Convert Integer to String in SQL Server

In this article, you will learn how to convert an integer to a string in SQL Server.

Introduction

In this article, we will learn the different methods for converting an integer to a string in SQL Server and provide examples for each method. Whether working with single or multiple integers, you will learn how to easily convert them to strings using SQL Server. An integer can be converted to a SQL server string using built-in functions like CAST, CONVERT, and STR. These functions allow you to convert an integer to a string for use in string operations or display purposes.

Convert an integer to a string

There are several ways to convert an integer to a string. Here are a few methods:

Method 1: Using the CAST function

The CAST function can be used to convert an integer to a string. The syntax for this function is as follows:

CAST (expression AS data_type [(length)])

Here is an example to convert an integer to a string using the CAST function:

SELECT CAST(123 AS VARCHAR(10))

Output to the above SQL statement is shown below in Figure 1.

Method 2: Using the CONVERT function

The CONVERT function can also convert an integer to a string. The syntax for this function is as follows:

CONVERT (data_type [ (length) ], expression [, style ])

Here is an example to convert an integer to a string using the CONVERT function:

SELECT CONVERT(VARCHAR(10), 123456)

Output to the above SQL statement is shown below in Figure 2.

Method 3: Using the STR function

The STR function is used to convert a number to a string. The syntax for this function is as follows:

STR(number, length, decimal)

Here is an example to convert an integer to a string using the STR function:

SELECT STR(987654, 10, 0)

Output to the above SQL statement is shown below in Figure 3.
