I've just upgraded to SQL Anywhere v16 using ADO.NET. Now, when loading a set of records with a long nvarchar column in, some of the strings are truncated to 65535 in length when retrieved in my .NET app. This is a definite bug in the iAnywhere.Data.SQLAnywhere DLL because if I revert to using v12, this problem goes away. To reproduce, just create a table with a long nvarchar column. Populate some rows (at least 6) with data longer than 65535. Then, using ADO.NET, use an SACommand and SADataReader to retrieve the long varchar column and inspect the length of each. Thanks Simon |

UPDATE: This issue is now resolved in CR #742857, in builds 11.0.1.3013, 12.0.1.3937, 16.0.0.1602. I have now been able to reproduce this issue and have opened CR #742857 to address this problem in a future EBF of SQL Anywhere. Thank you for the bug report. |
This sounds similar to the issues reported in this question... http://sqlanywhere-forum.sap.com/questions/16506/string-truncation-bug-in-ianywheredatasqlanywherev40dll
