如何在Oracle中写IIF条件

Question

我们如何在 Oracle 中编写 IIF 条件。

IIF(ItemType = '-1' , (Select CAST(CAST(ConfigXml as XML).query('data(/configurations/config/itemtypeid)') as nvarchar (64)) from EmailCaptureConfig where OwnerID = 142 and ConfigID = 1), ActionObjecttype) as ActionObject

我需要将上面的 IIF 转换成 ORACLE 但我做不到。我们如何推进这件事。

Answer 1

与此类似：

decode(ItemType, '-1' , (Select CAST(CAST(ConfigXml as XML).query('data(/configurations/config/itemtypeid)') as nvarchar (64)) from EmailCaptureConfig where OwnerID = 142 and ConfigID = 1), ActionObjecttype) as ActionObject

显然 xml 数据类型在 Oracle 中的工作方式与 Microsoft 不同。
