Left-pads a string

Result type

VARCHAR or BLOB

Syntax

LPAD (str, endlen [, padstr])

Table 1. `LPAD` Function Parameters
Parameter	Description
str	An expression of a string type
endlen	Output string length
padstr	The character or string to be used to pad the source string up to the specified length.Default is space (“`' '`”)

Left-pads a string with spaces or with a user-supplied string until a given length is reached.

This function fully supports text BLOBs of any length and character set.
If str is a BLOB, the result is a BLOB.Otherwise, the result is a VARCHAR(endlen).
If padstr is given and equal to '' (empty string), no padding takes place.
If endlen is less than the current string length, the string is truncated to endlen, even if padstr is the empty string.

Warning

When used on a BLOB, this function may need to load the entire object into memory.Although it does try to limit memory consumption, this may affect performance if huge BLOBs are involved.
