21.4.2 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. 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
