Query modifiers are query words that have special
meaning to Google. Typically these operators modify the search in some way, or
even tell Google to do a totally different type of search.
Query modifiers are used to retrieve data stored in
the archive. They are used with sampling and calculation modes to get a
specific data set. The following are the available Historian demand modifiers.
Query modifiers, also called WHERE components in
JReport, are the clauses in WHERE in SQL-select statements. Selected SQL
statements are called queries in JReport. Both query and query modifiers are
stored in the catalog and the query modifier is stored independently in the
catalog (not related to queries). When executing a report, JReport creates the
SQL statement based on the query used in the report and can replace the WHERE
clause in the SQL statement if there is a modified query modifier.
The query modifier in the catalog can be hidden in
two formats: structure and string. Groups of conditions are stored in the
structure format. The query modifier consists of multiple groups of states and
groups are connected by a logical operator. Each condition consists of many
conditions and the conditions are also linked by a logical operator. Each
condition consists of a left-hand expression, the relationship operator and a
correct expression. The query modification text is saved in the format of the
string.
