数据库查询语句求解？

Question

数据库查询语句，如下

{$translate_lookup_exclusivelbadge_history}
SELECT {$column_selection_exclusivelid, pin,name,area,type,host_xact_time}FROM {$union_exclusive | history | historytmp}
WHERE {$text__exclusive | report.Numbe | bid} AND
{$text_exclusive | report.Name | name) AND
(Stext exclusivelreport.PINumberipin) AND

{$single_choice_exclusive | report.Area |  SELECT  Id,description from area where facility IN（{ficility_set}） ORDER BY description | area} AND

(facility IN({$factility_set}) OR factility IS NULL)

求解语句大致的含义？
