Question

This sql in code:

SELECT QHR, 
DECODE(DUCKBILLID1,NULL,' ',DUCKBILLID1) "DB1", 
DECODE(DUCKBILLID2,NULL,' ',DUCKBILLID2) "DB2", 
DECODE(DUCKBILLID3,NULL,' ',DUCKBILLID3) "DB3" 
FROM PLATYPUSSCHEDULE 
WHERE PLATYPUSID = :ABCID AND DOW = :DOW

…fails with “FROM keyword not found where expected“

The same exact thing (except that the quotes around DBN are single quotes in c# code and double quotes, AS SHOWN ABOVE, in TOAD) works just fine in TOAD.

Answer 1

In C# I’d expect to see something like

String qry = 
@"SELECT QHR,  
DECODE(DUCKBILLID1,NULL,' ',DUCKBILLID1) ""DB1"",  
DECODE(DUCKBILLID2,NULL,' ',DUCKBILLID2) ""DB2"",  
DECODE(DUCKBILLID3,NULL,' ',DUCKBILLID3) ""DB3""  
FROM PLATYPUSSCHEDULE  
WHERE PLATYPUSID = :ABCID AND DOW = :DOW";

or

String qry = 
"SELECT QHR,DECODE(DUCKBILLID1,NULL,' ',DUCKBILLID1) \"DB1\",DECODE(DUCKBILLID2,NULL,' ',DUCKBILLID2) \"DB2\",DECODE(DUCKBILLID3,NULL,' ',DUCKBILLID3) \"DB3\" FROM PLATYPUSSCHEDULE WHERE PLATYPUSID = :ABCID AND DOW = :DOW";

I certainly wouldn’t expect to see single and double quotes swapped over.
