SqlServer将表、字段、描述等导出到EXCEL

查询SQL语句如下：

SELECT 
表名 = CASE WHEN A.COLORDER=1 THEN D.NAME ELSE '' END,
表备注 = CASE WHEN A.COLORDER=1 THEN ISNULL(F.VALUE,'') ELSE '' END,
列序号 = A.COLORDER,
列名称 = A.NAME,
标识 = CASE WHEN COLUMNPROPERTY(A.ID,A.NAME,'ISIDENTITY')=1 THEN '√ ' ELSE '' END,
主键 = 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 = A.LENGTH,
长度 = COLUMNPROPERTY(A.ID,A.NAME,'PRECISION'),
小数位 = 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,''),
列备注 = ISNULL(G.[VALUE],'')
FROM 
SYSCOLUMNS A
LEFT JOIN SYSTYPES B ON A.XUSERTYPE=B.XUSERTYPE
INNER JOIN SYSOBJECTS D ON A.ID=D.ID AND D.XTYPE='U ' --AND D.NAME<>'DTPROPERTIES'
LEFT JOIN SYSCOMMENTS E ON A.CDEFAULT=E.ID
LEFT JOIN sys.extended_properties G ON A.ID=G.major_id AND A.COLID=G.minor_id   
LEFT JOIN sys.extended_properties F ON D.ID=F.major_id AND F.minor_id=0
--where D.NAME='tbname'   --查询这个表
ORDER BY A.ID,A.COLORDER

1、在数据库(test)中添加表，这里的表名命名为 user : 并添加一些字段

2、为数据表字段添加相应的说明：这里只列出部分

3、查询表、字段、描述等内容：

查询语句：

USE test
GO

SELECT 
表名 = CASE WHEN A.COLORDER=1 THEN D.NAME ELSE '' END,
表备注 = CASE WHEN A.COLORDER=1 THEN ISNULL(F.VALUE,'') ELSE '' END,
列序号 = A.COLORDER,
列名称 = A.NAME,
标识 = CASE WHEN COLUMNPROPERTY(A.ID,A.NAME,'ISIDENTITY')=1 THEN '√ ' ELSE '' END,
主键 = 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 = A.LENGTH,
长度 = COLUMNPROPERTY(A.ID,A.NAME,'PRECISION'),
小数位 = 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,''),
列备注 = ISNULL(G.[VALUE],'')
FROM 
SYSCOLUMNS A
LEFT JOIN SYSTYPES B ON A.XUSERTYPE=B.XUSERTYPE
INNER JOIN SYSOBJECTS D ON A.ID=D.ID AND D.XTYPE='U ' --AND D.NAME<>'DTPROPERTIES'
LEFT JOIN SYSCOMMENTS E ON A.CDEFAULT=E.ID
LEFT JOIN sys.extended_properties G ON A.ID=G.major_id AND A.COLID=G.minor_id   
LEFT JOIN sys.extended_properties F ON D.ID=F.major_id AND F.minor_id=0
where D.NAME='user'   --查询这个表
ORDER BY A.ID,A.COLORDER 

查询结果：

4、将数据表字段信息导出到文件：根据第三步得到表字段详细内容。

这里你可以直接选择复制所有内容，拷贝到xls文件中 或 导出到csv文件中。
