1. A method of copying data in a table from a source database to a target database, the method comprising: copying data from the table in the source database into a conflicts schema; determining whether a table definition for the table in the source database dictionary is compatible with a table definition for the table in a target database dictionary; executing a first INSERT/SELECT statement to copy data from the table in the conflicts schema to a target schema of the target database; in response to a determination that the table definition for the table in the source database dictionary is not compatible with the table definition for the table in the target database dictionary: rolling back the first INSERT/SELECT statement execution in response to a determination that the data from the first INSERT/SELECT statement did not fit in the table in the target schema of the target database; executing a second INSERT/SELECT statement including a WHERE clause to copy data from the table in the conflicts schema to the target schema of the target database; in response to a determination that the second INSERT/SELECT statement did not copy data from the table in the conflicts schema to the target database, executing a third INSERT/SELECT statement forcing the data to fit in the table in the target schema of target database.
