Create relationship
CREATE RELATIONSHIP specifies new tables and columns relationship in a Direct Query app data model.
CREATE RELATIONSHIP can only be used in a Direct Query app. It must be preceded by a section directquery section.
Syntax:
CREATE RELATIONSHIP (OUTER|INNER) JOINED] TableName, [(OUTER|INNER) JOINED] TableName ON ConditionExpression ;
Information note
If an outer|inner joined qualifier for a table is not specified then the default will be inner joined.
Information note
For TableName, you can use quoted name name references. For example, ( IDENTIFIER | LITERAL_STRING | LITERAL_FIELD | LITERAL_NUMBER)).
Examples:
CREATE RELATIONSHIP BETWEEN T1,T2 ON A = C;
CREATE RELATIONSHIP
BETWEEN OUTER JOINED T2, INNER JOINED T3
ON (D = E or (D is null and E is null));
BETWEEN OUTER JOINED T2, INNER JOINED T3
ON (D = E or (D is null and E is null));
