Joins the Left table with right table using the Left Outer Join semantics.
The Left-side table expression to be used for join.
The Right-side table expression to be used for join.
A table which includes only rows from RightTable for which the values in the common columns specified are also present in LeftTable. The table returned will have the common columns from the left table and the other columns from both the tables.
There is no sort order guarantee for the results.
Columns being joined on must have the same data type and the same name in both tables.
The columns used in the join condition that correspond to physical columns of the data model must also have the same data lineage; two columns with the same name and different data lineage generate an error.
Strict comparison semantics are used during join. There is no type coercion; for example, 1 does not equal 1.0.
