org.postgresql.util.PSQLException: ERROR: column "dsa" does not exist - postgresql

Question

I am trying to develop a java web app. It is connected to a postgresql database. In this database, I have a table called emp99.In it there is a column called company. when I try to add values to the table I get an error which is:
org.springframework.jdbc.BadSqlGrammarException: StatementCallback; bad SQL grammar [insert into emp99(name,salary,designation,age,surname,department,company,address,working) values('s',1.0,'d',4,'ff',gg,'dd',true )]; nested exception is org.postgresql.util.PSQLException: ERROR: column "gg" does not exist
But I have this column
CREATE TABLE emp99 (
id int PRIMARY KEY,
name VARCHAR ( 50 ) ,
salary float ,
designation varchar(50),
age int,
surname varchar(50),
department varchar(50),
company varchar(50),
address varchar(50),
working Boolean
);
and this is my adding code:
public int save(Emp p){
String sql="insert into emp99(name,salary,designation,age,surname,department,company,address,working) values('"+p.getName()+"',"+p.getSalary()+",'"+p.getDesignation()+"',"+p.getAge()+",'"+p.getSurname()+"',"+p.getCompany()+",'"+p.getAddress()+"',"+p.getWorking()+" )";
return template.update(sql);
}

#stiky bit you were right i was missing Quotes. The correct one:
public int save(Employee p){
String sql="insert into emp89(name,salary,surname,departmentname,company,address,working,age,saat) values('"+p.getName()+"','"+p.getSalary()+"','"+p.getSurname()+"','"+p.getDepartmentname()+"','"+p.getCompany()+"','"+p.getAddress()+"','"+p.getWorking()+"','"+p.getAge()+"','"+saat+"')";
return template.update(sql);
