How to change the location of a column in a Oracle table?

Sir:
I want to add a new column in a table, but I dont want to add the column at the last of the table, how can I do it ? If I want to modify the locations of columns in a table, How can do it?
Thanks

You can't modify the order of columns in a table, though there shouldn't be any particular reason to care about the order of columns.
You can always create a view over the table that SELECT's the columns in the order you want, though.

Putting a .pdf file into a column in an oracle table

I have created a table with one column as a blob so I can put 4800 .pdf files into that column of a table. Can anyone correct the ways I am trying to do this or let me know of a better way. I have tried several ways and have not been successful. Thanks.
Here are the two ways I have tried that haven't worked.

Resize a blob column in an Oracle table

I have a table that store pictures from inspections. Occasionally, I will get a 3 or 4 mg file that Oracle Reports will not produce a report because of the size of the photo.
Is there code to resize a blob?

Hi,
Not sure what you mean by "resizing" a blob. You can extract and return a substring of the blob using the dbms_lob supplied package:
SQL> -- get the first 2000 bytes
SQL> select dbms_lob.substr(<blob_column>,2000,1) from <blob_table>;but given the nature of your data, I highly suspect that would be of any use to Oracle Reports or any frontend for that matter.
If by "resizing" a blob, you mean "change the resolution of the pic (blob), on the fly, so that it occupies less space", then I doubt it would be easy to implement using SQL or even PL/SQL.
Just a thought - you may want to program the image resizing logic in a language like Java or C and implement it as a Java Stored Procedure or call it as an external procedure respectively.

Column not found error while populatin a oracle table with ODI USer

Hi,
I am trying to populate a column in a oracle table with the ODI USER name using the function getUser("USER_NAME") in the Mapping column of the Interface, But the interface throwhing an error *Column not found : Supervisor in Statement [Select......]*. but it's working fine with getUser("I_USER') the column is populating the user identifier.
can any one help me out why user is not populating.
Thanks

Enclose the call to the getUser api inside single quotes
'<%=getUser("USER_NAME")%>'ID being a number can be used directly but USER_NAME returns a string that needs to be quoted

How to create hidden column in Oracle Table

Hi folks
i have one doubt regarding hidden column creation in Oracle Table..
Let me briefly explain my requirements.
I have one table called UWRMC_MAST is table contain the following columns
        RMC_N_ID           NUMBER(10)                    NOT NULL,
     COB_N_ID           NUMBER(2)                      NOT NULL,
     SUBCOB_N_ID     NUMBER(2),
     RMC_C_CODE      VARCHAR2(10 BYTE)         NOT NULL,
     RMC_C_NAME      VARCHAR2(100 BYTE)       NOT NULL,
     CREATED_N_BY   NUMBER(10)                     NOT NULL,
     CREATED_D_DT   DATE                              NOT NULL,
     MODIFIED_N_BY NUMBER(10)                     NOT NULL,
     MODIFIED_D_DT DATE                              NOT NULL,
     RECORD_N_STS   NUMBER(1)                      NOT NULL,
     RMC_C_REMARKS VARCHAR2(256 BYTE),
     EFFECT_D_DT     DATE                           NOT NULL
RMC_N_ID is primary key
i want to create one column like Old_EFFECT_D_DT as virtual column
when ever i update the effective date that date should be insert into Old_EFFECT_D_DT i.e., Virtual Column
For example
SQL> select RMC_N_ID, COB_N_ID, SUBCOB_N_ID, RMC_C_CODE, EFFECT_D_DT from uwrmc_mast;
RMC_N_ID   COB_N_ID SUBCOB_N_ID RMC_C_CODE EFFECT_D_
        46          1          74 PCTMOTR    02-FEB-11
Below i update the effective date(01-feb-2011
SQL> update uwrmc_mast
2 set EFFECT_D_DT = '01-apr-2011'
3 where rmc_n_id =46;
1 row updated.
But i want a result like below
SQL> select RMC_N_ID, COB_N_ID, SUBCOB_N_ID, RMC_C_CODE, EFFECT_D_DT from uwrmc_mast;
RMC_N_ID   COB_N_ID SUBCOB_N_ID RMC_C_CODE EFFECT_D_   OLD_EFFE
        46          1          74 PCTMOTR    01-APR-11   02-FEB-11Is this possible to do in oracle , kindly give a solution for my requirement

Regards,
ArunWell, I'm not sure exactly what your requirement is.
If you want to audit changes to the records of that table then it would be better to use Oracle's auditing facility. If this previous change date is really a required part of your actual application functionality then you might use the application itself to maintain the previous date as a column in the table, as you say, or if you need to maintain the history of changes then add a new table so you can keep track of multiple changes.

How to transfer a string with \' and \" to an Oracle table?

An MS Access column contains characters such like \' and \". How to transfer this column to an Oracle table? Thank you.
sqlCommand="insert into jobposition values (\'"+rsSrc.getString(1)+"\')";

Sure, as a Java programmer, I undertand
(1) All of \\, \' and \" are single characters,
but here you have to understant
(2) I'm making a SQL command (not a java statement!) with ' or " (not \) !!!
Please pay attention, I don't need \, I need ' ONLY!
So, the following sqlCommand can be run properly.
aString="programmer bad boss";
sqlCommand="insert into mytable values (\'"+aString+"\')";
But, the following sqlCommand can NOT be run properly?
aString="programmer\'s \"bad\" boss"; // programer's "bad" boss
sqlCommand="insert into mytable values (\'"+aString+"\')";
DO NOT tell me you want to modify them like this:
aString="programmer\'s \"bad\" boss"; // programer's "bad" boss
sqlCommand="insert into mytable values (\\'"+aString+"\\')";
PLEASE!
(If so, you can't get a correct SQL command!
Note: an incorrect SQL command is shown as following:
insert into mytable values (\'programmer\')
The \\ will give you a single \ in your String.
The \ is an escape character so in a String you must
double them.

Regards,

Hi Gyan,
The error reads The value for field "ACTUALWEIGHT_LASTDIE" is invalid. Value cannot be null.
You need to ensure below things:
1) Ensure that all the columns in the oracle table allow NULL.
2) The field which is getting the error should have property Nillable set to True and Min Occurs = 0.
3) You also need to configure your WCF_Oracle adapter properly i.e. SOAP Action (see for instance this
thread).
Why SOAP Action?
If you used the default bindings which were created when generating your schema, they are usually created wrapped within an operation.
Unless the send port within your orchestration's operation matches the same name as the enclosing operation tag in the "SOAP action header" sending messages using the default setting will fail.
So to ensure that your send port works just supply a URL for the "SOAP action header" setting.

More than one SDO_GEOMETRY columns in one Oracle 8i spatial table

I have a spatial table as follows:
CREATE TABLE TEST(
ID VARCHAR2(255) NOT NULL,
POINT MDSYS.SDO_GEOMETRY,
LINE MDSYS.SDO_GEOMETRY,
POLYGON MDSYS.SDO_GEOMETRY,
PRIMARY KEY(ID));
Is it a good practice to have more than one SDO_GEOMETRY columns
in one spatial table? What are the drawbacks if any to have a
spatial with more than one layer?

I have one question about more than one SDO_GEOMETRY columns
in one table in Oracle 8.1.7. When I wanted to create two
spatial indices for this table, every time I got some error.
Can anyone tell me how to figure it out?
Thanks very much,
Fan Fan,
You need to insert metadata record before creating spatial
indices.
Try the following:
REM USER_SDO_GEOM_METADATA :
REM insert a row for the geom layer for TEST TEST2 tables
REM
INSERT INTO USER_SDO_GEOM_METADATA
( TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
VALUES ('TEST', 'POINT', MDSYS.SDO_DIM_ARRAY
(MDSYS.SDO_DIM_ELEMENT('LON', -180,
180, .000005),MDSYS.SDO_DIM_ELEMENT('LAT', -90, 90, .000005)),
NULL);
INSERT INTO USER_SDO_GEOM_METADATA
( TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
VALUES ('TEST', 'LINE', MDSYS.SDO_DIM_ARRAY
(MDSYS.SDO_DIM_ELEMENT('LON', -180,
180, .000005),MDSYS.SDO_DIM_ELEMENT('LAT', -90, 90, .000005)),
NULL);
INSERT INTO USER_SDO_GEOM_METADATA

180, .000005),MDSYS.SDO_DIM_ELEMENT('LAT', -90, 90, .000005)),

REM create a spatial index based on TRAFFIC.GEOM

Uploading a file (.doc, .xls, .txt) into an Oracle table with BLOB column

Hello All :
I have been trying to figure out for a simple code I can use in my JSP to upload a file (of any format) into an Oracle table with a BLOB column type. I have gone through a lot of existing forums but couldnot find a simple code (that doesnot use Servlet, for eg.) to implement this piece.
Thanks a lot for your help !!

Hi.
First of all to put a file into Oracle you need to get the array of bytes byte[] for that file. For this use for example FileInputStream.
After you get the byte array try to use this code:
        try {
            Connection conn = myGetDBConnection();
            PreparedStatement pstmt = conn.prepareStatement("INSERT INTO table1 (content) VALUES(?)");
            byte[] content = myGetFileAsBytes();
            if (content != null) {
                pstmt.setBinaryStream(0, new ByteArrayInputStream(content), content.length);
            pstmt.close();
            conn.close();
        } catch (Exception ex) {
            ex.printStackTrace();
        }or instead of using ByteArrayInputStream try pstmt.setBinaryStream(0, new FileInputStream(yourFile), getFileSize());Hope this will help...

How to Load file name in to Oracle table column

hi,
I am loading data from flat file(TEST_GRET.DMP) to oracle table.
while the Target Oracle table has four coloumns, in which one is File_name.
I want to load the FILE NAME into that table too. as there is no ????
how it can be done???
Regards,

If you are loading multiple files using a single interface, using variables, Bhabani's first solution and my solution are good.
If you only have one interface with your datastore, you know the file name and it won't change, you can use Bhabani's second solution or mine.
I did not test my solution but it is quite simple to test.
Just put the code provided for the mapping of your target column.
This solution has the advantage it should always work.

I believe you need to use 'trailing nullcols' as a parameter in your sql loader command.
See example below:

Data Type for a Longitude/Latitude Column in an Oracle dB Table?

Greetings All,
What is the recommended data type for a Longitude(Lon) or Latitude(Lat) Column of an Oracle dB Table? I am creating a signs inventory table in our Oracle database to be used as a data warehouse for our signs inventory. The Lon and Lat fields along with some other data will be populated from a MS access file exported from our Geodatabase. Currently the data type for the Lon and Lat fields of the MS access file is defined as "Double". A couple of Examples of the Lon and Lat data are as follows:
Lat                       Lon
59.4564555909     -135.3133542922
64.841125            -148.01808
...What data type should these two columns be defined in the new Oracle database table??? Should the data type be defined as FLOAT(126), NUMBER(10, 6), or else? Any suggestions/help on this would be greatly appreciated.
If the data type is defined as NUMBER(10,6), the first example of Lon "-135.3133542922" will be truncated to "-135.313354" or would I receive an error while trying to import the data from an access file to the Oracle dB?
Thanks in advance for any/all the help.

Orchid,
Is SDO_GEOMETRY available in Oracle 10g?Yup. I'm still on 10g as well; there's no shame in that.
How do I format my lat/long's into WKT and use the SDO_GEOMETRY constructor?The March 16th example shows the steps, but I take it you're trying to get your data from MS Access into Oracle. Is that right? If so, consider these options:
OPTION 1, When you have < 50k records
Simply write a query that returns INSERT statements that you can run against Oracle.
For example, let's say you have a table in MS Access defined as msaCoords (ID, LongX, LatY).
Let's say, your destination table in Oracle is named oraCoords(ID NUMBER, Geometry MDSYS.SDO_GEOMETRY). Then,
SELECT "INSERT INTO oraCoords (ID, Geometry) VALUES (" & ID & ", SDO_GEOMETRY('POINT (" & LongX & "," & LatY & "'), 8307);" FROM msaCoords;
-- "MS-ACCESS QUERY RESULTS"
INSERT INTO oraCoord (ID, Geometry) VALUES (1, SDO_GEOMETRY('POINT (-135.3133542922,59.4564555909'), 8307);
INSERT INTO oraCoord (ID, Geometry) VALUES (2, SDO_GEOMETRY('POINT (-148.01808,64.841125'), 8307);Save those MS-ACCESS QUERY RESULTS to a text-file (D:\MyPts.sql). Launch SqlPlus and type @D:\MyPts.sql
Once it's done, type Commit into SqlPlus and you're done.
OPTION 2, when you have > 50k records
Use SqlLoader. There's an example posted { here | http://forums.oracle.com/forums/thread.jspa?messageID=9412123&#9412123 }
Cheers,

Insert single column into oracle table

i have a table t1 in whcih only one column is there
Create table t1
a number);now i need to load this column from a excel sheet.
it have many rows and many column but need only corresponding column.
please suggeest any way apart from external table and sql laoder.
thanks

No problem if you have thousands of rows.
Say the value you want to insert is in column A of your excel file.
In column B use the following formula:
=CONCATENATE("insert into t1 values (";A1;");")And copy this formula to all other rows.
Then select all the B column, copy it and paste it in a notepad file.
Call the file as you want, for example c:\ins.sql
open sqlplus and run
SQL> @c:\ins.sqlAt the end don't forget to commit...
