Как вы можете проверить, существует ли запись?

Question

Как вы проверяете, существует ли в базе данных запись (ContentValues)?

public void insertData(String ActId,String Dstcode,String Mandicode,String Traderlicno,String licenseId,String licensename,String Gatepassno,String FarmerId,String Farmername,String FarmerFatherName,String CommodityGrpCode,String CommodityCode,String VartyCode,String Cwght,String UntCode,String FnlPrice,String lgndate,String Ip,String dte,String IEMIN0,String ModelNo,String BoardName,String BrandName,String SIMNo) 
    { 

    ContentValues cv = new ContentValues(); 

     cv.put(DatabaseHandler.AUCTIONINFO_ActId, ActId); 
     cv.put(DatabaseHandler.AUCTIONINFO_Dstcode, Dstcode); 
     cv.put(DatabaseHandler.AUCTIONINFO_Mandicode, Mandicode); 
     cv.put(DatabaseHandler.AUCTIONINFO_Traderlicno, Traderlicno); 
     cv.put(DatabaseHandler.AUCTIONINFO_licenseId, licenseId); 
     cv.put(DatabaseHandler.AUCTIONINFO_licensename, licensename); 
     cv.put(DatabaseHandler.AUCTIONINFO_Gatepassno, Gatepassno); 
     cv.put(DatabaseHandler.AUCTIONINFO_FarmerId, FarmerId); 
     cv.put(DatabaseHandler.AUCTIONINFO_Farmername, Farmername); 
     cv.put(DatabaseHandler.AUCTIONINFO_FarmerFatherName, FarmerFatherName); 
     cv.put(DatabaseHandler.AUCTIONINFO_CommodityGrpCode, CommodityGrpCode); 
     cv.put(DatabaseHandler.AUCTIONINFO_CommodityCode, CommodityCode); 
     cv.put(DatabaseHandler.AUCTIONINFO_VartyCode, VartyCode); 
     cv.put(DatabaseHandler.AUCTIONINFO_Cwght, Cwght); 
     cv.put(DatabaseHandler.AUCTIONINFO_UntCode, UntCode); 
     cv.put(DatabaseHandler.AUCTIONINFO_FnlPrice, FnlPrice); 
     cv.put(DatabaseHandler.AUCTIONINFO_lgndate, lgndate); 
     cv.put(DatabaseHandler.AUCTIONINFO_Ip, Ip); 
     cv.put(DatabaseHandler.AUCTIONINFO_dte, dte); 
     cv.put(DatabaseHandler.AUCTIONINFO_IEMIN0, IEMIN0); 
     cv.put(DatabaseHandler.AUCTIONINFO_ModelNo, ModelNo); 
     cv.put(DatabaseHandler.AUCTIONINFO_BoardName, BoardName); 
     cv.put(DatabaseHandler.AUCTIONINFO_BrandName, BrandName); 
     cv.put(DatabaseHandler.AUCTIONINFO_SIMNo, SIMNo); 

      database.insert(DatabaseHandler.TABLE_AUCTIONINFO, null, cv); 

}

Edit:

myDB= openOrCreateDatabase("DBName", MODE_PRIVATE, null); 
myDB.execSQL("CREATE TABLE IF NOT EXISTS MyTable (your query goes here);"); 

Cursor cursor = myDB.rawQuery("select AUCTIONINFO_ActId from TABLE_AUCTIONINFO where AUCTIONINFO_licenseId = licenseId;", null); 
if(cursor.getCount()!=0) 
{ 
    // now you can insert the record 
} 
else 
{ 

}
