How to use Xano’s SQL editor for custom queries?

Access the SQL Editor

Step 1: Log in to the Xano platform and head over to your project dashboard.
Step 2: On the left-hand menu, find and click on the Database section.
Step 3: Inside the Database section, look for and click on the SQL Editor tab.

Understand the Layout

Step 4: Get comfy with the SQL Editor interface. You'll see a query input area where you can write your SQL queries and an output section where the results will pop up.

Write a Basic Query

Step 5: In the query input area, start with a simple SQL query. For example:
```sql
SELECT * FROM your_table_name;
```

Execute the Query

Step 6: Hit the Run button near the query input area.
Step 7: Check out the results in the output section below the query input area.

Filter Results with a WHERE Clause

Step 8: Tweak your basic query to filter results. For example:
```sql
SELECT * FROM your_table_name WHERE column_name = 'value';
```
Step 9: Click Run again to execute the updated query and see the filtered results.

Utilize Advanced SQL Functions

Step 10: Try out more complex queries. For instance, use the JOIN statement to merge data from multiple tables:
```sql
SELECT a.column1, b.column2
FROM table_a AS a
JOIN table_b AS b ON a.common_column = b.common_column;
```
Step 11: Run the query by clicking the Run button.

Review and Troubleshoot Errors

Step 12: If you hit an error, check out the error message in the output section.
Step 13: Double-check your SQL syntax, fix any issues, and re-run the query.

Save Frequently Used Queries

Step 14: Save queries you use often by copying them to a text file or using Xano’s query storage features, if available.

Export Query Results

Step 15: If you need to export the results, look for an export option in the SQL Editor, or just copy and paste the results into a CSV file.

Optimize Queries for Performance

Step 16: Think about adding indexes to tables to speed up query execution.
Step 17: Use the EXPLAIN command to analyze and optimize your queries:
```sql
EXPLAIN SELECT * FROM your_table_name WHERE column_name = 'value';
```
