mapping error between fields specified and columns selected
This error message is issued by ndlm during an export operation when there is a problem mapping fields in the RECORD section with columns in the SELECT statement. One of three possible secondary messages is included, specifying the exact nature of the problem:
Number of fields specified exceeds number of columns selected
There are more fields in the RECORD section than columns referenced in the SELECT statement, so one or more fields are not used.
Selected columns contain duplicates
The SELECT statement projection list includes multiple references to the same column.
Field specified doesn't map to selected columns
A field in the RECORD section is not specified as a column in the corresponding ordinal position in the SELECT statement projection list.
