INSERT INTO CUSTOMER VALUES (1,'MALADY','Claire','27 Smith St Caulfield','0419 853 694'); INSERT INTO CUSTOMER VALUES (2,'GIBSON','Jake','27 Smith St Caulfield','0415 713 598'); INSERT INTO CUSTOMER VALUES (3,'LUU','Barry','5 Jones St Malvern','0413 591 341'); INSERT INTO CUSTOMER VALUES (4,'JONES','Michael','7 Smith St convert string to number in oracle Caulfield','0419 853 694'); INSERT INTO CUSTOMER VALUES (5,'MALADY','Betty','27 Smith St Knox','0418 418 347'); sql oracle plsql share|improve this question edited Sep 23 '12 at 6:44 a_horse_with_no_name 187k24235312 asked Sep 23 '12 at 1:24 Phillip Gibson 244133 19 So... what's the table definition for CUSTOMER? 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 abo
17, 2012 - 9:21 am UTC Category: � Version: Whilst you are here, check out some content from the AskTom team: Index compression working out the ora-01722 invalid number to_number compression number Latest Followup You Asked What is the error ORA-01722 and ora 01722 invalid number oracle decode we said... ORA-1722 is Invalid number. We've attempted to either explicity or implicity convert a character string to a ora 01722 invalid number while upgrade 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 http://stackoverflow.com/questions/12549029/sql-error-ora-01722-invalid-number for this error). You can see this error easily by: ops$tkyte@8i> select to_number('abc') from dual; select to_number('abc') from dual * ERROR at line 1: ORA-01722: invalid number This error seems to creep into queries in the strangest ways. A change in the order of a predicate can make it come and go -- depending on the order of evaluation in the predicate. https://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:45012348053 Consider this example: ops$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$tkyte@8i> insert into t values ( 2, '123' ); 1 row created. ops$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 c
UPDATE 3.3 Other Rare Situations What causes this error?[edit] An ORA-01722 ("invalid number") error occurs when an attempt is made to convert a character string into a number, and the string cannot be converted into a valid number. Valid numbers contain http://www.orafaq.com/wiki/ORA-01722 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 point number in scientific notation). All other characters are http://geekswithblogs.net/malisancube/archive/2008/07/25/oracle-data-conversion-ora-01722-invalid-number.aspx 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 invalid number error to appear when there are no 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 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 database itself. When doing an INSERT INTO ... VALUES (...)[edit] One of the data items you are trying to insert is an invalid number. Locate and correct it. If all of the numbers appear to be valid, then you probably have your columns out of order, and an item in the VALUES clause is being inserted into a NUMBER column instead of the expected VARCHAR2 column. This can happen when a table has columns added or removed. You are doing an INSERT or UPDATE, with a sub query supplying the values. Obviously, the preceding considerations apply here as well. What makes this more complicated is that the offending character string is hidden as a row in a table. The fix is to identify the row (or rows) which has the non-numeric string, and either change the data (if it is in error) or add something to the sub query to avoid selecting i

I’m using Oracle 9i and I have been trying to extract numeric data out of a list of data items, so I created a UDF (User Defined Function) and called it IsNumeric. I faced a serious problem when I wanted to use comparison operators. My data was as follows COL1 COL2 1 12 2 Absent 3 5 4 7 Days 5 7 6 Six Days 7 8 Un Aavalable 9 6 To create the scenario, follow the steps below. 1. Create the Test1 table. And executed the following command create table test1( col1 numeric(5) primary key, col2 varchar(20) ) 2. Insert data into the table. insert into test1 values (1, '12'); insert into test1 values (2, 'Absent'); insert into test1 values (3, '5'); insert into test1 values (4, '7 Days'); insert into test1 values (5, '7'); insert into test1 values (6, 'Six Days'); insert into test1 values (7, ''); insert into test1 values (8, 'Un Avalable'); insert into test1 values (9, '6'); 3. Create a user defined function. create or replace function isnumeric(v in varchar2) return number as -- returns 1 if the parameter is numeric -- 0 non numeric num number; begin num := to_number(v); return 1; exception when others then return 0; end; 3. Enter your select statement. select * from test1 where isnumeric(col2) = 1 and col2 > 5 You will get the
