SUPPORT / SAMPLES & SAS NOTES
Problem Note 36177: Incorrect results might occur when you run a PROC SQL join with an additional WHERE clause against Teradata tables
 |  |  |  |  |
Incorrect results might be returned when you submit an SQL procedure join with an additional WHERE clause that contains the AND or the OR logical operator followed by parentheses.
In rare cases, SAS/ACCESS® Interface to Teradata misplaces parentheses in WHERE clauses that are passed to Teradata for evaluation.
For example, suppose you submit the following code:
libname tlib teradata . . .more options. . . ;
proc sql;
select a.*
from tlib.tab1 a left join
tlib.tab2 b on a.col=b.col
where a.col2=1 and (b.col2 like 'A%' OR b.col3=2);
In this case, the software translates the WHERE clause as follows, which leads to an incorrect result:
where a."col2"=1 and b."col2" like 'A%' or (b.col3=2)
