5 min readTo get the ID of the last row inserted in Oracle, you can use the RETURNING clause in your INSERT statement. This clause allows you to retrieve the value of the column that was just inserted.
-
5 min readTo feed Python lists into TensorFlow, you first need to convert them into a TensorFlow tensor object. This can be done using the tf.constant method, which creates a constant tensor from a Python list. Once the list is converted into a TensorFlow tensor, you can feed it into your TensorFlow model as input data. Alternatively, you can use the tf.data.Dataset API to create a dataset from the Python list and then feed the dataset into your model.
-
7 min readTo return a result data type in Rust, you can use the Result enum. The Result enum has two variants: Ok and Err. When a function successfully returns a value, you can wrap that value with the Ok variant. If there is an error, you can wrap the error with the Err variant.
-
4 min readTo update a column with a date in Oracle, you can use the following SQL query:UPDATE table_name SET column_name = TO_DATE('your_date_here', 'date_format_here') WHERE condition_here;In this query:Replace table_name with the name of the table you want to update.Replace column_name with the name of the column you want to update with a date.Replace your_date_here with the desired date in the format 'YYYY-MM-DD'.
-
4 min readTo verify an optimized model in TensorFlow, you can evaluate its performance on a separate validation dataset or test dataset. This involves loading the saved model, loading the validation or test dataset, and then using the model to predict the outputs of the input data. You can compare these predicted outputs with the ground truth labels of the validation or test dataset to see how well the model is performing.
-
5 min readTo reset the username and password for an Oracle database, you need to first log in to the Oracle database as a privileged user, such as SYS or SYSTEM. Once logged in, you can use the ALTER USER command to reset the password for a specific user by specifying the new password in the command.To reset the username, you may need to create a new user with the desired username and assign the necessary privileges to this user. You can do this by using the CREATE USER and GRANT commands.
-
6 min readTo translate JavaScript promises to Rust, you can use the Rust Future trait. Promises in JavaScript represent the eventual completion or failure of an asynchronous operation, similar to futures in Rust. You can create a future in Rust using the Future trait and implement the necessary methods such as poll, map, and_then, and await to handle the asynchronous operations.
-
4 min readTo get a summary of pivot rows in Oracle, you can use the GROUP BY clause along with aggregate functions such as COUNT(), SUM(), AVG(), etc. to calculate summary values for each group of pivot rows. By grouping the pivot rows based on certain criteria, you can generate summary information such as totals, averages, counts, or other statistics for the data in the pivot rows.
-
4 min readTo reverse a rust string in-place using recursion, you can create a recursive function that takes a mutable reference to the string and two indices representing the start and end points of the substring to be reversed. Within the function, you can swap the characters at the start and end indices, then recursively call the function with the start index incremented and the end index decremented until the start index is greater than or equal to the end index.
-
3 min readTo fetch only uppercase values in Oracle, you can use the UPPER function in your SQL query. The UPPER function converts a string to uppercase, so you can compare the original value with its uppercase version to filter out only the uppercase values. For example, you can use a WHERE clause like this:SELECT column_name FROM table_name WHERE column_name = UPPER(column_name);This query will return only the rows where the column value is in uppercase.
-
6 min readTo grayscale an image captured from a camera in Rust, you can use the image crate to read the image, convert it to grayscale, and save the new grayscale image. First, you need to capture the image from the camera using a library like the camera-capture crate. Once you have the image data, you can use the image crate to read the image data, convert it to grayscale using the rgb_image.grayscale() function, and save the new image using the image::io::Reader struct and the save function.
