How to get last date of a Month in Sql Server

declare @date varchar(10)

set @date=convert(varchar,year(getdate()))+’-'+convert(varchar,(month(getdate())+1))+’-01′

select dateadd(day,-1,@date)

Logic is which month we want to find the last date take that month.

Suppose i want to find last day of   14-04-2009

Add 1 month to this and create a format of next month first day

the next month will be 05 ,2009

2009-05-01

With dateadd function add -1 day to that function . So it will come to the previous month last day.

dateadd(day,-1,’2009-05-01′)

it will display   ‘2009-04-31‘

creating tables from other tables in sql 2005

Method 1 : INSERT INTO SELECT
This method is used when table is already created in the database earlier and data is to be inserted into this table from another table. If columns listed in insert clause and select clause are same, they are are not required to list them. I always list them for readability and scalability purpose.
USE AdventureWorks
GO
—-Create TestTable
CREATE TABLE TestTable (FirstName VARCHAR(100), LastName VARCHAR(100))
—-INSERT INTO TestTable using SELECT
INSERT INTO TestTable (FirstName, LastName)
SELECT FirstName, LastName
FROM Person.Contact
WHERE EmailPromotion = 2
—-Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
—-Clean Up Database
DROP TABLE TestTable
GO

Method 2 : SELECT INTO
This method is used when table is not created earlier and needs to be created when data from one table is to be inserted into newly created table from another table. New table is created with same data types as selected columns.
USE AdventureWorks
GO
—-Create new table and insert into table using SELECT INSERT
SELECT FirstName, LastName
INTO TestTable
FROM Person.Contact
WHERE EmailPromotion = 2
—-Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
—-Clean Up Database
DROP TABLE TestTable
GO
