Question

At runtime, I’m getting “ORA-01008 – not all variables bound” with a SQL statement that runs fine in TOAD and in which TOAD (and I) only find one parameter.

As can be seen below, there IS only one parameter in the query. Why would Oracle think there are more than one parameters/variables and cause an exception to be thrown?

I cannot show the real sql, but here is a facsimile of it (column/table names changed):

SELECT DECODE(POSTWHEELTYPE,'0','NONE','D','NUMERIC','D','RESTRICTED NEEDLE','X','TRANSFER TO WINTER','A','ACCESS CODE') HALTYPE,      
    DECODE(VALIDATIONTYPE,'0','NONE','A','FOXPRO CODE','P','PERSONAL CODE','S','RESTRICTED') JBJTYPE,
    LAZYNUMBER,
    DISPLAYTEXT,
    MINLENGTH || '-' || MAXLENGTH LENGTH,
    NVL(INSTRUCTIONS, '<NONE>') INSTRUCTIONS
FROM
    ABC.CODELAZYS
WHERE
    BQSERVERABCID = :ABCID
    AND VALIDATIONTYPE <> '0'
ORDER BY
    LAZYNUMBER DESC

Answer 1

The problem was that I was binding the variable too late; once I moved it above the call to ExecuteReader(), it worked.
