Thus, we can say LOWER function does not affect numbers or special characters. However, the numbers and special characters remain unaffected. It has changed only uppercase letters and converted them to lowercase. The function would not do nothing anything and return to the original text string because it is already in lower case. In this example, we will see how function responds, if the text string is already in lower case. The function has converted all the letters into small case and returns text string as “this is sample text”. Now what will happen if we use LOWER function? In this example, we have a cell with text in mixed letters. The argument is required for function to perform the action. Note: The function takes only single argument which is a text argument, and it can either be a cell reference to the location in the worksheet or supplied directly to the argument. The function has converted all the characters into small letters. We have taken all the characters in capital letters. In this example, we will see how LOWER function works. Let’s take a look at few examples and understand how to use this function in Excel. LOWER function converts all letters from uppercase (capital letters) to lowercase in a text string. I am always interested in new challenges so if you need consulting help, reach me at all posts by Rajendra GuptaIn this, article we will learn about LOWER function in Microsoft Excel.

Let’s use a few more examples with this function and observe the output. It increments the value of the parameter and moves next in the while loop The gets the character one step behind and does not perform any conversion to uppercase. If the value of the parameter is greater than 1, parameter gets the particular character from the text If the value is 1, then it sets the value for as moves to next If block and finds the value of as so it replaces the first character as upper case It gets the first character in the variable using the substring function It starts at value 1 and goes up to 35 to perform the following task LEN function calculates the length of the string using It returns value 35 for the current string We define the text in a variable and define a few other variables and function converts all text into lowercase using SQL Lower fruits:- apple mango orange banana Let’s understand this function and see how it works. In the following screenshot, we can see it coverts the upper case of each word’s first letter. ( 'FRUITS :- APPLE MANGO ORANGE BANANA' ) It converts all characters into capital letters. We use SQL UPPER function to convert the characters in the expression into uppercase. Let’s explore a few available scenarios in the further section of this article. ![]() You might think of a question at this point – Is it possible to covert the character case in SQL Server to an appropriate format. Residential high street, STREET, Market, SA For example, in column, we have Raj (First character capital), sonu (all small case characters) and PAUL (capital letters). In the following table, you can see the different types of inputs from different customers. It does not look good as well if you have to share the report daily to higher management for all newly enrolled customers. We do not see all words following a consistent pattern. Each customer is different so you cannot expect a similar format for all inputs.įor example, you get the following entries in your SQL table. ![]() Each customer provides few mandatory information such as first name, last name, email address and residential address. Customers visit the website and provide their necessary information while creating a login account. ![]() Suppose you have an online shopping website. This article gives an overview of SQL UPPER function and SQL LOWER function to convert the character case as uppercase and lowercase respectively.
