In addition, another possibility for comparing ntext or text columns from two tables is to compare the lengths of the columns with a WHERE clause, for example: WHERE DATALENGTH(p1.pr_info) = DATALENGTH(p2.pr_info)Understand nested loops joinsIf...
Oracle: Creating Joins with the USING Clause: Use the USING clause to specify the columns for the equijoin where several columns have the same names but not same data types.

Through increasingly complex examples, this workshop illustrates each of PROC SQL's clauses, with particular focus on problems difficult to solve with "traditional" SAS code. After all, PROC SQL is part of Base SAS(R) so, although you might need to learn a few new keywords to become an ...
The SQL-92 FULL OUTER JOIN operator indicates that all rows from both tables are to be included in the results, regardless of whether there is matching data in the tables.You can include a WHERE clause with a full outer join to return only the rows where there is no matching data ...
The tables or views in the FROM clause can be specified in any order with an inner join or full outer join. However, the order of tables or views specified when using either a left or right outer join is important. For more information about table ordering with left or right outer joins...

In general, the ON clause on the JOIN looks and works just like a WHERE clause on a SELECT, except that an ON clause must specify one or more relations between the two tables being joined. Also, many SQL engines support only the equality operator for joining, but some support others, li...
