구문 오류는 상수 문자열을 분할 할 경우이 라인

const char *sql_stmt = [@"create table if not exists studentsDetail (regno integer primary key, name text, department text, year text)" UTF8String]; 

Answer 1

에서 온 여러 소스 라인에 넣으려면 각 부분을으로 묶어야합니다. tation 마크 :

const char *sql_stmt = 
"create table if not exists studentsDetail (regno integer " 
"primary key, name text, department text, year text)"; 

대신은 :

const char *sql_stmt = 
"create table if not exists studentsDetail (regno integer 
primary key, name text, department text, year text)"; 

Answer 2

로 코드를 교체하십시오

const char *sql_stmt = "create table if not exists studentsDetail (regno integer 
         primary key, name text, department text, year text)";
