Hi,I have a situation where I need a number to be represented as a string in a place holder: my $x = 7553; $dbh->do("SELECT * FROM PRODUCTS WHERE VENDOR = ?", {}, $x); I'd like the above to be the same as: SELECT * FROM PRODUCTS WHERE VENDOR = '7553' The VENDOR column is a VARCHAR2, and Oracle won't use the index on that column unless it is specified as a string. However, it doesn't complain if VENDOR = 7553 is used. See this link for more background info: http://forums.oracle.com/forums/thread.jspa?messageID=3451942 Is there a way to ensure that the parameter is passed to Oracle as a string?
You do not say which perl driver your are using to talk to Oracle. The DBD::Oracle driver binds all placeholders as strings by default. Are you using DBD::Oracle? -- Charles Jardine - Computing Service, University of Cambridge c...@cam.ac.uk Tel: +44 1223 334506, Fax: +44 1223 334679
