SQLite 算術運算符

假設變量A=10和變量B=20,那麼SQLite的算術運算符將用於如下:

運算符 描述 實例
+ Addition - Adds values on either side of the operator a + b will give 30
- Subtraction - Subtracts right hand operand from left hand operand a - b will give -10
* Multiplication - Multiplies values on either side of the operator a * b will give 200
/ Division - Divides left hand operand by right hand operand b / a will give 2
% Modulus - Divides left hand operand by right hand operand and returns remainder b % a will give 0

示例

下麵是簡單的例子顯示使用SQLite的算術運算符:

sqlite> .mode line
sqlite> select 10 + 20;
10 + 20 = 30


sqlite> select 10 - 20;
10 - 20 = -10


sqlite> select 10 * 20;
10 * 20 = 200


sqlite> select 10 / 5;
10 / 5 = 2


sqlite> select 12 %  5;
12 %  5 = 2
