SQL SERVER – T-SQL Scripts to Find Maximum between Two Numbers

I found there is a simple way to write query to get the maximum of two numbers in SQL Server.

Method 1:

DECLARE @Value1 DECIMAL(5,2) = 9.22
DECLARE @Value2 DECIMAL(5,2) = 8.34
SELECT (0.5 * ((@Value1 + @Value2) + ABS(@Value1 - @Value2))) AS MaxColumn


I thought his logic was accurate but the same script can be written another way. I quickly wrote following code for him and which worked just fine for him.

Method 2:

DECLARE @Value1 DECIMAL(5,2) = 9.22
DECLARE @Value2 DECIMAL(5,2) = 8.34
SELECT CASE WHEN @Value1 > @Value2 THEN @Value1 ELSE @Value2 END AS MaxColumn

For me Method 2 is looks simpler than Method 1.

Place .NET DLL in GAC

Today other team guy has asked me help as he was facing some problem in trying to place a .NET DLL in GAC where he does not have source code with him. Potentially you just have to follow regular steps as mentioned below to place the DLL in GAC; 1. Generating the public key: Go to visualStudio.Net command prompt and type the following command: sn -k keyfile1.snk Here keyfile1.snk is the keyfile we are generating. You can store this key file in the bin folder of the assembly. In order to do this u have to go to the bin folder. For example: C:\foldername\assemblyname\bin sn-k keyfile1.snk By doing this the keyfile is stored in the bin folder. 2. Than place the keyfile into the Assembly. Go to AssemblyInfo.cs file: [assembly: AssemblyKeyFile("C:\foldername\assemblyname\keyfile1.snk")] 3. Then build the Assembly. 4. Placing the assembly into GAC This process is fine when you have source code with you. What if you don't have the source code with you and you need to put it to t...

DataMemberAttribute can be applied to field or a property and theses fields or properties can be either public or private.
