pysqlizer 1.0.2

A Python library for dynamically generating SQL queries.

Pysqlizer

Pysqlizer is a Python library for dynamically generating SQL queries based on tuple length and optimizing query generation efficiency.

Installation

Install via pip:

pip install pysqlizer

Usage

sqlify

Function Signature:

sqlify(keyColumn: str, data: list, raiseException: bool = False, how: str = "IN", condition: str = "OR") -> str

Parameters:

• keyColumn (str): The column name on which the condition will be applied.
• data (list): List of values to be used in the query.
• raiseException (bool, optional): If True, raises an error for an empty data list. Default is False.
• how (str, optional): SQL condition type (IN, NOT IN, LIKE, NOT LIKE). Default is IN.
• condition (str, optional): Logical condition between multiple statements (AND, OR). Default is OR.

Examples:

from pysqlizer import sqlify

# Case 1: Basic IN condition
print(sqlify("product_id", [101, 102, 103]))
# Output: "product_id IN (101, 102, 103)"

# Case 2: NOT IN condition
print(sqlify("category_id", [5, 6], how="NOT IN"))
# Output: "category_id NOT IN (5, 6)"

# Case 3: LIKE condition
print(sqlify("product_name", ["phone", "laptop"], how="LIKE", condition="AND"))
# Output: "(product_name LIKE '%phone%' AND product_name LIKE '%laptop%')"

# Case 4: NOT LIKE condition
print(sqlify("product_name", ["tablet", "watch"], how="NOT LIKE", condition="OR"))
# Output: "(product_name NOT LIKE '%tablet%' OR product_name NOT LIKE '%watch%')"

# Case 5: Empty list without exception
print(sqlify("user_id", [], how="IN"))
# Output: "(1=0)" (safe fallback for empty lists)

# Case 6: Empty list with exception
print(sqlify("user_id", [], raiseException=True))
# Raises ValueError: "data list cannot be empty when raiseException=True"

sqlifylike

Function Signature:

sqlifylike(keyColumn: str, data: list|tuple|int|str|dict|set|empty_data, how: str = "LIKE", condition: str = "OR") -> str

Parameters:

• keyColumn (str): The column name on which the condition will be applied.
• data (list): List of values to be used in the LIKE conditions.
• how (str, optional): SQL condition type (LIKE or NOT LIKE). Default is LIKE.
• condition (str, optional): Logical condition between multiple statements (AND, OR). Default is OR.

Examples:

from pysqlizer import sqlifylike

# Case 1: LIKE condition with OR
print(sqlifylike("product_name", ["phone", "laptop"]))
# Output: "(product_name LIKE '%phone%' OR product_name LIKE '%laptop%')"

# Case 2: LIKE condition with AND
print(sqlifylike("product_name", ["phone", "laptop"], condition="AND"))
# Output: "(product_name LIKE '%phone%' AND product_name LIKE '%laptop%')"

# Case 3: NOT LIKE condition with OR
print(sqlifylike("product_name", ["tablet", "watch"], how="NOT LIKE"))
# Output: "(product_name NOT LIKE '%tablet%' OR product_name NOT LIKE '%watch%')"

# Case 4: NOT LIKE condition with AND
print(sqlifylike("product_name", ["tablet", "watch"], how="NOT LIKE", condition="AND"))
# Output: "(product_name NOT LIKE '%tablet%' AND product_name NOT LIKE '%watch%')"
