MySQL - How to Front Pad Zip Code with "0"

MySQL - how to front pad zip code with 0 ?

Store your zipcodes as CHAR(5) instead of a numeric type, or have your application pad it with zeroes when you load it from the DB. A way to do it with PHP using sprintf():

echo sprintf("%05d", 205); // prints 00205
echo sprintf("%05d", 1492); // prints 01492

Or you could have MySQL pad it for you with LPAD():

SELECT LPAD(zip, 5, '0') as zipcode FROM table;

Here's a way to update and pad all rows:

ALTER TABLE `table` CHANGE `zip` `zip` CHAR(5); #changes type
UPDATE table SET `zip`=LPAD(`zip`, 5, '0'); #pads everything

How to add zero before int in mysql

Don't store the zip codes as int.

Storing the zip-codes as varchar(10) or something like that will keep your zero padding and also cater for alphanumeric zip codes which may be used in some areas.

SQL how to add a leading 0

LPAD should do the job here:

SELECT LPAD ('123', 5, '0');
00123

SELECT LPAD ('12345', 5, '0');
12345

Try:

UPDATE `it_asset_register`.`tab_id_master` 
 SET tab_id_master.ID = LPAD (tab_id_master.ID, 5, '0')
 WHERE ID = '8407' AND LENGTH(tab_id_master.ID)<5 AND LENGTH(tab_id_master.ID)>0;

mySQL removing leading zeros even with data type set as string

You're missing the quotes:

$query_buildzip = "INSERT INTO dir_zipcode(zipcode) VALUES('$input_zip')";
//                                                         ^          ^

Formatting Numbers by padding with leading zeros in SQL Server

Change the number 6 to whatever your total length needs to be:

SELECT REPLICATE('0',6-LEN(EmployeeId)) + EmployeeId

If the column is an INT, you can use RTRIM to implicitly convert it to a VARCHAR

SELECT REPLICATE('0',6-LEN(RTRIM(EmployeeId))) + RTRIM(EmployeeId)

And the code to remove these 0s and get back the 'real' number:

SELECT RIGHT(EmployeeId,(LEN(EmployeeId) - PATINDEX('%[^0]%',EmployeeId)) + 1)

How to random a zero leading string field mysql

Like @B-and-P describes in his comment. You can do this using LPAD.

UPDATE 
    customer_db
SET
    number = LPAD(FLOOR(number + rand()*1000000),10,0)

LPAD uses 3 parameters; string, total amount of characters and last but not least which character should be used for padding.
