SYMPTOMS

Consider the following scenario. On an instance of Microsoft SQL Server 2005, you install Cumulative Update 6 for SQL Server 2005 Service Pack 2 (SP2). You create a table that contains a binary type column, such as an image column. You have an application that uses the SQL Native client ODBC driver to connect to the instance of SQL Server. In the application, you use the SQLGetData function to retrieve the data of the column. In this scenario, the function may return zero for the actual size of the data that is to be copied. This problem occurs when the following conditions are true:
  • You specify the TargetType parameter of the SQLGetData function as SQL_C_CHAR or as SQL_C_WCHAR.
  • You specify the BufferLength parameter of the SQLGetData function as 0.
For example, this issue occurs when you use the Osql.exe utility to retrieve data from an image column.

CAUSE

The SQLGetData function lets an application query the size of the data that is to be copied before the application provides a buffer to copy the data. This problem occurs when a user requests the data size of a binary type column by using a buffer size of 0 specified in the SQLGetData function. The function incorrectly returns zero instead of returning the actual size of the data that is to be copied.

Important information for SQL Server 2005 Analysis Services

A known issue exists in Cumulative Update 7 for SQL Server 2005 Analysis Services. Consider the following scenario. You install Cumulative Update 7 for SQL Server 2005 SP2. In SQL Server Profiler, you start a trace or stop a trace. Then, you run a query. The execution time of the query exceeds the value of the ForceCommitTimeout server setting. In this scenario, all the queries that are running on the server are canceled. To work around this issue, do not run MDX queries before you start a trace or stop a trace.
