| SQL_COLUMN_DISPLAY_SIZE | For LONGVARBINARY data, SQL_COLUMN_DISPLAY_SIZE is the maximum length of the column, not the maximum length of the column times 2. |
| SQL_OWNER_NAME | An empty string ("") is returned in this column because owner name is not supported. |
| SQL_QUALIFIER_NAME | The path to a directory is returned. |
| SQL_COLUMN_SEARCHABLE | LONGVARBINARY and LONGVARCHAR columns are reported as SQL_UNSEARCHABLE. Fixed-length and variable-length binary and character data types are searchable, even though LONGVARBINARY and LONGVARCHAR are not. |
