Declare @Temp1 as nvarchar(max) = '[10004120][1100][10033583][1005]'
Declare @Temp2 as nvarchar(max) = '[10004120][1100]'
If @Temp1 like @Temp2 + '%'
Print 'Yup'
Why does this not work? I don't get the "yup" message.

The SQL LIKE Operator The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. There are two wildcards often used in conjunction with the LIKE operator: The percent sign (%) represents zero, one, or multiple characters. The underscore sign (_) represents one, single character.
You can use the % and _ wildcards with the SQL LIKE statement to compare values from a SQL table. Here is the basic syntax for the SQL Like statement. The % matches zero, one or more characters while the _ matches a single character.
There are two wildcards used in conjunction with the LIKE operator. The percent sign represents zero, one, or multiple characters. The underscore represents a single number or character. These symbols can be used in combinations.
This doesn't work because the brackets in the string have a special function in a LIKE statement - items between the brackets constitute a set of values that the singular character at the specified position matches. Your original pattern looks for a 1,0,4, or 2 followed by a 1 or an 0. To make this work, you should have a pattern like this:
Declare @Temp2 as nvarchar(max) = '[[]10004120][[]1100]'
You have the like backwards. The pattern is the second operand. The logic should be:
@temp1 like @temp2 + '%'
