# sql-sp-generation

A Copilot instruction file that pins down SQL conventions: table naming, keys, query style, parameters and stored procedure layout.

## What it does

The rule applies to `**/*.sql` files and steers Copilot while it writes or edits them. It covers three areas at once: schema, query style, and stored procedures.

Schema rules ask for singular table and column names, a primary key called `id`, plus `created_at` and `updated_at` columns. Foreign keys are declared inline, named, and carry `ON DELETE CASCADE` and `ON UPDATE CASCADE`. Queries should use uppercase keywords, list columns explicitly instead of `SELECT *`, qualify columns when several tables are joined, and cap result sets with `LIMIT`/`TOP`. Procedures take a `usp_` prefix in PascalCase, parameters start with `@` in camelCase, and required ones come first.

A separate section covers security: parameterised queries, prepared statements for dynamic SQL, no credentials inside scripts. Transactions are opened and committed explicitly, and procedures that change data get `SET NOCOUNT ON`. Because the file lives in the repository, it binds everyone touching that code — changing the conventions means editing the file itself.

## Install

### GitHub Copilot (native platform)

**Manually: put the files in place**
- File: `.github/instructions/sql-sp-generation.instructions.md` — The applyTo field sets which files it applies to

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/sql-sp-generation.md` — The paths frontmatter field limits the files: move applyTo from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### Cursor

**Manually: put the files in place**
- File: `.cursor/rules/sql-sp-generation.mdc` — Frontmatter: description, globs, alwaysApply. Move applyTo from the source into globs, or the rule will not attach on its own

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/sql-sp-generation.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/sql-sp-generation.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/instructions/sql-sp-generation.instructions.md

## When to use it
- settle on one naming scheme for tables and columns across a team
- stop forgetting `created_at` and `updated_at` on new tables
- declare foreign keys with cascades instead of manual cleanup
- write a stored procedure with a header block and a readable name
- drop `SELECT *` and functions on indexed columns from queries

## Example prompts
- Generate the schema for orders and order items following the sql-sp-generation rules
- Write a stored procedure `usp_GetCustomerOrders` with parameters and a header comment
- Rewrite this query: no `SELECT *`, add a `LIMIT` clause

# SQL Development

## Database schema generation
- all table names should be in singular form
- all column names should be in singular form
- all tables should have a primary key column named `id`
- all tables should have a column named `created_at` to store the creation timestamp
- all tables should have a column named `updated_at` to store the last update timestamp

## Database schema design
- all tables should have a primary key constraint
- all foreign key constraints should have a name
- all foreign key constraints should be defined inline
- all foreign key constraints should have `ON DELETE CASCADE` option
- all foreign key constraints should have `ON UPDATE CASCADE` option
- all foreign key constraints should reference the primary key of the parent table

## SQL Coding Style
- use uppercase for SQL keywords (SELECT, FROM, WHERE)
- use consistent indentation for nested queries and conditions
- include comments to explain complex logic
- break long queries into multiple lines for readability
- organize clauses consistently (SELECT, FROM, JOIN, WHERE, GROUP BY, HAVING, ORDER BY)

## SQL Query Structure
- use explicit column names in SELECT statements instead of SELECT *
- qualify column names with table name or alias when using multiple tables
- limit the use of subqueries when joins can be used instead
- include LIMIT/TOP clauses to restrict result sets
- use appropriate indexing for frequently queried columns
- avoid using functions on indexed columns in WHERE clauses

## Stored Procedure Naming Conventions
- prefix stored procedure names with 'usp_'
- use PascalCase for stored procedure names
- use descriptive names that indicate purpose (e.g., usp_GetCustomerOrders)
- include plural noun when returning multiple records (e.g., usp_GetProducts)
- include singular noun when returning single record (e.g., usp_GetProduct)

## Parameter Handling
- prefix parameters with '@'
- use camelCase for parameter names
- provide default values for optional parameters
- validate parameter values before use
- document parameters with comments
- arrange parameters consistently (required first, optional later)


## Stored Procedure Structure
- include header comment block with description, parameters, and return values
- return standardized error codes/messages
- return result sets with consistent column order
- use OUTPUT parameters for returning status information
- prefix temporary tables with 'tmp_'


## SQL Security Best Practices
- parameterize all queries to prevent SQL injection
- use prepared statements when executing dynamic SQL
- avoid embedding credentials in SQL scripts
- implement proper error handling without exposing system details
- avoid using dynamic SQL within stored procedures

## Transaction Management
- explicitly begin and commit transactions
- use appropriate isolation levels based on requirements
- avoid long-running transactions that lock tables
- use batch processing for large data operations
- include SET NOCOUNT ON for stored procedures that modify data
