You can solve this task by building a script, starting with the output from this statement: <pre><code>SELECT table_name, column_name, data_type FROM information_schema.columns WHERE table_schema = 'dbname'; ORDER BY table_name </code></pre> Details about this feature can be found here "<a href="http://dev.mysql.com/doc/refman/5.0/en/columns-table.html" rel="nofollow noreferrer">MYSQL::The INFORMATION_SCHEMA COLUMNS Table</a>" Then you can use the ALTER TABLE .. CHANGE feature to change the name of the columns e.g. <pre><code>ALTER TABLE mytable CHANGE old_name new_name varchar(5); </code></pre> See also "<a href="http://dev.mysql.com/doc/refman/5.1/en/alter-table.html" rel="nofollow noreferrer">MYSQL::ALTER TABLE Syntax</a>" Different datatype have different requirements so you need the UNIONs: <pre><code>SELECT 'ALTER TABLE '||table_name||' CHANGE '|| column_name||' '||lower(column_name)||' '||datatype||'('||CHAR(character_maximum_length)||');' AS Line FROM information_schema.columns WHERE table_schema = dbname and datatype in ( 'CHAR', 'VARCHAR' ) ORDER BY table_name UNION SELECT 'ALTER TABLE '||table_name||' CHANGE '|| column_name||' '||lower(column_name)||' '||datatype||'('||CHAR(numeric_precision)||');' AS Line FROM information_schema.columns WHERE table_schema = dbname and datatype in ( 'INTEGER' ) ORDER BY table_name UNION SELECT 'ALTER TABLE '||table_name||' CHANGE '|| column_name||' '||lower(column_name)||' '||datatype||'('||CHAR(numeric_precision)||','||CHAR(numeric_scale)|');' AS Line FROM information_schema.columns WHERE table_schema = dbname and datatype in ( 'FLOAT' ) ORDER BY table_name UNION SELECT 'ALTER TABLE '||table_name||' CHANGE '|| column_name||' '||lower(column_name)||' '||datatype||');' AS Line FROM information_schema.columns WHERE table_schema = dbname and datatype in ( 'DATE' ) ORDER BY table_name </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
