我有下表：

CREATE TABLE Users (
  user_id BIGSERIAL PRIMARY KEY,
  email VARCHAR(50) NOT NULL,
  password_hash VARCHAR(100) NOT NULL,
  points INT DEFAULT 0,
  created_at TIMESTAMP NOT NULL DEFAULT NOW(),
  updated_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
)

我输入电子邮件和密码，加密密码并尝试将它们插入表中：

import (
  _ "github.com/lib/pq"
  "database/sql"
  "code.google.com/p/go.crypto/bcrypt"
)

conn := OpenConnection()
defer conn.Close()
email := r.FormValue("email")
password, _ := bcrypt.GenerateFromPassword([]byte(r.FormValue("password")), bcrypt.DefaultCost)
res, err := conn.Exec("INSERT INTO users (email, password_hash) VALUES (?, ?)", email, password)
http.Redirect(w, r, "/", http.StatusFound)

插入物抛出pq: P:"51" S:"ERROR" L:"1002" C:"42601" M:"syntax error at or near \",\"" F:"scan.l" R:"scanner_yyerror"。如果我用简单的字符串替换字节类型密码，则会引发相同的错误。

我究竟做错了什么？

如果链接消失，我将作为答案发布：来自https://github.com/lib/pq/issues/65

作者： dpapathanasiou：我已经解决了问题；这不是 pq 中的错误，而是我创建准备好的语句的方式：我需要使用 ($n) 而不是 ? 对于绑定参数。

所以所有这些语句都可以正常工作：

stmt, err := db.Prepare("select id from people where firstname = ($1) and lastname = ($2)")
stmt, err := db.Prepare("select id from people where firstname ~* ($1) and lastname ~* ($2)")
stmt, err := db.Prepare("select id from people where firstname = ($1)")
