How Do You Convert Commands In SQL?
Convert commands in SQL give programmers the ability to switch from one data type to another. There are two main convert statements in SQL: convert and cast. These two statements provide the same functionality. Although the convert command is more commonly used, the cast statement is still supported and exists in older stored procedure code. Create a basic query that selects a number. For this example, a number is converted to a string (a string is a varchar is SQL). Below is a basic query for a number: select total_price from order Use the convert function to convert the total to a varchar. The following SQL syntax retrieves the decimal value in the total_price column and converts it to a varchar with 10 characters: select convert(varchar(10), total_price) from order Convert the total into a varchar using the cast function. The cast function has slightly different syntax than convert.
