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. |
