다음 코드는 db에 새 테이블을 만듭니다. 나는 그것이 모든 SQL 오류를 잡아서 테이블이 이미 존재한다면 계속해서 실행하고 싶습니다. 그러나 코드를 실행할 때 테이블이 이미 있으면 예상대로 예외가 발생하지만 컴파일 중에 코드가 종료됩니다. try catch가 무시되고 있습니까?캐치를 무시 하시겠습니까?
코드 :
(ns app.storage
(:import com.mchange.v2.c3p0.ComboPooledDataSource
(clojure.lang ExceptionInfo))
(:require [clojure.java.jdbc :refer :all]))
(def db {
:classname "org.sqlite.JDBC"
:subprotocol "sqlite"
:subname "src/storage/journal.db"
})
(defn create-db []
(try
(db-do-commands db
(create-table-ddl :entry
[:id :primary :key]
[:account "varchar(255)"]
[:timestamp "timestamp"]
[:debt "double(9,2)"]
[:credit "double(9,2)"]))
(catch ExceptionInfo e
(println e))))
(create-db)
예외 :
Exception in thread "main" java.sql.BatchUpdateException: batch entry 0: [SQLITE_ERROR] SQL error or missing database (table entry already exists), compiling:(app/storage.clj:29:21)
