SQL Offers a host of powerful scalar functions. Nearly every one of these functions can be "wrapped" in an RPGLE subprocedure.
Using an SQL Scalar Function can be a lot easier than the RPG alternative:
The SQLSCALAR service program contains subprocedure wrappers for the SQL scalar functions ABS, ACOS, ANTILOG, ASCII, ASIN, ATAN, ATAN2, ATANH, BIT_LENGTH, CEIL, CHR, COALESCE, COS, COSH, COT, DATABASE, DAYNAME, DAYOFWEEK, DAYOFWEEK_ISO, DAYOFYEAR, DECRYPT_CHAR, DEGREES, DIFFERENCE, ENCRYPT_AES, ENCRYPT_RC2, ENCRYPT_TDES, EXP, FLOOR, GETHINT, HEX, IFNULL, JULIAN_DAY, LAND, LAST_DAY, LCASE, LEFT, LN, LNOT, LOG10, LOR, LOWER, LPAD, MAX, MIDNIGHT_SECONDS, MIN, MONTHNAME, NEXT_DAY, PI, QUARTER, RADIANS, RAND, REGEXP_COUNT, REGEXP_INSTR, REGEXP_REPLACE, REGEXP_SUBSTR, REPLACE, RIGHT, ROUND_TIMESTAMP, RPAD, SIN, SINH, SOUNDEX, TAN, TANH, TRUNC_TIMESTAMP, TRUNCATE, UCASE, UPPER, VALUE, WEEK, WEEK_ISO and XOR.
The download is a zip file containing a save file (1.9M) of the SQLSCALAR library and a READ_ME document which contains details on how to install and use the service program.
