Fixing near "": syntax error in SQL with Android Studio

If you're developing an Android application using SQLite and encountering issues with SQL syntax, you're not alone. Many developers face syntax errors that can be puzzling, particularly when inserting data into a database. One common error that many encounter is the infamous near "Hello": syntax error. In this guide, we’ll explore the cause of this error and provide a clear solution to resolve it.

Understanding the Problem

When you add data to your database, you often use the INSERT INTO statement. However, this statement can be very particular about its syntax. Let’s look at the specific error you might be experiencing:

The error occurs because the values being inserted for NAME, DEV, and PLATFORM are not enclosed in single quotes. SQLite requires all string values to be encapsulated within quotes for it to be properly parsed.

The Solution: Enclosing String Values in Quotes

To fix the syntax error, you need to make sure that string values are enclosed in single quotes. Below is the corrected portion of your SQL command within the addGame method:

Important Changes

Add Single Quotes: Notice the addition of single quotes around Name, Dev, and Platform. This tells SQLite that you're inserting string literals, which resolves the syntax issue.

Example of Use

Make sure to call your addGame function with the expected values for Price, Name, Dev, and Platform as strings. Here’s how you might call it:

Conclusion

Syntax errors in SQL can be frustrating, but with a better understanding of how to format your queries correctly, you can avoid them in the future. Always remember to encapsulate string values in single quotes when working with SQLite in Android.

By applying these adjustments, you should be able to insert your data into the database without issues. Happy coding!
