ndb_select_all -c connect_string tbl_name -d db_name [> file_name]
Employs a lock when reading the table. Possible values for lock_type are:
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.
Sorts the output in descending order. This option can be used only in conjunction with the -o (--order) option.
Excludes column headers from the output.
Causes all numeric values to be displayed in hexadecimal format. This does not affect the output of numerals contained in strings or datetime values.
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.
Adds a ROWID column providing information about the fragments in which rows are stored.
Adds a column to the output showing the global checkpoint at which each row was last updated. See Section 12, "MySQL Cluster Glossary", and Section 6.3.2, "Log Events", for more information about checkpoints.
Scan the table in the order of the tuples.
Causes any table data to be omitted.
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
