![]() The fractional part of the number is rounded to one decimal place. The format used to convert between data types, such as a date or string format. The value to convert to another data type. In the above example, STR() converts an expression that is made up of five digits and a decimal point to a six-position character string. The length of the resulting data type (for char, varchar, nchar, nvarchar, binary and varbinary) expression. Syntax STR(float_expression ])Įxample: SELECT STR(123.45, 6, 1) as Num2 STR() is another function in SQL Server that accepts number values and returns them as a varchar expression and character data is right-justified, with a specified length and decimal precision. For more information about the values this parameter can have, see SQL Format Models. If you omit this parameter, TONUMBER returns a floating point. pattern: A string value, either CHAR or VARCHAR, that specifies an output pattern string using one of the supported Template Patterns for Numeric Formatting. Style parameter is used to define the formatting option on the resulting expressions and it accepts integer values to define the formatting. The functions TODECIMAL, TONUMBER, TONUMERIC, and TODOUBLE accept an optional parameter that specifies the format of the input string, if the input expression evaluates to a string. Specifies the string value to convert, either CHAR or VARCHAR. Here is the syntax of Convert() CONVERT(datatype(length), expression, style) Int to varchar using Convert()Ĭonvert() function in SQL Server can also be used to convert a value of one data type to another.Ĭonvert() is more efficient than Cast() since it allows us to additional formatting styles, so CAST is less powerful and less flexible than CONVERT. Next, we are using the Cast() function to convert the variable to the varchar data type of length 10 from int data-type. ![]() So, in the above example, we have declared a variable of integer data type and assigned a value to the variable. This example uses the CAST expression to convert a decimal to an. 1) Converting a decimal to an integer example example. Let’s take some examples of using the CAST expression. Here is an example, in which we will convert intger datatype to varchar using SQL Server Cast() DECLARE INT Code language: SQL (Structured Query Language) (sql) In this syntax, you specify the value and the data type to which you want to convert the value. The Cast() function accepts two values, the first is the expression whose data type a user wants to change, and the second is the resulting data type that a user wants. SELECT CAST (CAST (MyVarcharCol AS NUMERIC (19,4)) AS INT) When copying data from TableA to TableB, the conversion is implicit, so you dont need the second convert (if you are happy rounding down to nearest INT): INSERT INTO TableB (MyIntCol) SELECT CAST. The Cast() in SQL Server, is a function that converts a value of one data type to another. To get around this just do two converts as follows: STRING -> NUMERIC -> INT. If you are working with SQL Server database table, sometimes you may want to convert int datatype into string or int to varchar in SQL Server, so in this article, I have mentioned with article, how you can convert int to string in SQL Server using various examples. ![]()
