Application Security Testing: An Integral Part of DevOps

Data Type

How do I compare two values when one value(data type) is char and the other is an integer?

For this you can use the CONVERT function. Since you can't convert character data to numbers, you'll have to convert the integer column to character. Assuming you have a table called TestTable with two columns:

IntCol int
CharCol char(10)

with these values

IntCol   CharCol
------   -------
1         1
2         2
3         xyz
4         5
You can use this query to SELECT rows based on a comparison:
FROM TestTable
WHERE CONVERT(char(10), IntCol) = CharCol

IntCol      CharCol    
----------- ---------- 
1           1         
2           2
