Simple Operation Conditions

Overview

The simpleOperationConditions module provides functions for processing and converting simple operation conditions in SQL queries. These conditions include basic comparison operations such as equality, inequality, greater than, less than, etc.

Types

simpleOp

Represents the structure of simple operation conditions.

• =: Equals
• >: Greater than
• <: Less than
• >=: Greater than or equal to
• <=: Less than or equal to
• !=: Not equal to

simpleOperation

Defines a simple operation condition for a specific field.

• Field Name: The name of the field to apply the condition to.
• Value: Can be a single simple operation or an array of simple operations.

simpleOperationConditionType

Extends simpleOperation to include logical operators ($and and $or) for combining multiple conditions.

• $and: Specifies conditions that must all be true.
• $or: Specifies conditions where at least one must be true.

Functions

processSimpleOperationConditions

Processes simple operation conditions into SQL format.

• Parameters:
  • conditions: The conditions to process.
  • subOperator: The sub-operator to use when combining multiple conditions.
  • type: The type of condition (e.g., $and, $or).
• Returns: The processed SQL condition string.

simpleOperationConditions

Converts simple operation conditions into SQL format.

• Parameters:
  • condition: The condition to convert.
  • subOperator (optional): The sub-operator to use when combining multiple conditions.
• Returns: The SQL condition string.

Usage

Example usage of the simpleOperationConditions module:

import { simpleOperationConditions } from "mysql-query-geniex";;
const condition = {
    field1: { '>': 10 },
    $and: {
        field2: { '<=': 20 },
        field3: { '=': 'value' }
    }
};

const sqlCondition = simpleOperationConditions(condition);
console.log(sqlCondition);

This will output the SQL condition string based on the provided conditions.
