| NULL | ? ] AS Datatype) The data type to which you are casting an expression is the target type. The data type of the expression from which you are casting is the source type. CAST conversions among SQL-92 data types The following table shows valid explicit conversions between source types and target types for SQL data types. This table shows which explicit conversions between data types are valid. The first column on the table lists the source data types. The first row lists the target data types. A "Y" indicates that a conversion from the source convert varchar to number in oracle to the target is valid. For example, the first cell in the second row lists the source data type SMALLINT. The remaining cells on the second row

Oracle Cast Long To Varchar2

This column holds float and int values mostly. I am trying to run a query that will grab the values, but have the value format in standard US currency format. For example, if a value is 3020 the query will return 3,020.00. I have tried the following, http://stackoverflow.com/questions/18475101/converting-string-to-formatted-number-in-oracle but neither work. SELECT TO_CHAR(Q1, '9,999.99') FROM TABLE1; ORA-01722: invalid number 01722. 00000 - "invalid number" SELECT TO_CHAR(TO_NUMBER(Q1), '9,999.99') FROM TABLE1; ORA-01722: invalid number 01722. 00000 - "invalid number" I also tried using an actual value instead of the column name, and the first example works. :-/ SELECT TO_CHAR('1234', '9,999.99') FROM TABLE1; //returns 1,234.00 After this step, I went back and tried adding a format mask to TO_NUMBER(): SELECT TO_CHAR(TO_NUMBER(Q1, '9,999.99'), '9,999.99') FROM TABLE1; ORA-01722: invalid number 01722. 00000 - "invalid number" It's still not working. Can someone explain exactly why this doesn't work for my column? Initially though it was because the datatype of the column wasn't number, float, or integer, but even after converting to number I still get the same error. Any help would be greatly appreciated. sql oracle oracle10g share|improve this question edited Sep 20 '13 at 22:07 peterm 57.6k56277 asked Aug 27 '13 at 20:43 Bad Programmer 1,44382946 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted That most likely means that you have nonnumerical values in Q1. Therefore either filter out rows with such values or substitute them (e.g. with 0.00) SELECT TO_CHAR(Q1, '9,999.99') FROM table1 WHERE REGEXP_LIKE(q1, '^[+-]?[.0-
