Creating a Custom Split Function
import sqlite3
def split_string(delimited_text, delimiter=','):
return delimited_text.split(delimiter)
def create_split_function(conn):
conn.create_function("split_string", 1, split_string)
# Connect to the SQLite database
conn = sqlite3.connect(":memory:")
# Create the Product table
conn.execute("CREATE TABLE Product (id INTEGER PRIMARY KEY, names TEXT)")
# Insert sample data
conn.execute("INSERT INTO Product (names) VALUES ('apple,banana'), ('mango,orange')")
# Create the custom split function
create_split_function(conn)
# Usage example
cursor = conn.cursor()
cursor.execute("SELECT id, split_string(names, ',') FROM Product")
print(cursor.fetchall())
# Close the connection
conn.close()
Output:
Explanation: In the above query we use Python code demonstrates how to create a custom SQLite function to split a delimited string. It creates a split_string
function that splits a string into a list based on a given delimiter. This function is then registered with the SQLite connection using create_function
. Finally, the function is used in a SQL query to split the names
column in the Product
table and retrieve the result.
How to Split a Delimited String to Access Individual Items in SQLite?
In SQLite, managing delimited strings can be a common requirement, especially when dealing with data that needs to be stored or manipulated in a database. Delimited strings are essentially strings where items are separated by a specific delimiter character, such as commas, pipes, or tabs. Splitting these strings into individual items can be important for various database operations and queries.
In this article, we will explore different methods to efficiently split delimited strings in SQLite to access individual items with the help of various methods along with the examples and so on.
