Wildcards now support escaped chars and underscore matching (needed to link tables with underscores in access).

Made distinction between CHAR/BINARY (and VAR versions).

Fixed display size to be length if max length isn’t available.

Also made SQL_DESC_NAME only fill in the name if there was a data pointer given, otherwise just the length.

Fixed string length to chars, not bytes, returned by SQLGetDiagRec.

Fix size return from SQLDescribeCol.

Fixed type returned for MYSQL_TYPE_LONG to SQL_INTEGER instead of SQL_TINYINT.

Fixed handling of numeric pointers in SQLColAttribute.

Updated retrieval of descriptor fields to use the right pointer types.

Length now used when handling bind parameter (needed in particular for SQL_WCHAR) - this enables updating char data in MS Access.

Allow SQLDescribeCol to be called to retrieve the length of the column name, but not the name itself.

Fixed MDiagnostic to use correct v2/v3 error codes.

Set default return to SQL_SUCCESS if nothing is done for SQLSpecialColumns.

Fixed using wrong pointer for SQL_MAX_DRIVER_CONNECTIONS in SQLGetInfo.

Fixed binding using SQL_C_LONG.
