MariaDB - Divide (/) Operator

The MariaDB / (divide) operator is used to divide two values. It operates on numerical values.

The example below describes how to use divide operator in various conditions:

Example:

Consider a database table called Sample with the following records:

• Using with WHERE Clause: To select records of table where division of Var1 column value by Var2 column value is greater than 6.0, the query is given below.

  SELECT * FROM Sample
  WHERE Var1 / Var2 > 6.0;
  

  
  

  The query will produce following result:

  Data	Var1	Var2
  Data1	10.0	1.0
  Data2	15.0	2.0
  Data3	20.0	3.0
  Data4	25.0	4.0

• Using with AS Clause: The division of Var1 column value by Var2 column value can be displayed in a different column using AS clause:

  SELECT *, (Var1 / Var2) AS Division FROM Sample;
  

  
  

  The query will produce following result:

  Data	Var1	Var2	Division
  Data1	10.0	1.0	10.0
  Data2	15.0	2.0	7.5
  Data3	20.0	3.0	6.66666666666667
  Data4	25.0	4.0	6.25
  Data5	30.0	5.0	6.0
  Data6	35.0	6.0	5.83333333333333

• Using with UPDATE Clause: To update the column Var1 with the division of Var1 column value by Var2 column value, the query is given below:

  UPDATE Sample
  SET Var1 = Var1 / Var2;
  
  --See result
  SELECT * FROM Sample;
  

  
  

  The query will produce following result:

  Data	Var1	Var2
  Data1	10.0	1.0
  Data2	7.5	2.0
  Data3	6.66666666666667	3.0
  Data4	6.25	4.0
  Data5	6.0	5.0
  Data6	5.83333333333333	6.0

• Using with values: To divide two values, we can simply use SELECT statement:

  SELECT 50 / 25;
  

  
  

  The query will produce following result:

  50 / 25
  2
