Question

在Sql Server 2005中，我有一个主表，以及其他几个与之相关的表这个高手通过几个一对多的关系。如何找到与之相关的所有表格和字段主表中的主键，在“很多”方面？

我知道我可以通过查询INFORMATION_SCHEMA中的视图来提取它，但我不知道到底能找到这个信息。

谢谢

Answer 1

退房：

INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE INFORMATION_SCHEMA.CONSTRAINT_TABLE_USAGE

Answer 2

我在sql server组上找到了一些帮助我使用以下查询，它在关系的一个和多个方面返回模式名称，表和字段名称：

SELECT
    SchemaParent.name AS ParentSchemaName, 
    TableParent.name AS ParentTableName, 
    ColumnParent.name AS ParentColumnName, 
    SchemaChild.name AS ChildSchemaName, 
    TableChild.name AS ChildTableName, 
    ColumnChild.name AS ChildColumnName
FROM         
    sys.foreign_key_columns AS kc INNER JOIN
        sys.objects AS TableChild ON kc.parent_object_id = TableChild.object_id INNER JOIN
        sys.schemas AS SchemaChild ON TableChild.schema_id = SchemaChild.schema_id INNER JOIN
        sys.objects AS TableParent ON kc.referenced_object_id = TableParent.object_id INNER JOIN
        sys.schemas AS SchemaParent ON TableParent.schema_id = SchemaParent.schema_id INNER JOIN
        sys.columns AS ColumnParent ON kc.referenced_object_id = ColumnParent.object_id AND kc.referenced_column_id = ColumnParent.column_id INNER JOIN
        sys.columns AS ColumnChild ON kc.parent_object_id = ColumnChild.object_id AND kc.parent_column_id = ColumnChild.column_id
ORDER BY ParentTableName, ChildTableName

查找与某个表的关系“很多”方面的所有表和字段
