oracle - How to use to_number and nullif in sql-loader? -


i've had similar problem dates (combination of to_date , nullif) here : how use decode in sql-loader?

and solved nicely.

my problem numeric field in csv file can have these formats : 999,999,999.99 or dot '.' null values.

this working :

minquantity      "to_number(:minquantity, '9999999999d999999', 'nls_numeric_characters='',.''')"

or 

minquantity      nullif minquantity      = '.'

but not working when i'm trying combine both :

minquantity      "to_number(:minquantity, '9999999999d999999', 'nls_numeric_characters='',.''')  nullif :minquantity= '.'"

here error log :

record 1: rejected - error on table my_table, column minquantity. ora-00917: missing comma

how can combine these ?

your nullif condition should not inside double-quotes sql string; , needs come first. the documentation:

  • the sql string appears after other specifications given column.

  • the sql string must enclosed in double quotation marks.

...

  • the sql string evaluated after nullif or defaultif clauses, before date mask.

so should be:

minquantity nullif minquantity = '.'   "to_number(:minquantity, '9999999999d999999', 'nls_numeric_characters='',.''')"

(you can split 2 lines readability, both parts still apply `minquantity field).

in log that's reported as:

minquantity                          next     *   ,       character     null if minquantity = 0x2e(character '.')     sql string column : "to_number(:minquantity, '9999999999d999999', 'nls_numeric_characters='',.''')"

(have got nls chars right way round? treating , decimal separator, while question suggests you're using .. either work long value enclosed in double-quotes, of course).

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
