getResultMetadata

Returns the metadata for an expression result. You can use getResultMetadata to get the precision, scale, and datatype of an expression result. You can assign the metadata of the return value from an expression to a JExprParamMetadata object. Use the getScale, getPrecision, and getDataType object methods to retrieve the result metadata.

Use the following syntax:

objectName.getResultMetadata();

Use the following example Java code to assign the scale, precision, and datatype of the return value of myObject to variables:

JExprParamMetadata myMetadata = myObject.getResultMetadata();
int scale = myMetadata.getScale();
int prec = myMetadata.getPrecision();
int datatype = myMetadata.getDataType();

The getDataType object method returns the integer value of the datatype, as enumerated in EDataType.
