三條 SQL 視圖搞定所有 SQL Server 資料庫字典文檔生成

編輯：關於SqlServer

一、表結構字典

SELECT TOP 100 PERCENT
    CASE WHEN a.colorder = 1 THEN d.name ELSE '' END AS 表名,
    CASE WHEN a.colorder = 1 THEN ISNULL(f.value, '') ELSE '' END AS 表說明,
    a.colorder AS 字段序號,
    a.name AS 字段名,
    CASE WHEN COLUMNPROPERTY(a.id, a.name, 'IsIdentity') = 1 THEN '√' ELSE '' END AS 標識,
    CASE WHEN EXISTS (
        SELECT 1 FROM dbo.sysindexes si
        JOIN dbo.sysindexkeys sik ON si.id = sik.id AND si.indid = sik.indid
        JOIN dbo.syscolumns sc ON sc.id = sik.id AND sc.colid = sik.colid
        JOIN dbo.sysobjects so ON so.name = si.name AND so.xtype = 'PK'
        WHERE sc.id = a.id AND sc.colid = a.colid
    ) THEN '√' ELSE '' END AS 主鍵,
    b.name AS 類型,
    a.length AS 長度,
    COLUMNPROPERTY(a.id, a.name, 'PRECISION') AS 精度,
    ISNULL(COLUMNPROPERTY(a.id, a.name, 'Scale'), 0) AS 小數位數,
    CASE WHEN a.isnullable = 1 THEN '√' ELSE '' END AS 允許空,
    ISNULL(e.text, '') AS 預設值,
    ISNULL(g.[value], '') AS 字段說明,
    d.crdate AS 建立時間,
    CASE WHEN a.colorder = 1 THEN d.refdate ELSE NULL END AS 修改時間
FROM dbo.syscolumns a
LEFT JOIN dbo.systypes b ON a.xtype = b.xusertype
INNER JOIN dbo.sysobjects d ON a.id = d.id AND d.xtype = 'U' AND d.status >= 0
LEFT JOIN dbo.syscomments e ON a.cdefault = e.id
LEFT JOIN dbo.sysproperties g ON a.id = g.id AND a.colid = g.smallid
LEFT JOIN dbo.sysproperties f ON d.id = f.id AND f.smallid = 0
ORDER BY d.name, a.colorder;

二、索引字典

SELECT TOP 100 PERCENT
    CASE WHEN b.keyno = 1 THEN c.name ELSE '' END AS 表名,
    CASE WHEN b.keyno = 1 THEN a.name ELSE '' END AS 索引名稱,
    d.name AS 列名,
    b.keyno AS 索引順序,
    CASE INDEXKEY_PROPERTY(c.id, b.indid, b.keyno, 'isdescending')
        WHEN 1 THEN '降序' WHEN 0 THEN '升序' END AS 排序,
    CASE WHEN p.id IS NULL THEN '' ELSE '√' END AS 主鍵,
    CASE INDEXPROPERTY(c.id, a.name, 'IsClustered')
        WHEN 1 THEN '√' WHEN 0 THEN '' END AS 聚集,
    CASE INDEXPROPERTY(c.id, a.name, 'IsUnique')
        WHEN 1 THEN '√' WHEN 0 THEN '' END AS 唯一,
    CASE WHEN e.id IS NULL THEN '' ELSE '√' END AS 唯一約束,
    a.OrigFillFactor AS 填充因子,
    c.crdate AS 建立時間,
    c.refdate AS 修改時間
FROM dbo.sysindexes a
JOIN dbo.sysindexkeys b ON a.id = b.id AND a.indid = b.indid
JOIN dbo.syscolumns d ON b.id = d.id AND b.colid = d.colid
JOIN dbo.sysobjects c ON a.id = c.id AND c.xtype = 'U'
LEFT JOIN dbo.sysobjects e ON e.name = a.name AND e.xtype = 'UQ'
LEFT JOIN dbo.sysobjects p ON p.name = a.name AND p.xtype = 'PK'
WHERE OBJECTPROPERTY(a.id, N'IsUserTable') = 1
  AND OBJECTPROPERTY(a.id, N'IsMSShipped') = 0
  AND INDEXPROPERTY(a.id, a.name, 'IsAutoStatistics') = 0
ORDER BY c.name, a.name, b.keyno;

三、主鍵/外鍵/約束/視圖/函數/預存程序/觸發器綜合字典

SELECT DISTINCT TOP 100 PERCENT
    o.xtype,
    CASE o.xtype
        WHEN 'X' THEN '擴展預存程序'
        WHEN 'TR' THEN '觸發器'
        WHEN 'PK' THEN '主鍵'
        WHEN 'F' THEN '外鍵'
        WHEN 'C' THEN '約束'
        WHEN 'V' THEN '視圖'
        WHEN 'FN' THEN '函數-標量'
        WHEN 'IF' THEN '函數-內嵌'
        WHEN 'TF' THEN '函數-表值'
        ELSE '預存程序'
    END AS 類型,
    o.name AS 對象名,
    o.crdate AS 建立時間,
    o.refdate AS 修改時間,
    c.text AS 宣告語句
FROM dbo.sysobjects o
LEFT JOIN dbo.syscomments c ON o.id = c.id
WHERE o.xtype IN ('X','TR','C','V','F','IF','TF','FN','P','PK')
  AND OBJECTPROPERTY(o.id, N'IsMSShipped') = 0
ORDER BY
    CASE o.xtype
        WHEN 'X' THEN '擴展預存程序'
        WHEN 'TR' THEN '觸發器'
        WHEN 'PK' THEN '主鍵'
        WHEN 'F' THEN '外鍵'
        WHEN 'C' THEN '約束'
        WHEN 'V' THEN '視圖'
        WHEN 'FN' THEN '函數-標量'
        WHEN 'IF' THEN '函數-內嵌'
        WHEN 'TF' THEN '函數-表值'
        ELSE '預存程序'
    END DESC;
