NAME

       ndb_select_all - print rows from an NDB table


SYNOPSIS

       ndb_select_all -c connect_string tbl_name -d db_name [> file_name]


DESCRIPTION

       ndb_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

       o   --lock=lock_type, -l lock_type

           Employs a lock when reading the table. Possible values for
           lock_type are:

           o   0: Read lock

           o   1: Read lock with hold

           o   2: Exclusive read lock
               There is no default value for this option.

           o   --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.

           o   --descending, -z

               Sorts the output in descending order. This option can be used
               only in conjunction with the -o (--order) option.

           o   --header=FALSE

               Excludes column headers from the output.

           o   --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.

           o   --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.

           o   --disk

               Adds a disk reference column to the output. The column is
               nonempty only for Disk Data tables having nonindexed columns.

           o   --rowid

               Adds a ROWID column providing information about the fragments
               in which rows are stored.

           o   --gci

               Adds a column to the output showing the global checkpoint at
               which each row was last updated. See Section 16.1, "MySQL
               Cluster Overview", and Section 16.5.5.2, "MySQL Cluster Log
               Events", for more information about checkpoints.

           o   --tupscan, -t

               Scan the table in the order of the tuples.

           o   --nodata

               Causes any table data to be omitted.
                     Sample Output
                   .PP 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)
               )
               TABLESPACE ts STORAGE DISK
               ENGINE=NDBCLUSTER;
               INSERT INTO dogs VALUES
                   ('', 'Lassie', 'collie'),
                   ('', 'Scooby-Doo', 'Great Dane'),
                   ('', 'Rin-Tin-Tin', 'Alsatian'),
                   ('', 'Rosscoe', 'Mutt');

           This demonstrates the use of several additional ndb_select_all
           options:

               shell> ./ndb_select_all -d ctest1 dogs -o ix -z --gci --disk
               GCI     id name          breed        DISK_REF
               834461  2  [Scooby-Doo]  [Great Dane] [ m_file_no: 0 m_page: 98 m_page_idx: 0 ]
               834878  4  [Rosscoe]     [Mutt]       [ m_file_no: 0 m_page: 98 m_page_idx: 16 ]
               834463  3  [Rin-Tin-Tin] [Alsatian]   [ m_file_no: 0 m_page: 34 m_page_idx: 0 ]
               835657  1  [Lassie]      [Collie]     [ m_file_no: 0 m_page: 66 m_page_idx: 0 ]
               4 rows returned
               NDBT_ProgramExit: 0 - OK
