使用下面的oracle spatial函数可以查询srid 对应的EPSG代码

SDO_CS.MAP_ORACLE_SRID_TO_EPSG

Format

SDO_CS.MAP_ORACLE_SRID_TO_EPSG(

legacy_srid IN NUMBER) RETURN NUMBER;

Description

Returns the EPSG SRID value corresponding to the specified Oracle Spatial SRID value.

Parameters

legacy_srid

Oracle Spatial SRID value. Must match a value in the LEGACY_CODE column of the SDO_COORD_REF_SYS table (see Section

6.7.9).

Usage Notes

This function returns the SRID of an EPSG coordinate reference system. The EPSG SRID value for a coordinate reference system is indicated in the COORD_REF_SYS_CODE field in the EPSG Coordinate Reference System table.

To return the Oracle Spatial SRID value corresponding to a specified EPSG SRID value, use the SDO_CS.MAP_EPSG_SRID_TO_ORACLE function.

Examples

The following example returns the EPSG SRID value corresponding to Oracle Spatial SRID 82361.

SELECT SDO_CS.MAP_ORACLE_SRID_TO_EPSG(82361) FROM DUAL;

SDO_CS.MAP_ORACLE_SRID_TO_EPSG(82361)
