如何使用另一个表的行值作为列名（动态）在SQL中创建新表？

Question

How do I create a new table in SQL using the row values of another table as column names? Please note the original table values are dynamic. Is dynamic Pivot the only option?

For example, if my old table looks like:

players
-----------
Lebron James
Kobe Bryant
Dwayne Wade
Chris Bosh
James Harden

I want the new table to look like:

Lebron James | Kobe Bryant | Dwayne Wade | Chris Bosh | James Harden

Answer 1

Try this example:

DROP TABLE #players 
CREATE TABLE #players (name VARCHAR(200))
INSERT INTO #players 
SELECT 'Lebron James'
UNION SELECT 'Kobe Bryant'
UNION SELECT 'Dwayne Wade'
UNION SELECT 'Chris Bosh'
UNION SELECT 'James Harden'


DECLARE @cmd VARCHAR(8000)
SET @cmd ='CREATE TABLE MyNewTable (id INT'
SELECT @cmd = @cmd + '
, ['+name+'] VARCHAR(255)'
FROM #players

SELECT @cmd = @cmd + ')'

PRINT @cmd
EXEC(@cmd)

EXEC('SELECT * FROM MyNewTable')
