Indicates the SQL state for a given Error object.
Returns a five-character String that follows the ANSI SQL standard.
Use the SQLState property to read the five-character error code that the provider returns when an error occurs during the processing of a SQL statement. For example, when using the Microsoft ODBC Provider for OLE DB with a Microsoft® SQL Server™ database, SQL state error codes originate from ODBC based either on errors specific to ODBC or on errors that originate from Microsoft SQL Server and are then mapped to ODBC errors. These error codes are documented in the ANSI SQL standard, but may be implemented differently by different data sources.
