SQLite查询报出异常

在数据库中执行一个查询的时候报出异常:

bind or column index out of range

ContentProvider中的查询如下:

@Override
public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) {
    SQLiteQueryBuilder queryBuilder = new SQLiteQueryBuilder();
    int uriType = sURIMatcher.match(uri);
    switch (uriType) {
    case RESPONSEVIEW2_SELECTION_10:
        queryBuilder.setTables(RESPONSES_VIEW);
        String activeUserKey = getActiveUserId();;
        String outerSelection = 
                "(((" + PeerCreatedDataColumns.SHARED + "=" + "" + trueId + "" + ") OR " 
                + "(" + PeerCreatedDataColumns.AUTHORHASH + "=" + "'" + activeUserKey + "'" + ")) AND (" 
                + "(" + ResponsesColumns.PRIMARYMATCH + "= '*'" + ") OR " 
                                    // '*'是程序定义的 , 希望不会和别的有冲突
                + "(" + ResponsesColumns.PRIMARYMATCH + " like '?') OR " 
                + "(" + ResponsesColumns.PRIMARYMATCH + " like '" + selectionArgs[0] + "%') OR " 
                + "(" + ResponsesColumns.PRIMARYMATCH + " like '%" + selectionArgs[0] + "') OR " 
                + "(" + ResponsesColumns.PRIMARYMATCH + " like '%" + selectionArgs[0] + "%'" + ")))";
        Log.d(DEBUG_TAG, "query " + outerSelection);
        Cursor cursor10 = queryBuilder.query(mDB.getReadableDatabase(), projection, outerSelection, selectionArgs,
                null, null, sortOrder);
        cursor10.setNotificationUri(getContext().getContentResolver(), uri);
        Log.e(DEBUG_TAG, "responses_view2 should have better search function");
        return cursor10;
    case ROW_SELECTION_11:
        queryBuilder.setTables(RESPONSES_VIEW);
        Log.e(DEBUG_TAG, "responses_view2 should have better search function");
        queryBuilder.appendWhere(PeerDatabase._ID + "=" + uri.getLastPathSegment());
        Cursor cursor11 = queryBuilder.query(mDB.getReadableDatabase(), projection, selection, selectionArgs, null,
                null, sortOrder);
        cursor11.setNotificationUri(getContext().getContentResolver(), uri);
        return cursor11;
    ...
    }
}

然后cursor loader如下:

public Loader<Cursor> onCreateLoader(int id, Bundle args) {
    if (search == null) {
        return null;
    } else {
        String[] selectArgs = { search };
        return new CursorLoader(getActivity(), table, createProjection, "?", selectArgs, null);
    }
}

报出错误如下:

请帮忙指点一下错误的原因,或者还有更好的查询方法,谢谢。

    不要把?包在括号里:

    " like '?') OR "
    

    换成

    " like ?) OR "
    

    如果搜索是用户输入, 还要防止SQL注入攻击:

    + "(" + ResponsesColumns.PRIMARYMATCH + " like ?) OR " 
    + "(" + ResponsesColumns.PRIMARYMATCH + " like ?) OR " 
    + "(" + ResponsesColumns.PRIMARYMATCH + " like ?) OR " 
    + "(" + ResponsesColumns.PRIMARYMATCH + " like ?)))";
    

    创建一个新的selectionArgs参数:

    String search = selectionArgs[0];
    String[] matchArgs = { search, search + "%", "%" + search, "%" + search + "%" };
    Cursor cursor10 = queryBuilder.query(mDB.getReadableDatabase(), projection, 
                outerSelection, matchArgs, null, null, sortOrder);

    并非你代码出现的问题,而是在cursor.getXXX(columnid)的时候columnid是错误的。
