July 11, 2005 - 7:49 am UTC Reviewer: Ravi Kumar from Delhi, India Actualy There was a blank space in the column. We faced this problem when input value is 14 digit. The ONLY things you achieve by using a string to store a number/date are: a) increased storage needs b) decreased data integrity c) slower performance d) errors not too many upsides for example a house number can be 1 1a 2 2a 2b What data type should this be. http://stackoverflow.com/questions/4486949/safe-to-number

Oracle To_number Invalid Number Ignore

they are not numbers! The third Select statement is showing the data we are going to use in our next example. How can I Avoid Being Frightened by the Horror Story I am Writing?

What you'll want to do is convert the strings to numbers in the DECODE and then use THAT result in the predicate. I changed the NLS setting from ENGLISH.CANADA to AMERICAN.AMERICAN in registry and it is working now. Verify experience!

  • That's really all I am seeking to find out.
  • When I am executing the following query, select to_number('99.50') from dual; I got Oracle error ORA-01722: invalid number If I will connect using 8i client then it is Okay.
  • v#F_ACCOUNTANT_BILLS is a complex view, but "select * v#F_ACCOUNTANT_BILLS" runs without problem returning all the columns and rows.
  • Oracle is forced to do an implicit datatype conversion of the numeric column values ***OF EVERY ROW*** in this table to a character string before doing the comparison.
  • it starts with text written by me that says: ...
  • This regex might work better: ^\-?\d*\.?\d*$ which allows negative numbers and numbers starting with ., and disallows non-numeric trailing characters.

The Oracle T-SQL group is no longer active. 01722. 00000 - "invalid Number" Sooner or later in a column defined as CHAR or VARCHAR2, but is usually used for numeric data, someone will manage to put non-numeric data into it (maybe by accident).

So can anyone see why this would be causing the ORA-01722 error? SQL Problem August 17, 2006 - 7:08 pm UTC Reviewer: David from CA Thank you Tom, I will follow up with the Explain plan statment and look into it. Is there a way to "skip" it and get 0 or NULL instead? his comment is here SELECT TO_NUMBER (dummy) FROM dual; As we did mention above the conversion to a number will be quite difficult or in other words impossible.

One way of finding the problem row would be to CREATE OR REPLACE FUNCTION my_to_number( p_str IN VARCHAR2 ) RETURN NUMBER IS BEGIN RETURN to_number( p_str ); EXCEPTION WHEN others THEN I'll post a link when his follow-up goes live. Keeping a char field to store numeric data is stupidity in my opinion too but now its too late for that. Problem is with bind variable :b1 which is declared as char[18] in the program whereas CARD_NUM in table is number(16) We have 2 types of card number 1) with 14 digit

to my little knowledge on sql, i understand that inline query could execute first and then the other..is that not so ? ( hope u hate this to hear !! ) This happens when the input value does not represent a number. Is it possible to trace such an optimization or how do you determine how oracle optimize the sql statement in the example?
