FIX: Access Violation Occurs When Querying a Remote Index Provider (269839)

SYMPTOMS

When querying a remote index provider with the Cindex OLEDB provider (OPTCIIOLEDB.dll) from Optika Inc., the following query plan generates an access violation:

|--Nested Loops(Inner Join)
|--Bookmark Lookup
| |--Index Seek
|--Bookmark Lookup
|--Index Seek

Various queries may cause the access violation. Whether or not a particular query is affected depends on the query plan that was chosen by the optimizer. Here is an example of a query that causes the error:

SELECT 
 main_1.ISSUED AS 'ISSUED',
 main_1.PCNumber AS 'PCNumber',
 main_1.CUST AS 'CUST',
 main_1.PONumber AS 'PONumber',
 main_0.SoldTO AS 'SoldTO'
FROM 
 optika..Catdata3.main AS main_0 ,
 optika..Catdata2.main AS main_1 
WHERE 
 main_1.PONumber = main_0.PONumber 
 AND main_1.PONumber = '106879'
