一简单查询,请各位帮忙!

[peppi]

有个表,如下:
A B
--------
a 1
b 2
w 1
4 1
我想查出B字段里为"1"的个数来,该怎么写SELECT呢?

[zlbjack]

select count(*) from table1 where b='1'

[comicgirl]

select count(*) from table where b='1'

[microlong]

DECLARE @a INT
SET @A=(select count(*) from table where b='1')
PRINT '@A'

[ptpa]

select count(*) from table1
where b='1'

[lxinjun]

select sum(b) as gs from table where b=1

[Yang_]

SEELCT COUNT(*) FROM TABLENAME WHERE B='1'
