I wrote this SQL
select *
from t_info
where contract_id <> "" and status <> "unfinished"
order by id asc;
but it takes more than 4s. I wonder how to improve this SQL? Thank.
Please don't use "<>" in where condition, while you need to use index.
select * from t_info
where LENGTH(trim(contract_id)) > 0
and (not status = "unfinished")
order by id asc;

So I have a table for biddings, you can win the bidding by posting the lowest unique bid. So if 2 people place a bet of $1, none of them win, if 1 person places a bet of $2, this guy wins. But how can I check this in MySQL?
Assume your table has the bid value stored in the field name bet, then below is a worked solution:
SELECT * FROM YourTableName
WHERE bet = (SELECT MIN(bet) FROM YourTableName)
GROUP BY bet
HAVING COUNT(*) = 1;

I am having a database with 2 columns employee and job.Job column contains character in each record.In that,I have to list the employees whose job is having last 3 characters as 'man'.I have to use only functions in SQL Query.
Use LIKE with wildcard:
SELECT *
FROM your_table
WHERE job_column_name LIKE '%man'
or using RIGHT
SELECT *
FROM your_table
WHERE RIGHT(job_column_name, 3) = 'man'
Answer For Question 4 is
SELECT *
FROM emp
WHERE SUBSTR(job,-3,3)='MAN';
