Notes

In the feed page I need to hide the dotted line in the mobile screens. So here you can see how its can be done in Bootstrap.

• d-none d-md-flex: shows only on md and up (desktop/tablet)

• d-block d-md-none: shows only on mobile

• text-nowrap: prevents text from wrapping

<div class="mb-3">
  <!-- Desktop layout -->
  <div class="d-none d-md-flex align-items-center">
    <a href="{{ .Permalink }}" class="text-decoration-none fw-medium me-2 text-nowrap">
      Sample heading
    </a>
    <div class="flex-grow-1 border-bottom dotted-line mx-2"></div>
    <p class="text-muted small text-nowrap mb-0">Date</p>
  </div>

  <!-- Mobile layout -->
  <div class="d-block d-md-none">
    <a href="{{ .Permalink }}" class="text-decoration-none fw-medium d-block mb-1">
      Sample heading
    </a>
    <p class="text-muted small mb-0">Date</p>
  </div>
</div>

Avinash is sharing some cool facts about SQLite.

• SQLite is the most deployed and most used database. There are over one trillion (1000000000000 or a million million) SQLite databases in active use.

• SQLite is likely used more than all other database engines combined. Billions and billions of copies of SQLite exist in the wild. It’s everywhere.

These are mind blowing, have a look into that.

To extract the value of a tag from the given XML-like string in PL/SQL, you can use the EXTRACTVALUE function or XMLTABLE for XML processing.

Example Using EXTRACTVALUE

DECLARE
    xml_data CLOB := '<Status>200</Status><Message>Success</Message>';
    l_message VARCHAR2(50);
BEGIN
    -- Extract the FunctionalReferenceID value
    l_message := EXTRACTVALUE(XMLTYPE('<root>' || xml_data || '</root>'), '/root/Message');
    
    -- Print the value
    DBMS_OUTPUT.PUT_LINE('FunctionalReferenceID: ' || l_message);
END;

Example Using XMLTABLE

DECLARE
    xml_data CLOB := '<Status>200</Status><Message>Success</Message>';
    l_message VARCHAR2(50);
BEGIN
    -- Use XMLTABLE to extract the Message
    SELECT value
    INTO l_message
    FROM XMLTABLE(
        '/root/Message'
        PASSING XMLTYPE('<root>' || xml_data || '</root>')
        COLUMNS value VARCHAR2(50) PATH '.'
    );

    -- Print the value
    DBMS_OUTPUT.PUT_LINE('Message: ' || l_message);
END;

EXTRACTVALUE, XMLTABLE

For NVARCHAR2 and VARCHAR2 maximum size is 4000 bytes, or 32767 bytes if the MAX_STRING_SIZE initialization parameter is set to EXTENDED. This is useful you have to allocate more data to a variable.

You can run the below command to view the parameter.

show parameter MAX_STRING_SIZE;

In Oracle PL/SQL, you can use the following commands to view table details:

1. DESCRIBE or DESC

   DESC table_name;
   

   Displays columns, data types, and constraints.

2. USER_TAB_COLUMNS

   SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
   FROM USER_TAB_COLUMNS
   WHERE TABLE_NAME = 'TABLE_NAME';
   

   Shows details about columns for tables owned by the user.

3. ALL_TAB_COLUMNS

   SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
   FROM ALL_TAB_COLUMNS
   WHERE TABLE_NAME = 'TABLE_NAME';
   

   Provides column information for tables accessible to the user.

4. DBMS_METADATA.GET_DDL

   SELECT DBMS_METADATA.GET_DDL('TABLE', 'TABLE_NAME') FROM DUAL;
   

   Displays the CREATE TABLE statement for table structure details.

To view constraints on the table, you can check here.

If your Oracle database has Flashback enabled, you can query past versions of data within a specified retention period. Here’s how to use Flashback to retrieve a prior state of data:

SELECT * 
FROM your_table AS OF TIMESTAMP (SYSTIMESTAMP - INTERVAL '5' MINUTE) 
WHERE your_condition;

Replace SYSTIMESTAMP - INTERVAL '5' MINUTE with the timestamp or interval that reflects when the data was last known to be in its old state.

Note: Flashback must be enabled, and it’s only available within the Flashback retention window, which depends on your database configuration.

Breaking columns to a new line in flexbox requires a small hack: add an element with width: 100% wherever you want to wrap your columns to a new line.

<div class="container text-center">
  <div class="row">
    <div class="col-6 col-sm-3">.col-6 .col-sm-3</div>
    <div class="col-6 col-sm-3">.col-6 .col-sm-3</div>

    <!-- Force next columns to break to new line -->
    <div class="w-100"></div>

    <div class="col-6 col-sm-3">.col-6 .col-sm-3</div>
    <div class="col-6 col-sm-3">.col-6 .col-sm-3</div>
  </div>
</div>

You can also apply this break at specific breakpoints with our responsive display utilities.

<div class="container text-center">
  <div class="row">
    <div class="col-6 col-sm-4">.col-6 .col-sm-4</div>
    <div class="col-6 col-sm-4">.col-6 .col-sm-4</div>

    <!-- Force next columns to break to new line at md breakpoint and up -->
    <div class="w-100 d-none d-md-block"></div>

    <div class="col-6 col-sm-4">.col-6 .col-sm-4</div>
    <div class="col-6 col-sm-4">.col-6 .col-sm-4</div>
  </div>
</div>

To update a column with a random value in PL/SQL, you can use the DBMS_RANDOM package, which provides functions for generating random numbers or strings.

To update random number

BEGIN
    UPDATE employees
    SET salary = ROUND(DBMS_RANDOM.VALUE(100, 500));
    COMMIT;
END;

• DBMS_RANDOM.VALUE(100, 500) generates a random decimal number between 100 and 500.
• ROUND is used to convert the decimal value to an integer.

To update random string

BEGIN
   UPDATE employees
    SET password = DBMS_RANDOM.STRING('x', 8);  -- 'x' specifies alphanumeric characters
    COMMIT;
END;

• DBMS_RANDOM.STRING('x', 8) generates an 8-character alphanumeric string.
• ‘x’ specifies alphanumeric characters (letters and numbers). Other options include ‘a’ for alphabets and ‘u’ for uppercase only.

The PL/SQL MINUS operator returns all rows from the first query that are not present in the second query. Each SELECT statement defines a dataset, and the MINUS operator retrieves all records from the first dataset, excluding any that also appear in the second dataset.

select stock_id, stock_name
from stock_master
where active = 'Y'

minus

select stock_poid, stock_desc
from stock_ledger
where transaction_date > '01-JAN-24'

In Hugo, creating different slash pages (like /about/, /uses/, etc.) involves creating specific content files for each page and customizing templates as needed.

• Create individual markdown files for each slash page under content/.
  If you want to create an /about/ page in your blog, add a markdown page with below front matter in the content/ page.

//content/about.md

---
title: "About"
date: 2024-10-16
---

This is the About page content.

• Optionally create a template for the page.
  Hugo uses the single.html template from the layouts/_default/ folder to render pages by default. However, you can create custom templates in the layouts/page/ folder to format specific pages as needed.

//layouts/page/about.html

<h1>{{ .Title }}</h1>
<div class="content">
  {{ .Content }}
</div>

You can check my slash pages like uses, credits, and changelog.
