删除用户选择的记录？

Question

I am coding

String Name = txtName.getText();
String Surname = txtSurname.getText();  
st.executeUpdate("DELETE from list WHERE Name=@Name and Surname=@Surname");

but it doesn't delete the records. Any problem with the syntax? Please help.

Answer 1

You need to replace @name and @surname with the actual values.

and add ' around your values:

DELETE from list WHERE Name='@Name' and Surname='@Surname'


String Name = txtName.getText().Trim();
String Surname = txtSurname.getText().Trim();  
String query = "DELETE from list WHERE Name='" + Name + "' and Surname='" + Surname + "'";
st.executeUpdate(query);

Answer 2

try:

st.executeNonQuery("DELETE from list WHERE Name=?e and Surname=?");

and pass the name and surname as parameters.

Answer 3

Use this

If the table list exists .

This will work .

String Name = txtName.getText();
String Surname = txtSurname.getText();  


st.executeUpdate("DELETE from list WHERE Name='"+Name"' and Surname='"+Surname"'");

I fixed it like that:

st.executeUpdate("DELETE from list WHERE Name='"+txtName.getText()+"'" + "and Surname='" + txtSurname.getText()+"'");

Thank you all
