How to replace a single quote with double quotes in ADF dynamic expressions

Question

I am trying to replace single quote in a string with double quote using replace function with data factory expressions.

For example, replace single quote in the following string

hello'world ---> hello''world

@replace(pipeline().parameters.tst,''','''')

The above code is not working. Need help in fixing the code

You can declare a new parameter with the value ' (single quote). You can look at the following demonstration for reference.

I have taken 2 parameters, text with the value hello'world and replace_char with the value '.

I used a set variable activity to store the output of the replace() function (for demonstration) into variable named output (String). Now, I modified the value as:

@replace(pipeline().parameters.text,pipeline().parameters.replace_char,'"')

This successfully helps in replacing a single quote with double quote character.

NOTE: The \ in the output variable value indicates that the " is to be considered as a character inside the string value.

Use two single quotes to escape a ' character in string functions.

For example, expression @concat('Baba', '''s ', 'book store') will return below result.

Baba's book store
