Oracle Error Message
SQL*Loader-00426: count of elements in VARRAY string comes after the data for the varray
Reason for the Error
The COUNT clause for a VARRAY field indicates that the count of elements in the varray is stored in another data field. However, that data field comes after the varray data in the data file. Since finding the count field would require SQL*Loader to know the number of elements in the VARRAY first, SQL*Loader requires that the count field come before the VARRAY data.
Move the count field to be before the collection data in the data file.
