Question

我有仓库位置，我想查询并只返回奇数或偶数位置。我的表看起来像这样：



LOCN  AISLE BAY LVL POSN
F0201A1 F02 1   A   1
F0203A2 F02 3   A   2
F0204A3 F02 4   A   3
F0205B1 F02 5   B   1
F0206B2 F02 6   B   2
F0207B3 F02 7   B   3
F0208C1 F02 8   C   1
F0209C2 F02 9   C   2
F0209C3 F02 9   C   3

Answer 1

已编辑以匹配字段名称

SELECT * FROM table WHERE BAY % 2 = 0;

返回偶数号码。

SELECT * FROM table WHERE BAY % 2 = 1;

返回奇数编号的海湾。

Answer 2

你的问题不是很干净。购买我假设您有包含整数（街道数量）

的数字的列

使用模数。

像这样：

SELECT number FROM locations WHERE number % 2 = 1

Answer 3

想出来：

SELECT locn_brcd FROM locn_hdr WHERE locn_brcd BETWEEN 'F0654' AND 'F0679' and  lvl in ('D', 'E', 'F')  and posn in ('1', '2') and mod(bay,2) = 0;

SELECT locn_brcd FROM locn_hdr WHERE locn_brcd BETWEEN 'F0569' AND 'F0580' and  lvl in ('D', 'E', 'F') and mod(bay,2) = 1

查询以显示奇数或偶数值
