When I execute this script, there is a syntax error. What is wrong with this?

use TEST
go

CREATE TABLE newTagsTable 
( 
     (SELECT TEST.dbo.dynamicTags.Alais 
      FROM TEST.dbo.dynamicTags 
      WHERE ID = 2) varchar(200)
);

Answer 1

Is this what you need ?

SELECT Alais 
into newTagsTable 
FROM dynamicTags 
WHERE ID = 2;

Ok, so something like this then:

create procedure test_proc
as
declare @p_sql varchar(2000);
declare @p_sql_2 varchar(2000);
declare @getid CURSOR;

SET @getid = CURSOR FOR
SELECT Alais
FROM   dynamicTags;

begin
    set @p_sql = 'create table newTagsTable (';
    
    OPEN @getid
    FETCH NEXT
    FROM @getid INTO @p_sql_2
    WHILE @@FETCH_STATUS = 0
    begin
        set @p_sql = @p_sql + @p_sql_2 + ' varchar(20),'
        FETCH NEXT FROM @getid INTO @p_sql_2
    end;
    
    set @p_sql = left(@p_sql, len(@p_sql)-1) + ')';
    
    EXEC (@p_sql);
    
end;

And then just execute the procedure:

exec test_proc

You can add parameters to this to make it more usable for orher situations... Here is the demo for this second option:
