- | {{page>:sql_bar&nofooter&noeditbtn}} | ||
- | ===== Description ===== | ||
- | Returns a pseudo-random number. The term "pseudo-random" is used as randomization is done using the Posix rand and srand functions. While these routines do provide satisfactory randomization for most applications, the numbers generated are not entirely random. | ||
- | If seed is specified, it is used to start the random number generator. Note that only a single $random stream can be used in the process. If there are multiple $random functions in a select, only the first seed is used. Seed must be a literal. The return value is INTEGER length 4. | ||
- | ===== Syntax ===== | ||
- | $RANDOM[(seed)] | ||
- | |||
- | == (seed) == | ||
- | |||
- | Optional. Seed must be a literal. | ||
