# CEILING Function in SQL

The CEILING function in Structured Query Language returns the smallest integer value which is greater than or equal to the given number.

### Syntax of CEILING Function

Syntax1: This syntax uses the CEILING function with the column name of the SQL table:

In this syntax, we have to specify the name of that integer column on which we want to execute the CEILING numeric function.

Syntax2: This syntax uses the CEILING function with the integer or decimal value:

### Examples of CEILING function

Example 1: This example returns the ceiling value of the specified number:

Output:

ceiling_Value_of_0.5
1

Example 2: This example returns the ceiling value of all the numbers between 21 and 30:

Output:

21.8 22.9 23.58 24.55 25.05 26 27.125 28.98 29.89 30.02
22 23 24 25 26 27 28 29 30 31

Example 3: This example uses the ceiling function with the SQL table.

In this example, we will create the new table through which we will perform the ceiling function on the columns 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:

Product_ID Product_Name Product_Quantity Purchasing_Price Selling_Price Release_Date Product_Rating
0.1 P1 36.250 15.5 NULL 2022-04-30 NULL
0.2 P4 75.500 2.45 14.8 2022-01-28 9.25
0.3 P2 68.350 95.85 12.250 2022-02-18 9.15
0.4 P7 48.850 85.355 NULL 2021-12-25 8.45
1.5 P6 35.900 0.5 0.500 2021-10-15 NULL
2.6 P8 20.750 112.110 9.95 2022-01-28 9.9
0.7 P10 12.250 999.550 0.258 2022-04-11 NULL

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

This query shows the ceiling value of product id of each product.

Output:

Product_ID ceiling_Value_of_Product_ID
0.1 1
0.2 1
0.3 1
0.4 1
1.5 2
2.6 3
0.7 1

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

This query shows the ceiling value of Purchasing and selling price of each product from the above table.

Output:

15.5 16 NULL â€“
2.45 3 14.8 15
95.85 96 12.250 13
85.355 86 NULL â€“
0.5 1 0.500 1
112.110 113 9.95 10
999.550 1000 0.258 1

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

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

Output:

Product_Rating ceiling_Value_of_productrating
NULL â€“
9.25 10
9.15 10
8.45 9
NULL â€“
9.9 10
NULL â€“

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

This query shows the ceiling value of product quantity of each product.

Output:

Product_Quantity ceiling_Value_of_Product_Quantity
36.250 37
75.500 76
68.350 69
48.850 79
35.900 36
20.750 21
12.250 13
