SYMPTOMS
The Microsoft ODBC .NET managed provider always binds a decimal or numeric data type value with a precision of 28. Even if you manually set the precision of a decimal or numeric parameter to something other than 28, the ODBC .NET managed provider changes it back to 28.

Some third-party drivers (for example: Oracle RDB ODBC Driver) may not support a decimal or numeric data type value with a precision of 28. When you use these third-party drivers to pass decimal or numeric parameters, you may receive the following error message:

DIAG [HY104] [Oracle][ODBC]Invalid precision or scale value. (0)

DIAG [HY021] [Oracle][ODBC]Inconsistent descriptor information. (0)



MORE INFORMATION
With this current fix, the ODBC .NET managed provider does the following:
 * 1) If the user specifies a precision, the ODBC .NET managed provider takes the lesser value of the returned precision, and the URT type decimal value with a precision of 28.
 * 2) If the user does not specify a precision, the .NET ODBC managed provider calls SQLGetTypeInfo with SQL_DECIMAL to get the maximum precision that is supported for the data type.
