列是没有时区的时间戳类型，但表达式是整数类型

Question

我收到如下错误消息，当我像创建其他表一样设置该表时timestamp without time zone NOT NULL，却设置了列时间戳，但是当我尝试插入2015-08-16 18:51:05该表时，我得到了错误，但是其他表却在工作，为什么以及如何解决呢？

CREATE TABLE IF NOT EXISTS "UserForgetPasswordPending"(
"UserForgetPasswordPendingId" SERIAL NOT NULL,
"Email" varchar(50) NOT NULL,
"TokenTimestamp" timestamp without time zone NOT NULL,
"Token" varchar(100) NOT NULL,
PRIMARY KEY ("UserForgetPasswordPendingId")
);
ALTER TABLE "UserForgetPasswordPending"
  OWNER TO db_admin;

错误

[error: column "TokenTimestamp" is of type timestamp without time zone but expression is of type integer]
  name: 'error',
  length: 216,
  severity: 'ERROR',
  code: '42804',
  detail: undefined,
  hint: 'You will need to rewrite or cast the expression.',

插入

var utc = moment(new Date()).unix();
var tokenTimestamp = moment.unix(utc).format('YYYY-MM-DD HH:mm:ss');

var upsertUserForgetPasswordPending = function(userEmail, tokenTimestamp, token) {
  return new Promise(function (fulfill, reject){
    var queryInsert = 'INSERT INTO "UserForgetPasswordPending" ("Email","TokenTimestamp","Token") SELECT $1,2,$3';
    var queryUpsert = 'UPDATE "UserForgetPasswordPending" SET "TokenTimestamp" = $2, "Token" = $3 WHERE "Email" = $1';
    var query = 'WITH upsert AS ('+queryUpsert+' RETURNING *) '+queryInsert+' WHERE NOT EXISTS (SELECT * FROM upsert)';
console.log(tokenTimestamp);
    dbClient.query(query, [userEmail,tokenTimestamp,token], function(error, result) {
      if (error) {
        reject(error);
      } else {
        fulfill(result);
      }
    });
  });
};

Answer 1

这是因为您要将整数数据插入到time stamp列中。

更正以下语法：

var queryInsert = 'INSERT INTO "UserForgetPasswordPending ("Email","TokenTimestamp","Token") SELECT $1,2,$3';

在上面的查询中，您选择的2是TokenTimestamp这就是为什么导致此错误。

您应该2用某种日期时间格式替换yyyy-mm-dd hh:mm:ss。

例如： '2015-08-07 05:00:01'
