+### Mapping Spark SQL Data Types to Oracle
+
+The below table describes the data type conversions from Spark SQL Data Types
to Oracle data types,
+when creating, altering, or writing data to an Oracle table using the built-in
jdbc data source with
+the Oracle JDBC as the activated JDBC Driver.
+
+<table>
+ <thead>
+ <tr>
+ <th><b>Spark SQL Data Type</b></th>
+ <th><b>Oracle Data Type</b></th>
+ <th><b>Remarks</b></th>
+ </tr>
+ </thead>
+ <tbody>
+ <tr>
+ <td>BooleanType</td>
+ <td>NUMBER(1, 0)</td>
+ <td>BooleanType maps to NUMBER(1, 0) as BOOLEAN is introduced since
Oracle Release 23c</td>
Review Comment:
we might introduce a configuration for users to map BOOLEAN instead.
