Are you new to SQL REPLACE? Here’s a FREE cheat sheet for you. The article discusses 5 important points to find and replace texts in SQL using REPLACE function with examples and explanations.
Today’s code editors and word processors come with a search and replace feature. It is helpful when you need to change a word or a group of words. We don’t want to throw away our written work for a minor problem or change.
The same thing applies to our data. Users will curse us if we tell them to edit what needs to be renamed. That’s why a search and replace feature is also available to replace texts written in our databases. Here SQL REPLACE comes in.
The syntax is as follows:
<string to search>,
Note that all parameters are required. The
<original string> can be a string literal or a string result of an expression. In database tables, we usually pass a string column where we want the value to change. Meanwhile,
<string to search> is a string within
<original string> you want to search. Finally, you pass a
<replacement string> that will replace
<string to search>. Simple, enough, isn’t it?
But there can be some caveats. This way, you can avoid replacing the wrong words. Or, maybe, not replacing the right words. Then messing up your data in the end.
