Ora 01722 Invalid Number Oracle Decode
Consulting Oracle docs offer this information regarding Oracle ORA-01722: ORA-01722 invalid number Cause: The attempted conversion of a ora-01722 invalid number to_number character string to a number failed because the character string was not a valid numeric literal. Only numeric fields or character fields containing numeric data may be used in arithmetic functions or expressions. Only numeric https://www.techonthenet.com/oracle/errors/ora01722.php 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. To exhibit how Oracle ORA-01722 is often thrown, this query is given as an example: SELECT * http://www.dba-oracle.com/sf_ora_01722_invalid_number.htm 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 a specific valid number when a user attempted to convert a character string. There are several possible resolutions to Oracle ORA-01722 in this context: If you are attempting an " INSERT INTO ... VALUES (...
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 http://www.orafaq.com/wiki/ORA-01722 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 point number http://geekswithblogs.net/malisancube/archive/2008/07/25/oracle-data-conversion-ora-01722-invalid-number.aspx 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 invalid number of a WHERE clause. It is even possible for this 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 01722 invalid number 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 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 iden

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 v
