Column name or number of supplied values does not match table definition

They don't have the same structure... I can guarantee they are different

I know you've already created it... There is already an object named ‘tbltable1’ in the database

What you may want is this (which also fixes your other issue):

Drop table tblTable1

select * into tblTable1 from tblTable1_Link

I want to also mention that if you have something like

insert into blah
       select * from blah2

and blah and blah2 are identical keep in mind that a computed column will throw this same error...

I just realized that when the above failed and I tried

insert into blah (cola, colb, colc)
       select cola, colb, colc from blah2

In my example it was fullname field (computed from first and last, etc)

for inserts it is always better to specify the column names see the following

DECLARE @Table TABLE(
        Val1 VARCHAR(MAX)
)

INSERT INTO @Table SELECT '1'

works fine, changing the table def to causes the error

DECLARE @Table TABLE(
        Val1 VARCHAR(MAX),
        Val2 VARCHAR(MAX)
)

INSERT INTO @Table SELECT '1'

Msg 213, Level 16, State 1, Line 6 Insert Error: Column name or number of supplied values does not match table definition.

But changing the above to

DECLARE @Table TABLE(
        Val1 VARCHAR(MAX),
        Val2 VARCHAR(MAX)
)

INSERT INTO @Table (Val1)  SELECT '1'

works. You need to be more specific with the columns specified

supply the structures and we can have a look

The problem is that you are trying to insert data into the database without using columns. SQL server gives you that error message.

Error: insert into users values('1', '2','3') - this works fine as long you only have 3 columns

If you have 4 columns but only want to insert into 3 of them

Correct: insert into users (firstName,lastName,city) values ('Tom', 'Jones', 'Miami')
