org.datanucleus.store.rdbms.sql.SQLStatement.leftOuterJoin()
Method to form a left outer join to the specified table using the provided mappings. Will be applied to all unioned statements. @param sourceTable SQLTable for the source (null implies primaryTable) @param sourceMapping Mapping in this table to join from @param target Table to join to @param targetAlias Alias for the target table (if known) @param targetMapping Mapping in the other table to join to (also defines the table to join to) @param discrimValues Any discriminator values to apply for the joined table (null if not) @param tableGrpName Name of the table group for the target (null implies a new group) @return SQLTable for the target

            sqlStmt.setClassLoaderResolver(clr);


            if (vmd != null)
            {
                // Left outer join to value table (so we allow for null values)
                SQLTable valueSqlTbl = sqlStmt.leftOuterJoin(sqlStmt.getPrimaryTable(), valueMapping,
                    valueTable, null, valueTable.getIdMapping(), null, null);


                // Select the value field(s)
                SQLStatementHelper.selectFetchPlanOfSourceClassInStatement(sqlStmt, getMappingDef,
                    ownerSM.getExecutionContext().getFetchPlan(), valueSqlTbl, vmd, 0);
