Now I would like to replace that value in the database with a real apostrophe. I am not sure how the syntax should be to do this. I can find the ' but I am not sure how to replace. The following is the simple update I am trying to run that errors out.

更新 tblCustomer 集合Name = replace(Name, ''', ''')

update tblCustomer setName = replace(Name, ''', ''')

推荐答案

将撇号加倍以将其转义为字符串文字

Double up the apostrophe to escape it in a string literal

update tblCustomer set Name = replace(Name, ''', '''')

或者使用char函数

update tblCustomer set Name = replace(Name, ''', CHAR(39))
