header = truefalse

True means return column names in first row of the output; default is false.

valuetype = string or list(string)

The valuetype option specifies the type of the value. It may be one of the strings "auto", "blob", "float", "integer", "text", or a list of those strings. If a list, then the type of a column is specified by the corresponding element in the list; if a string, then it specifies the type of all columns. See the Database[SQLite] help page for more information about type conversion between SQLite and Maple. The default is "auto".

The FetchAll command returns all available rows from the prepared statement.

There is no need to call Step after preparing the statement as FetchAll command will perform this.
