I am trying to return the total number of reserved seats in my flightbooking table using a flightID number.
SELECT COUNT(flight.flightid) AS reservedseats FROM flightbooking
WHERE status=R
I get an error saying
ERROR: missing FROM-clause entry for table "flight"
LINE 1: SELECT COUNT(flight.flightid) AS reservedseats FROM flightbo...
What am i doing wrong?
Try:
SELECT COUNT(flight.flightid) AS reservedseats
FROM flightbooking AS flight
WHERE status='R'
You were referring to flight.flightid but there isn't a table with name or alias flight. The engine doesn't know where it should retrieve flightid from.
You were also missing quotes around the char value R.
In your comment you say "I know nothing about SQL". It is much appriciated if you do some research yourself before you come here asking for help.

I'm using Microsoft SQL Server and I"m having issues writing a command for MIN and MAX functions.
It seems simple. The data type of the column is date time and the requested information is to find oldest/newest employee.
Below is the query I wrote:
select max(date_hired)
from staff;
select min(date_hired)
from staff;
But it seems like they are working in reverse. Min is giving me oldest and max is giving me youngest.

I have been trying to learn SQL, and I was learning the DECODE statement:
This is the query I was trying to use:
SELECT DECODE(FIRST_NAME,'Steven','Name is Steven','Neena','Name is Neena','Some other name') AS "NAME" FROM hr.employees;
This query works successfully,but when I try the query:
SELECT DECODE(FIRST_NAME,'Steven','Name is Steven','Neena','Name is Neena','Some other name') AS "NAME" WHERE FIRST_NAME='Steven' FROM hr.employees;
This query gives me the output as:
ORA-00923: FROM keyword not found where expected
Can anyone explain me what's wrong?
Where clause needs to be placed after From clause.
SELECT DECODE(FIRST_NAME,'Steven','Name is Steven','Neena','Name is Neena','Some other name') AS "NAME"
FROM hr.employees
WHERE FIRST_NAME='Steven';

I created table "member". It has two columns name, id and no values. And I'm trying to insert value "spring" into column name!
But It doesn't work...Can anybody help me please?
I wrote like this:
insert into member(name) values("spring");
error is:
Column "spring" not found; SQL statement:
insert into member(name)
values("spring") [42122-200] 42S22/42122
You should use single quotes for your String/Varchar values.
Try this query:
insert into member(name) values('spring');

SELECT INDIVIDUAL.INV_FNAME,

In your query only USER_ID column in the where condition is not specified with a table name. I guess USER_ID is there in multiple table. Try the where condition with proper table name
SELECT INDIVIDUAL.INV_FNAME,
INDIVIDUAL.INV_LNAME,
INDIVIDUAL.INV_IC_NUM,
CUSTOMER.MEMBER_LEVEL,
CUSTOMER.MEMBER_POINT_BALANCE,
CUSTOMER.MEMBER_DISCOUNT_RATE,

Also like #HoneyBadger comment you need to specify the join between the tables
