# ENUM Type Fix - Execution Instructions

## Problem
The database has PostgreSQL ENUM types, but Hibernate is configured to use VARCHAR with CHECK constraints. This causes the error:
```
ERROR: column "contract_nature" is of type ted.contract_nature but expression is of type character varying
```

## Solution
Execute the `fix-enum-types-comprehensive.sql` script on the remote database.

## Execution Methods

### Option 1: Using psql (Recommended)

```bash
psql -h 94.130.218.54 -p 5432 -U postgres -d Sales -f fix-enum-types-comprehensive.sql
```

When prompted, enter password: `PDmXRx0Rbk9OFOn9qO5Gm/mPCfqW8zwbZ+/YIU1lySc=`

### Option 2: Using psql with inline password (Windows PowerShell)

```powershell
$env:PGPASSWORD="PDmXRx0Rbk9OFOn9qO5Gm/mPCfqW8zwbZ+/YIU1lySc="
psql -h 94.130.218.54 -p 5432 -U postgres -d Sales -f fix-enum-types-comprehensive.sql
```

### Option 3: Copy-paste into database client

If you're using DBeaver, pgAdmin, or another GUI tool:

1. Connect to:
   - Host: `94.130.218.54`
   - Port: `5432`
   - Database: `Sales`
   - Username: `postgres`
   - Password: `PDmXRx0Rbk9OFOn9qO5Gm/mPCfqW8zwbZ+/YIU1lySc=`

2. Open `fix-enum-types-comprehensive.sql` in the query editor

3. Execute the entire script

## What the script does

1. ✅ Converts ENUM columns to VARCHAR(50) while preserving existing data
2. ✅ Drops the old ENUM types
3. ✅ Adds CHECK constraints for data validation
4. ✅ Updates the search function to use VARCHAR parameters
5. ✅ Shows verification query at the end

## Verification

After execution, you should see:

```
status                                       | column_name           | data_type         | character_maximum_length
---------------------------------------------|-----------------------|-------------------|--------------------------
ENUM types successfully converted to VARCHAR!| contract_nature       | character varying | 50
ENUM types successfully converted to VARCHAR!| notice_type           | character varying | 50
ENUM types successfully converted to VARCHAR!| procedure_type        | character varying | 50
ENUM types successfully converted to VARCHAR!| vectorization_status  | character varying | 50
```

## After execution

Restart your Spring Boot application. The error should be resolved and the application will be able to insert data into the database.
