Types in the C API are modeled using an enum ( duckdb_type ) and a complex class ( duckdb_logical_type ). For most primitive types, e.g., integers or varchars, the enum is sufficient. For more complex types, such as list...s, structs or decimals, the logical type must be used. typedef enum DUCKDB_TYPE { DUCKDB_TYPE_INVALID = 0 , DUCKDB_TYPE_BOOLEAN = 1 , DUCKDB_TYPE_TINYINT = 2... - https://man.mtool.work/duckdb/1.3/clients/c/types.html
