Now, we will go into the point with a simple example. CONCAT function is a SQL string function that provides to concatenate two or more than two character expressions into a single string. CONCAT function in SQL is one of the most useful members of these functions. SQL string functions are used to manipulate the character expressions or to obtain various information about them. We can use nvarchar(max) or varchar(max) instead. These data types are deprecated, and for this reason, we should try not to use these data types.
We have to take into account one point about the text and ntext data types. Unicode character strings data types that store Unicode character data These are:Ĭharacter strings data types that store non-Unicode character data In terms of SQL Server, we can categorize SQL string data types into different two groups. From the simple CAST function to the nuanced CONCAT and FORMAT combinations, you now have a comprehensive toolkit for performing this conversion.In this article, we will explore the syntax, working mechanism and other details of the CONCAT function in SQL and we will also make up various different examples about it.Ī string is a set of characters that helps to declare the texts in the programming languages. In this blog, we've covered the process of converting INT to VARCHAR in MySQL through various methods. This method combines CONCAT and CAST while including string literals to achieve the INT to VARCHAR conversion: SELECT CONCAT('Value: ', CAST(int_column AS CHAR)) AS varchar_columnīy incorporating string literals, you can add additional context or labels to your converted VARCHAR column. Method 5: Using CONCAT and CAST with String Literals While its primary purpose is to format numbers with thousands separators and decimal points, we can also use it to convert INT to VARCHAR: SELECT FORMAT(int_column, 0) AS varchar_columnīy setting the decimal places parameter to 0, we instruct the FORMAT function to return an integer-like string representation of the INT column. MySQL's FORMAT function provides a powerful way to format numbers. This method is similar to Method 1 but showcases how functions can be combined creatively. Here, we first cast the INT column to CHAR and then concatenate an empty string to perform the conversion.
In this method, we combine the CAST function with CONCAT to convert INT to VARCHAR: SELECT CONCAT(CAST(int_column AS CHAR), '') AS varchar_column Method 3: Using CAST with CONCAT Function This method is concise and offers a quick way to achieve the conversion. Method 2: Using CONCAT or CONCAT_WS FunctionĪnother approach involves using the CONCAT or CONCAT_WS (concatenate with separator) function along with an empty string to convert the INT column to VARCHAR: SELECT CONCAT('', int_column) AS varchar_columnīy concatenating an empty string with the INT column, MySQL implicitly converts the INT values to strings. The function takes care of the conversion by transforming each INT value into its corresponding string representation. This method leverages the built-in casting functions to directly convert the INT column to VARCHAR.
Or SELECT CONVERT(int_column, CHAR(255)) AS varchar_column To convert an INT column to VARCHAR, you can use these functions as follows: SELECT CAST(int_column AS VARCHAR(255)) AS varchar_column The CAST and CONVERT functions in MySQL are powerful tools for data type conversion.
