While trying to insert something like:
"Hello\nWorld"
SQLite throws error something like:
Message: unrecognized token: "'Hello";" (also few other errors)
Even though I convert above string to "Hello''\nWorld" or "Hello\"\n\"World", these escape characters sequences don't work in this case.
Currently using C++ language, I am inserting this column like any other simple string columns. I tried above escape sequence (even though I read in internet that, they don't work with \n).
How to insert new line and other such special characters in SQLite DB?
In SQL, there is no mechanism to escape newline characters; you have to insert them literally:
INSERT INTO MyTable VALUES('Hello
world');
Alternatively, construct the string dynamically:
INSERT INTO MyTable VALUES('Hello' || char(10) || 'world');
(The type of newline (13 or 10 or 13+10) is OS dependent.)
When you embed the SQL statements in C++ strings, you have to escape the newline in the first case:
q1 = "INSERT INTO MyTable VALUES('Hello\nworld');";
q2 = "INSERT INTO MyTable VALUES('Hello' || char(10) || 'world');";
