如何获取外键约束中涉及的引用表名称

Question

我的数据库中有一个外键，如：

ViewPager

所以写了一个小的c＃程序来从我的数据库中获取CONSTRAINT [FK_Table1_Table2] FOREIGN KEY (Id) REFERENCES [Table2]([Id]) ：

ForeignKeys

这将返回外键在using (SqlConnection connection = new SqlConnection(connectionString.ConnectionString)) { connection.Open(); DataTable getSchema = connection.GetSchema("Tables"); foreach (DataRow tableRow in getSchema.Rows) { String tableName = tableRow.Field<String>("TABLE_NAME"); DataTable fKeys = connection.GetSchema("ForeignKeys", new[] { database, "dbo", tableName }); foreach (DataRow keys in fKeys.Rows) { String tName = key.Field<String>("table_name"); } } } 上的Table的名称，但我无法获得该外键引用(Table1)的其他表的其他名称。

是否可以使用c＃？

获取外键约束中另一个表的名称

答案（由于标记为重复而在此处发布）

(Table2)

然后，您可以使用以下内容对表格进行过滤：

using (SqlConnection connection = new SqlConnection(connectionString.ConnectionString))
{
     connection.Open();
     DataTable foreignKeys = new DataTable();
     using (SqlCommand command = new SqlCommand("SELECT OBJECT_NAME(f.parent_object_id) ConsTable, OBJECT_NAME(f.referenced_object_id) refTable, COL_NAME(fc.parent_object_id, fc.parent_column_id) ColName FROM sys.foreign_keys AS f INNER JOIN sys.foreign_key_columns AS fc ON f.OBJECT_ID = fc.constraint_object_id INNER JOIN sys.tables t ON t.OBJECT_ID = fc.referenced_object_id order by ConsTable",connection))
     {
         using (SqlDataAdapter dataAdaptor = new SqlDataAdapter(command))
         {
              dataAdaptor.Fill(foreignKeys);
         }
     }
}
