+# Oracle Data Hygiene: English Character Extraction
+
+This guide covers the most efficient ways to retrieve only English letters ($A-Z$, $a-z$) and numbers ($0-9$) from an Oracle Database.
+
+---
+
+## 1. The Core Methods
+
+### A. The `REGEXP_REPLACE` Method
+Best for readability and one-off queries.
+```sql
+SELECT REGEXP_REPLACE(column_name, '[^a-zA-Z0-9]', '') AS clean_data
+FROM your_table;
+```
+
+### B. The `TRANSLATE` Method
+Best for high-performance and large datasets. It is significantly faster than Regex because it avoids the overhead of the regular expression engine.
+```sql
+SELECT TRANSLATE(column_name, 
+                 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789' || column_name, 
+                 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789') AS clean_data
+FROM your_table;
+```
+
+---
+
+## 2. Automating the Process
+
+### The Reusable Function
+Instead of typing the long string of letters every time, create this function once:
+
+```sql
+CREATE OR REPLACE FUNCTION clean_alphanumeric(p_str IN VARCHAR2) 
+RETURN VARCHAR2 DETERMINISTIC IS
+    v_keep VARCHAR2(62) := 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
+BEGIN
+    RETURN TRANSLATE(p_str, v_keep || p_str, v_keep);
+END;
+/
+```
+
+### The "Auto-View" Generator
+Run this script to generate a `CREATE VIEW` statement for any table. It automatically applies the cleanup to every `VARCHAR2` and `CHAR` column by querying the Data Dictionary. High-Speed parallel indexes and a series of GRANT statements in one go.
+
+```sql
+SELECT 
+    DBMS_XMLGEN.CONVERT(
+        XMLAGG(
+            XMLELEMENT(e,

+## 3. Performance Summary
+
+| Feature | `REGEXP_REPLACE` | `TRANSLATE` |
+| :--- | :--- | :--- |
+| **Speed** | Slower (Engine overhead) | **Very Fast** (Native mapping) |
+| **Ease of Use** | High (Short syntax) | Moderate (Requires long strings) |
+| **Flexibility** | High (Supports ranges) | Low (Must list every char) |
+
+---
+
+## 4. Best Practices & Tips
+
+* **Case Standardization:** To force everything to Uppercase while cleaning, wrap the result: `UPPER(TRANSLATE(...))`.
+* **Function-Based Indexes:** If you frequently query the "cleaned" version of a column, create a function-based index to prevent full table scans.
+* **Accented Characters:** Note that characters like `é` or `ñ` will be removed by these methods. If you need to keep them, use the `[:alpha:]` regex class instead.

+# React + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## React Compiler
+
+The React Compiler is not enabled on this template. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the [TS template](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-react-ts) for information on how to integrate TypeScript and [`typescript-eslint`](https://typescript-eslint.io) in your project.
