Sql Server查询表结构和索引信息

以下两段语句分别是获取表的基本结构和获取表对应的索引信息，直接复制到查询分析器中就可以使用，在每个的最下面有一个输入表名的地方，若不输入则代表查询全部的表。

1.表结构信息查询 表结构信息查询

SELECT     TableName=CASE WHEN C.column_id=1 THEN O.name ELSE N'' END,    TableDesc=ISNULL(CASE WHEN C.column_id=1 THEN PTB.[value] END,N''),    Column_id=C.column_id,    ColumnName=C.name,    PrimaryKey=ISNULL(IDX.PrimaryKey,N''),    [IDENTITY]=CASE WHEN C.is_identity=1 THEN N'√'ELSE N'' END,    Computed=CASE WHEN C.is_computed=1 THEN N'√'ELSE N'' END,    Type=T.name,    Length=C.max_length,    Precision=C.precision,    Scale=C.scale,    NullAble=CASE WHEN C.is_nullable=1 THEN N'√'ELSE N'' END,    [Default]=ISNULL(D.definition,N''),    ColumnDesc=ISNULL(PFD.[value],N''),    IndexName=ISNULL(IDX.IndexName,N''),    IndexSort=ISNULL(IDX.Sort,N''),    Create_Date=O.Create_Date,    Modify_Date=O.Modify_dateFROM sys.columns C    INNER JOIN sys.objects O        ON C.[object_id]=O.[object_id]            AND O.type='U'            AND O.is_ms_shipped=0    INNER JOIN sys.types T        ON C.user_type_id=T.user_type_id    LEFT JOIN sys.default_constraints D        ON C.[object_id]=D.parent_object_id            AND C.column_id=D.parent_column_id            AND C.default_object_id=D.[object_id]    LEFT JOIN sys.extended_properties PFD        ON PFD.class=1             AND C.[object_id]=PFD.major_id             AND C.column_id=PFD.minor_id--             AND PFD.name='Caption'  -- 字段说明对应的描述名称(一个字段可以添加多个不同name的描述)    LEFT JOIN sys.extended_properties PTB        ON PTB.class=1             AND PTB.minor_id=0             AND C.[object_id]=PTB.major_id--             AND PFD.name='Caption'  -- 表说明对应的描述名称(一个表可以添加多个不同name的描述)  LEFT JOIN                       -- 索引及主键信息    (        SELECT             IDXC.[object_id],            IDXC.column_id,            Sort=CASE INDEXKEY_PROPERTY(IDXC.[object_id],IDXC.index_id,IDXC.index_column_id,'IsDescending')                WHEN 1 THEN 'DESC' WHEN 0 THEN 'ASC' ELSE '' END,            PrimaryKey=CASE WHEN IDX.is_primary_key=1 THEN N'√'ELSE N'' END,            IndexName=IDX.Name        FROM sys.indexes IDX        INNER JOIN sys.index_columns IDXC            ON IDX.[object_id]=IDXC.[object_id]                AND IDX.index_id=IDXC.index_id        LEFT JOIN sys.key_constraints KC            ON IDX.[object_id]=KC.[parent_object_id]                AND IDX.index_id=KC.unique_index_id        INNER JOIN  -- 对于一个列包含多个索引的情况,只显示第1个索引信息        (            SELECT [object_id], Column_id, index_id=MIN(index_id)            FROM sys.index_columns            GROUP BY [object_id], Column_id        ) IDXCUQ            ON IDXC.[object_id]=IDXCUQ.[object_id]                AND IDXC.Column_id=IDXCUQ.Column_id                AND IDXC.index_id=IDXCUQ.index_id    ) IDX        ON C.[object_id]=IDX.[object_id]            AND C.column_id=IDX.column_id-- WHERE O.name=N'Permissions'       -- 如果只查询指定表,加上此条件ORDER BY O.name,C.column_id

2. 索引及主键信息

SELECT     TableId=O.[object_id],    TableName=O.Name,    IndexId=ISNULL(KC.[object_id],IDX.index_id),    IndexName=IDX.Name,    IndexType=ISNULL(KC.type_desc,'Index'),    Index_Column_id=IDXC.index_column_id,    ColumnID=C.Column_id,    ColumnName=C.Name,    Sort=CASE INDEXKEY_PROPERTY(IDXC.[object_id],IDXC.index_id,IDXC.index_column_id,'IsDescending')        WHEN 1 THEN 'DESC' WHEN 0 THEN 'ASC' ELSE '' END,    PrimaryKey=CASE WHEN IDX.is_primary_key=1 THEN N'√'ELSE N'' END,    [UQIQUE]=CASE WHEN IDX.is_unique=1 THEN N'√'ELSE N'' END,    Ignore_dup_key=CASE WHEN IDX.ignore_dup_key=1 THEN N'√'ELSE N'' END,    Disabled=CASE WHEN IDX.is_disabled=1 THEN N'√'ELSE N'' END,    Fill_factor=IDX.fill_factor,    Padded=CASE WHEN IDX.is_padded=1 THEN N'√'ELSE N'' ENDFROM sys.indexes IDX    INNER JOIN sys.index_columns IDXC        ON IDX.[object_id]=IDXC.[object_id]            AND IDX.index_id=IDXC.index_id    LEFT JOIN sys.key_constraints KC        ON IDX.[object_id]=KC.[parent_object_id]            AND IDX.index_id=KC.unique_index_id    INNER JOIN sys.objects O        ON O.[object_id]=IDX.[object_id]    INNER JOIN sys.columns C        ON O.[object_id]=C.[object_id]            AND O.type='U'            AND O.is_ms_shipped=0            AND IDXC.Column_id=C.Column_id    INNER JOIN  -- 对于一个列包含多个索引的情况,只显示第1个索引信息    (        SELECT [object_id], Column_id, index_id=MIN(index_id)        FROM sys.index_columns        GROUP BY [object_id], Column_id    ) IDXCUQ        ON IDXC.[object_id]=IDXCUQ.[object_id]            AND IDXC.Column_id=IDXCUQ.Column_id--where o.object_id=object_id('表名')
