INNER JOIN not working form in Sqlite android

we have two table (toRouteCSV7,UpdateFOCQtyTable).toRouteCSV7 have two columns. ItemNumber and FOCQty and UpdateFOCQtyTable have two columns ItemID,updatefocvalue

toRouteCSV7 
in 
ItemNumber  FOCQty 
A123           0
A124           0
A125           0
A126           0 

UpdateFOCQtyTable

ItemID    updatefocvalue
A125         1256
A126         14596

After Update We need look like this

 ItemNumber  FOCQty 
    A123           0
    A124           0
    A125           1256
    A126           14596

We tried like this

 tx.executeSql('REPLACE INTO toRouteCSV7 (ItemNumber,FOCQty) select dest.ItemNumber,dest.FOCQty,src.ItemID,src.updatefocvalue from UpdateFOCQtyTable src inner join  toRouteCSV7 dest on src.ItemID = dest.ItemNumber');
