Hi,
[Quoted] [Quoted] I want to upload a protein sequence (read it as a string) which is [Quoted] sometimes greater than 4000 characters into a clob field in a table.
create table sequences
(
ID NUMBER NOT NULL, SEQUENCE CLOB NOT NULL,
);
The values are comma seperated inside a file:
Eg: sequence.txt
123,asdflkdflsdfsdlfksdlfkasdlsdflf.....(more than 4000)
2342,lkjkakdkfl...>4000
3234,alkldklakdf...
And there are about 2 million rows of data to be uploaded.
Could someone give me an efficient way of uploading this data. Could anyone give me a syntax of the control file to upload this data? Currently i am using the insert commands inside a perl script to upload this data but it takes hours to do this.
Most of the examples that i saw here are for uploading some lob or clob from a file (one clob entry per file)!
Please help..
Thanks,
Dina
