BUG: Spelling Error in ADO Type Library - Schema Constraint

• ActiveX Data Objects (ADO), versions 1.5, 2.0

SYMPTOMS

The constant adSchemaReferentialConstraints is a parameter that you can pass to the OpenSchema method. In the type library it appears as adSchemaReferentialContraints. Notice the "s" is missing in "Contraints". The constant is correctly spelled "adSchemaReferentialConstraints" in the documentation.

CAUSE

The constant is misspelled in the type library.

RESOLUTION

The spelling of the constant has been fixed in MDAC 2.1

Visual Basic users are fortunate since the help of IntelliSense selects the constraint without checking the spelling of the constant.

VBScript users must misspell the constant in code (that is, adSchemaReferentialContraints) or use the numeric value 9.

For example:

   Set rs = OpenSchema( 9, criteriaArray)
   Set rs = OpenSchema(adSchemaReferentialContraints,criteriaArray) 

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

The constant adSchemaReferentialConstraints is spelled correctly in the Microsoft Developer Network (MSDN) and Data Access Software Development Kit (SDK) documentation.
