How to Correctly Concatenate Numbers and Strings for Number Formatting in T-SQL?

Formatting Numbers using Concatenation in T-SQL

This problem occurs when attempting to concatenate numbers and strings to format numbers in T-SQL. The provided function, ActualWeightDIMS, aims to concatenate ActualWeight and Actual_Dims_Lenght, Actual_Dims_Width, and Actual_Dims_Height to produce a formatted string. However, when invoking this function in a select statement, an error is encountered because of an implicit conversion error during concatenation.

To resolve this error, it is necessary to explicitly convert the integer parameters to VARCHAR before concatenating them. This prevents T-SQL from attempting to perform an addition operation between a number and a string. The following modified portion of the function addresses this issue:

By explicitly casting the integer parameters to VARCHAR, SQL Server interprets the concatenation as a string concatenation, resulting in the desired formatted string output. Additionally, table aliases could be added to the select statement in the question to enhance readability and maintainability.
