📝 Title: How to Escape Double Quotes in XML Attributes in T-SQL

👋 Hey there, fellow SQL enthusiast! Do you often face the challenge of dealing with double quotes in XML attributes in T-SQL? Fear not, because today we're going to explore this common issue and provide you with easy solutions to escape those pesky quotes. By the end of this blog post, you'll be equipped with the knowledge to tackle this problem with confidence. Let's dive in!

Identifying the Issue

🔎 Our questioner encountered a problem where they wanted to include double quotes within an XML attribute but couldn't figure out how to escape them correctly. They had tried various approaches such as \", "", and \\", with no success.

💡 The challenge here lies in correctly formatting the XML data within a T-SQL script while considering the special characters present in the attribute value. So how do we overcome this hurdle? Let's find out!

Solution 1: Using "

💡 One approach to escaping double quotes in XML attributes is to replace each double quote with the entity reference ". This entity reference represents a double quote character in XML. Let's see how it works in our scenario:

declare @xml xml
set @xml = '<transaction><item value="hi "mom" lol" 
    ItemId="106"  ItemType="2"  instanceId="215923801"  dataSetId="1" /></transaction>'

-- Rest of the code...

🔧 In the code snippet above, we substituted the inner double quotes in the value attribute with the " entity reference. This ensures proper parsing and interpretation of the XML attribute containing double quotes.

Solution 2: Using single quotes

💡 Another approach to tackle this issue is to use single quotes (') instead of double quotes ("). By wrapping the XML attribute value within single quotes, we eliminate the need to escape any double quotes. Take a look:

declare @xml xml
set @xml = '<transaction><item value=''hi "mom" lol'' 
    ItemId="106"  ItemType="2"  instanceId="215923801"  dataSetId="1" /></transaction>'

-- Rest of the code...

🔧 In the modified code snippet, we replaced the double quotes around the attribute value with single quotes. This simple adjustment ensures the value is correctly interpreted as part of the XML structure.
