hyperfilesql中的同義詞和保留的關鍵字用戶

Question

如何在HyperFileSQL中創建同義詞？

我有一張名爲USER的表格，我無法通過ODBC訪問它。我不能重命名它，所以我想爲它創建一個同義詞。我該怎麼做呢？

Answer 1

要創建同義詞，使用此功能HAlias()。

// Create an alias for the ORDERS file 
// (Syntax available from version 19) 
Orders2013 is Data Source <description=Orders> 
IF HAlias(Orders, Orders2013) = True THEN 
// ORDERS2013 can now be used in the processes 
// It behaves the same way as 
// the ORDERS file described in the analysis. 
// Modify the directory 
HChangeDir(Orders2013, "D:\SalesMgt\Archive2013") 
// Modify the name 
HChangeName(Orders2013, "Orders") 
HOpen(Orders2013) 
... 
// Processes on the Orders2013 file 
... 
END 
// Cancel the alias 
HCancelAlias(Orders)
