LOG10 Function in SQL

The LOG10() is a mathematics function which returns the logarithm of the specified number to base 10.

Syntax of LOG10 Function

In this SELECT syntax, we have to pass that numeric number in the function whose log 10 value we want to find.

In the Structured Query Language, we can also use the LOG10 function in SELECT query with the table field:

In this SELECT query, we have to define the name and field of that table on which we want to perform the LOG10 function.

Examples of LOG10 function

Example 1: This example gets the log 10 of 1:

Output:

Example 2: This example returns the logarithm of 10 by base 10 in the output:

Output:

Example 3: This example returns the logarithm of 8 by base 10 in the output:

Output:

Example 4: This example returns the logarithm of 255 by base 10 in the output:

Output:

Example 5: This example uses the LOG10 function with the SQL table. In this example, we will create the new table through which we will perform the LOG10 function on the numeric fields of the table.

The following shows the syntax to create the new table in SQL:

The following CREATE statement creates the Product_Details table for storing the price and quantity of products:

The following multiple INSERT queries insert the records of products with their selling and purchasing price into the Product_Details table:

The following SELECT statement displays the inserted records of the above Product_Details table:

Query 1: The following SELECT query uses the LOG10 function with the Product_Quantity column of the above Product_Details table:

This query shows the log 10 value of id of each product.

Output:

Query 2: The following SELECT query uses the LOG10 function with the and Purchasing_Price column of the above Product_Details table:

This query shows the log 10 value of purchasing price of each product.

Output:

Query 3: The following SELECT query uses the LOG10 function with the Product_Rating column of the above Product_Details table:

This query shows the log 10 value of rating of each product from the above table.

Output:

Query 4: The following SELECT query uses the LOG10 function with the Product_Quantity column of the above Product_Details table:

This query shows the log 10 value of quantity of each product from the above table.

Output:

Query 5: The following SELECT query uses the LOG10 function with the and Purchasing_Price and Selling_Price column of the above Product_Details table:

This query shows the log 10 value of selling price of each product.

Output:
