Detailed Description

Graph description

Table expressions.

Table class provides a built-in expression parser which is used at the time of writing these lines by the following methods:

Expression may include:

field names (in square brackets);
arithmetic operators (+ (also works for concatenation of strings), -, *, /, \ (interger division), MOD (modulo), ^ (raising to power));
comparison operators (>, <, <=, >=, <>, =);
wildcard string comparison (LIKE (case-sensitive), and ILIKE (case-insensitive), where "%" represents zero or more characters, "_" represents a single character);
logical operators (AND, OR, XOR, NOT);
logical constants (TRUE, FALSE);
string constants (e.g. "my_string_constant");
round brackets (to control order of evaluation);

The intermediate values during calculation and resulting values can be of one of the following types:

double (integers are treated as doubles as well);
string;
boolean.

The parser doesn't rely on any DBMS, therefore it doesn't support standard SQL functions, both mathematic and string. Therefore for more complex expressions a column should be added, where calculations can be made using Table.get_CellValue, Table.EditCellValue API members and programming language of your choice.

Examples:

[Area] > 100 AND [Population] < 50  -- Area and Population are field names; resulting value is boolean
[Area] / 10000 + " ha"              -- Area is a field name, " ha" - string constant, "+" - concatenation operator; 
                                    -- resulting value is string
([Pop1990] + [Pop2005])/2           -- Pop1990 and Pop2005 are field names; resulting value is double
 
[Word] LIKE "_ain"                  -- Word is a field name; matches "Pain", "Rain", but not "MAIN" or "Sprain"
[RoadName] = "Main St"              -- RoadName is a field name; only matches streets specifically named "Main St"
[RoadName] LIKE "Main %"            -- Matches streets like "Main St", "Main Ave", "Main Blvd", but not "main st"
[RoadName] ILIKE "&main%"           -- Matches streets like "Main St", "main st", "Maintenance Rd", "Charmaine Dr"

Here is code sample demonstrating how to calculate a new field as an average of 2 existing fields:

string filename = @"D:\counties.dbf";
var tbl = new Table();
if (!tbl.Open(filename))
{
    MessageBox.Show("File not found: " + filename);
}
else
{
    tbl.StartEditingTable();
 
    int fldIndex = tbl.FieldIndexByName["Pop1990"];
    int fldIndex2 = tbl.FieldIndexByName["Pop1997"];
    if (fldIndex == -1 && fldIndex2 == -1)
    {
        MessageBox.Show("Source fields aren't found.");
    }
    else
    {
        // adding a new field:
        // 2 - number of decimal places; 
        // 16 - total length (numbers are actually stored as strings inside DBF )
        int fldIndexNew = tbl.EditAddField("PopAvg", FieldType.DOUBLE_FIELD, 2, 16);
 
        for (int i = 0; i < tbl.NumRows; i++)
        {
            // it's assumed here that the source fields are numeric (either integer or double),
            // but if it's not known then a field type can be checked with Table.get_Field(fieldIndex).Type
            double val1 = Convert.ToDouble(tbl.get_CellValue(fldIndex, i));
            double val2 = Convert.ToDouble(tbl.get_CellValue(fldIndex2, i));
            tbl.EditCellValue(fldIndexNew, i, (val1 + val2)/2);
         }
        MessageBox.Show("New field is calculated.");
    }
 
    if( tbl.StopEditingTable(true))
        MessageBox.Show("Table is saved.");
}
tbl.Close();
