Download

pip install NewSimpleSQL

How connect your database:

-SQLite

from NewSimpleSQL.SimpleSQLite import Database

#With auto commit
database: Database = Database('example_database.db')

#Without auto commit
database: Database = Database('example_database.db', False)

How to create tables in your database:

-SQLite

from NewSimpleSQL.SimpleSQLite import Database

database: Database = Database('example_database.db')

#Create one table
database.simple_create_table({
    "name" : "example_table",
    "columns" : {
        "id" : (int,)
        "default_number" : [int, 0],
        "number_constraints" : {
            "type" : int,
            "constraints" : "CHECK (number_constraints > 18)"
        }
    }
})

#Create multiple tables
database.complicated_create_tables([
    {
        "name" : "example_table_2",
        "columns" : {
            "id" : ID(int),
            "number_of_the_first_table" : int
        },
        "fk" : {
            "number_of_the_first_table" : ("example_table", "default_number")
            # Table column name : (Name of the other table, Column of the other table)
        }
    }
    #Other tables
])

Column Types:

SQLite

• int = INTEGER
• float = REAL
• str = TEXT
• sqlite3.Blob|Blob = BLOB
• Numeric() = NUMERIC

IDs, defaults y constraints:

SQLite

• (id_type[int|str],)|ID(int|str) = id_type PRIMARY KEY
• [column_type[int|str], value] = column_type DEFAULT value
• { "type" : type, "constraints" : str } = "type" "constraints"

How to get data from the database:

from NewSimpleSQL.SimpleSQLite import Database

database: Database = Database('example_database.db')

#Get data from one table
database.simple_select_data("table_name", "column1, column2, ..., column_infinity"|"*", 'WHERE column1 = 0 ORDER BY column1'|None, one_fetch=True|False)

#Get data from multiple table
database.complicated_select_data([
    {
        "name" : "table_name",
        "column" : "column1, column2, column3, ..., column_infinity",
        "condition" : "WHERE column1 = 0 ORDER BY column1",
        "fetch" : False
    },
    {
        "name" : "table_name_2",
        "column" : "column1, column2, column3, ..., column_infinity",
        "condition" : "WHERE column2 = 0 ORDER BY column2",
        "fetch" : True
    }
])

How to Insert Data into the Database:

from NewSimpleSQL.SimpleSQLite import Database

database: Database = Database('example_database.db')

#Insert data into a single table
database.simple_insert_data("table_name", (value1, value2, value3, ..., value_infinity))

#Insert data into one or more tables
database.complicated_insert_data({
    "table_name" : (value1, value2, value3, ..., value_infinity),
    "table_name_2" : (value1, value2, value3, ..., value_infinity)
})

How to update data in the database:

from NewSimpleSQL.SimpleSQLite import Database

database: Database = Database('example_database.db')

#Update data in a single table
database.simple_update_data("table_name", 'column1 = 0, column2 = "Hello", column3 = False', 'WHERE column1 != 0')

#Update data in one or more tables
database.complicated_update_data([
    {
        "name" : "example_table",
        "columns" : 'column1 = 0, column4 = "Bye"',
        "condition" : 'WHERE column1 != 0'
    },
    {
        "name" : "example_table_2",
        "columns" : 'column1 = 0, column4 = "Bye"',
        "condition" : 'WHERE column4 != "Bye"'
    }
])

These are all the basic commands.

Por ahora, solo tiene soporte son SQLite3

Descarga

pip install NewSimpleSQL

Como usar la libreria

Importar la libreria:

import NewSimpleSQL

Como conectarte a tu base de datos:

-SQLite

from NewSimpleSQL.SimpleSQLite import Database

#Con auto commit
database: Database = Database('example_database.db')

#Sin auto commit
database: Database = Database('example_database.db', False)

Como crear tablas en tu base de datos:

-SQLite

from NewSimpleSQL.SimpleSQLite import Database

database: Database = Database('example_database.db')

#Crear una tabla
database.simple_create_table({
    "name" : "tabla_de_ejemplo",
    "columns" : {
        "id" : ID()
        "numero_por_defecto" : [int, 0],
        "restriccion_de_numero" : {
            "type" : int,
            "constraints" : "CHECK (restriccion_de_numero > 18)"
        }
    }
})

#Crear varias tablas
database.complicated_create_tables([
    {
        "name" : "tabla_de_ejemplo_2",
        "columns" : {
            "id" : ID(str, auto_increment=False),
            "numero_de_la_primera_tabla" : int
        },
        "fk" : {
            "numero_de_la_primera_tabla" : ("tabla_de_ejemplo", "numero_por_defecto")
            # Nombre de la columna de la tabla : (Nombre de la otra tabla, Columna de la otra tabla)
        }
    }
    #Otras tablas
])

Tipos de columnas:

SQLite

• int = INTEGER
• float = REAL
• str = TEXT
• sqlite3.Blob|Blob = BLOB
• Numeric() = NUMERIC

IDs, defaults y constraints:

SQLite

• ID(int|str, auto_increment=True|False) = id_type PRIMARY KEY
• (column_type,) = column_type NOT NULL
• [column_type[int|str], value] = column_type DEFAULT value
• { "type" : type, "constraints" : str } = "type" "constraints"

Como conseguir datos de la base de datos:

from NewSimpleSQL.SimpleSQLite import Database

database: Database = Database('example_database.db')

#Conseguir datos de una tabla
database.simple_select_data("table_name", "column1, column2, ..., column_infinity"|"*", 'WHERE column1 = 0 ORDER BY column1'|None, one_fetch=True|False)

#Conseguir datos de varias tablas
database.complicated_select_data([
    {
        "name" : "table_name",
        "column" : "column1, column2, column3, ..., column_infinity",
        "condition" : "WHERE column1 = 0 ORDER BY column1",
        "fetch" : False
    },
    {
        "name" : "table_name_2",
        "column" : "column1, column2, column3, ..., column_infinity",
        "condition" : "WHERE column2 = 0 ORDER BY column2",
        "fetch" : True
    }
])

Como insertar datos en la base de datos:

from NewSimpleSQL.SimpleSQLite import Database

database: Database = Database('example_database.db')

#Insertar datos en una sola tabla
database.simple_insert_data("table_name", (value1, value2, value3, ..., value_infinity))

#Insertar datos en una o mas tablas
database.complicated_insert_data({
    "table_name" : (value1, value2, value3, ..., value_infinity),
    "table_name_2" : (value1, value2, value3, ..., value_infinity)
})

Como actualizar datos en la base de datos:

from NewSimpleSQL.SimpleSQLite import Database

database: Database = Database('example_database.db')

#Actualizar datos en una sola tabla
database.simple_update_data("table_name", 'column1 = 0, column2 = "Hola", column3 = False', 'WHERE column1 != 0')

#Actualizar datos en una o mas tablas
database.complicated_update_data([
    {
        "name" : "example_table",
        "columns" : 'column1 = 0, column4 = "Adios"',
        "condition" : 'WHERE column1 != 0'
    },
    {
        "name" : "example_table_2",
        "columns" : 'column1 = 0, column4 = "Adios"',
        "condition" : 'WHERE column4 != "Adios"'
    }
])

Estos son todos los comandos basicos.
