平时看数据文档，后来想直接写些记录标记在数据库里面，每次用起来就F5一下方便多了，不用在看数据文档,所以就找了一下这样的SQL，我kao，还真有!
找了一下，不能用，改了一下，合适自己用
SELECT
表名 = CASE WHEN A.COLORDER=1 THEN D.NAME ELSE ' ' END,
表说明 = CASE WHEN A.COLORDER=1 THEN ISNULL(F.VALUE, ' ') ELSE ' ' END,
字段序号 = A.COLORDER,
字段名 = A.NAME,
标识 = CASE WHEN COLUMNPROPERTY( A.ID,A.NAME, 'ISIDENTITY ')=1 THEN '√ 'ELSE ' ' END,
主鍵 = CASE WHEN EXISTS(SELECT 1 FROM SYSOBJECTS WHERE XTYPE= 'PK ' AND PARENT_OBJ=A.ID AND NAME IN (
SELECT NAME FROM SYSINDEXES WHERE INDID IN(
SELECT INDID FROM SYSINDEXKEYS WHERE ID = A.ID AND COLID=A.COLID))) THEN '√ ' ELSE ' ' END,
类型 = B.NAME,
占用字节数 = A.LENGTH,
长度 = COLUMNPROPERTY(A.ID,A.NAME, 'PRECISION '),
小数位数 = ISNULL(COLUMNPROPERTY(A.ID,A.NAME, 'SCALE '),0),
允许空 = CASE WHEN A.ISNULLABLE=1 THEN '√ 'ELSE ' ' END,
默认值 = ISNULL(E.TEXT, ' '),
字段说明 = ISNULL(G.[VALUE], ' ')
