The SQL statement `SELECT SUBSTR('123456789', INSTR('abcabcabc','c'), 9) FROM EMP;` is using two functions: `SUBSTR` and `INSTR`.

1. `INSTR('abcabcabc','c')` is a function that returns the position of the first occurrence of the second string in the first string. In this case, it returns the position of 'c' in 'abcabcabc', which is 3.

2. `SUBSTR('123456789', 3, 9)` is a function that extracts a substring from a string. It starts from the position of the second argument and extracts the number of characters specified in the third argument. In this case, it starts from the 3rd character of '123456789' and extracts 9 characters.

However, '123456789' only has 9 characters, so starting from the 3rd character, we can only extract 7 characters. Therefore, the result of `SUBSTR('123456789', 3, 9)` is '3456789'.

So, the SQL statement `SELECT SUBSTR('123456789', INSTR('abcabcabc','c'), 9) FROM EMP;` prints '3456789' for each row in the EMP table.
