ID: issue-2242
ISSUE: 2242
TITLE: Index is not used for some date/time expressions in dialect 1
DESCRIPTION:
JIRA: CORE-1812
FBTEST: bugs.core_1812
NOTES:
[02.02.2019] pzotov
Added separate code for FB 4.0: statements like "SELECT TIMESTAMP 'now' FROM RDB$DATABASE;" can not
be used anymore (error: SQLSTATE = 22018 / conversion error from string "now").
Details about timezone datatype see in: doc\\sql.extensions\\README.time_zone.md
[01.09.2023] pzotov
Adjusted plan for FB 4.x+ to current versions after fixed
