Here's the issue. My query:
UPDATE `table` SET `column` = replace(`column`,'123','456');
Is not going to work. Here's why:
The numeric string '4123' now becomes '4456'.
What I would like is for only EXACT matches (column value equals exactly '123') to be replaced. Is this not possible with a simple UPDATE SET = REPLACE() query??
Seems like you shouldn't need REPLACE to do this:
UPDATE yourTable SET yourColumn = '456' WHERE yourColumn = '123';
As Paul says, you shouldn't need a REPLACE() call, just add a suitable WHERE clause.
That said, if this is part of a bigger query updating other columns too, try this:
SET `column`=IF(`column`=123, 456, `column`)
This will only give that column a new value if it meets the condition.
