I handle projects by code (PROYECT_A A00001)
There are 3 tables (SEGMENT SE00001,LABLE LA00001,STRONG ST00001) that relate to a project, there may be repeated codes from these tables but they belong only to a project
Is there any way to not repeat the fields?

create a single table with Type column to differentiate the records whether it belongs to SEGMENT,LABLE or STRONG.
CREATE TABLE [dbo].[SEGMENT](
[ID_SEGMENT] [int] IDENTITY(1,1) NOT NULL,
[Type] as Varchar(15) -- Here `SEGMENT`,`LABLE` or `STRONG`
[CODE_SE] AS (case type
when 'Segment' then 'SE'
when 'LABLE' then 'LA'
else 'ST'

I have a requirement to design a table that is going to have around 80 million records. I created a partition for every month using persisted column (if its wrong suggest me the best way). Please find below scripts that I used to create tables and partition and the query that's going to be used often. Only Insertion and deletion will be done on this table.
-- Create the Partition Function
CREATE PARTITION FUNCTION PF_Invoice_item (int)
AS RANGE LEFT FOR VALUES (1,2,3,4,5,6,7,8,9,10,11,12);

CREATE PARTITION SCHEME PS_Invoice_item
AS PARTITION PF_Invoice_item ALL TO ([Primary]);

What is the best way to create index? Shall I create separate non clustered index for each filter, or shall I have Composite index and shall I have covering index to avoid key lookup?
I have a sql script that creates tables for each db in my sql server. However it fails on one create table script. Eg the
CREATE TABLE [dbo].[Mx_Poll_Tags]
command. What is wrong with this? I don't see it.
The weird part is when I one by one run the scripts in a query window they all work fine. Only is this particular proc it fails.
The error states:
Msg 173, Level 15, State 1, Line 71
The definition for column 'Unit' must include a data type.
The create script is made by SQL Server itself by scripting an existing Mx_Poll_Tags table as CreateTo.
Does anyone see what the error is?

Can you try it with just creating that table?
Also, can you eliminate the "begin" and "end"? Based on this thread: http://www.sqlservercentral.com/Forums/Topic808714-8-1.aspx
I don't have enough reputation to make this a comment.
EDIT:
By default, sys.sp_MSforeachdb #command1 has a parameter length of nvarchar(2000). Even though you're passing in a varchar(max), anything over 2000 is being truncated.
How can I alter a table's primary identity column to include a letter before the number? I have a table named vendor_master with a primary key VendorID that I would like to store as v1,v2,v3 and so on
CREATE TABLE [dbo].[vendor_master](
[vendorID] [int] IDENTITY(1,1) NOT NULL,
[Vname] [nvarchar](50) NOT NULL,
[Email] [nvarchar](50) NOT NULL,
[Mobile] [bigint] NULL,
[Landline] [bigint] NULL,
[Address] [nvarchar](max) NOT NULL,
[Pincode] [int] NOT NULL)
If it's important to you to have the field in your table, try the following:
CREATE TABLE [dbo].[vendor_master]
(
[vendorID] [int] IDENTITY(1,1) NOT NULL,
[Vname] [nvarchar](50) NOT NULL,
[Email] [nvarchar](50) NOT NULL,
[Mobile] [bigint] NULL,
[Landline] [bigint] NULL,
[Address] [nvarchar](max) NOT NULL,
[Pincode] [int] NOT NULL,
[VendorKey] AS ('v' +CONVERT([varchar](10),[vendorID])) PERSISTED
)
Of course, that will yield you some weird results when sorting, so you might consider padding the data with zeroes to make it a consistent length:
CREATE TABLE [dbo].[vendor_master]
(
[vendorID] [int] IDENTITY(1,1) NOT NULL,
[Vname] [nvarchar](50) NOT NULL,
[Email] [nvarchar](50) NOT NULL,
[Mobile] [bigint] NULL,
[Landline] [bigint] NULL,
[Address] [nvarchar](max) NOT NULL,
[Pincode] [int] NOT NULL,
[VendorKey] AS ('v' +RIGHT('000000000' + CONVERT([varchar](10),[vendorID]),10)) PERSISTED
)
You can't actually do what you are asking. Anyway, there is no reason to add the same letter to the front of a fields value. Instead add the letter in your SELECT statment:
SELECT CONCAT('v', vendorID) AS VendorIDWithPrefix, Vname, Email, Mobile
FROM vendor_master

Do you have an index on EnquiryId and CourseID?
Seeing as you are joining, ordering and partitioning by it you really should.
CREATE INDEX IDX_AGAM_AceOFPace_EnquiryID
ON AGAM_AceOFPace (EnquiryID)
CREATE INDEX IDX_AGAM_AceOFPace_CourseID
