The columns in the table that Tessellate_Search returns are as follows.
| Column Name | Data Type | Description |
|---|---|---|
| out_key | DECIMAL(18,0) | A copy of the in_key input argument. The data type of out_key matches the data type of the in_key argument. |
| VARCHAR(32) | ||
| cellid | INTEGER | The INTEGER value that is returned codes for the cell number and level. The upper 28 bits identifies the cell number, and the lower four bits identifies the level. Use:cellid / 16
to derive the cell number and: cellid MOD 16
to derive the level. Cell IDs are numbered from left to right, 0 to n-1, where n = g_nx * g_ny. Cell 0 is in the lower left corner. Here is an example that shows the cell numbering of a single-level grid (of unspecified size) that contains 16 cells. |
