To create new records, use INSERT statements.

INSERT Syntax

The INSERT statement specifies the columns to be inserted and the new column values. You can specify the column values in a comma-separated list in the VALUES clause, as shown in the following example:

INSERT INTO <table_name> 
( <column_reference> [ , ... ] )
VALUES 
( { <expression> | NULL } [ , ... ] ) 
  

<expression> ::=
  | @ <parameter> 
  | ?
  | <literal>

You can use the executeUpdate method of the Statement and PreparedStatement classes to execute data manipulation commands and retrieve the rows affected.

String cmd = "INSERT INTO [CData].[Entities].Customers (CompanyName) VALUES (?)";
PreparedStatement pstmt = connection.prepareStatement(cmd);
pstmt.setString(1, "Caterpillar");
int count = pstmt.executeUpdate();
System.out.println(count+" rows were affected");
connection.close();
