How do you find the last changed tables in phpmyadmin?

When something went wrong with your website or you just want to know
which tables are recently changed you can execute the following sql
command in PhpMyAdmin:

SHOW TABLE STATUS LIKE ;

SHOW TABLE STATUS [{FROM | IN} db_name]
    [LIKE 'pattern' | WHERE expr]

SHOW TABLE STATUS works likes
SHOW TABLES, but provides a lot
of information about each non-TEMPORARY
table. You can also get this list using the mysqlshow
–status db_name
command.
The LIKE clause, if present,
indicates which table names to match. The
WHERE clause can be given to select rows
using more general conditions, as discussed in
Section 19.18, “Extensions to SHOW Statements”.

As of MySQL 5.0.1, this statement also displays information
about views.

SHOW TABLE STATUS output has the
following columns:

  • Name

    The name of the table.

  • Engine

    The storage engine for the table. See
    Chapter 14, Storage Engines.

  • Version

    The version number of the table’s .frm
    file.

  • Row_format

    The row-storage format (Fixed,
    Dynamic, Compressed,
    Redundant, Compact).
    For MyISAM tables,
    (Dynamic corresponds to what
    myisamchk -dvv reports as
    Packed. Starting with MySQL/InnoDB 5.0.3,
    the format of InnoDB tables is reported
    as Redundant or
    Compact. Prior to 5.0.3,
    InnoDB tables are always in the
    Redundant format.

  • Rows

    The number of rows. Some storage engines, such as
    MyISAM, store the exact count. For other
    storage engines, such as InnoDB, this
    value is an approximation, and may vary from the actual
    value by as much as 40 to 50%. In such cases, use
    SELECT COUNT(*) to obtain an accurate
    count.

    The Rows value is NULL
    for tables in the INFORMATION_SCHEMA
    database.

  • Avg_row_length

    The average row length.

  • Data_length

    The length of the data file.

  • Max_data_length

    The maximum length of the data file. This is the total
    number of bytes of data that can be stored in the table,
    given the data pointer size used.

  • Index_length

    The length of the index file.

  • Data_free

    The number of allocated but unused bytes.

  • Auto_increment

    The next AUTO_INCREMENT value.

  • Create_time

    When the table was created.

  • Update_time

    When the data file was last updated. For some storage
    engines, this value is NULL. For example,
    InnoDB stores multiple tables in its
    tablespace and the data file timestamp does not apply. For
    MyISAM, the data file timestamp is used;
    however, on Windows the timestamp is not updated by updates
    so the value is inaccurate.

  • Check_time

    When the table was last checked. Not all storage engines
    update this time, in which case the value is always
    NULL.

  • Collation

    The table’s character set and collation.

  • Checksum

    The live checksum value (if any).

  • Create_options

    Extra options used with CREATE
    TABLE
    . The original options supplied when
    CREATE TABLE is called are
    retained and the options reported here may differ from the
    active table settings and options.

  • Comment

    The comment used when creating the table (or information as
    to why MySQL could not access the table information).

In the table comment, InnoDB tables report
the free space of the tablespace to which the table belongs. For
a table located in the shared tablespace, this is the free space
of the shared tablespace. If you are using multiple tablespaces
and the table has its own tablespace, the free space is for only
that table. Free space means the number of completely free 1MB
extents minus a safety margin. Even if free space displays as 0,
it may be possible to insert rows as long as new extents need
not be allocated.

For MEMORY tables, the
Data_length,
Max_data_length, and
Index_length values approximate the actual
amount of allocated memory. The allocation algorithm reserves
memory in large amounts to reduce the number of allocation
operations.

Beginning with MySQL 5.0.3, for
NDBCLUSTER tables, the output of
this statement shows appropriate values for the
Avg_row_length and
Data_length columns, with the exception that
BLOB columns are not taken into
account. In addition, the number of replicas is now shown in the
Comment column (as
number_of_replicas).

For views, all the fields displayed by SHOW
TABLE STATUS
are NULL except that
Name indicates the view name and
Comment says view.
