You've only given half the information needed. –Greg Hewgill Sep 23 '12 at 1:26 2 The telephone numbers are the only thing which might reasonably be a defined as a numeric which your data doesn't represent as a numeric (spaces aren't numeric). So: check your table definition and compare with your input statements. –APC Sep 23 '12 at 22:05 5 Why would people down vote this question. For people who are new to databases, this is a weird error. I can see how enclosing the values with quotes might make it look like it's a string. It just depends on what the database is setup as. It might all be strings or numbers just depends on the fields. Maybe it was an error when the database was created. –sisharp Jun 14 '13 at 19:59 4 I know it's been 2 years, but how about an "accept"? –Aaron Nov 27 '14 at 14:44 2 And yet another year goes by without an "accept." Although, this is my highest scoring answer, so I can't feel too b

Convert String To Number In Oracle
ORA-01722: invalid number ora-01722 invalid number to_number tips Oracle Error Tips by Burleson Consulting Oracle docs offer this information regarding Oracle ORA-01722: ORA-01722 sql error: 1722, sqlstate: 42000 invalid number Cause: The attempted conversion of a character string to a number failed because the character string was not a valid numeric literal. Only numeric fields or character fields containing numeric http://stackoverflow.com/questions/12549029/sql-error-ora-01722-invalid-number 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. Check that they contain only numbers, a sign, a decimal point, and the character "E" or "e" and retry the operation. Jonathan Gennick provides information regarding Oracle ORA-01722 in conjunction with subqueries and Oracle Optimizer. http://www.dba-oracle.com/sf_ora_01722_invalid_number.htm To exhibit how Oracle ORA-01722 is often thrown, this query is given as an example: SELECT * FROM ( SELECT FLAG, TO_NUMBER ( NUM ) NUM FROM SUBTEST WHERE FLAG = 'N' ) WHERE NUM > 0 ; Here, from in the FROM clause of a query, the user is attempting to have a subquery of the original query, which is causing Oracle ORA-01722 to be thrown. The Oracle ORA-01722 error is thrown with the failure because of the outer query. This is because it is trying to test the NUM > 0 condition first because it is assumed it might be more useful. Gennick goes on to show that Oracle ORA-01722 is thrown because the Oracle optimizer has re-written the query as: SELECT FLAG, TO_NUMBER ( NUM ) NUM FROM SUBTEST WHERE TO_NUMBER ( NUM ) > 0 AND FLAG = 'N' ; This throws Oracle ORA-01722 because the re-written query causes the system to convert a non-numeric NUM value of the WHERE clause into numbers. OraFaq also has notes on Oracle ORA-01722. Here, it is explained that Oracle ORA-01722 is thrown because a particular string was not able o be converted into
17, 2012 - 9:21 am UTC Category: � Version: Whilst you are here, check out some content from the AskTom team: My First Day with the New Release Latest Followup You Asked What is the error ORA-01722 https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:45012348053 and we said... ORA-1722 is Invalid number. We've attempted to either explicity or implicity convert a character string to a number and it is failing. This can happen for a number of reasons. It generally happens in SQL only (during a query) not in plsql (plsql throws a different exception for this error). You can see this error easily by: ops$tkyte@8i> select to_number('abc') from dual; select to_number('abc') from dual * ERROR invalid number at line 1: ORA-01722: invalid number This error seems to creep into queries in the strangest ways. A change in the order of a predicate can make it come and go -- depending on the order of evaluation in the predicate. Consider this example: ops$tkyte@8i> 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$tkyte@8i> insert into 01722 invalid number t values ( 2, '123' ); 1 row created. ops$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 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.
