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'
