-- This example demonstrates how to use the SE_CreateSrid function -- to create a new entry in the spatial_references table, given -- the XY extent of a spatial data set. EXECUTE FUNCTION SE_CreateSrid (166, -48, 180, -34, "New Zealand: lat/lon coords"); -- SE_CreateSrid will return the srid of the newly created -- spatial_references table entry. It uses the formula: -- new_srid = MAX(srid) + 1 -- to choose a new srid. Depending on what other srids are already -- present in the spatial_references table, you may need to adjust -- the following query slightly to inspect the new entry: SELECT * FROM spatial_references WHERE srid = 1001;
