Query to find and replace text in all tables and fields of a mysql db
You need to use the information_schema database to generate the script.

Collect all columns from every table of every database that have the following criteria:


Exclude the following databases:


information_schema
performance_schema
mysql

COLUMN_TYPE values with one of the following characteristics:


starts with CHAR(
starts with VARCHAR(
ends with TEXT (TEXT, MEDIUMTEXT, LONGTEXT)



Here is the query to get those columns

SELECT table_schema,table_name,column_name FROM information_schema.columns
WHERE table_schema NOT IN ('information_schema','mysql','performance_schema')
AND (column_type LIKE 'char(%' OR column_type LIKE 'varchar(%' OR column_type LIKE '%text');


Using the above query, construct a set of queries that outputs SQL for converting fuschia to fuchsia:

SELECT CONCAT('UPDATE ',table_schema,'.',table_name,
' SET ',column_name,'=REPLACE(',column_name,',''fuschia'',''fuchsia'');')
FROM information_schema.columns
WHERE table_schema NOT IN ('information_schema','mysql','performance_schema')
AND (column_type LIKE 'char(%'
OR column_type LIKE 'varchar(%'
OR column_type LIKE '%text');


Take that query and send its output to a text file. Import text into mysql:

SQL="SELECT CONCAT('UPDATE ',table_schema,'.',table_name,"
SQL="${SQL}' SET \`',column_name,'\`=REPLACE(\`',column_name,'\`,''fuschia'',''fuchsia'');') "
SQL="${SQL} FROM information_schema.columns WHERE "
SQL="${SQL} table_schema NOT IN ('information_schema','mysql','performance_schema') "
SQL="${SQL} AND (column_type LIKE 'char(%' "
SQL="${SQL} OR column_type LIKE 'varchar(%'"
SQL="${SQL} OR column_type LIKE '%text');"
mysql -u... -p... -ANe"${SQL}" &gt; GlobalReplace_fuschia_to_fuchsia.sql
less GlobalReplace_fuschia_to_fuchsia.sql


If the file looks good, feel free to execute it.

Give it a Try !!!
