如果是查询sql server 2000,把sys.extended_properties修改为SysProperties
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,
列序号 = A.COLORDER,
列名 = 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,
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],'')
