Adds an ODBC layer to a map.
AddODBCLayer(string map_name, string layer_name, string service_name, string db_layer_name, string schema_name, array options)
Argument |
Contents |
map_name |
The name of the map to which the layer is added |
layer_name |
The desired name for the layer in the map |
service_name |
The name of the ODBC service |
db_layer_name |
The name of the ODBC table |
schema_name |
The name of the ODBC schema if necessary, otherwise null |
Option |

Fields |
3 strings |
The names of the fields with the ID, X and Y values (required) |
Read Only |
Boolean |
"True" to open read only, "False" (default) otherwise |
NAD Conversion |
3 strings |
Input datum, output datum, and conversion file (if needed); the input and output datums should be different |
Projection |
String, array |
The projection name and the array of options |
Transform |
Array |
Array indicating the transformation to apply to coordinates in the file. This can have three forms: 1. An array of two or more four-element arrays containing local and world coordinates for control points, for example, {{real localX1, real localY1, real longitude1, real latitude1}, ...} 2. An array of four elements - {real X_multiplier, real Y_multiplier, real X_offset, real Y_offset} 3. Center and Extent transform {c1_x, c1_y, width_1, c2_x, c2_y, width_2} where center is shifted from (c1_x,c1_y) to (c2_x,c2_y), and vector of length width_1 out of c_1 becomes a vector of length width_2 out of c_2. |
A string indicating the actual name of the layer, which is identical to layer_name unless the layer name is already in use.
The Fields option is required.
If the coordinates are longitude and latitude with implied decimal places, you must use the Transform option to multiply them by the appropriate factor to get decimal degrees. For example, if there are six implied decimal places, multiply by .000001.
For more details on the NAD Conversion option, see Datum Conversions.
For more details on the Projection option, see Using Projections and Coordinate Systems.
