Deal with new line character “\n” in Sqlite database using Python?

Question

I have a Sqlite database named test.db, which contains two tables with structures like this:

Table1: ID INTEGER PRIMARY KEY AUTOINCREMENT, Name varchar(500), Color varch

Answer 1

Use the replace() SQL function:

cur.execute("SELECT Color, Smell FROM Table1, Table2 "
            "WHERE replace(Table1.Name, '\n', '') = Table2.Name") 

You can update your whole Table Name column to remove the newline characters altogether:

cur.execute("UPDATE Table1 SET Name = replace(Name, '\n', '') "
            "WHERE Name like '%\n%'")
