createnemodb(path::String;
defaultvals::Dict{String, Float64} = Dict{String, Float64}(),
foreignkeys::Bool = false)

Creates an empty NEMO scenario database in SQLite. If the specified database already exists, drops and recreates NEMO tables in the database.

Arguments

• path::String: Full path to the scenario database, including the file name.
• defaultvals::Dict{String, Float64} = Dict{String, Float64}(): Dictionary of parameter table names and default values for val column.
• foreignkeys::Bool = false: Indicates whether to create foreign keys within the database.

dropdefaultviews(db::SQLite.DB)

Drops all views in db whose name ends with ""_def"".

dropresulttables(db::SQLite.DB, quiet::Bool = true)

Drops all tables in db whose name begins with ""v"" or ""sqlite_stat"" (both case-sensitive). The quiet parameter determines whether most status messages are suppressed.

logmsg(msg::String, suppress=false, dtm=now()::DateTime)

Prints a log message (msg) to STDOUT. The message is suppressed if suppress == true. dtm determines the date and time included in the printed message.

Examples

julia> using Dates

julia> logmsg("Test message", false, DateTime(2020))
2020-01-Jan 00:00:00.000 Test message

setparamdefault(db::SQLite.DB, table::String, val::Float64)

Sets the default value for a parameter table in a NEMO scenario database.

Arguments

• db::SQLite.DB: Scenario database containing the parameter table.
• table::String: Table name (case-sensitive).
• val::Float64: Parameter value (must be a floating-point number).

    writefilename::String = "nemomodel.bz2",
    writefileformat::MathOptInterface.FileFormats.FileFormat = MathOptInterface.FileFormats.FORMAT_MPS
)

Writes a file representing the optimization problem for a NEMO scenario. Returns the name of the file. All arguments except writefilename and writefileformat function as in calculatescenario. writefilename and writefileformat are described below.

Arguments

• writefilename::String: Name of the output file. If a path is not included in the name, the file is written to the Julia working directory. If the name ends in .gz, the file is compressed with Gzip. If the name ends in .bz2, the file is compressed with BZip2.
• writefileformat::MathOptInterface.FileFormats.FileFormat: Data format used in the output file. Common formats include MathOptInterface.FileFormats.FORMAT_MPS (MPS format) and MathOptInterface.FileFormats.FORMAT_LP (LP format). See the documentation for MathOptInterface for additional options.
