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