rSFSW2: Simulation Framework for SOILWAT2

Reads variables/fields from the header view or from tables including sites, runs and one of the overall aggregation tables for one of the scenarios and optionally subsets rows by a where-clause

dbOut_read_variables_from_scenario(
  fname_dbOut,
  variables = NULL,
  MeanOrSD = c("Mean", "SD"),
  scenario = "Current",
  whereClause = NULL
)

`fname_dbOut`	A character string. The path to the output database.
`variables`	A vector of character strings. The (partial) names of variables/columns/fields to be read.
`MeanOrSD`	A character string. Identify which type of overall aggregated table to read.
`scenario`	A character string. This must be one of the values from the `Scenario` values from the `header` view.
`whereClause`	A character string. This must be of the structure `field_name='value'` or `NULL`
