TRUNCATE

This function removes a specified number of elements (the “chop count”) from the end of a vector. The syntax is as follows:

SET vector1 = TRUNCATE (vector1, chop_count)

•

If the chop count evaluates to NULL, this function returns NULL.

•

If the chop count is negative, or exceeds the initial size of the vector, an error occurs.

•

If the vector is NULL, an error occurs.

TRUNCATE is also a TDV-supported SQL function. Refer to TRUNC, for a description.
