列是不带时区的时间戳types，但expression式的types是整数

我得到像下面的错误信息，当我创build这个表就像其他人设置列时间戳timestamp without time zone NOT NULL ，但是当我试图插入2015-08-16 18:51:05到这张表，然后我得到错误，但其他表是工作，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

 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

这是因为您正在将整数数据插入time stamp列。

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select2为TokenTimestamp ，这就是为什么你得到这个错误。

你应该用一些date时间格式replace2 yyyy-mm-dd hh:mm:ss 。

例如： '2015-08-07 05:00:01'
