Now you can summarise/ concatenate or whatever over the details data without the multiplication. The solution (i used) is to number datasets lines, make a table with numbers and join the details with this table: WITH B Several different types of joins are supported by Db2 for i: inner join, left outer join, right outer join, left exception. You can retrieve and join column values from two or more tables into a single row. VALUES (1, 'detail c head 1'), (1, 'detailc c head 2') To form a row of the result table, you might want to retrieve some column values from one table and some column values from another table. VALUES (1, 'detail B head 1'), (2, 'detail B head 2') If you want to use several datasets for one tablix you will face a multiplication problem: SELECT * Let's start from the ssrs grouping definition Understanding Groups (Report Builder and SSRS): All groups in a data region specify different views of the same report dataset. The result includes unmatched rows from only the table that is specified before the LEFT OUTER JOIN clause. Joins with the into part of the clause corresponds to a. A left outer join is a method of combining tables. On the other hand, every expression using the query syntax has a straight forward translation. Then just analyze that expression and reproduce it. I think i understand what is he talking about (faced the problem recently). You generally could get the exact expression used from any query expression by accessing the Expression property of the query.
