E/SQLiteLog : (1) "ENTER"근처 : 구문 오류

Question

데이터베이스를 만드는 중이 이상한 오류가 발생합니다. 비용 관리자 응용 프로그램을 구축하고 textview에서 SQLite 데이터베이스에 데이터를 저장하려고하지만 저장 단추를 누르면 이러한 오류가 발생합니다. IS 이것은 내가 MainActivity가 아닌 다른 활동으로 데이터베이스를 만들려고하기 때문에 ??

다음은 AddMoney 활동

package com.example.alkesh.expensemanager101; 

import android.content.Context; 
import android.content.Intent; 
import android.database.sqlite.SQLiteDatabase; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.Toast; 

public class AddMoney extends AppCompatActivity implements View.OnClickListener{ 

    Button Save,Cancel; 
    EditText expText; 
    int[] expense=new int[100]; 
    int temp=900; 
    int c=0; 
    int sum=0; 
    String DBOnce; 

    private SQLiteDatabase db; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_add_money); 

     expText=(EditText)findViewById(R.id.expense); 

     Cancel=(Button)findViewById(R.id.cancelbutton); 
     Cancel.setOnClickListener(this); 

     Save = (Button)findViewById(R.id.savebutton); 
     Save.setOnClickListener(this); 

     CreateDatabase(); 
     } 





    @Override 
    public void onClick(View view) { 

     if(view== Save){ 

      insertIntoDatabase(); 

     } 

     if(view==Cancel){ 
      Intent intent =new Intent(AddMoney.this,MainActivity.class); 
      startActivity(intent); 
      finish(); 
     } 

    } 

    protected void CreateDatabase(){ 
     db=openOrCreateDatabase("MoneyDB", Context.MODE_PRIVATE,null); 
     db.execSQL("CREATE TABLE IF NOT EXISTS money(ID INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, name VARCHAR);"); 
    } 



    protected void insertIntoDatabase(){ 
     String amount = expText.getText().toString().trim(); 

     if(amount.equals("")){ 
      Toast.makeText(this,"Please enter your expense or press Cancel to go back",Toast.LENGTH_LONG).show(); 
      return; 
     } 

     String query="ENTER INTO money (name) VALUES ('"+amount+"');"; 
     db.execSQL(query); 
     Toast.makeText(this,"Expense Saved",Toast.LENGTH_LONG).show(); 


    } 

} 

여기 MainActivity에 대한 내 코드의 내 코드입니다. AddMoney 활동 기능 insertIntoDatabase에서

package com.example.alkesh.expensemanager101; 

import android.content.Intent; 
import android.os.Parcelable; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.widget.Button; 
import android.widget.TextView; 
import android.widget.Toast; 

public class MainActivity extends AppCompatActivity { 

    Button Add; 
    TextView expense; 
    int c=0; 
    String DBonce="0"; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 


     Add = (Button) findViewById(R.id.addbutton); 
     Add.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       Intent intent = new Intent(MainActivity.this, AddMoney.class); 
       intent.putExtra("counter", DBonce); 
       startActivity(intent); 
      } 
     }); 

    } 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.menuhome,menu); 
     return super.onCreateOptionsMenu(menu); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     switch(item.getItemId()){ 
      case R.id.feedback:{} 
      break; 

      case R.id.exit: finish(); 
       break; 
     } 
     return super.onOptionsItemSelected(item); 
    } 
}
