Question

I access to an AS400/DB2 with PHP via unixODBC
But some field name of my AS400 are named with "££.." (it can't be changed)
And when I tried to launch an sql query from my PHP page 

select * from LIBNAME.TABLE where ££FIELD like 'test%'

I always get the same error message

SQL error: [unixODBC][IBM][System i Access ODBC Driver]Invalid string or buffer length., SQL state S1090 in SQLExecDirect

If someone have clue.

Was it helpful?

Solution

Try adding this statement before the query execution:

setlocale(LC_CTYPE, 'en_US');

OTHER TIPS

DB2 should have some way of enclosing the identifiers. Some databases use double quotes

select * from "tableID" where "fieldID" like 'blah%'

mySQL uses backticks. Not sure with DB2 but shouldn't be too hard to find out and try. If that doesn't work, see if there is a way to represent characters by hex value in a string. Like 'hello\x0A\x0Dthere' would be the words 'hello' and 'there' separated by a line-break. You may just need to find the value for £.
