Hi, We have a problem with lower() function working differently for two
different data types
table: yuva_test
column_name data_type
yt_name1 varchar(255)
yt_name2 char(1)
The data is
yt_name1 yt_name2
yuva F
bharat F
1234556 F
234 F
etc.
When we run the query "select * from yuva_test
lower(yt_name1)=lower('1234556') and lower(yt_name2)=lower('F')" it takes
forever to return, but if try "select * from yuva_test yt_name1='1234556'
and lower(yt_name2)=lower('F')" it returns immediately.
What is happenning here? Why lower behaving differently for varchar(255) and
char(1), and how to make first query to work without changing schema.
Thanks
Yuva
