This topic provides Paradox Driver-specific information. For general information about this function, see the appropriate topic under ODBC API Reference.

Attribute Comments
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.
