3 min readTo hide a column in a row in Oracle, you can use the SELECT statement to exclude the column from the result set. Instead of selecting all columns using "*", specify the columns you want to display explicitly in the SELECT statement. This will exclude the hidden column from the output while displaying the rest of the columns in the row. Alternatively, you can also use an alias for the column you want to hide in the SELECT statement, effectively obscuring its original name in the output.

4 min readTo insert the sum of two tables in Oracle, you can use a SQL query that joins the two tables and calculates the sum of the desired columns. You can use the SELECT statement with the SUM function to add up the values from the columns in the two tables. Make sure to specify the columns you want to sum up and use the appropriate join condition to combine the data from the two tables. Once you have calculated the sum, you can insert it into a new table or display the result as needed.

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.

4 min readIn Oracle DB, the 'NSL' character refers to the National Language Support setting for the database. This setting determines the language and territory preferences for sorting, formatting, and displaying data in the database. The NSL character is used to define the character set and linguistic sorting behavior for the database. It is important to configure the NSL settings correctly to ensure proper handling of language-specific data within the Oracle 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.

3 min readTo use the sum query in Laravel, you can utilize the sum() method provided by the Query Builder. This method allows you to calculate the sum of a specific column in a database table. You can specify the column you want to calculate the sum for within the sum() method, and then execute the query to retrieve the calculated sum.

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.
