sql - 带有 UniVerse ODBC 驱动程序的标量函数

Question

我正在使用 UniVerse ODBC 驱动程序将数据从我们的事务系统提取到 SQL Server 2008。ODBC 驱动程序安装在 Windows Server 2003 上并且工作正常。我试图在编写标量函数（如 CONVERT）的语法上找到一些帮助。

当我浏览手册时，我发现该功能是受支持的。但是当我尝试写一个查询时

SELECT CONVERT(ID AS VARCHAR(10)) FROM TableName

查询因语法错误而失败。我怀疑 ODBC 驱动程序不支持这种语法。对此的任何帮助将不胜感激。谢谢。

You will need to format your scalar functions like so:

{fn CONVERT(EXAMPLEFIELD, SQL_VARCHAR )}

Therefore, your completed query may look like:

SELECT {fn CONVERT(ID, SQL_VARCHAR )} FROM TableName

I tested a similar query through my ODBC connection to Universe and it did not result in a syntax error.

I found the following article from Microsoft about ODBC explicit conversions to be helpful: http://msdn.microsoft.com/en-us/library/windows/desktop/ms715381(v=vs.85).aspx
