Question

我在Postgres命令中是全新的。

我有以下DB2命令来创建表和表空间：

const james = {
    name: 'James',
    height: `5'10"`,
    weight: 185
};

james[Symbol.iterator] = function (){
  const keys = Object.keys(this)
  return {
    next: () => {
      let key = keys.shift();
      return {value: this[key], key, done:keys.length===0};
    }
  }
}

let iterator = james[Symbol.iterator]();
console.log(iterator.next().value); // 'James'
console.log(iterator.next().value); // `5'10`
console.log(iterator.next().value); // 185

现在我想在postgresql中运行这些命令，我试过

CREATE USER TEMPORARY TABLESPACE MYSPACE MANAGED BY AUTOMATIC STORAGE#

CREATE TABLESPACE SYSTOOLSPACE MANAGED BY AUTOMATIC STORAGE#

CREATE SEQUENCE REVISION AS BIGINT START WITH 1 INCREMENT BY 1 MAXVALUE 4611686018427387903 CYCLE CACHE 1000#

我也有这个DB2 my_db=# CREATE USER TEMPORARY TABLESPACE MYSPACE MANAGED BY AUTOMATIC STORAGE; ERROR: syntax error at or near "TABLESPACE" LINE 1: CREATE USER TEMPORARY TABLESPACE MYSPACE MANAGED BY AUTO... my_db=# CREATE TABLESPACE SYSTOOLSPACE MANAGED BY AUTOMATIC STORAGE; ERROR: syntax error at or near "MANAGED" LINE 1: CREATE TABLESPACE SYSTOOLSPACE MANAGED BY AUTOMATIC STORAGE;语句：

CREATE TABLE

我试图将其转换为Postgres：

CREATE TABLE USER (
  ID BIGINT GENERATED BY DEFAULT AS IDENTITY (START WITH 1 INCREMENT BY 1 NO MAXVALUE NO CYCLE CACHE 100),
  E_VER BIGINT NOT NULL,
  NAME VARCHAR(38) NOT NULL UNIQUE,
  EMAIL_ADDRESS VARCHAR(255) NOT NULL,
  PASSWORD VARCHAR(32) NOT NULL,
  SUPER_ADMIN SMALLINT NOT NULL,
  MAIN_ADMIN SMALLINT NOT NULL,
  SERVER_ADMIN SMALLINT NOT NULL,
  GROUP_ADMIN SMALLINT NOT NULL,
  CLIENT_ADMIN SMALLINT NOT NULL,
  ENABLED SMALLINT NOT NULL,
  HIDDEN SMALLINT NOT NULL,
  PRIMARY KEY (ID)
)#

来自http://www.sqlines.com/online这个在线网站。运行此命令后，我收到错误

CREATE SEQUENCE USER_seq START WITH 1 INCREMENT BY 1;

CREATE TABLE USER (
  ID BIGINT DEFAULT NEXTVAL ('USER_seq'),
  E_VER BIGINT NOT NULL,
  NAME VARCHAR(38) NOT NULL UNIQUE,
  EMAIL_ADDRESS VARCHAR(255) NOT NULL,
  PASSWORD VARCHAR(32) NOT NULL,
  SUPER_ADMIN SMALLINT NOT NULL,
  MAIN_ADMIN SMALLINT NOT NULL,
  SERVER_ADMIN SMALLINT NOT NULL,
  GROUP_ADMIN SMALLINT NOT NULL,
  CLIENT_ADMIN SMALLINT NOT NULL,
  ENABLED SMALLINT NOT NULL,
  HIDDEN SMALLINT NOT NULL,
  PRIMARY KEY (ID)
)#

这次转换有什么不对吗？有什么建议可以解决这个错误吗？

Answer 1

USER是保留字，您需要将其作为CREATE TABLE "USER"转义。

对于您的CREATE USER和CREATE TABLESPACE命令，这只是错误的语法。例如，Postgres中没有MANAGED BY。

在Postgresql TABLESPACE和CREATE命令上获取错误
