Hi,

I need to update the existing data in the table from the contents of a flat file.
Can anyone let me know what is the option to be used with sqlldr?
I get as many as 100K records for update.

Thanks
Jyo

no, but you could make the flat file to be an external table & use UPDATE statement. This advice assumes a correct WHERE clause exists.

Thanks for the reply.
Do you mean that I need to load the file into a seperate table[B] and then update the existing table[A] using the data in the table[B] ?

I suggest you use the Search capability on the forum for "external table" and/or use GOOGLE for same string plus "oracle".

If the flat file resides on the database server system, Oracle can treat this file as though it is an internal table.

Thanks I am new to Oracle so I thought external table is a new table.
