Subject: ESCAPE clause causing longer query execution time
Hello,
I have a query using LIKE with the ESCAPE clause to search for an=20
underscore '_' as a literal value. When I run the query with the ESCAPE =
clause it takes much longer then when the same query is run without the=20
ESCAPE clause. I thought maybe it was an index issue, but explain plans =
for both queries are identical. I also tried rebuilding the indexes on=20
the table, but that made no improvement. Does anyone have any=20
suggestions...I am stumped!
Time to delete row with value "EZ_COMPARE" =3D=3D> 2 min. 54 =
secs.
Time to delete row with value "EZCOMPARE" =3D=3D> 2 secs.
Thank you in advance,
