Oracle Error Message
SQL*Loader-00307: Warning: conflicting lengths number and number specified for column string table string
Reason for the Error
The SQL*Loader control file specifies two different lengths for the named column. There are three ways to specify the length of a field: –with the POSITION keyword: POSITION(1:3) — with the length specifier: CHAR(6) — with the implied length of a datatype; for example, INTEGER — A conflict could occur between any two of these specifications (or among all three, but only two are shown). A common cause of this error is the specification of some numeric datatype, such as INTEGER, when the numeric external form is intended (INTEGER EXTERNAL). The external form consists of character data, so it is considerably longer than the numeric form, which consists of binary data.
No action is necessarily required, because SQL*Loader uses only one of the lengths. Check the log file under the heading “Len” in the table-description section to see which length was used. Adjusting the SQL*Loader control file to produce uniform length specifications will remove the warning.
