查询数据库脚本：
SELECT name AS DbName,[dbid] As DbId,filename As FileName FROM [Master].dbo.[sysdatabases] Where dbid>4 Order by name

查询表脚本：
SELECT [{0}].dbo.sysobjects.name As TableName,id As TableId,
(Select top 1 rowcnt From [{0}].dbo.sysindexes Where id=[{0}].dbo.sysobjects.id) As RecordCount,
ISNULL(E.name,'') As PropertyName,
ISNULL(E.value,'') As PropertyValue
FROM [{0}].dbo.sysobjects
LEFT JOIN sys.extended_properties E ON E.major_id=[{0}].dbo.sysobjects.id AND E.minor_id=0
Where xtype='U' AND [{0}].dbo.sysobjects.name not in ('dtproperties','sysdiagrams') Order By [{0}].dbo.sysobjects.name

查询数据库对象脚本：
SELECT T.name As ObjectName,T.id As ObjectId,rTRIM(T.xtype) AS ObjectType,
(SELECT Top 1 A.[definition] FROM [{0}].sys.sql_modules A JOIN [{0}].sys.objects B ON A.object_id = B.object_id
Where B.name=T.name) As ObjectDefinition
FROM [{0}].dbo.sysobjects T
Where xtype in ( N'P', N'PC',N'FN', N'IF', N'TF', N'FS', N'FT', N'V',N'TR')
AND T.name not in ('dtproperties','sysdiagrams')
Order By T.name

查询列与字段：
Select
C.name As TableName,
C.id As TableObjectId,
A.name As ColumnName,
A.colid As ColumnObjectId,
A.[length] As ColumnLength,
B.name As ColumnDataType,
ISNULL(D.[text],'') AS DefaultValue,
ISNULL(E.name,'') As PropertyName,
ISNULL(E.value,'') As PropertyValue,
COLUMNPROPERTY(A.id,A.name, 'AllowsNULL') AS AllowsNull,
COLUMNPROPERTY(A.id,A.name, 'IsCursorType') AS IsCursorType,
COLUMNPROPERTY(A.id,A.name, 'IsIdentity') AS IsIdentity,
(Select Count(1) From
sysobjects
INNER JOIN sysindexes ON sysobjects.parent_obj=sysindexes.id AND sysobjects.name=sysindexes.name
INNER JOIN sysindexkeys ON sysindexes.id=sysindexkeys.id AND sysindexes.indid=sysindexkeys.indid
Where sysobjects.xtype='PK' AND sysobjects.parent_obj=A.id AND sysindexkeys.colid=A.colid) AS IsPrimaryKey
From
dbo.syscolumns A
INNER JOIN dbo.systypes B ON B.xusertype=A.xtype
INNER JOIN dbo.sysobjects C ON C.id=A.id AND C.xtype IN ('U','V') AND C.name not in ('dtproperties','sysdiagrams')
LEFT JOIN dbo.syscomments D ON A.cdefault = D.id
LEFT JOIN sys.extended_properties E ON E.major_id=A.id AND E.minor_id=A.colid order by A.colid

查询约束脚本：
SELECT
b.rkeyid AS MasterTableObjectId,
object_name(b.rkeyid) AS MasterTableName,
b.rkey As MasterColumnObjectId,
(SELECT name FROM syscolumns WHERE colid=b.rkey AND id=b.rkeyid) AS MasterColumnName,
b.fkeyid AS ForeignTableObjectId,
object_name(b.fkeyid) AS ForeignTableName,
b.fkey AS ForeignColumnObjectId,
(SELECT name FROM syscolumns WHERE colid=b.fkey AND id=b.fkeyid) As ForeignColumnName,
ObjectProperty(a.id,'CnstIsUpdateCascade') AS UpdateCascade,
ObjectProperty(a.id,'CnstIsDeleteCascade') AS DeleteCascade
FROM sysobjects a
join sysforeignkeys b on a.id=b.constid
join sysobjects c on a.parent_obj=c.id
WHERE a.xtype='F' AND c.xtype='U'
