The cci_col_seq_put function replaces the index-th (base:1) member of the sequence attribute values with a new value. The following example shows how to replace the first member of the sequence attributes values with "a".
cci_col_seq_put(con_id, oid_str, seq_attr, 1, "a", err_buf);
intcci_col_seq_put (int conn_handle, char *oid_str, char *col_attr, int index, char *value, T_CCI_ERROR *err_buf)
