Re: DBI place holder for sub query problem

The DBI handles the quoting on it's own (the reason you use the place holders)... Perhaps this'll work better?

$sth=$dbh->prepare("Update Customers set RESULTS =? where rec_no=?");

Re^2: DBI place holder for sub query problem by Anonymous Monk on Jan 02, 2008 at 16:52 UTC
Thank you for your input, but when I tried it I get `DBD::Oracle::st execute failed: ORA-01722: invalid number (DBD ERROR: +error possibly near <> indicator at char 30 in 'Update Customers set + RESULTS =:<>p1....` [download] is this because it is a sql string and not a number. The sqlstring, when executed alone returns a number. TIA	[reply] [d/l]

If you are using a sub-query then the parenthesis are needed. Just omit the single quotes. `$sth=$dbh->prepare("Update Customers set RESULTS = (?) where rec_no = +?");` [download] From the error message, it seems like you are assigning RESULTS with something like SELECT.	[reply] [d/l]

If it's not a bind variable then it's not a bind variable. The bind vars get meta-quoted automagically, sql probably should not be, so I don't think you can use a bind variable to do that job. -Paul	[reply]
