SRID values must be in the range of 32-bit unsigned integers, with these restrictions:
-
SRID 0 is a valid SRID but cannot be used with DROP SPATIAL REFERENCE SYSTEM.
-
If the value is in a reserved SRID range, a warning occurs. Reserved ranges are [0, 32767] (reserved by EPSG), [60,000,000, 69,999,999] (reserved by EPSG), and [2,000,000,000, 2,147,483,647] (reserved by MySQL). EPSG stands for the European Petroleum Survey Group. - Users should not drop SRSs with SRIDs in the reserved ranges. If system-installed SRSs are dropped, the SRS definitions may be recreated for MySQL upgrades.
