MYSQLSHOW(1) MySQL Database System MYSQLSHOW(1)
NAME
mysqlshow - display database, table, and column information
SYNOPSIS
mysqlshow [options] [db_name [tbl_name [col_name]]]
DESCRIPTION
The mysqlshow client can be used to quickly see which databases exist,
their tables, or a table's columns or indexes.
mysqlshow provides a command-line interface to several SQL SHOW
statements. See Section 5.4, "SHOW Syntax". The same information can be
obtained by using those statements directly. For example, you can issue
them from the mysql client program.
Invoke mysqlshow like this:
shell> mysqlshow [options] [db_name [tbl_name [col_name]]]
o If no database is given, a list of database names is shown.
o If no table is given, all matching tables in the database are shown.
o If no column is given, all matching columns and column types in the
table are shown.
The output displays only the names of those databases, tables, or
columns for which you have some privileges.
If the last argument contains shell or SQL wildcard characters ("*",
"?", "%", or "_"), only those names that are matched by the wildcard
are shown. If a database name contains any underscores, those should be
escaped with a backslash (some Unix shells require two) to get a list
of the proper tables or columns. "*" and "?" characters are converted
into SQL "%" and "_" wildcard characters. This might cause some
confusion when you try to display the columns for a table with a "_" in
the name, because in this case, mysqlshow shows you only the table
names that match the pattern. This is easily fixed by adding an extra
"%" last on the command line as a separate argument.
mysqlshow supports the following options:
