Question

我收到如下所示的错误消息，当我创建此表时，就像其他人设置列时间戳timestamp without time zone NOT NULL一样，但当我尝试将2015-08-16 18:51:05插入此表时，我得到错误，但是其他表是工作，为什么以及如何解决它？

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);
      }
    });
  });
};

对我来说，强制转换类型显然有效。请注意，我使用了joda Datetime

@CreatedDate
@Column(name = "created_on", updatable = false, nullable = false)
@Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
private DateTime createdOn;

column的类型为timestamp，没有时区，但expression的类型为integer
