私は3つのクラスを持っています。 DBとテーブルをセットアップするには、うまく動作します。 DBHelper.javaSQLiteクエリSQLiteLog（1）そのような列：
private static final String TAG = "DBHelper";
public static final String DB_NAME = "pat_test.db";
public static final String TABLE5 = "sites";
public static final String S_ID = BaseColumns._ID;
public static final String S_CLIENT = "client_of_site";
public static final String S_POSTCODE = "site_postode";
public static final String S_CON_NAME = "contact_name";
public static final String S_CON_NUM = "contact_tel_num";
public static final String S_NAME = "site_name";
public static final String S_LAST_TEST = "last_test_date";
public DBHelper(Context context) {
super(context, DB_NAME, null, DB_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
String sql5 = String.format("create table %s (%s INT PRIMARY KEY, %s TEXT, %s TEXT, %s TEXT, %s TEXT, %s INT, %s TEXT)",TABLE5, S_ID, S_CLIENT, S_NAME, S_POSTCODE, S_CON_NAME,S_CON_NUM,S_LAST_TEST);
Log.d(TAG, "onCreate: " + sql5);
db.execSQL(sql5);
}
次はDBControl.java
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteException;
import android.provider.BaseColumns;
public class DBControl {
public static final String TABLE5 = "sites";
public static final String S_ID = BaseColumns._ID;
public static final String S_CLIENT = "client_of_site";
public static final String S_NAME = "site_name";
public static final String S_POSTCODE = "site_postode";
public static final String S_CON_NAME = "contact_name";
public static final String S_CON_NUM = "contact_tel_num";
public static final String S_LAST_TEST = "last_test_date";
private Context context;
private SQLiteDatabase database;
private DBHelper dbhelper;
public DBControl(Context context) {
this.context = context;
}
public DBControl open() throws SQLiteException {
dbhelper = new DBHelper(context);
database = dbhelper.getWritableDatabase();
return this;
}
public void close() {
dbhelper.close();
}
public ContentValues createContentValues3(String CLIENT,
String NAME, String POSTCODE, String CON_NAME,
long CON_NUM) {
ContentValues values = new ContentValues();
values.put(S_CLIENT, CLIENT);
values.put(S_POSTCODE, POSTCODE);
values.put(S_CON_NAME, CON_NAME);
values.put(S_CON_NUM, CON_NUM);
values.put(S_NAME, NAME);
return values;
}
public long addSiteDetails(String CLIENT, String NAME,
String POSTCODE, String CON_NAME, int CON_NUM) {
ContentValues siteValues = createContentValues3(CLIENT, NAME,
POSTCODE, CON_NAME, CON_NUM);
return database.insert(TABLE5, null, siteValues);
}
public boolean updateSiteDetails(long id, String CLIENT, String NAME,
String POSTCODE, String CON_NAME , int CON_NUM
) {
ContentValues siteUpdateValues = createContentValues3(CLIENT, NAME,
POSTCODE, CON_NAME, CON_NUM);
return database.update(TABLE5, siteUpdateValues, S_ID + "=" + id, null) > 0;
}
}
public long fetchSiteIdByName(String NAME){
Cursor dbCursor;
long id = 0;
try {
dbCursor = database.query(true, TABLE5, new String []{S_ID}, S_NAME + "= " + NAME , null, null, null, null, null);
dbCursor.moveToFirst();
id = dbCursor.getLong(dbCursor.getColumnIndex(S_ID)); }
catch (SQLiteException e) {
id = -1;
}
return id;
}
私の第三のクラスを呼び出すと確認するために使用され、私の機能を持っています。しかし、これは私の問題が発生する場所か、前のクラスのfetchSiteIdByNameです。

私がアプリケーションを実行すると、私は新しい詳細を使ってDBに挿入します。 adbを使用するDBをプルし、sqlite3で開きます。最初の列にNULLを、最後にNULLを持つすべてのエントリを表示します（最後はまだ投稿されていません）。 私はeditbox siteDataのフィールドに同じテキストを使用し、新しいエントリを追加するだけで、以前のものは更新しません。
ログcatはSQLiteLog（1）を表示していません。xxxここで、xxxはautocompleteTextViewのエントリです。
入力されたテキストに名前が付けられた列を探しているのはなぜですか？
