Function to pad out a character string to a defined length from the left
LPAD(<expC1>, <expN> [, <expC2>])
The LPAD() function right justifies a character string <expC1> and pads out the left of the string, to a total length of <expN> characters, with blank spaces. The optional <expC2> may be used to pad <expC1> with a character string instead of blank spaces. The LPAD() function is useful for creating fixed length character strings by padding out the string with blanks. If the string being processed is longer than the specified total length, the string is truncated.
The LPAD() function is synonymous with the PADL() function.
