Question

我正在尝试使用3个值更新数据库中的行，但我一直收到语法错误，我不知道为什么，一切看起来都不错。

这是我更新的地方

    public void addToTeam(View v){
    TextView tv = (TextView)findViewById(R.id.bowlersNameTV);
    EditText et = (EditText)findViewById(R.id.posET);
    CheckBox cb = (CheckBox)findViewById(R.id.checkBox1);
    int pos =  Integer.valueOf(et.getText().toString());
    int sub = 0;
    if(cb.isSelected())
        sub = 1;
    ContentValues val = new ContentValues();
    val.put(BowlersDB.TEAM,teamEdited);
    val.put(BowlersDB.POSITION,pos);
    val.put(BowlersDB.SUB,sub);
    getContentResolver().update(BowlersDB.CONTENT_URI,val,BowlersDB.NAME + "=" + tv.getText().toString(),null);
}

这是我的内容提供商更新

@Override
public int update(Uri uri, ContentValues values, String selection,
        String[] selectionArgs) {
    int count = 0;
    int num = uriMatcher.match(uri);
    if(num == 1){
        count = db.update(BOWLERS_TABLE, values, selection, selectionArgs);
    }else if(num == 2){
        count = db.update(BOWLERS_TABLE, values, ID + " = " + uri.getPathSegments().get(1) + (!TextUtils.isEmpty(selection) ? " AND (" + 
                  selection + ')' : ""), 
                  selectionArgs);
    }else{
        throw new IllegalArgumentException(
                "Unknown URI " + uri);
    }
    getContext().getContentResolver().notifyChange(uri, null);
    return count;
}

我的语法在哪里错了？错误告诉我它接近姓氏的末尾，但就是这样

Answer 1

:) 引起：android.database.sqlite.SQLiteException：靠近“Smith”：语法错误：，同时编译：UPDATE bowlers_table SET team_pos = ?, substitute = ?, team =？姓名= Joe Smith

你应该用引号括起Joe Smith。在这一行 getContentResolver（）。update（BowlersDB.CONTENT_URI，val，BowlersDB.NAME +“=”+ tv.getText（）。toString（），null）;

尝试更新行时SQLite语法错误
