insert new columns?
I figured out how to add new Worksheets and as I also need to create a certain number of Worksheets and I know that on standard 3 sheets are present when creating the file, I use the 'add' methode to create every new worksheets before worksheet 3 - I could use the same methode to create new columns in Excel, but so far I didn't find a methode to do so. Or is there a way to enter the whole 2D array at once?
Then I'd like to create a graph (in case of the 1D arrays a bar plot, when using 2D arrays a 3D plot) to view the data. I found this example:
http://www.ni.com/newsletter/51339/en/
-> as I do not have the toolkit I'd like to do it using ActiveX directly, so I tried to do things like shown under the headline 'DIY ActiveX/.NET'
I tried to load the snippet to a new Excel file but got the error message 'microsoft.office.interop.excel.dll not found' and hence the code is not working. That confuses me a little as I would guess when this dll is not present I cannot access Excel from LabView at all, though my understanding of what I'm really doing so far is quiet limited. ;-)
Also - as far as I understand from the snippet - when creating a new chart object I should be able the create methodes for it, however when I do a right click on the chart object of an ActiveX Worksheet symbol there are none listed.
To explain my problems better I added a snippet showing my two problems: The inner of the two while loops shows how I import a 1D array. In the outer loop I seperate the columns. I know that currently this is not working as all data end up in column A of the Excel sheet - so I would need to convert the number of the outer counter to A, B,... or find a different solution.
Moreover on the snippet I placed an ActiveX Worksheet Property with the Chart Object - as I can see the difference to the Chart Object in the example code from the last link above is the color. However I'm not sure what that means and how to change/ solve this.
And just to make sure - I know this way the VI does not run as the Chart Object is placed completely wrong - I just did it, so it is included in the snippet.
I'd be thankful for any suggestions,
Thanks!
Solved!

Hello everyone and thanks for the answers.
I only have the LabView Student Edition available here - is the toolkit included in it too. How can I check if it is installed/ available and in case it is installed - where can I find it?
Today I had time to take a look at the example
Create via ActiveX Labview a XY Scatter plot graph on an excel sheet
It almost does what I want in terms of creating a graph. The only problem I could not fix, is that in this example a sheet is created where only the graph is present. i'd like to add the graph to a previously created worksheet. Today I tried get this working but it seems I stilll don't really understand what I'm doing, I'll post a snippet of my code as soon as I can access the PC with LabView on it again.
I also took a look at the other example for inserting 2D attays - it seems to be what I need, I just had no time so far to test it, I'll post an update when I could test it.
Thanks for the help so far!

end associative_array;
this procedure is called from .net. from .net sending blob is posiible or not.if yes how

Ok, that won't work...you need to generate an image tag and provide the contents of the blob column as the src for the image tag.
If you look at my blog entry -
http://jes.blogs.shellprompt.net/2007/05/18/apex-delivering-pages-in-3-seconds-or-less/
and download that Whitepaper that I talk about you will find an example of how to do what you want to do. Note the majority of that whitepaper is discussing other (quite advanced) topics, but there is a small part of it that shows how to display an image stored as a blob in a table.

Combine Columns From Separate Arrays Into One Formatted Table

What I'm trying to do is make two WMI queries with 2 different classes for a list of machines and then patch the columns together into one single array that is formatted as a table with columns and rows. I seem to keep banging my head against the wall and
I can't help but feel that the answer is simple. I can certainly create an array that contains all 3 columns (such as in the commented out part) but no matter which angle I go at it, it always seems to end up as all the data in one single row in each column
rather than a nicely formatted table. I've even tried constructing separate custom objects and adding the different objects to the array but that's obviously not working. Below is the code of the last thing I tried. I need someone to bash it to death and tell
me the (most likely obvious) thing that I'm doing wrong. Thanks!
