如何将cmd中的命令输出到文本区域

Question

I am using Java and using Scanner class. I'll take an SQL query as input and store it into String s .

Scanner sc=new Scanner(System.in);
String s=sc.nextLine();

I want to execute this string (query) and display the result obtained in SQL command line in a text area in swings.

For example if the input is

update emp set no=526 where id='abc'

then the text area should display:

1 row(s) updated

and similarly whatever is displayed in the SQL command line for any query.

BASICALLY OUTPUT OF COMMAND LINE SHOULD BE REDIRECTED TO TEXT AREA

Answer 1

If you are using JDBC to access the DB, you could do something like this:

// Create the UPDATE statement
PreparedStatement pstmt = con.prepareStatement("update emp set no=? where id=?");
pstmt.setLong(1, 526L);
pstmt.setString(2, "abc");

// Execute it
int rowCount = pstmt.executeUpdate();
// You receive as result the count of modified rows
...
// And then update the textArea
textArea.setText(String.format("%d row(s) updated", rowCount));
