Question

我希望有人可以帮助我，

所以我正在使用clojure和postgresql构建数据库支持的网站，但我一直在收到错误。以下是REPL的代码和错误：

(ns app.config-postgre
  (require [clojure.java.jdbc :as sql]))

(def db1
  {:classname "org.postgresql.Driver"
   :subprotocol "postgresql"
   :subname "//localhost:5432/dbname"
   :username "username"
   :password "password}) 
;;that's not the real username and password, the real one is right

这里是导致错误的代码：

(sql/insert! db1 :user123
             {:username "user" :password "pass" :user-id "1"})
;;PSQLException ERROR: syntax error at or near "user"
  Position: 43  org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse (QueryExecutorImpl.java:2157)

和

(sql/execute! db1 ["INSERT INTO user123 VALUES ('{\"user\", \"pass\" ,1}')"])
;;PSQLException ERROR: null value in column "password" violates not-null constraint
  Detail: Failing row contains ({user,pass,1}, null, null).  org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse (QueryExecutorImpl.java:2157)

和

(sql/execute! db1 ["INSERT INTO user123 VALUES ('{\"user\"},{\"pass\"},{1}')"])
;;PSQLException ERROR: malformed array literal: "{"user"},{"pass"},{1}"
  Detail: Junk after closing right brace.
  Position: 29  org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse (QueryExecutorImpl.java:2157)

和

(sql/execute! db1 ["INSERT INTO user123 VALUES ('\"user\",\"pass\",1')"])
;;PSQLException ERROR: malformed array literal: ""user","pass",1"
  Detail: Array value must start with "{" or dimension information.
  Position: 29  org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse (QueryExecutorImpl.java:2157)

和

(sql/execute! db1 ["INSERT INTO user123 VALUES ('user','pass',1)"])
;;PSQLException ERROR: malformed array literal: "user"
  Detail: Array value must start with "{" or dimension information.
  Position: 29  org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse (QueryExecutorImpl.java:2157)

有什么建议吗？提前谢谢

编辑表user123的模式：

CREATE TABLE user123
(
  username character varying(100)[] NOT NULL,
  password character varying(100)[] NOT NULL,
  "user-id" integer NOT NULL,
  CONSTRAINT user_pkey PRIMARY KEY ("user-id")
)

Answer 1

将(sql/execute! db1 ["INSERT INTO user123 VALUES (?, ?, ?)" "user" "pass" 1])用于您的目的

Answer 2

(sql/execute! db1 ["INSERT INTO user123 VALUES ({'user'}, {'pass'}, 1);"])

Answer 3

我认为您应该在数据库规范中将：用户名更改为：用户。
