I am trying to call a `select` query from my Java Program but i am getting `Invalid Number`error.
I am trying to call the query something like this

`code`

```
 String[] l_arr = new String[]{"CUSTOMERCUMULATIVELIMIT"};

    l_rs = JDBCEngine.executeQuery(MessageFormat.format(
                        " SELECT  LIMITS,  P.PACKAGE_ID  FROM MSTGLOBALLIMITSPACKAGE P  ,MSTCUSTOMERPROFILE C  WHERE P.PACKAGE_ID = {0}   AND C.ID_CUST = ?    AND C.ID_ENTITY = ?  AND C.TYPEUSER = ?  AND C.ID_ENTITY = P.ID_ENTITY  AND P.PACKAGE_ID NOT LIKE ?",l_arr );

```

I am getting query something like this:

`Result`

```
SELECT LIMITS, P.PACKAGE_ID
  FROM MSTGLOBALLIMITSPACKAGE P, MSTCUSTOMERPROFILE C
 WHERE P.PACKAGE_ID = CUSTOMERCUMULATIVELIMIT
   AND C.ID_CUST = '00000144'
   AND C.ID_ENTITY = 'B001'
   AND C.TYPEUSER = 'ECU'
   AND C.ID_ENTITY = P.ID_ENTITY
   AND P.PACKAGE_ID NOT LIKE '*%'

```

I am getting the error Invalid number in the line `P.PACKAGE_ID = {0}`. I gone through and come to know that if i use `to_char` i can avoid this error. But I am not sure how to use `to_char` in `P.PACKAGE_ID = {0}`.

Also `PACKAGE_ID`  is of type `Varchar2` and `CUSTOMERCUMULATIVELIMIT` is a column in `MSTCUSTOMERPROFILE` of type `Number`.

Any help or suggestion will be appreciated. Thanks.
