How can I right pad the number with Zeros to make sure it's always 20 digits? Short answer - You shouldn't. Numbersdon't havefixed, leading zeroes. They're just numbers. BTW, whilst you can addtrailingzeroes to a numeric value, doing so results in a totally different, numeric value....

Data presentation: LPAD() can format or present data in a desired format. We can use it to align text or display numbers with leading zeros. String manipulation: LPAD() is often used to construct dynamic strings or generate values in specific formats. Syntax: LPAD(str, len, padstr) Argume...
Numbers that are not one of these lengths are interpreted as though padded with leading zeros to the closest length. Values specified as non-delimited strings are interpreted using their length as given. If the string is 8 or 14 characters long, the year is assumed to be given by the ...
To satisfy the equal-length requirement, pad the shorter value with leading zero digits or, if the longer value begins with leading zero digits and a shorter result value is acceptable, strip them: mysql> SELECT _binary X'0040' | X'0001'; +---+ | _binary X'0040' | X'0001' | +...
The ISO-8601 standard places all the information in fixed-width data strings with leading zeros where needed. When you read ISO-8601 standard information you notice immediately that everything lines up in columns. The larger values are to the left and progressively smaller values are to the ...
The problem was that the normalization removed leading zeros in a manner which caused some values to lose some of their least significant digits. We fix this by calculating the desired precision and passing the calculated value instead of changing the original value. (Bug #106272, Bug #33787914...
The field has been declared with theZEROFILLattribute, which tells the server to pad the numeric types with leading zeros in the output to fit the specified field length. BINARY_FLAG 0x0080 The field has been declared with theBINARYattribute, which tells the server to compare strings byte-for...
I wrote code that did that for years (to pad numeric fields out to a specific width by adding leading zeros) and until I upgraded to 8.3 it caused me no problems. I knew what I meant, and so did the database, and we were both happy. The argument seems to be that we shouldn't ...
