Dear Pinal,
You make SQL Server much simpler than it seems.
I am a hard core fan of you. I found your blog few years back when I was a Sr. Software Engineer. It helped me a lot, later also- when I was the Sr.System Analyst in my previous company. Now working as the incharge of a division. Still loves to read your blog. You are such a nice guy worth being always being with you.

The helps you have done for me yet are beyond words.

I hope once we well meet…

My heart felt thanks,

Mahesh

Hi Yogesh,

The way for backing up a single table with a single Query is as follows:-

SELECT * INTO [xxxx] FROM [yyyy]

Note:-
1) [xxxx] is the new table for backup
2) [yyyy] is the existing table from which backup needs to be
created

[...] Relational Data Base Management Systems (RDBMS) are database management systems that maintain data records and indices in tables. Relationships may be created and maintained across and among the data and tables. In a relational database, relationships between data items are expressed by means of tables. Interdependencies among these tables are expressed by data values rather than by pointers. This allows a high degree of data independence. An RDBMS has the capability to recombine the data items from different files, providing powerful tools for data usage. (Read More Here) [...]

Oracle and SQL Server are not RDBMSs! The defining feature of a relational database is that its data structures are all Relations (thus “relational”). Relations consist of values within tuples.

That is not the model used by SQL-based DBMSs. SQL contains many things that are not relational: duplicate rows, duplicate columns, nulls, tables without keys, etc.

SQL borrows certain ideas and terminology from the relational model but the SQL features are quite different from their relational counterparts. For example SQL queries are not true projections, the SQL constraint called “PRIMARY KEY” is not the same thing as a relational primary key, etc.
