SQL_COLUMN_DISPLAY_SIZE

For LONGVARBINARY data, SQL_COLUMN_DISPLAY_SIZE is the maximum length of the column, not the maximum length of the column times 2.

SQL_OWNER_NAME

An empty string ("") is returned in this column because owner name is not supported.

SQL_QUALIFIER_NAME

The path to a directory is returned.

SQL_COLUMN_SEARCHABLE

LONGVARBINARY and LONGVARCHAR columns are reported as SQL_UNSEARCHABLE.

Fixed-length and variable-length binary and character data types are searchable, even though LONGVARBINARY and LONGVARCHAR are not.
