Question

String sql= "select amount,\n"+ "Temperature,\n"+ "Density\n"+
    "from sheet\n"+ "where Code=? and product=? and and month(date)=? && year(date)=? ";

PreparedStatement stmt=DBConnectionDATABASE.prepareStatement(sql);

try {
    stmt.setString(1, get.Code());
    stmt.setString(2, get.Product());
    stmt.setInt(3, get.month());
    stmt.setInt(4, get.Year());

how can i find the last day of previous month with data .

Answer 1

use this query

select max(date) from sheet where date between ? and ? 

this will return the maximum date between the date range

then

select * from sheet where date=(select max(date) from sheet where date between ? and ?);

I am well aware that its not ethical to use aggregate functions without group by but it works in this case.
