Here, we have learned different methods for converting integers to strings in SQL Server. ![]() Output to the above SQL statement is shown below in Figure 3. Here is an example to convert an integer to a string using the STR function: SELECT STR(987654, 10, 0) The syntax for this function is as follows: STR(number, length, decimal) The STR function is used to convert a number to a string. Output to the above SQL statement is shown below in Figure 2. ![]() Here is an example to convert an integer to a string using the CONVERT function: SELECT CONVERT(VARCHAR(10), 123456) The syntax for this function is as follows: CONVERT (data_type, expression ) The CONVERT function can also convert an integer to a string. Output to the above SQL statement is shown below in Figure 1. Here is an example to convert an integer to a string using the CAST function: SELECT CAST(123 AS VARCHAR(10)) The syntax for this function is as follows: CAST (expression AS data_type ) The CAST function can be used to convert an integer to a string. There are several ways to convert an integer to a string. ![]() These functions allow you to convert an integer to a string for use in string operations or display purposes. An integer can be converted to a SQL server string using built-in functions like CAST, CONVERT, and STR. Whether working with single or multiple integers, you will learn how to easily convert them to strings using SQL Server. That is to say, we can implicitly cast an INTEGER to a BIGINT, but not the other way around.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. Generally, implicit casts only cast upwards. The integer is converted into a double before being passed to the sin function. This function takes as input argument a column of type DOUBLE, however, it can be called with an integer as well: sin(1). This happens for example when a function is called with an argument that does not match the type of the function, but can be casted to the desired type.Ĭonsider the function sin(DOUBLE). If the expression can't be converted, the function returns undefined. ![]() Numbers in JSON must be an integer or a floating point. In many situations, the system will add casts by itself. String expressions are parsed as a JSON number expression. TRY_CAST will never throw an error, and will instead return NULL if a cast is not possible. TRY_CAST can be used when the preferred behavior is not to throw an error, but instead to return a NULL value. For example, trying to cast the string 'hello' to an INTEGER will result in an error being thrown. Casts may also throw errors when the cast could not be successfully performed. For example, it is not possible to convert an INTEGER to a DATE. For example, when casting from VARCHAR to any other type, the string will be attempted to be converted. The exact behavior of the cast depends on the source and destination types. SELECT CAST ( i AS VARCHAR ) FROM generate_series ( 1, 3 ) tbl ( i ) - "1", "2", "3" SELECT i :: DOUBLE FROM generate_series ( 1, 3 ) tbl ( i ) - 1.0, 2.0, 3.0 SELECT CAST ( 'hello' AS INTEGER ) - Conversion Error: Could not convert string 'hello' to INT32 SELECT TRY_CAST ( 'hello' AS INTEGER ) - NULL
