Converts a standard dimensional array to an LRS dimensional array by creating a measure dimension.
Parameters
Dimensional information array corresponding to the layer (column of geometries) to be converted, usually selected from one of the xxx_SDO_GEOM_METADATA views (described in Geometry Metadata Views).
Name of the measure dimension (M, if not otherwise specified).
Position of the measure dimension (the last SDO_DIM_ELEMENT object position in the SDO_DIM_ARRAY, if not otherwise specified).
Lower bound (SDO_LB value in the SDO_DIM_ELEMENT definition) of the ordinate in the measure dimension.
Upper bound (SDO_UB value in the SDO_DIM_ELEMENT definition) of the ordinate in the measure dimension.
Tolerance value (see Tolerance and Tolerance Values with LRS Functions). The default value is 0.00000001.
Usage Notes
This function converts a standard dimensional array to an LRS dimensional array by creating a measure dimension. Specifically, it adds an SDO_DIM_ELEMENT object at the end of the current SDO_DIM_ELEMENT objects in the SDO_DIM_ARRAY for the dimensional array (unless another dim_pos is specified), and sets the SDO_DIMNAME value in this added SDO_DIM_ELEMENT to M (unless another dim_name is specified). It sets the other values in the added SDO_DIM_ELEMENT according to the values of the upper_bound, lower_bound, and tolerance parameter values.
If dim_array already contains dimensional information, the dim_array is returned.
The _3D format of this function (SDO_LRS.CONVERT_TO_LRS_DIM_ARRAY_3D) is available. For information about _3D formats of LRS functions, see 3D Formats of LRS Functions.

Examples
The following example converts the dimensional array for the LRS_ROUTES table to LRS format. (This example uses the definitions from the example in Example of LRS Functions.)
SELECT SDO_LRS.CONVERT_TO_LRS_DIM_ARRAY(m.diminfo)
FROM user_sdo_geom_metadata m
WHERE m.table_name = 'LRS_ROUTES' AND m.column_name = 'ROUTE_GEOMETRY';
