Resolution The option(s) to resolve this Oracle error are: Option #1 Only numeric fields or character fields that contain numeric values can be used in arithmetic operations. Make sure that all expressions evaluate to numbers. Option #2 If you are adding or subtracting from dates, make sure that you added/substracted a numeric value from the date.

of reasons. It generally happens in SQL only (during a query) not in plsql (plsql throws a ora 01722 invalid number oracle decode different exception for this error). You can see this error easily by: ops$tkyte@8i> select to_number('abc') from dual; select to_number('abc') from dual * ERROR at line 1: convert string to number in oracle ORA-01722: invalid number This error seems to creep into queries in the strangest ways. A change in the order of a predicate can make it come and go -- depending on the order of evaluation in the predicate. Consider this example: ops$tkyte@8i> https://www.techonthenet.com/oracle/errors/ora01722.php create table t ( x int, y varchar2(25) ); Table created. ops$tkyte@8i> ops$tkyte@8i> insert into t values ( 1, 'abc' ); 1 row created. ops$tkyte@8i> insert into t values ( 2, '123' ); 1 row created. ops$tkyte@8i> ops$tkyte@8i> ops$tkyte@8i> select * from t where y > 100 and x = 2; X Y ---------- ------------------------- 2 123 ops$tkyte@8i> select * from t where x = 2 and y > 100; select * from t where x = 2 and y > 100 * ERROR https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:45012348053 at line 1: ORA-01722: invalid number The first query worked since we *tend* to evaluate queries from the bottom up. We evaluated the x=2 part first and never tried to do 'abc' > 100. In the second query, the y>100 was evaluated first. Y was promoted to a number and then compared to 100. 'abc' could not be converted so ORA-1722. The only general purpose solution is to always compare like types to like types. You should either convert the column Y entirely to numbers (clean the data) or use a character string comparision (which changes the meaning of the predicate -- y > 100 is very different from y > '100' ) Reviews Write a Review ORa-01722 March 27, 2001 - 2:30 pm UTC Reviewer: Tom Petrella from Melville, NY I was getting this error and it was driving me nuts because I know everything was syntactically correct and there were no invalid numbers. Be rearranging the order of the where clause i got it to work. Thanks ! Is there a surefire way to avoid this? July 11, 2002 - 10:35 am UTC Reviewer: Adrian from Exeter England Apart from the obvious method, (i.e. Always compare like data-types), is there a sure-fire way to avoid this sort of problem happening? If I have a domain table cg_ref_codes with fields domain, low_value, high_value, abbreviation, meaning (all varchar2). If further some of my domains contain purely numeric values. Is there a way that I can not have to worry about which way
UPDATE 3.3 Other Rare Situations What causes this error?[edit] An ORA-01722 ("invalid number") error occurs when http://www.orafaq.com/wiki/ORA-01722 an attempt is made to convert a character string into a number, http://psoug.org/oraerror/ORA-01722.htm and the string cannot be converted into a valid number. Valid numbers contain the digits '0' through '9', with possibly one decimal point, a sign (+ or -) at the beginning or end of the string, or an 'E' or 'e' (if it is a floating invalid number point number in scientific notation). All other characters are forbidden. There are numerous situations where this conversion may occur. A numeric column may be the object of an INSERT or an UPDATE statement. Or, a numeric column may appear as part of a WHERE clause. It is even possible for this error to appear when there are no 01722 invalid number numeric columns appearing explicitly in the statement! Examples[edit] Here are some examples: SQL> select to_number('3434,3333.000') from dual; ERROR: ORA-01722: invalid number no rows selected The above statement throws the error message, because it has found a character, in this case, a comma and the default format for TO_NUMBER does not contain a comma. The same error can occur when you use arithmetic functions on strings: SQL> select 'abc' - 124 from dual; ERROR: ORA-01722: invalid number no rows selected The error can occur when you add dates with string values: SQL> select '01-JUN-01' - 'abc' from dual; ERROR: ORA-01722: invalid number no rows selected How to fix it[edit] The fix depends upon the exact expression which caused the problem. The following guide lists the possible SQL expressions which can give this error, with their most likely cause. When addressing this error, keep in mind that it can indicate a simple keystroke problem with the query, or a deeper problem with the query logic, or even the presence of bad data in the datab

Only numeric fields or character fields containing numeric data may be used in arithmetic functions or expressions. Only numeric fields may be added to or subtracted from dates.. Action: Check the character strings in the function or expression. Verify that they contain only numbers, a sign, a decimal point, and the character "E" or "e", then retry the operation.
