SPACE is a string manipulation function that manipulates all data types (BIT, BLOB, and CHARACTER), and creates a string consisting of a defined number of blank spaces.
SPACE returns a character string consisting of the number of blank spaces given by NumericExpression. The parameter must be of type INTEGER; the result is of type CHARACTER.
If the parameter is negative or zero, a zero length character string is returned. If the parameter is NULL, the result is NULL.
The string is limited to 32*1024*1024 to protect the broker from erroneous programs. If this limit is exceeded, an exception condition is issued.
