我想在gridview中交换位置并在android上获取语法错误。
android.database.sqlite.SQLiteException：near＆＃34; a＆＃34 ;:语法错误（代码1）：
public void swapNewspaperSeialByPosition(int oldPosition, int newPosition) {
String selectQuery2 = "UPDATE " + TBL_NEWSPAPER + " a INNER JOIN " + TBL_NEWSPAPER
+ " b ON a.rowid <> b.rowid SET a.serialNo = b.serialNo WHERE a.rowid IN ("
+ oldPosition + "," + newPosition + ") AND b.rowid IN ("
+ newPosition + "," + oldPosition + ")";
SQLiteDatabase db = this.getWritableDatabase();
db.execSQL(selectQuery2);
}
这里的logcat：
