Why i am getting this error com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column in 'sdate' 'field list'

I am making a small inventory management project using Java swing, JDBC and a MySQL database in my project. I have three buttons, "Purchase", "Sale" and "Clear". If I click the purchase button then it updates my "product, purchase" table by adding the product name, price, quantity etc. The purchase button is working properly but the sale button is not working.

This is my project view:

enter image description here

When I click my Sale button it gives me this Exception:

How can I solve this problem?

You have a type are using sdate but you have pdate - ScaisEdge
@scaisEdge that sale table has an sdate. - Mark Rotteveel
You need to reduce the amount of code and only show the minimum required to reproduce this error (including the stored procedure DDL). As far as I can tell one of your stored procedures (save_sale) references a column sdate on a table that doesn't have a column with that name. - Mark Rotteveel
I have posted an asnwer hope is useful - ScaisEdge
Please post the DDL as code, not as an image. The problem BTW is that your purchase table doesn't have a column sdate, so you need to fix that stored procedure to use pdate. - Mark Rotteveel

Somewhere you have Sdate and pdate .. so .. sdate and Sdate are not the same and check also for pdate 

    try {
        myConn = DatabaseConnectionHelper.getConnection();
        myCsmt = (CallableStatement) myConn.prepareCall("{ CALL save_sale(getProductid(?), ?, ?, ?) }");

        myCsmt.setString(1, pname);
        myCsmt.setString(2, price);
        myCsmt.setString(3, Sdate); /// this one  
        myCsmt.setString(4, qty);

Looking to your image .. you are try to insert in purchase using sdate .. but in purchase the column is named pdate ..
