I search in google and found this error occurs may because of "{}", But how can I call a oracle procedure without "{}" ? or which token should I use ?
The braces won't work for Oracle. Take them out and you should be good to go. Oracle traditionally uses placeholders that being with the character ':' followed by a word.
If you don't like the call keyword, you can use this: "BEGIN get_id(?,?,?); END;"
