MySQL 5.6 Reference Manual Including MySQL NDB Cluster 7.3-7.4 Reference Guide
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. 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:
shell> ndbinfo_select_all table_name1 [table_name2] [...]
For example:
shell> ndbinfo_select_all logbuffers logspaces
