create table if not exists syntax error

CREATE TABLE IF NOT EXISTS TempA (id int);
CREATE TABLE IF NOT EXISTS TempB (id int);

For some reason the above statements are giving me syntax errors?

I want to create table only if it does not already exist.

Also, can the same "if not exists" clause be applied to "DROP TABLE" and "TRUNCATE" ?

thx in advance .

IF NOT EXISTS
( SELECT [name]
FROM sys.tables
WHERE [name] = MyTable
)
CREATE TABLE MyTable (Col1 int IDENITY, etc. )

Use 'IF EXISTS' test to TRUNCATE or DROP.
