This should be called after you are done with any database allocated through duckdb_open.
Note that failing to call duckdb_close (in case of e.g. a program crash) will not cause data corruption.
Still it is recommended to always correctly close a database object after you are done with it. duckdb_column_count ⚠ Returns the number of columns present in a the result object. duckdb_column_data ⚠ DEPRECATED**: Prefer using duckdb_result_get_chunk instead. duckdb_column_logical_type ⚠ Returns the logical column type of the specified column. duckdb_column_name ⚠ Returns the column name of the specified column.
