Part one of a four-part series of blogs

There are various ways to insert data into new or existing tables in T-SQL - this blog gives examples of each.

  1. Inserting Data into Tables using SQL (this blog)
  2. Inserting Single Records into a Table
  3. Inserting Multiple Rows of Data into a Table

Inserting Data into Tables using SQL

A previous blog showed how to create tables using SQL - this one shows how to populate them with data.

When I was first learning SQL, these were some of the commands that I found the hardest to remember.  The problem is that there are 3 ways to do this, and each does a different thing.  The 3 ways are:

Method What it does
INSERT INTO ... VALUES Inserts a single record into a table.
INSERT INTO ... SELECT Adds a set of rows into a table.
SELECT ... INTO Creates a new tables from a set of rows.
The last two methods use similar syntax, and are particularly easy to confuse.

Aficionados (aficionadi?) of Access should note that the above methods correspond to append and make-table queries.

This blog will consider each of the 3 methods shown above in turn!
