The Sqlite.py file contains several very specific queries: select_Query = "select sqlite_version()" delete_query = "DELETE from Database where id = "+str(id) sel = 'SELECT id FROM Database WHERE name == "{0}"'.format(value) insert_query = """INSERT INTO Database (id, name, photo, html) VALUES (?, ?, ?, ?)""" sqlite_select_query = """SELECT * from Database""" table_query = '''CREATE TABLE Database ( id INTEGER PRIMARY KEY, name TEXT NOT NULL, photo text NOT NULL UNIQUE, html text NOT NULL UNIQUE)''' Write a QueryBuilder function. The QueryBuilder builds a generic Query to build ANY Query type (i.e. version, delete, select, insert, select, table). The QueryBuilder parameters require: The type of Query, the input tuple data and then constructs a query string based on the parameters. def QueryBuilder( Data_Base, Query_Type, Query_Tuple): ''' ''' Build Query_String ''' ''' return Query_String
SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.
The Sqlite.py file contains several very specific queries:
select_Query = "select sqlite_version()"
delete_query = "DELETE from
sel = 'SELECT id FROM Database WHERE name == "{0}"'.format(value)
insert_query = """INSERT INTO Database (id, name, photo, html) VALUES (?, ?, ?, ?)"""
sqlite_select_query = """SELECT * from Database"""
table_query = '''CREATE TABLE Database (
id INTEGER PRIMARY KEY,
name TEXT NOT NULL,
photo text NOT NULL UNIQUE,
html text NOT NULL UNIQUE)'''
Write a QueryBuilder function. The QueryBuilder builds a generic Query to build ANY Query type (i.e. version, delete, select, insert, select, table). The QueryBuilder parameters require: The type of Query, the input tuple data and then constructs a query string based on the parameters.
