AddODBCLayer()

Summary

Adds an ODBC layer to a map.

 

Syntax

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 Type Contents
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.

 

Returns

A string indicating the actual name of the layer, which is identical to layer_name unless the layer name is already in use.

 

Notes

Example

AddODBCLayer(GetMap(), "Cities", "myservice", "US City", "US Data",

{{"Fields", "ID", "Lon", "Lat"}})
