我的firebird程序只接受几个bigint值的参数。当我从go调用这个过程时，程序参数类型为uint64，值大于max int32/2，存储为负数。如何将bigint/uint64值作为参数传递？

import (
   ...
    "database/sql"
    "github.com/arteev/firebirdsql"
)
...
type Data struct {
  Value uint64
  Sum   uint64
  Ts    time.Time
}
...
tx, _ := db.Begin()
st, err := tx.Prepare("execute procedure add_summary(?, ? ,? ,?, ?)")
if err != nil {
    tx.Rollback()
}
defer st.Close()
if _, err := st.Exec(ip, ifKey, port, data.Sum, data.Ts); err != nil {
  ...   
} else {
  ...
}
...

架构/表ddl片段：

CREATE TABLE ADM_SUMMARY (
    ITEM_ID  INTEGER NOT NULL,
    PERIOD   CHAR(1) NOT NULL,
    VAL      BIGINT NOT NULL,
    DT       TIMESTAMP NOT NULL,
    UNITS    CHAR(1) NOT NULL
);

过程ddl片段：

CREATE OR ALTER PROCEDURE ADD_SUMMARY (
    ip varchar(20),
    if_key varchar(20),
    if_num integer,
    val bigint,
    dt timestamp)
as...

我写了一个小测试：测试代码

tx, err := db.Begin()
if err != nil {
    tx.Rollback()
}
_, err = tx.Exec("insert into test(B1) values(?)", uint64(2147483648))
if err != nil {
    fmt.Println(err)
}
tx.Commit()

试验台ddl：

CREATE TABLE TEST (
    B1  BIGINT
);

结果：b1=-2147483648
