在SQL Server中，可以从INFORMATION_SCHEMA.COLUMNS中选择COLUMN_NAME。

代码如下:

SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='YourTableName'

SELECT column_name, data_type, character_maximum_length, table_name,ordinal_position, is_nullable 
FROM information_schema.COLUMNS WHERE table_name LIKE 'YOUR_TABLE_NAME'
ORDER BY ordinal_position

在SQL Server中，可以从INFORMATION_SCHEMA.COLUMNS中选择COLUMN_NAME。

代码如下:

SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='YourTableName'

SQL生成SQL:

DROP TABLE IF EXISTS test;
CREATE TABLE test (
  col001 INTEGER
, col002 INTEGER
, col003 INTEGER
, col004 INTEGER
, col005 INTEGER
, col006 INTEGER
, col007 INTEGER
, col008 INTEGER
, col009 INTEGER
, col010 INTEGER
)
;
INSERT INTO test(col001) VALUES(1);
INSERT INTO test(col002) VALUES(1);
INSERT INTO test(col005) VALUES(1);
INSERT INTO test(col009) VALUES(1);
INSERT INTO test VALUES (NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL);

SELECT
  CASE ROW_NUMBER() OVER(ORDER BY ordinal_position)
  WHEN 1 THEN 
    'SELECT'+CHAR(10)+'  *'+CHAR(10)+'FROM test'
   +CHAR(10)+'WHERE '
  ELSE
    '   OR '
  END
+ column_name +' IS NOT NULL'
+ CASE ROW_NUMBER() OVER(ORDER BY ordinal_position DESC)
  WHEN 1 THEN 
    CHAR(10)+';'
  ELSE
    ''
  END
  FROM information_schema.columns
  WHERE table_schema='dbo'
    AND table_name = 'test'
ORDER BY
  ordinal_position;

-- the whole scenario. Works for 10 , will work for 100, too:

-- out -----------------------------------------------
-- out  SELECT
-- out   *
-- out FROM test
-- out WHERE col001 IS NOT NULL
-- out     OR col002 IS NOT NULL
-- out     OR col003 IS NOT NULL
-- out     OR col004 IS NOT NULL
-- out     OR col005 IS NOT NULL
-- out     OR col006 IS NOT NULL
-- out     OR col007 IS NOT NULL
-- out     OR col008 IS NOT NULL
-- out     OR col009 IS NOT NULL
-- out     OR col010 IS NOT NULL
-- out ;

你可以试试这个。这将给出所有列名及其各自的数据类型。

desc <TABLE NAME> ;

简单，不需要sys变量:

SHOW COLUMNS FROM suppliers;
