Data Types Handling Troubleshooting

One rare item that has the potential to cause issues during export to an Oracle Database relates to a differing in how datatypes are handled between Data Prep and Oracle Database. Data Prep is designed to handle columns with mixed data types, where Oracle is not. Data Prep determines a column data type based on the predominant data type present in the column. This becomes an issue when Data Prep identifies the datatype in a column is boolean and exports the column as a boolean even though it still contains mixed datatypes. This should be addressed in Data Prep before exporting to Oracle.
