db_bind_t::data_ind For absolute bindings, the memory address of the field length indicator. For relative bindings, the memory offset of the field length indicator. The field length indicator is a value of type db_len_t that provides information about the length of the field when stored in the database. The length indicator is optional, and can be disabled by setting data_ind to 0. When data is fetched from the database, the length of the field is stored in the length indicator. This enables access to strings that are not NULL terminated. If the field is NULL, the value DB_NTS will be stored in the length indicator. When data is written to the database, the length indicator provides instructions on how to use the bound memory buffer. The following values are permitted: A non-negative number - Length of the data to write. DB_FIELD_NULL - Indicates that the field is NULL. DB_NTS - Treat field as a NULL-terminated string. DB_AUTOFIELD - Manage length automatically.
