Oracle长动态查询及其调试方法
原标题:Long dynamic Oracle query and How to debug it

我有一个存储过程,我目前正在处理它,它使用动态sql查询。

It has one variable assigned to (5000 - 6000 characters of dynamic SQL) and another variable assigned to (5000 - 6000 characters of dynamic SQL) and a UNION ALL between both the variables.

我从过程中获得了动态查询,并在编辑器上运行它。它给我返回了一行数据。如何调试此查询?

我可以:

var1 = "dyamic SQL..." 
UNION ALL 
var2 = "dynamic SQL..."

任何帮助我调试的建议都将不胜感激。

最佳回答

您可以运行动态查询(如果这是一个术语的话),但不能以这种方式运行。您可以使用执行查询字符串

EXECUTE IMMEDIATE  sqlstring 

或使用

OPEN c FOR  sqlstring 

还有一个包可以让您使用绑定参数执行查询。

但所有这些都要求查询是单个字符串,所以我建议您将这两个查询放在第三个变量中。。。

var3 = var1 ||   UNION ALL   || var2;

..,然后执行var3。
