ISSUE: 6135
|
|
TITLE: Provide name of udf function for "arithmetic exception, numeric overflow, or string truncation"
|
|
DESCRIPTION:
|
|
*** FOR FB 3.X ONLY ***
|
|
Test uses UDF 'sright' declared in ib_udf.sql script which for sure present in every FB snapshot.
|
|
After this, we try to create PSQL function with the same signature.
|
|
|
|
*** FOR FB 4.X AND ABOVE ***
|
|
Added separate code for running on FB 4.0.x: use udf_compat!UC_div from UDR engine.
|
|
It seems that this UDR function is the only wich we can force to raise exception by passing invalid
|
|
argument #2 that will cause zero divide.
|
|
|
|
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/
