sqliteHow do I use the SQLite zfill function?

The zfill() function in SQLite is used to pad a string with leading zeros. This is helpful when you need to ensure that all strings have a certain number of characters, such as when dealing with numeric codes or identifiers.

For example, the following code will pad a string with leading zeros to make it five characters long:

SELECT zfill('ABC', 5);

The output of this code would be 00ABC.

The code consists of two parts:

• zfill(): the SQLite function used to pad a string with leading zeros
• 'ABC': the string to be padded
• 5: the number of characters the string should be padded to

Here are a few more examples of zfill() in action:

SELECT zfill('123', 5);

The output of this code would be 00123.

SELECT zfill('ABCD', 5);

The output of this code would be ABCD.

For more information about the zfill() function in SQLite, see the SQLite documentation.
