In Oracle/PLSQL, the lpad function pads the left-side of a string with a specific set of characters.
The syntax for the lpad function is:
lpad( stringÒ», padded_length, [ pad_string ] )
stringÒ» is the string to pad characters to (the left-hand side).
padded_length is the number of characters to return. If the padded_length is smaller than the original string, the lpad function will truncate the string to the size of padded_length.
pad_string is optional. This is the string that will be padded to the left-hand side of string1. If this parameter is omitted, the lpad function will pad spaces to the left-side of string1.
Applies To:
Oracle °Ëi, Oracle ¾Åi, Oracle Ê®g, Oracle 11g
For example:
lpad('tech', Æß); would return ' tech'
lpad('tech', ¶þ); would return 'te'
lpad('tech', °Ë, 'Áã'); would return '0000tech'
lpad('tech on the net', 15, 'z'); would return 'tech on the net'
lpad('tech on the net', 16, 'z'); would return 'ztech on the net'
