How can Query in database table whitout service builder?

[habib zare, modificado 11 Anos atrás.]

There is no entity(there is no service builder) in my portlet but i want to select or insert data in any table of database.

How can i do that?

Hi habib zare ,

You can do this by manual JDBC connection!! but its having lots of disadvantage !!
For Ex:

<%@ page import ="java.sql.*" %>
<%@ page import ="javax.sql.*" %>
<%
	String userid=request.getParameter("user"); 
	session.putValue("userid",userid); 
	String pwd=request.getParameter("pwd"); 
	Class.forName("com.mysql.jdbc.Driver"); 
	java.sql.Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","root"); 
	Statement st= con.createStatement(); 
	ResultSet rs=st.executeQuery("select * from users where user_id='"+userid+"'"); 

	if(rs.next()) 
	{ 
		if(rs.getString(2).equals(pwd)) 
		{ 
			out.println("welcome"+userid); 
		} 
		else 
		{ 
			out.println("Invalid password try again"); 
		} 
	}  
%>

You can just a method in Impl class corresponding to the database table class. If it's a liferay table, you probably won't have problem.

Example
UserLocalServiceImpl.dynamicQuery()

Thanks Hitoshi.

but I added the table in database. table is not liferay table.

And you don't want to use service builder. So did you code dynamicquery and customquery methods yourself? If you did, you can just call that.

[Habib Zare, modificado 11 Anos atrás.]

Yes Hitoshi.

I can call customquery in my finderimpl class when i use servicebuilder like :

 public Object findByName( String name)
		{


		Session session = null;

		
	        session = openSession();

                String sql = CustomSQLUtil.get("com.habib.findByName");

		SQLQuery q = session.createSQLQuery(sql);

		QueryPos qPos = QueryPos.getInstance(q);

		return q.list(true);

               }

but if there is no servicebuilder ,i can`t.

i can`t use openSession().

i want any example to learn.

thx.

That's simply because you didn't create a method. Create it.
How else did you think you can call on a function without generating it or creating it yourself.
