A SQL string function is a function that is applied to a string. It can be used in SQL statements, such as SELECT, INSERT, UPDATE, and DELETE statements in order to filter data.
The following are some examples of some common string functions:
CONCAT(), SUBSTR(), LEFT(), RIGHT()
The benefits of using SQL string functions include:
They can be used to avoid hard-coding values into your queries.
They can also make your queries more readable and concise.
A string function is a function that takes an input of one or more strings and returns a single string. A string method is a function that takes an input of one or more strings and returns a value.
A string function accepts a string value as an input and returns a string value regardless of the data type. There are numerous built-in string functions in SQL Server that developers can use.
String data types are used in SQL to store any form of data in tables. We have the option of allowing customers to store either a fixed number of characters or vast length data in string data types, depending on their needs.
