如果字段等于x，则使用mysql查询在单个表中查找和替换文本

Question

To find and replace a text in a single table the sql command is:

UPDATE `table_name`
   SET `field_name` = replace(same_field_name, 'unwanted_text', 'wanted_text')

I need to find and replace text in field_name if the filed 'language' is equal to "en-GB"

this sql doesn't work:

UPDATE `field_name` WHERE `field_name`.`language` = "it-IT"
SET `field_name` = replace(same_field_name, 'unwanted_text', 'wanted_text')

Answer 1

Your query should be like this

UPDATE Table_name SET field_name = replace(field_name, 'unwanted_text', 'wanted_text')
     WHERE language = "it-IT"
