A zero-length binary string can be specified as 0x without any byte values specified in the hexadecimal constant. Concatenating a zero-length string always concatenates the two specified strings. When you work with strings with a null value, the result of the concatenation depends on the session...

resulting in an invalid XML. This is due to the way SQL Server performs implicit string conversions when concatenating strings. When all the string literals/variables involved in the concatenation are 8000 characters or less, the resulting string will be exactly 8000 characters. ...

This function was introduced in SQL Server 2017. It’s purpose is to concatenate values in a string expression and place separators / delimiters between each value. The Microsoft documentation for this function: https://learn.microsoft.com/en-us/sql/t-sql/functions/string-agg-transact-sql?view...
String concatenation is shown with the || operator, taken from PL/I. However, you can also find the plus sign being overloaded in the Sybase/SQL Server family and some products using a function call like CONCAT(s1, s2) instead. The SUBSTRING(< string > FROM < start > FOR < length >...
