Export SQL Server Schema

本文主要是介绍Export SQL Server Schema，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

EF没有将display name属性设置到数据库表属性的功能，只能用SQL自己设置

Column Description

    EXEC sp_addextendedproperty 
    @name = N'MS_Description', @value = 'Hey, here is my description!',
    @level0type = N'Schema',   @level0name = 'dbo',
    @level1type = N'Table',    @level1name = 'AppTestClasses',
    @level2type = N'Column',   @level2name = 'Description';

Query Schema

SELECT
    IC.TABLE_NAME,
    IC.COLUMN_NAME,
    IC.Data_TYPE,
    EP.[Value] as [MS_Description],
    --IKU.CONSTRAINT_NAME, 
    --ITC.CONSTRAINT_TYPE,
    IC.IS_NULLABLE
 FROM
    INFORMATION_SCHEMA.COLUMNS IC
    INNER JOIN sys.columns sc ON OBJECT_ID(QUOTENAME(IC.TABLE_SCHEMA) + '.' + QUOTENAME(IC.TABLE_NAME)) = sc.[object_id] AND IC.COLUMN_NAME = sc.name
    LEFT OUTER JOIN sys.extended_properties EP ON sc.[object_id] = EP.major_id AND sc.[column_id] = EP.minor_id AND EP.name = 'MS_Description' AND EP.class = 1 
    LEFT OUTER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE IKU ON IKU.COLUMN_NAME = IC.COLUMN_NAME and IKU.TABLE_NAME = IC.TABLE_NAME and IKU.TABLE_CATALOG = IC.TABLE_CATALOG
    LEFT OUTER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS ITC ON ITC.TABLE_NAME = IKU.TABLE_NAME and ITC.CONSTRAINT_NAME = IKU.CONSTRAINT_NAME
WHERE IC.TABLE_CATALOG = 'DRS'
  and IC.TABLE_SCHEMA = 'dbo'
  --and IC.TABLE_NAME = 'Table'
order by IC.TABLE_NAME,
    IC.COLUMN_NAME
