无法在 SQLite 上的命令行上访问表

Cannot access tables on command line on SQLite

我在 c：\tmp 中使用以下代码在 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，出现"没有这样的表"错误。

以下是我如何在C++中创建数据库

    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: %sn", sqlite3_errmsg(db));
       return(0);
    }else{
       printf(  "Opened database successfullyn");
    }
    /* 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: %sn", zErrMsg);
       sqlite3_free(zErrMsg);
  }else{
      printf(  "Table created successfullyn");
 }
 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: %sn", zErrMsg);
      sqlite3_free(zErrMsg);
  }else{
      printf(  "Records created successfullyn");
  }

然后，当我通过命令行访问LoadDates时，出现以下错误。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

在命令行上调用sqlite3.exe时使用完整的文件名：

C:temp> sqlite3.exe myTest1.db
