SQL Seeder

This Go package provides a tool for generating SQL INSERT statements from JSON or Excel data. It supports various relationships between tables (one-to-many and many-to-many) and allows you to customize the delimiters used in your data.

Features

• Seed from JSON or Excel: Generate SQL from structured data in either JSON or Excel format.
• Relationship Support: Handles one-to-many and many-to-many relationships between tables.
• Customizable Delimiters: Configure the delimiters used in your data for flexible parsing.
• Templating: Uses Go templates to generate the SQL statements, allowing for customization.

Installation

go get github.com/darwishdev/sqlseeder

Usage

1. Define your data

JSON:

[
  {
    "id": "1",
    "name": "Product 1",
    "category_id**categories**category_name": "Electronics",
    "tag_id***product_tags***tags***tag_name***product_name": "tag1|tag2"
  },
  {
    "id": "2",
    "name": "Product 2",
    "category_id**categories**category_name": "Books",
    "tag_id***product_tags***tags***tag_name***product_name": "tag3"
  }
]

Excel:

id	name	category_idcategoriescategory_name	tag_idproduct_tagstagstag_nameproduct_name
1	Product 1	Electronics	tag1
2	Product 2	Books	tag3

2. Create a Seeder

import "github.com/your-module-path/sqlseeder"

// Configure delimiters (optional)
config := sqlseeder.SeederConfig{
  OneToManyDelimiter:     "**",
  ManyToManyRowDelimiter: "|",
  ManyToManyDelimiter:    "***",
}

seeder := sqlseeder.NewSeeder(config)

3. Generate SQL

From JSON:

jsonContent := // Load your JSON data
sqlString, err := seeder.SeedFromJSON(bytes.NewBuffer(jsonContent), "your_schema", "your_table")
if err != nil {
  // Handle error
}
fmt.Println(sqlString)

From Excel:

excelContent := // Load your Excel data
sqlString, err := seeder.SeedFromExcel(bytes.NewBuffer(excelContent), "your_schema", "your_table", "Sheet1")
if err != nil {
  // Handle error
}
fmt.Println(sqlString)

Column Name Formulas

• One-to-many: <primary_key_column><OneToManyDelimiter><table_name><OneToManyDelimiter><search_key_column>
• Many-to-many: <joining_table_primary_key><ManyToManyDelimiter><joining_table_name><ManyToManyDelimiter><second_table_name><ManyToManyDelimiter><second_table_search_column><ManyToManyDelimiter><first_table_search_column>
