【问题描述】：

任何人都可以解释为什么我在 postgis 中遇到此错误，第一次使用。

试图创建一个仓库的表，只是在里面扔了一些随机字符。

完整的错误代码是：

错误：“Warehouse_id”或附近的语法错误第 3 行：Warehouse_id VARCHAR(100), ^ SQL 状态：42601 字符：58

这是我的数据：

CREATE TABLE Warehouse (
Warehouse_location  VARCHAR(25)
Warehouse_id  VARCHAR(100),
Warehouse_managers  VARCHAR(25)
Warehouse_address  VARCHAR(25)
Warehouse_capacity  VARCHAR(50),
Warehouse_occupied  VARCHAR(50),
Warehouse_loading bays VARCHAR(50),
Warehouse_accesspoints VARCHAR(50),
);
INSERT INTO Warehouse Values('Vic','1235','John', '12 Sidney St','500','230','10','5');
INSERT INTO Warehouse Values('Vic','1236','Drake', '156 Can Rd','400','250','10','6');
INSERT INTO Warehouse Values('Nsw','1237','Dave', '120 Toast Ave','400','240','9','5');
INSERT INTO Warehouse Values('Vic','1238','Daniel', '99 Foot St','550','255','10','5');
INSERT INTO Warehouse Values('Nsw','1434','Chirs', '21 Jump St','500','270','9','6');
INSERT INTO Warehouse Values('Nsw','1734','Liam', '1 Bishop St','500','150','6','5');
INSERT INTO Warehouse Values('Vic','7234','Steve', '12 Bewick Grove ','440','250','3','5');
INSERT INTO Warehouse Values('Vic','8234','Bob', '23 Rannoch Wood Rd','440','250','11','5');
INSERT INTO Warehouse Values('Vic','1224','Kim', '390 Park Ave','550','250','9','6');
INSERT INTO Warehouse Values('SA','4234','Alex', '2 Grange Dr','550','250','10','5');
INSERT INTO Warehouse Values('SA','1734','Ryan', '12 Food St','500','350','10','5');

【问题讨论】：

你少了一个逗号？
确实如此。只是在第 2 行末尾缺少一个逗号，在 VARCHAR(25) 和 Warehouse_id 之间
好的，谢谢知道一些简单的遗漏
现在只是吐出 ERROR: syntax error at or near ")" LINE 10: ); ^ 在括号里？

【解决方案1】：

您缺少几个逗号，并且有一个带有空格的列名。要么用双引号 " 包裹它，要么去掉它，例如使用_（恕我直言更优雅）：

CREATE TABLE Warehouse 
( Warehouse_location VARCHAR(25), 
  Warehouse_id VARCHAR(100), 
  Warehouse_managers VARCHAR(25), 
  Warehouse_address VARCHAR(25),
  Warehouse_capacity VARCHAR(50), 
  Warehouse_occupied VARCHAR(50), 
  "Warehouse_loading bays" VARCHAR(50), -- consider using Warehouse_loading_bays instead
  Warehouse_accesspoints VARCHAR(50)
); 

 INSERT INTO Warehouse Values('Vic','1235','John', '12 Sidney St','500','230','10','5'); 
 INSERT INTO Warehouse Values('Vic','1236','Drake', '156 Can Rd','400','250','10','6'); 
 INSERT INTO Warehouse Values('Nsw','1237','Dave', '120 Toast Ave','400','240','9','5'); 
 INSERT INTO Warehouse Values('Vic','1238','Daniel', '99 Foot St','550','255','10','5'); 
 INSERT INTO Warehouse Values('Nsw','1434','Chirs', '21 Jump St','500','270','9','6'); 
 INSERT INTO Warehouse Values('Nsw','1734','Liam', '1 Bishop St','500','150','6','5'); 
 INSERT INTO Warehouse Values('Vic','7234','Steve', '12 Bewick Grove ','440','250','3','5'); 
 INSERT INTO Warehouse Values('Vic','8234','Bob', '23 Rannoch Wood Rd','440','250','11','5'); 
 INSERT INTO Warehouse Values('Vic','1224','Kim', '390 Park Ave','550','250','9','6'); 
 INSERT INTO Warehouse Values('SA','4234','Alex', '2 Grange Dr','550','250','10','5'); 
 INSERT INTO Warehouse Values('SA','1734','Ryan', '12 Food St','500','350','10','5');
