Hi, I'm trying to execute the following linq query:

Dim names As List(Of CO_NAME) = (From n As CO_NAME In model.CO_NAME Where n.COMPANY_NAME.EndsWith(str) Select n).ToList

(where str is a string variable) and I'm getting a Devart.Data.Oracle.OracleException:
"ORA-01036: illegal variable name/number"

Using DbMonitor, I see the following PREPARE line:

Code: Select all

SELECT 
1 AS C1, 
"Extent1".NAME_ID AS NAME_ID, 
"Extent1".COMPANY_NAME AS COMPANY_NAME, 
"Extent1".DO_BUS_AS_FLAG AS DO_BUS_AS_FLAG, 
"Extent1".DATE_ENDED AS DATE_ENDED, 
"Extent1".MODIFIEDBY AS MODIFIEDBY, 
"Extent1".DATEMODIFIED AS DATEMODIFIED, 
"Extent1".COMPANY_ID AS COMPANY_ID
FROM AIP.CO_NAME "Extent1"
WHERE "Extent1".COMPANY_NAME LIKE '%' || :p__linq__2

The exception is caused by the EndsWith clause. Can anyone see why this would result in that exception?

What's really weird is that if I change EndsWith to StartsWith, the query executes successfully, with the following SQL:

Code: Select all

SELECT 
1 AS C1, 
"Extent1".NAME_ID AS NAME_ID, 
"Extent1".COMPANY_NAME AS COMPANY_NAME, 
"Extent1".DO_BUS_AS_FLAG AS DO_BUS_AS_FLAG, 
"Extent1".DATE_ENDED AS DATE_ENDED, 
"Extent1".MODIFIEDBY AS MODIFIEDBY, 
"Extent1".DATEMODIFIED AS DATEMODIFIED, 
"Extent1".COMPANY_ID AS COMPANY_ID
FROM AIP.CO_NAME "Extent1"
WHERE "Extent1".COMPANY_NAME LIKE :p__linq__1 || '%'

Thanks
