How to enter special characters like "&" in oracle database? [duplicate]

Solution 1:

If you are in SQL*Plus or SQL Developer, you want to run

SQL> set define off;

before executing the SQL statement. That turns off the checking for substitution variables.

SET directives like this are instructions for the client tool (SQL*Plus or SQL Developer). They have session scope, so you would have to issue the directive every time you connect (you can put the directive in your client machine's glogin.sql if you want to change the default to have DEFINE set to OFF). There is no risk that you would impact any other user or session in the database.

Solution 2:

Try 'Java_22 '||'&'||' Oracle_14'

Solution 3:

Justin's answer is the way to go, but also as an FYI you can use the chr() function with the ascii value of the character you want to insert. For this example it would be:

INSERT INTO STUDENT(name, class_id) VALUES ('Samantha', 'Java_22 '||chr(38)||' Oracle_14'); 

Solution 4:

you can simply escape & by following a dot. try this:

INSERT INTO STUDENT(name, class_id) VALUES ('Samantha', 'Java_22 &. Oracle_14');

Solution 5:

To Insert values which has got '&' in it. Use the folloiwng code.

Set define off;

Begin

INSERT INTO STUDENT(name, class_id) VALUES ('Samantha', 'Java_22 & Oracle_14');

End ;

And Press F5 from Oracle or Toad Editors.
