How Do I Ensure Correct Newline Insertion in nvarchar Fields Using REPLACE in SQL Server?

Correctly Inserting Newline into nvarchar

Replacing HTML break tags with newlines in rich text using the REPLACE function can sometimes result in missing line breaks. This is not due to an error in the function, but rather a setting in the SQL Server Management Studio (SSMS).

To correctly insert newlines into an nvarchar field, follow these steps:

1. Open SSMS and navigate to the following options: Tools -> Options -> Query Results -> SQL Server -> Results to Grid.
2. Under the "Results to Grid" section, locate the option "Retain CR/LF on copy or Save."
3. Ensure that the option is ticked.

By ticking this option, you instruct SSMS to retain carriage returns (CR) and line feeds (LF) when copying or saving data from the grid. This ensures that newlines will be correctly inserted into the nvarchar field, as intended.

Once this setting is enabled, you can use the REPLACE function to replace HTML break tags with newlines as follows:

SET @rich_text_to_modify = REPLACE(@rich_text_to_modify, '<br>', CHAR(13) + CHAR(10))

This will correctly insert newlines into the nvarchar field, resulting in the desired text formatting.
