Function libduckdb_sys::duckdb_query [−][src]
pub unsafe extern "C" fn duckdb_query(
connection: duckdb_connection,
query: *const c_char,
out_result: *mut duckdb_result
) -> duckdb_state
Expand description
Executes a SQL query within a connection and stores the full (materialized) result in the out_result pointer.
If the query fails to execute, DuckDBError is returned and the error message can be retrieved by calling
duckdb_result_error
.
Note that after running duckdb_query
, duckdb_destroy_result
must be called on the result object even if the
query fails, otherwise the error stored within the result will not be freed correctly.
connection: The connection to perform the query in.
query: The SQL query to run.
out_result: The query result.
returns: DuckDBSuccess
on success or DuckDBError
on failure.
