You can achieve this by creating a queue worker that is constantly running and checks for new files in the S3 bucket.When a new file is uploaded to the S3 bucket, you can use an event listener to detect the new file and dispatch a job to handle the file processing.

This setting determines the language and territory preferences for sorting, formatting, and displaying data in the database.

5 min readTo catch a timeout exception in Laravel queue, you can use the onConnection method when dispatching a job to specify a timeout value. This will set a maximum time limit for the job to complete. If the job exceeds this timeout, a timeout exception will be thrown. You can then catch this exception using a try-catch block and handle it as needed in your application logic. Additionally, you can also configure the retry_after value in your queue.

5 min readTo parse text in an Oracle query, you can use various string functions such as SUBSTR, INSTR, and REGEXP functions. These functions help in extracting specific parts of the text, splitting text based on delimiters, and performing pattern matching respectively. By combining these functions with the SELECT statement in your query, you can effectively parse text data stored in Oracle tables. Additionally, you can also use PL/SQL blocks and cursors for more complex parsing requirements.

5 min readTo remove a table from the cache in Oracle, you can use the ALTER TABLE command with the NOCACHE option. By specifying this option, you are indicating that the table should not be cached in the buffer cache. This means that data from the table will not be stored in memory, but will be read and written directly to disk. This can be useful if you have tables that are large and infrequently accessed, as it can help to free up space in the buffer cache for more frequently accessed data.

5 min readIn Laravel, you can load nested relationships using eager loading. Eager loading allows you to load multiple relationships at once when querying your database. To load nested relationships, you can use the with method when querying your models.For example, if you have a User model that has a posts relationship, and each Post has a comments relationship, you can load both relationships like this: $user = User::with('posts.

4 min readTo convert comma separated values to rows in Oracle, you can use the SQL function "REGEXP_SUBSTR" along with a recursive SQL query. First, use the function to extract individual values from the comma-separated list. Then, use a recursive query to iterate through each value and insert it into a new row in a temporary table. This process may involve creating a separate table, using a loop to iterate through the values, and inserting them into rows accordingly.
