Question

我使用c：\ tmp中的以下代码在C ++中创建了数据库。还创建了表，可以在C ++中访问表。但是当我尝试通过SQLite命令行访问该表时，我得到了＃34;没有这样的表＆＃34;错误。

以下是我在C ++中创建数据库的方法

    rc = sqlite3_open_v2("file:///C:/tmp/myTest1.db", &db,  SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE| SQLITE_OPEN_URI, NULL );
    if( rc ){
       printf(  "Can't open database: %s\n", sqlite3_errmsg(db));
       return(0);
    }else{
       printf(  "Opened database successfully\n");
    }

    /* Create SQL statement */
   sql = "CREATE TABLE LoadDates("  \
     "ID           TEXT    NOT NULL," \
     "DT            INT     NOT NULL  );";

   /* Execute SQL statement */
   rc = sqlite3_exec(db, sql, callback, 0, &zErrMsg);
   if( rc != SQLITE_OK ){
       printf(  "SQL error: %s\n", zErrMsg);
       sqlite3_free(zErrMsg);
  }else{
      printf(  "Table created successfully\n");
 }

 sql = "INSERT INTO LoadDates (ID,DT) "  \
     "VALUES ('A1', 20160701 ); " \
     "INSERT INTO LoadDates (ID,DT) "  \
     "VALUES ('A2', 20160601 ); " \
     "INSERT INTO  LoadDates (ID,DT) "  \
     "VALUES ('A3', 20160801  );";

   /* Execute SQL statement */
  rc = sqlite3_exec(db, sql, callback, 0, &zErrMsg);
  if( rc != SQLITE_OK ){
      printf( "SQL error: %s\n", zErrMsg);
      sqlite3_free(zErrMsg);
  }else{
      printf(  "Records created successfully\n");
  }

然后当我通过命令行访问LoadDates时，我得到以下错误。我可以在c：\ tmp目录中看到myTest1.db

c:\tmp>sqlite3.exe myTest1
SQLite version 3.13.0 2016-05-18 10:57:30
Enter ".help" for usage hints.
sqlite> select * from LoadDates;
Error: no such table: LoadDates

Answer 1

在命令行上调用sqlite3.exe时使用完整文件名：

C:\temp> sqlite3.exe myTest1.db

无法在SQLite上的命令行上访问表
