Answer 1

To extend existing answers, starting from SQLite 3.34.0:

The substr() SQL function can now also be called "substring()" for compatibility with SQL Server.

substring(X,Y) "substring()" is an alias for "substr()" beginning with SQLite version 3.34.

Answer 2

To get the substring in SQLite

You can use the builtin function in SQLite which is substr(X,Y,Z). The x field represents the string input to be sliced, the y and z field represents the starting point and ending point respectively using an index.

===============================
|Database Table : **articles**|
===============================
|id | description             |
-------------------------------
|29 | Lorem ipsum domit       |
===============================

Now we will try to make a select query for our description

SELECT substr(description,1,4) FROM articles where id='29';

Output would be: Lore instead of Lorem ipsum domit

Answer 3

Use the substr function.

From the list of core functions:

substr(X,Y,Z)
substr(X,Y)

The substr(X,Y,Z) function returns a substring of input string X that begins with the Y-th character and which is Z characters long. If Z is omitted then substr(X,Y) returns all characters through the end of the string X beginning with the Y-th. The left-most character of X is number 1. If Y is negative then the first character of the substring is found by counting from the right rather than the left. If Z is negative then the abs(Z) characters preceding the Y-th character are returned. If X is a string then characters indices refer to actual UTF-8 characters. If X is a BLOB then the indices refer to bytes.
