Manage your queries

• Create a query from an existing query
  The Select Query from Library page appears if you use an existing query when defining a custom term, database restriction, or query-based interactive report.
• Specify query values
  The way in which you specify values depends on the type of variable.
• Use logical and set operators
  Logical operators act on individual rows of source data tables. Set operators act on sets of cases that are retrieved by the conditions on each side of the set operator.
• View query logic
  You can view a query from the Queries page or examine a query used by a case series.
• Rename a query
  You can rename only those queries that you created.
