Example 5 with StoredFunctionCall

use of org.eclipse.persistence.queries.StoredFunctionCall in project eclipselink by eclipse-ee4j.

the class StoredFunctionQueryHandler method setSingleResult.

@Override
protected void setSingleResult(XRServiceAdapter xrService, StoredProcedureCall spCall, QName resultType) {
    if (isCursorType(xrService, resultType)) {
        spCall.useUnnamedCursorOutputAsResultSet();
    } else {
        StoredFunctionCall sfCall = (StoredFunctionCall) spCall;
        Class<?> clz = SCHEMA_2_CLASS.get(resultType);
        if (clz != null) {
            sfCall.setResult("", clz);
        } else {
            sfCall.setResult("", OBJECT);
        }
        DatabasePlatform platform = xrService.getORSession().getPlatform();
        if (platform == null) {
            platform = new DatabasePlatform();
        }
        // StoredFunction's return value is the first parameter
        ((DatabaseField) sfCall.getParameters().get(0)).setSqlType(platform.getJDBCType(clz));
    }
