[sqlldr] upload number datatype from varchar2 datatype in ctl file

dear friends.
this is two files from my DAT file.
In the last field the data is: |3180.8| or |605.|

in the table destination the field have NUMBER(12,2) and i want to upload in this datatype in my control file.
I had read about portable and non-portable datatypes but i dont understand. This topic is refer about my problem?
In other ways, what will be the instruction in order to upload this datatype ???
Thanks a lot.

Converting datatype from Varchar2 to BLOB ...how..???

Hi i have to convert the datatype of a varchar2 column in one of my tables to BLOB...and i also have to preserve the data existing in the column in the process.
Please guide .
Thanks.

first of all, I don't think that BLOB and VARCHAR2 are compatible, logically that is. BLOB is binary and VARCHAR2 is mere text.
The way I'd do it is to have all the VARCHAR2 saved into text files and then stored in BLOB. Here is a hint:
let's call your VARCHAR2 column 'X'
1- create a new column in the table of type BLOB and call it 'Y'.
2- using pl/sql text I/O, save each VARCHAR2 in a text file using the primary key of the table as file name.
3- upload each file back to the table in it's corresponding record in column 'Y'.
4- update the table setting 'X' in each table to NULL.
5- alter table to delete column 'X'.
6- alter table to rename 'Y' ---> 'X'
finally, before doing any of these steps make sure you have enough disk space and that you really know how to deal with BLOB's as they need special insert and update commands.
hope that helped

Change column datatype from varchar2 to number(10) and keep existing data

Hi,
I need to change the datatype on a column that already has data in it from a varchar2 to number(10). The data that is already there is not necessarily number data, however I must be able to keep the old data to. We are running 10g. Does anyone have any ideas? Thanks. Here's the current data.

SQL> drop table t purge;
Table dropped.
SQL> create table t(i int, x varchar2(10));
Table created.
SQL> insert into t values(1, 'T1');
1 row created.
SQL> insert into t values(2, 2);
1 row created.
SQL> --
SQL> alter table t add (xn number);
Table altered.
SQL> --
SQL> begin

Run time error INVALID DATATYPE from package

Hi,
I compiled the package spec. and body. But, when I issue select mytest_pack.get_res_set from dual, oracle return invalid data type error.
My requirement to develop packaged function need to return multiple rows by using record type. This can be achieved by using pipe lined function or
sys refcursor. But, I would like the packaged function return must return record type.
Can you pl. correct this package code.
Thanks,

insert into mytable values (2, '[email protected]', 'YOPT 1', 'OPT 2', 'OPT 3', sysdate);

I dont see any problem with your code.
The problem is with "select mytest_pack.get_res_set from dual"
You cannot select complex datatypes from dual.
Why dont you try an anonymous pl/sql block and try assigning the record values into another record or table.
select xxx into xxx ...

How to convert number datatype to raw datatype for use in data warehouse?

I am picking up the work of another grad student who assembled the initial data for a data warehouse, mapped out a dimensional dw and then created then initial fact and dimension tables. I am using oracle enterprise 11gR2. The student was new to oracle and used datatypes of NUMBER (without a length - defaulting to number(38) for dimension keys. The dw has 1 fact table and about 20 dimension tables at this point.
Before refining the dw further, I have to translate all these dimension tables and convert all columns of Number and Number(n) (where n=1-38) to raw datatype with a length. The goal is to compact the size of the dw database significantly. With only a few exceptions every number column is a dimension key or attribute.
The entire dw db is now sitting in a datapump dmp file. this has to be imported to the db instance and then somehow converted so all occurrences of a number datatype into raw datatypes. BTW, there are other datatypes present such as varchar2 and date.
I discovered that datapump cannot convert number to raw in an import or export, so the instance tables once loaded using impdp will be the starting point.
I found there is a utl_raw package delivered with oracle to facilitate using the raw datatype. This has a numbertoraw function. Never used it and am unsure how to incorporate this in the table conversions. I also hope to use OWB capabilities at some point but I have never used it and only know that it has a lot of analytical capabilities. As a preliminary step I have done partial imports and determined the max length of every number column so I can alter the present schema number columns tp be an apporpriate max length for each column in each table.
Right now I am not sure what the next step is. Any suggestions for the data conversion steps would be appreciated.

Hi there,
The post about "Convert Numbers" might help in your case. You might also interested in "Anydata cast" or transformations.

How to get a time part from Date datatype

Hi,
I would like to know how to extract the timestamp alone from DATE datatype? If my input is '27-SEP-2011 23:59:00' I need the output as 23:59:00. I am surprised to see that there are no in-built functions for this or may be I am wrong. Basically I need to remove the date part from DATE data type and get the time.Please assist.

Hi,

There is a built-in function, TO_CHAR:
TO_CHAR (dt_col, 'HH24:MI:SS')Depending on how you plan to use the time, TRUNC is another handy built-in function:
dt_col - TRUNC (dt_col)is a NUMBER (not less than 0, but less than 1) which is suitable for many tasks, such as finding the average time.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using.

Difference between CHAR and VARCHAR2 datatype

Difference between CHAR and VARCHAR2 datatype
CHAR datatype
If you have an employee name column with size 10; ename CHAR(10) and If a column value 'JOHN' is inserted, 6 empty spaces will be inserted to the right of the value. If this was a VARCHAR column; ename VARCHAR2(10). How would it handle the column value 'JOHN' ?

The CHAR datatype stores fixed-length character strings, and Oracle compares CHAR values using blank-padded comparison semantics.
Where as the VARCHAR2 datatype stores variable-length character strings, and Oracle compares VARCHAR2 values using nonpadded comparison semantics.
This is important when comparing or joining on the columns having these datatypes;

Anyone know why uploads contacts disappear from the iPhone 5?
Half of my number is suddenly gone, and this happens over and over again?
Kata-*******-stroff! Grateful for answers?

do you sync your contacts with an application in your computer? or use iCloud?
I can't tell you why the contacts disappear but you can get them back without much hassle by syncing through iTunes with your computer.
do you regularly make backups? if so, you can restore your iPhone using the backups and get your contacts back in your iPhone.
It is strange that half of your contacts are gone over and over again. Do you have Groups that are unchecked in your iPhone? If so, the contacts in those groups will not appear in your contacts list but they are in your iPhone and be recovered by re-checking the group name.

Help changing all PK and FK datatypes from uniqueidentifier to nvarchar(128)

Is there a simple script to iterate through all my tables and change my PK and FK datatypes to nvarchar(128)? I don't want to have to go through each table manually, remove relationships, and change each key one by one. Here is my db schema if it helps.

Hi Man_Cat,
According to your description, you are looking for the script to update all the PK and FK datatypes from uniqueidentifier to nvarchar(128), right?
Based on my research, we cannot change the data type of the Primary Key and Foreign Key directly as Tom said. However, we can drop the PK and FK and recreate them use the query below.
--This will drop the primary key temporarily
ALTER TABLE MyTable
drop CONSTRAINT PK_MyTable
--change data type
ALTER TABLE MyTable
ALTER COLUMN PrimaryKeyID BigInt
--add primary key
ALTER TABLE MyTable
ADD CONSTRAINT PK_MyTable PRIMARY KEY (PrimaryKeyID)

since decimals are also there in your data....You're right! I missed that.
select REGEXP_SUBSTR ( val1, '[[:digit:]]+\.?[[:digit:]]+')that requires there to be at least one digit before the decimal point and at least one digit after the decimal point.
Even worse, it ignores single-digit numbers unless they are followed by a decimal point and at least one more digit.
Unfortunately, to really check for numbers (including optional decimal points) is much messier.
For example:
TO_NUMBER (REGEXP_SUBSTR ( columna
                      , '[+-]?'          ||     -- Optional sign
                  '('               ||     -- choice: either
                    '[0-9]+'     ||     --   (1) 1 or more digits
                    '\.?'          ||     --         then an optional decimal point
                        '[0-9]*'     ||     --         then 0 or more digits
                  '|'               ||     -- or
                    '\.'          ||     --   (2) a decimal point
                    '[0-9]+'     ||     --         followed by 1 or more digits

How do I upload the contacts from my iPhone 5S to the Bluetooth device on my Toyota RAV4? The car manual says to consult the phone's Bluetooth instruction manual, but I don't have a manual for that.

That is very strange... I wonder if it has something to do with the firmware or some sort of error. I haven't ran into this but at the shop I work at I've ran into several firmware errors on iPhone 4 all the way through the 5s. Maybe its something as simple as putting a different part of the code into iTunes... I know you can something of this extent. I would look up error 1669, I know you have tried a number of things but look it up on the forum and see what fixes are available so that you may be able to restore it properly without all this garbage you are running into. Just a thought for you.

Problem in the BDC program to upload the data from a flat file.

Hi,
I am required to write a BDC program to upload the data from a flat file. The conditions are as mentioned below:-
1) Selection Screen will be prompted to user and user needs to provide:- File Path on presentation server (with F4 help for this obligatory parameter) and File Separator e.g. @,#,$,%,... etc(fields in the file will be separated by using this special character) or fields may be separated by tab(tab delimited).
2) Finally after the data is uploaded, following messages need to be displayed:-
a) Total Number of records successfully uploaded.
b) Session Name
c) Number of Sessions created.
Problem is when each record is fetched from flat file, the record needs to be split into individual fields separated by delimiter or in case tab separated, then proceeding in usual manner.
It would be great if you provide me either the logic, pseudocode, or sample code for this BDC program.
Thanks,

Here is an example program, if you require the delimitor to be a TAB, then enter TAB on the selection screen, if you require the delimitor to be a comma, slash, pipe, whatever, then simply enter that value. This example is simply the uploading of the file, not the BDC, I assume that you know what to do once you have the data into the internal table.
