| I have 1000 SQL rows that contain a column with data type LONGTEXT. Each of these columns contains an incorrect phone number somewhere within the column. I have tried the code below to update the phone number. UPDATE table SET text = replace('514-921-2738', '514-921-2738', '514-234-0315')However, instead of simply replacing the first phone number - 514-921-2738 - with the second phone number - 514-234-0315, it replaces the entire text block with the second phone number. In other words, all that remains after I run the code is the phone number. Clearly, I am not fully understanding how to use the REPLACE function but after looking at the online documentation, I don't see what I am doing wrong. Any thoughts? |
