MySQL Syntax Error: 'You have an error in your SQL syntax...' - Troubleshooting Guide

This error message indicates a problem with the SQL syntax, specifically within the VALUES clause. The error arises when trying to insert data into the 'tbl_dictionary_type' table using the following statement:

'insert into tbl_dictionary_type(code, name, description) values (UUID(), ${name}, ${description})'

The issue lies in the use of '${name}' and '${description}' within the VALUES clause. These expressions are not valid SQL syntax. Instead, you should utilize parameter placeholders and bind values during execution.

Correct SQL Syntax with Parameter Placeholders:

'insert into tbl_dictionary_type(code, name, description) values (UUID(), ?, ?)'

This syntax allows you to insert values into the table safely and securely. Replace the question marks with actual values during SQL execution.

Generating UUIDs:

The UUID() function generates unique identifiers. It is recommended to generate the UUID in your application code and pass it as a parameter to the SQL statement.

Key Takeaways:

• Avoid using '${}' expressions directly within SQL statements. Instead, use parameter placeholders (e.g., '?').
• Ensure proper SQL syntax to avoid errors during database operations.
• Generate unique identifiers like UUIDs in your application code and pass them to your SQL queries.
