"ORA-00928: missing SELECT keyword" error while using sequence function

Sorry I am new to SQLPlus stuffs! So here, I have a table called iowe, i have a four records pre-loaded into it. This is how it looks like: ``` NAME AMOUNT Serial Number ---------- ---------- ------------- Praveen 20500 1 Roshan 5000 2 Rohit 5000 3 Shashi 8000 4 ``` Until I entered these four records, I did not know about the sequence function in SQL. So I tried implying it into this table. I wanted to input a new record, say "XXX" in name, 500 in Amount, and using the sequence command, i wanted the "Serial Number" to be auto incremented. So I created a sequence called `iowesqn`, which looks like this, when i `select * from user_sequences`: ``` SEQUENCE_NAME MIN_VALUE MAX_VALUE INCREMENT_BY C O CACHE_SIZE LAST_NUMBER ------------------ ---------- ---------- ------------ - - ---------- ----------- SQN 1 5 2 N N 0 3 IOWESQN 1 1.0000E+27 1 N N 0 7 ``` (Please disregard the sequence `SQN`) To insert the sequence `IOWESQN`, I used this command: ``` insert into iowe(name, amount, "Serial Number") values('XXX', 500, iowesqn.nextval) ``` Everything works fine. The column Serial Number increments fine by 1 on every entry. However, when i try `insert into iowe ('&name', '&amount', "Serial Number") value(iowesqn.nextval));`, it asks me fr the name, and the amount but right then (after the amount is input), it throws an error. It reads: ORA-00928: missing SELECT keyword This is whole thing that comes up after the amount it input: ``` old 1: insert into iowe ('&name', '&amount', "Serial Number") value(iowesqn.nextval)) new 1: insert into iowe ('ret', 'ert', "Serial Number") value(iowesqn.nextval)) insert into iowe ('ret', 'ert', "Serial Number") value(iowesqn.nextval)) ERROR at line 1: ORA-00928: missing SELECT keyword ``` Please tell me what I am (or (highly unlikely) it is) doing wrong. Thanks in advance.
