DATA TYPES IN ORACLE

I am new to Oracle, and I would like toknwo how do you do the following?
Implement a boolean type column (True/False).
Implement a time colum.
How do you set a dafault value for column?
Thanks

All data types are explained in chapter 2 of the SQL Reference manual.
This includes a complete list of available types, the internal representation, formatting options (for dates and numerics), and so on. It varies by version - the docco is generally available through http://docs.oracle.com and for 10g Release 2, the docco is at
http://www.oracle.com/pls/db102/portal.portal_db?selected=1
Direct answers
- there is no Boolean type.
- the Date datatype is defined as "Century Year Month Day Hour Minute Second". Although most sessions and defaults simply display the year, month and day, the time portion is still included. This has been known to throw off people when doing selects, as the time portion IS included and implied.
- the default value for a column can be managed in the create table or alter table command.

Pdf file stored as BLOB data type on Oracle

I store PDF file as BLOB data type on Oracle. There are cases
where I get multiple records from the database, that means I get
multiple PDF files. They have to be merged and displayed on the web
page. I tried CFContent which can display only one PDF file at a
time but not more than one, whereas cfdocument is having problem
converting binary data to string. I am kind of stuck.
Can you anybody please help me out? Please let me know if you
have any questions or this does not make sense to you.
Thank you in advance.

if by "merge" you mean 3 pdf into 1 pdf, try cfpdf (if on
cf8) or see this

Hi,
I think you need unique ID's, for this purpose you use sequences
in Oracle. Example:
create table xy (
id number,
name varchar2(100)
alter table xy
add constraint xy_pk primary key(id);
create sequence xy_seq start with 1 maxvalue 99999999999;
(there are many other options for create sequence)
create or replace trigger xy_ins_trg
before insert on xy
for each row
begin
select xy_seq.nextval
into :new.id
from dual;
end;
This produces a unique value for the column id at each insert.
Hope this will help.

Cannot get the correct data type in Oracle JDBC

Dear ALL:
I used JDBC ResultSetMetaData to get the column data type for Oracle Database. I created a table including 2 columns AAA, which is NUMBER type, BBB which is FLOAT type.
However, I found a problem that either NUMBER or FLOAT data types are reported as NUMBER type in JDBC.
IN SQL 2000, it is okay. SMALLINT, INT, TINYINT, etc..can be reported correctly.
Can anybody tell me that what's wrong here? I will be very appreciated.

hi,
i guess its a bug which is fixed with 10i.

XML Data Type in oracle

I am a developer in .NET with having experience working on SQL server.
I want to know whether there is an xml data type in oracle.
I have an xml in my front end and want to insert record in the database for the values inside that xml. What i am doing currently is that i am retreiving the value in the xml in the .NET code and passing the values a parameter to a stored procedure in oracle. what i want to do is to pass the xml directly to stored procedure in oracle and retrieve the values there (using Xquery) and insert the records.
This is possible with SQL server 2005. I want to know is this possible with Oracle.
Thanks and regards,
Sameer J Narkar

Wonderful - a documentation question!
You will find your answer by going to the general documentation portal at http://tahiti.oracle.com following the path to the database version of interest, and looking in the SQL Reference manual. Chapter 2 discusses all data types, including the several supported for XML.
In addition, under the 'Books' tab, there are several XML-developer specific reference manuals.
(Oracle's support for XML generally blows away the others. The price for the extreme flexibility is an ease-of-use hit.)

BOOLEAN data type in oracle is it there?

is there any data type in oracle which stores BOOLEAN data?

>
There are inevitably problems with three-valued logic. To be consistent with the 3VL world of SQL one would expect a 3 value logical type (not strictly a "boolean" type at all). The standard chose not to do that and opted for just TRUE and FALSE with NULL as a sort of substitute for the third value. That in itself creates some logical conundrums but it's probably impossible to come up with any system that makes sense of SQL's 3VL. Probably that's why most DBMS vendors leave it out.
>
No problem. Just define it as NOT NULL and you will have traditional 2VL Boolean algebra.

....Date Type in Oracle

Hi All,
Just to clear a few misconception/ambiguities regarding the DATE data type in Oracle.
We hve a table which stores the date of insertion of a record. The front end application is in PHP while backend is in oracle.
When i query the table, it shows the date as dd-mon-yy , but it does not show the time. I have tried to query it throgh sqlPLus , TOAD and the PHP Application, but it doesnt show the time.
Is it not storing the time. The data type of the column is ( Insertdate date).
If you query sysdate, it definitly stores time, ... but what is in this case. Is it just storing the date and not the time. ???
How to alter so that it stores time as well.
Regards

U have to use the conversion function to_date to
store date along with time. No, you use to_date to convert a string to a date. That's it. A date column will ALWAYS store the time (it just won't always display it)
When u need to retrieve the data use to_char function. Not necessarily:
SQL> create table x (dte date);
Table created.
SQL> insert into x values(sysdate);
1 row created.
SQL> insert into x values(sysdate+1);
1 row created.
SQL> select * from x;
DTE
11-jul-2007 09:13:11
12-jul-2007 09:13:11
if u want to store time u can use timestamp data typeNope, You use timestamp if you want to store fractions of seconds (down to nano seconds)
The key point is. The date datatype ALWAYS stores:
Century, Year, Month, Day, Hour, Minute, Second

Problem loading PostgreSQL Bytea data type to Oracle Raw data type

We are migrating our database from PostgreSQL to Oracle. First, we convert the BYTEA data type in PostgreSQL to Oracle RAW. The BYTEA data type is variable bytes array. How can we load the BYTEA data type to Oracle RAW data type? Or I have to convert to different data type. thanks.
Peter,

hi,
Instead of 'interval day to second' in method declaration use internal datatype 'DSINTERVAL_UNCONSTRAINED'.
There are more unconstrained types in oracle.

How to add a new data type of oracle to SIM(7.0)

Hi........
I need to add a new data type(CLOB) to SIM of oracle .can anyone tell me how to modify or add this new data type.
Any pointers to this will be highly appriciated.......
thax in advance...

Hi,
Easiest way is to download the table eg into an Excel table (if possible) or text table. Drop the table from the database. Build your table with the new key field. Build the database table again and fill it.
You can do it also over the database into a new table. Drop the old one. Build the enhanced one and fill it. Afterwards drop your (temporary) table.
Maybe there are other ways, but this works.
Success,
Rob

ORDImageSignature Invalid data type in Oracle 8i

hi there,
i have just started working on Intermedia, i am using Oracle 8i. i have configured the intermedia and executed the ordwebutl.sql file. all othe media data types are working perfectly like, ORDAudio, ORDImage,ORDVideo, but the ORDIMageSIgnature is not working at all. when i use it as data type in any table it says Invalid data type. which means oracle 8i is not recognizing ORDImageSIgnature at all. plz help me as soon as possible. Thanks in advance.

The ordimagesignature is not something you can see or hear. It is strictly binary metadata about the image, used only to compare images to each other.
What are you trying to do?

Migrating Sybase "timestamp" data type to Oracle DB

Hi,
We are migrating huge Application currently running on Sybase database
to Oracle 10.2.0.3 (500+ Tables and Stored Procedures).
Have following questions regarding this Migration.
1) Many of the Sybase Tables have column which is of Sybase data type "timestamp".
Do you have any recommendation what is the data type to be used in Oracle for
migrating "timestamp" data type in Sybase?
2) How should we migrate existing data and business logic residing in Sybase for
data columns of Sybase data type "timestamp" ?
Given below are details on how we use Sybase timestamp Column in our Application
and we are trying to arrive at the best Solution that is possible for migrating
all those Tables and related business logic to Oracle.
We have following Control Table in Sybase which has column of timestamp data type and
some other Business keys.
sp_help EQP_IES_CRE_TIMESTAMP (This is similar to desc <table> command in Oracle)
EQP_IES_CRE_TIMESTAMP,dbo,user table
default,Nov 14 2001 10:39AM
CRE_TIMESTAMP ,timestamp,8,,,0,,,,0
REF_NUM ,char,30,,,0,,,,0
REC_UPD_DT ,datetime,8,,,1,,,,0
EQP_IES_CRE_TIMESTAMPI1,clustered, unique located on default, CRE_TIMESTAMP, REF_NUM, REC_UPD_DT,0,0,0,
Following is the overall logic used in Sybase
-- Step 1: Based on Event, populate Control Table with new Row.
-- CRE_TIMESTAMP timestamp Column gets auto-populated by Sybase
insert EQP_IES_CRE_TIMESTAMP (REF_NUM, REC_UPD_DT)
values (@uuid_ref_num, @event_cre_dt)
Since CRE_TIMESTAMP is auto-populated, it does not appear in above INSERT statement.
-- Step 2: Store timestamp value populated by Sybase in previous step,
-- to variable @event_timestamp. This value would be referenced
-- later in other SQL statements
select @event_timestamp = CRE_TIMESTAMP
from EQP_IES_CRE_TIMESTAMP
where REF_NUM = @uuid_ref_num
and REC_UPD_DT = @event_cre_dt
-- Sample value for @event_timestamp could be '001c0000182f2089'
-- It is not very readable or understandable
-- Step 3: Delete Control Table entry made in Step 1
delete EQP_IES_CRE_TIMESTAMP from EQP_IES_CRE_TIMESTAMP
where CRE_TIMESTAMP = @event_timestamp
-- Step 4: Make use of saved timestamp value from Step 2 to trigger queries
-- against other Tables that have timestamp Columns
-- Some sample queries are as shown below
delete eqp_staging
where event_timestamp > @event_timestamp;
insert into eqp_movement values(@event_timestamp, ......other columns) ;
Any idea how above Table and logic could be migrated to Oracle DB
We would also like to know how data values that currently exist
in Sybase Tables should be populated in Oracle .
Any suggestions or tips would be greatly appreciated
Thanks
Auroprem

Hi All,
Thanks for your responses.
We have decided on Solution to migrate "timestamp" Column from Sybase to Oracle, that is
specific to our Application needs.
Following is what we decided:
1) Create RAW Column in Oracle which would contain data Replicated from Sybase "timestamp" Column as is.
2) Create additional Column of INTEGER data type to store number equivalent of Sybase "timestamp" column
which would be more usable and consummable in Oracle as compared to RAW datatype.
3) Write Row-Level INSERT/UPDATE Trigger on migrated Oracle Table to populate INTEGER Column using
SQL Function TO_NUMBER(<raw_column_value>, 'xxxxxxxx').
4) Applications that access this Table, upon migration to Oracle, will now start referencing INTEGER Column
newly defined, and populated via Trigger.
Please let us know if you see any issues with this approach
Thanks

Stored Procedures with Date data types and Oracle

This should be easy.... But i keep getting the error:
[Macromedia][Oracle JDBC Driver][Oracle]ORA-06550: line 1,
column 7: PLS-00306: wrong number or types of arguments in call to
'RETRIEVE_TS' ORA-06550: line 1, column 7: PL/SQL: Statement
ignored
And I got it worked out to where i know it is a problem with
the way i am using the date data types in a stored procedure....
In the past i usually avoided calling procedures in Oracle
with date as the in type.... It is always easiest to let oracle
convert the string to a date.... Unfortunately now i am stuck with
having a date type in the procedure call.... So the question is:
WHAT IS THE PROPER WAY TO SUBMIT DATE/TIME STAMP IN A STORED
PROCEDURE?
The Oracle Procedure looks like this:
PROCEDURE retrieve_ts (
p_at_tsv_rc IN OUT sys_refcursor,
p_units IN OUT VARCHAR2,
p_officeid IN VARCHAR2,
p_timeseries_desc IN VARCHAR2,
p_start_time IN DATE,
p_end_time IN DATE,
p_timezone IN VARCHAR2 DEFAULT 'GMT',
p_trim IN NUMBER DEFAULT false_num,
p_inclusive IN NUMBER DEFAULT NULL,
p_versiondate IN DATE DEFAULT NULL,
p_max_version IN NUMBER DEFAULT true_num
AND the stored procedure call looks like this:
<cfset ed = Now()>
<cfset sd = #DateAdd("d",-lbt,Now())#>
<cfstoredproc datasource="CWMS"
procedure="cwms.cwms_ts.retrieve_ts"
returncode="no">
<cfprocparam type="inout" variable="unit" value="#unit#"
dbvarname="@p_units"
cfsqltype="cf_sql_varchar">
<cfprocparam type="in" value="MVS"
dbvarname="@p_officeid"
cfsqltype="cf_sql_varchar">
<cfprocparam type="in" value=#id.cwms_ts_id#
dbvarname="@p_timeseries_desc"
cfsqltype="cf_sql_varchar">
<cfprocparam type="in" value="#sd#"
dbvarname="@p_start_time"
cfsqltype="cf_sql_date">
<cfprocparam type="in" value="#ed#"
dbvarname="@p_end_time"
cfsqltype="cf_sql_date">
<cfprocparam type="in" value="#tz#"
dbvarname="@p_time_zone"
cfsqltype="cf_sql_varchar">
<cfprocparam type="in" value="0"
dbvarname="@p_trim"
cfsqltype="cf_sql_numeric">
<cfprocparam type="in" value=""
null = "yes"
dbvarname="@p_inclusive"
cfsqltype="cf_sql_numeric">
<cfprocparam type="in" value=""
null="yes"
dbvarname="@p_versiondate"
cfsqltype="cf_sql_date">
<cfprocparam type="in" value="1"
dbvarname="@p_max_version"
cfsqltype="cf_sql_numeric">
<cfprocresult name="ts_dat">
</cfstoredproc>
Text

Yeah.... One is a type INOUT ref cursor.... which is denoted
by the cfprocresult....
By the way:
Phil - the code example with a little tweaking worked fine on
my machine....
<<cfstoredproc procedure="test_pkg.test"
datasource="myDSN" returncode="no">
<cfprocparam type="IN" cfsqltype="cf_sql_timestamp"
value="15-JUN-2005">
<cfprocparam type="OUT" cfsqltype="cf_sql_varchar"
variable="v_out">
<cfprocresult name="rs1">
</cfstoredproc>
PROCEDURE test(
v3_out OUT ref_cur_type,
v1_in IN date default null,
v2_out OUT varchar2
IS
BEGIN
v2_out := TO_CHAR(v1_in, 'mm/dd/yyyy');
OPEN v3_out
FOR
SELECT *
FROM user
WHERE activation_date >= v1_in;
END test;
Why do i still get this error......
Here is what it looks like now:
PROCEDURE retrieve_ts (
p_at_tsv_rc IN OUT sys_refcursor,
p_units IN OUT VARCHAR2,
p_officeid IN VARCHAR2,
p_timeseries_desc IN VARCHAR2,
p_start_time IN DATE,
p_end_time IN DATE,
p_timezone IN VARCHAR2 DEFAULT 'GMT',
p_trim IN NUMBER DEFAULT false_num,
p_inclusive IN NUMBER DEFAULT NULL,
p_versiondate IN DATE DEFAULT NULL,
p_max_version IN NUMBER DEFAULT true_num
<cfstoredproc datasource="CWMS"
procedure="cwms.cwms_ts.retrieve_ts"
returncode="no">
<cfprocparam type="INOUT" variable="p_units"
value="#unit#" 
cfsqltype="cf_sql_varchar">
<cfprocparam type="IN" value="MVS"

cfsqltype="cf_sql_varchar">
<cfprocparam type="IN" value=#id.cwms_ts_id#

cfsqltype="cf_sql_varchar">
<cfprocparam type="IN" value="#sd#"

cfsqltype="cf_sql_timestamp">
<cfprocparam type="IN" value="#ed#"

cfsqltype="cf_sql_timestamp">
<cfprocparam type="IN" value="#tz#"

cfsqltype="cf_sql_varchar">
<cfprocparam type="IN" value="0" 
cfsqltype="cf_sql_integer">
<cfprocparam type="IN" value=""

null = "yes"
cfsqltype="cf_sql_numeric">
<cfprocparam type="IN" value=""

null="yes"
cfsqltype="cf_sql_timestamp">
<cfprocparam type="IN" value="1"

cfsqltype="cf_sql_integer">
<cfprocresult name="ts_dat">

</cfstoredproc>
If I truly am short a parameter, How do you specify the INOUT
sys_refcursor?

Domain for data type in Oracle 8i database

Hi Sir,
Does Oracle database supports domain creation for data type.
for example, can I create a domain called shorttext which is VARCHAR2(50). Then when I specify a data type for a column in table, then I just declare the column as domain.
eg. address SHORTTEXT;
--where SHORTTEXT is a domain.
How is this implemented in Oracle database and supported by front end tools like Oracle Developer 6.0.
Hope someone can provide some clear explanation on this.
Thanks.
