适用于Android的SQLite小写

我现在遇到如何在sqlite for Android中将大写单词转换为小写的问题.

public Cursor fetchFunctions(String searchword) throws sqlException {
    Cursor mCursor =
        mDb.query(true, FUNCTIONS_TABLE, new String[] {
                FUNS_WORD, FUNS_BODY}, FUNS_WORD + "='" + searchword + "'", null,
                null, null, null, null);
    if (mCursor != null) {
        mCursor.movetoFirst();
    }
    return mCursor;
}

我想转发像LOWER(FUNS_WORD)“=’”searchword“’”,遗憾的是,语法错误.我想要的是我想将FUNS_WORD中的所有数据转换为小写类型.

解决方法:

你必须使用rawQuery

public Cursor fetchFunctions(String searchword) throws sqlException {
    Cursor mCursor =
        mDb.rawQuery("SELECT FUNS_WORD, FUNS_BODY FROM FUNCTIONS_TABLE WHERE LOWER(FUNS_WORD) = '" + searchword + "'", null);
    if (mCursor != null) {
        mCursor.movetoFirst();
    }
    return mCursor;
}
