Question

I have a field name varaince in a table set to type Number(20,3) in oracle…..
I get number as string from the webpage and convert it to Double so I can write it back to table as shown below

if ( (this.getVariance() != null) && (this.getVariance().length() > 0) )
                cstmt.setDouble(7,Util.stringToDouble(this.getVariance()));
            else
                cstmt.setNull(7,OracleTypes.NUMBER);

but i am getting this error

compile:
     [exec] com\sample\common\javabean\ExampleBean.java:261: cannot resolve symbol
     [exec] symbol  : method setDouble (int,java.lang.Double)
     [exec] location: interface java.sql.CallableStatement
     [exec]                             cstmt.setDouble(7,Util.stringToDouble(this.getVariance()));
     [exec]           

                       ^

when i was doing samething as integer it didnt give me error but it didnt write to table.

What can be done to convert string in such a way that table will write that number from the form. Any help would be good

Answer 1

Do you really need to convert it to a double? You could do this:

cstmt.setBigDecimal(7, new java.math.BigDecimal(this.getVariance()));
