# title: 'There are <n> dependencies' error message shows the wrong count of dependent objects.
|
|
# decription:
|
|
# For FB 2.5 and 3.x - this test uses UDF from ib_udf.
|
|
#
|
|
# 24.01.2019.
|
|
# Added separate code for running on FB 3.0.x because its current STDERR now differ from old one.
|
|
#
|
|
# Added separate code for running on FB 4.0.x.
|
|
# UDF usage is deprecated in FB 4+, see: ".../doc/README.incompatibilities.3to4.txt".
|
|
# Functions div, frac, dow, sdow, getExactTimestampUTC and isLeapYear got safe replacement
|
|
# in UDR library "udf_compat", see it in folder: ../plugins/udr/
|
|

|
|
# Checked on:
|

# 2.5.9.27126: OK, 0.719s.

# NOTE. Build 4.0.0.1172 (date: 25.08.2018) raises here exception with 'UDF' instead 'Function' in STDERR.
