The zero in ten is not even checked because is it alphabetizing when ordering these fields. So the number 10 would come before the number 2. This is happening because a string is evaluated as alphabetical when sorted. You will also notice 2.2.0 should be before 2.10.0. Instead you can see it is lower in the order due to the string order. You want the number 1.1.2 to come before 1.1.10. Notice the numbers are sorted as a string and not numeric. I could not just convert this code to a number and sort on that, because the codes had multiple decimals as seen in this image below. If you request a conversion that is explicitly forbidden, the TRY CONVERT() method will return an error.I was working on a Cube in Analysis Services for a client recently and needed to sort on a field that was a varchar but contained numeric data. If the cast is successful, it returns the value as the given data else, it returns NULL. The TRY_CONVERT() method attempts to convert the value supplied to it to the data type specified. Query: SELECT TRY_CAST('1234abc' as INT) as Result Query: SELECT TRY_CAST('1234' as INT) as Result data_type: Valid data type into which the function will cast the expression.Syntax : TRY_CAST ( expression AS data_type ) However, if you request a conversion that is not valid, the TRY_CAST() method will return an error. If the cast is successful, it returns the value in the provided data else, it returns NULL. The TRY_CAST() function attempts to cast the input value to a value of the given data type. Now Lets us discuss a more efficient approach to convert the values from one data type to another using SQL Server’s TRY_CAST() and TRY_CONVERT() function: TRY_CAST() SQL Query to Update All Columns in a Table.Compare SQL Server Results of Two Queries.How to Select Individual Columns in SQL?.
