How do I get string functions supported by database?

package org.kodejava.jdbc;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.DatabaseMetaData;
import java.sql.SQLException;

public class StringFunction {
    private static final String URL = "jdbc:mysql://localhost/kodejava";
    private static final String USERNAME = "kodejava";
    private static final String PASSWORD = "s3cr*t";

    public static void main(String[] args) {
        try (Connection connection =
                     DriverManager.getConnection(URL, USERNAME, PASSWORD)) {
            DatabaseMetaData meta = connection.getMetaData();

            // Get string functions supported by database
            String[] functions = meta.getStringFunctions().split(",\\s*");

            for (String function : functions) {
                System.out.println("Function = " + function);
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

Here are the string functions supported by MySQL database:

Function = ASCII
Function = BIN
Function = BIT_LENGTH
Function = CHAR
Function = CHARACTER_LENGTH
Function = CHAR_LENGTH
Function = CONCAT
Function = CONCAT_WS
Function = CONV
Function = ELT
Function = EXPORT_SET
Function = FIELD
Function = FIND_IN_SET
Function = HEX
Function = INSERT
Function = INSTR
Function = LCASE
Function = LEFT
Function = LENGTH
Function = LOAD_FILE
Function = LOCATE
Function = LOCATE
Function = LOWER
Function = LPAD
Function = LTRIM
Function = MAKE_SET
Function = MATCH
Function = MID
Function = OCT
Function = OCTET_LENGTH
Function = ORD
Function = POSITION
Function = QUOTE
Function = REPEAT
Function = REPLACE
Function = REVERSE
Function = RIGHT
Function = RPAD
Function = RTRIM
Function = SOUNDEX
Function = SPACE
Function = STRCMP
Function = SUBSTRING
Function = SUBSTRING
Function = SUBSTRING
Function = SUBSTRING
Function = SUBSTRING_INDEX
Function = TRIM
Function = UCASE
Function = UPPER
