在我的Android APP中，我试图从一个表中获取详细信息，然后将这些记录插入到另一个表中并加入另一个表。
SQLLITE插入语句连续多次失败。我已经尝试了很多东西来解决INSERT语句中的问题，但我没有成功。
我已经附加了日志，SQL表声明和我面临问题的INSERT语句。你能帮我解决一下这个问题。
sql = "INSERT INTO " + DATABASE_TABLE_TRAN + " (" +
KEY_ID + "," +
KEY_NAME + "," +
KEY_COIN + "," +
KEY_DATE + "," +
KEY_TYPE + "," +
KEY_QTY + "," +
KEY_PRICE + "," +
KEY_PRICE_UNIT +
") " +
" VALUES (" +
" SELECT " +
"TRN." +KEY_ID + "," +
"ALT." +KEY_NAME + "," +
"TRN." +KEY_COIN + "," +
"TRN." +KEY_DATE + "," +
"TRN." +KEY_TYPE + "," +
"TRN." +KEY_QTY + "," +
"TRN." +KEY_PRICE + "," +
"TRN." +KEY_PRICE_UNIT +
" FROM " + DATABASE_TABLE_TRAN_TEMP + " TRN, " +
DATABASE_TABLE_ALTCOIN + " ALT " +
" WHERE " + "TRN."+KEY_COIN + " = " + "ALT."+KEY_COIN +
" )";
Log.i("Insert Query",sql);
db.execSQL(sql);
logcat的

答案 0 :(得分：3)
使用VALUES语句时，不能有insert into ... select ...个关键字。
删除
" VALUES (" +
和
" )";
来自你的代码。
应该是：
sql = "INSERT INTO " + DATABASE_TABLE_TRAN + " (" +
KEY_ID + "," +
KEY_NAME + "," +
KEY_COIN + "," +
KEY_DATE + "," +
KEY_TYPE + "," +
KEY_QTY + "," +
KEY_PRICE + "," +
KEY_PRICE_UNIT +
") " +
" SELECT " +
"TRN." +KEY_ID + "," +
"ALT." +KEY_NAME + "," +
"TRN." +KEY_COIN + "," +
"TRN." +KEY_DATE + "," +
"TRN." +KEY_TYPE + "," +
"TRN." +KEY_QTY + "," +
"TRN." +KEY_PRICE + "," +
"TRN." +KEY_PRICE_UNIT +
" FROM " + DATABASE_TABLE_TRAN_TEMP + " TRN, " +
DATABASE_TABLE_ALTCOIN + " ALT " +
" WHERE " + "TRN."+KEY_COIN + " = " + "ALT." + KEY_COIN;
