Oracle Error Codes

value too large for column string (actual: string, maximum: string)

An attempt was made to insert or update a column with a value which is too wide for the width of the destination column. The name of the column is given, along with the actual width of the value, and the maximum allowed width of the column. Note that widths are reported in characters if character length semantics are in effect for the column, otherwise widths are reported in bytes.

How to Solve :

Examine the SQL statement for correctness. Check source and destination column data types. Either make the destination column wider, or use a subset of the source column (i.e. use substring).
