ISSUE: 1597
|
|
TITLE: Error "Data type unknown" when any UDF argument is a built-in function containing a DSQL parameter reference
|
|
DESCRIPTION:
|
|
For FB 3.x - this test uses UDF from ib_udf.
|
|
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/
|
|
