根据硬编码值SQL Query Help选择多个元组

Question

I want to use a select statement to grab specific tuples based on their ID. So I want to be able to grab col1 from table1 where id = 1,5,9,15 in one query if thats possible. How might I go about doing this?

Select col1 from table1 where id = 1 and id = 5...

I tried this, but I couldn't get anything. What am I missing?

Thanks!

Answer 1

In a single row, the id can't be both 1 and 5 at the same time. That's impossible, so the query will never match any row.

It can be 1 or 5, though.

SELECT col1 FROM table1 WHERE id = 1 OR id = 5 ...

You can also use the IN syntax:

SELECT col1 FROM table1 WHERE id IN (1, 5, 9, 15)

Answer 2

您想要使用OR而不是AND。

Select col1 from table1 where id = 1 or id = 5...

Answer 3

使用in ：

select col1 from table1 where id in (1, 5, 9, 15);

Answer 4

grab col1 from table1 where id = 1,5,9,15

You want tables IN 1,5,9,15, not =.

WHERE id IN (1,5,9,15)
