NDB_SELECT_ALL(1) MySQL Database System NDB_SELECT_ALL(1)NAMEndb_select_all - print rows from NDB table
SYNOPSISndb_select_all-c connect_string tbl_name -d db_name [> file_name]
DESCRIPTIONndb_select_all prints all rows from an NDB table to stdout.
Usage:
ndb_select_all-c connect_string tbl_name -d db_name [> file_name]
Additional Options:
· --lock=lock_type, -l lock_type
Employs a lock when reading the table. Possible values for lock_type
are:
· 0: Read lock
· 1: Read lock with hold
· 2: Exclusive read lock
There is no default value for this option.
· --order=index_name, -o index_name
Orders the output according to the index named index_name. Note that
this is the name of an index, not of a column, and that the index
must have been explicitly named when created.
· --descending, -z
Sorts the output in descending order. This option can be used only
in conjunction with the -o (--order) option.
· --header=FALSE
Excludes column headers from the output.
· --useHexFormat -x
Causes all numeric values to be displayed in hexadecimal format.
This does not affect the output of numerals contained in strings or
datetime values.
· --delimiter=character, -D character
Causes the character to be used as a column delimiter. Only table
data columns are separated by this delimiter.
The default delimiter is the tab character.
· --rowid
Adds a ROWID column providing information about the fragments in
which rows are stored.
· --gci
Adds a column to the output showing the global checkpoint at which
each row was last updated. See Section 14, “MySQL Cluster Glossary”,
and Section 7.3.2, “Log Events”, for more information about
checkpoints.
· --tupscan, -t
Scan the table in the order of the tuples.
· --nodata
Causes any table data to be omitted.
Sample Output:
Output from a MySQL SELECT statement:
mysql> SELECT * FROM ctest1.fish;
+----+-----------+
| id | name |
+----+-----------+
| 3 | shark |
| 6 | puffer |
| 2 | tuna |
| 4 | manta ray |
| 5 | grouper |
| 1 | guppy |
+----+-----------+
6 rows in set (0.04 sec)
Output from the equivalent invocation of ndb_select_all:
shell> ./ndb_select_all -c localhost fish -d ctest1
id name
3 [shark]
6 [puffer]
2 [tuna]
4 [manta ray]
5 [grouper]
1 [guppy]
6 rows returned
NDBT_ProgramExit: 0 - OK
Note that all string values are enclosed by square brackets (“[...]”)
in the output of ndb_select_all. For a further example, consider the
table created and populated as shown here:
CREATE TABLE dogs (
id INT(11) NOT NULL AUTO_INCREMENT,
name VARCHAR(25) NOT NULL,
breed VARCHAR(50) NOT NULL,
PRIMARY KEY pk (id),
KEY ix (name)
)
ENGINE=NDB;
INSERT INTO dogs VALUES
('', 'Lassie', 'collie'),
('', 'Scooby-Doo', 'Great Dane'),
('', 'Rin-Tin-Tin', 'German Shepherd'),
('', 'Rosscoe', 'Mutt');
This demonstrates the use of several additional ndb_select_all options:
shell> ./ndb_select_all -d ctest1 dogs -o ix -z --gci
GCI id name breed
834461 2 [Scooby-Doo] [Great Dane]
834878 4 [Rosscoe] [Mutt]
834463 3 [Rin-Tin-Tin] [German Shepherd]
835657 1 [Lassie] [Collie]
4 rows returned
NDBT_ProgramExit: 0 - OK
