SQL & PL/SQL :: How To Fetch Value Which Column Has Timestamp Datatype
Oct 14, 2012
i am running one query which is here
INSERT INTO shiftsample (Empid, PPDate, Inpunch, outpunch)( SELECT Emp_ID, PDate, In_Punch, Out_Punch FROM ProcessDailyData WHERE PDate = to_char(2012-10-15,'yyyy-MM-dd') AND Emp_ID = '00000001' );
in this query pdate has timestamp datatype and in shift sample ppdate column has date type. so i am not able to insert value from process daily data table.
getting this error.
SQL Error: ORA-01481: invalid number format model
01481. 00000 - "invalid number format model"
*Cause: The user is attempting to either convert a number to a string
via TO_CHAR or a string to a number via TO_NUMBER and has
supplied an invalid number format model parameter.

ProdID||ProdRequestID ||EVENTTIMESTAMP

on this query. I need to get a particular value from a column which is a BLOB datatype. Here is the sample
data ID TESTDATA1 Best Buy
00001234 12222 30 00 2
Lowes 00001234 12222 100 00 3
Walmart 00001234 12222 129 00 4
abc 00001234 12222 5000 00 5
Toshiba 00001234 12222 21 00 6
abcdefghij 00001234 12222 49 00
Where '00001234' is the Invoice , '12222' is Netamount field and highlighted in red is the $ amount for that invoice.
The only data i need query to return 12222 (netamount)= $amount. I tried using substr select substr((TESTDATA),19,26)test from TABLEA; But this gives me the only the first row but not other amount which have different positions.
Here is the desired output
OutputID TESTDATA 1
12222 30 2 12222 100 3
12222 129 4 12222 5000 5
12222 21 6 12222 49

I have a table A with a column B timestamp(6). The tables contains around 300000 rows..I have created index 'idx' on the column B.When i compare column 'B' with systimestamp, it does not use the index, whereas if i compare 'B' with sysdate it uses the index.
Eg :
select count(*) from a where b<=sysdate;
The above used the index 'idx' and executed in 1 second
select count(*) from a where b<=systimestamp;
The above does not use the index and executed in 19 seconds.

Due to some business requirements a table field needs to change from date to timestamp in order to handle the millisecs.
1>When i alter the row , for a table with 150 million recs will there be a conversion. Is there a recommended way to convert the field. Mind you this field is used as a part of composite PK.
2> There is a interfacing application which connects and copies the data to its system and is using the date type, will that application be able to continue to work without any changes, if it does not care about the millisecs.
3> Will there be performance impact on an existing application that uses the date field to sort
4> Will DB need more space due to the change

I have a table defined where some columns are of the datatype RAW(16). In fact these are foreign keys to other tables. Our company has a policy that all primary keys are of the datatype RAW(16). Not much I can do about that.
Now I want to retrieve all columns of a certain row in that table and just visualize the foreign keys in hex format. All values are filled out nicely, except the columns with datatype RAW(16). Is there something special I have to do to retreive and display these? I defined an item as text-field for these, but this doesn't seem to be working...
I'm using APEX 4.1.1.00.23 at this moment...

I have to change the datatype of a column from CLOB to varchar2, without changing the order of the columns. The table has no data.
I could find any other way other than dropping the CLOB columns and then adding new columns with varchar2 datatype. But this changes the order of the columns in the table.

I have a table that has column with BLOB datatype. I am trying read only the inputted String from the BLOB datatype column. I have used the below query,
SELECT utl_raw.cast_to_varchar2(column1) FROM TAB1
and it gives the result as
<H2><FONT color=#cc0000><EM><U>test</U></EM></FONT></H2>
However I would like to extract only the string "test" which is inputted. Is there any build-in function in oracle which will satisfy this requirement?

fields terminated by "," optionally enclosed by ' " '
(src_id,dest_id,range,payload)

When I use the following this ctl file to transfer the data, i get the following error:
