Question

I’m trying to remove all occurences of ` in TRIGGER_NAME and replace them with ‘

UPDATE Scheduler.dbo.QRTZ_BLOB_TRIGGERS
SET TRIGGER_NAME = REPLACE(TRIGGER_NAME, '`', '\\'')
WHERE
TRIGGER_NAME LIKE '%`%';

The logic I’m following is that I need to escape \’ to show it but also save it escaped?

Answer 1

You usually only need a single backslash, ie

REPLACE(TRIGGER_NAME, '`', '\'')

You can also use a double single-quote which is more standard across database vendors

REPLACE(TRIGGER_NAME, '`', '''')
