MySQL 8.4 Reference Manual  /  ...  /  ndbinfo_select_all — Select From ndbinfo Tables

25.5.2 ndbinfo_select_all — Select From ndbinfo Tables

ndbinfo_select_all is a client program that selects all rows and columns from one or more tables in the ndbinfo database

Not all ndbinfo tables available in the mysql client can be read by this program (see later in this section). In addition, ndbinfo_select_all can show information about some tables internal to ndbinfo which cannot be accessed using SQL, including the tables and columns metadata tables.

To select from one or more ndbinfo tables using ndbinfo_select_all, it is necessary to supply the names of the tables when invoking the program as shown here:

$> ndbinfo_select_all table_name1  [table_name2] [...]

For example:

$> ndbinfo_select_all logbuffers logspaces
== logbuffers ==
node_id log_type        log_id  log_part        total   used    high
