5 min readTo compare two Arabic strings in Oracle, you can use the NLS_SORT parameter to specify the linguistic sort order. This parameter determines how characters are compared in the database based on the specified language or locale. You can set the NLS_SORT parameter to a specific Arabic linguistic sort order, such as 'ARABIC' or 'ARABIC_AI' (for Arabic AI). This will ensure that the comparison is done based on the Arabic language rules for sorting characters.

6 min readTo join aggregated data in another table in Oracle, you can use the GROUP BY clause to aggregate data in one table, and then join the aggregated data with another table. This can be achieved by first using the GROUP BY clause to group data in one table based on a certain criterion, and then using the JOIN clause to join the aggregated data with another table based on a common key or column.

4 min readTo get the first line of a string in an Oracle query, you can use the REGEXP_SUBSTR function along with a regular expression pattern that captures the first line of text. For example, you can use the following SQL query:SELECT REGEXP_SUBSTR(your_column_name, '^[^\n]*') FROM your_table_name;This query will return the first line of text from the specified column in your table. You can adjust the regular expression pattern as needed to capture the specific format of your text data.
-
9 min readTo compare two sets of rows in Oracle, you can use the MINUS operator. The MINUS operator is used to retrieve all rows from the first query that are not present in the second query.First, you would write your two SELECT queries that retrieve the rows you want to compare. Then, you would use the MINUS operator between the two queries to get the rows that are in the first query but not in the second query.

5 min readTo prevent "bad" dates in Oracle, it is important to follow certain best practices. One way to prevent issues with dates is to always store dates in the proper datatype, such as the DATE datatype, rather than as strings or numbers. This helps to ensure that date operations will work correctly and consistently.
-
4 min readTo update a column using select in Oracle, you can use a subquery in the UPDATE statement. You can select the values you want to update the column with in the subquery, and then use that subquery in the SET clause of the UPDATE statement. This will allow you to update the column based on the results of the select query. Make sure the subquery returns only one value for each row that you want to update, otherwise you may encounter errors.

6 min readStreaming videos work by transmitting data from a server to a user's device in real-time, allowing the user to watch the video as it is being downloaded. When a user clicks on a video to watch, the server sends small packets of data to the user's device, which are then displayed as video and audio on the screen.Streaming videos differ from downloading videos in that the data is not saved permanently on the device, but rather is played as it is being received.

7 min readA trigger is a stored program in an Oracle database that automatically executes when a specified event occurs (such as adding, modifying, or deleting data in a table). Triggers are designed to enforce business rules, data integrity, and other database constraints.

2 min readYou can get a file path without the extension in PowerShell by using the "GetFileNameWithoutExtension" method from the "System.IO.Path" class. This method will return the file name without the extension. Here is an example code snippet: $file = "C:\Path\To\File.txt" $fileNameWithoutExtension = [System.IO.Path]::GetFileNameWithoutExtension($file) Write-Host $fileNameWithoutExtension This will output "File" as the result, without the ".txt" extension.

7 min readTo write super-fast file-streaming code in C#, it is important to utilize asynchronous programming techniques to improve the responsiveness and efficiency of reading and writing files. By using asynchronous methods such as ReadAsync and WriteAsync from the FileStream class, you can avoid blocking the main thread and improve the overall performance of your code.

5 min readTo save a stream to disk in PowerShell, you can use the Out-File cmdlet. This cmdlet allows you to redirect the output of a command or script to a file on disk.For example, you can save the output of a command to a text file by using the following syntax: Get-Process | Out-File -FilePath "C:\output.txt" This command will save the output of the Get-Process cmdlet to a file named output.txt located in the C:\ directory.
