select * from yourtable order by to_number(regexp_replace(yourcharacterfield,'[^0-9]'));

<div>
is there way to select it as a number rather than having to order by?

I tried the following but it doesn't work.<br />
select regexp_subst(SAMPLE_NO,'^[<wbr />0-9]+') from Table<br />
Thanks.

select regexp_subst(SAMPLE_NO,'^[0-9]+') from Table
Thanks.

<div>
put either of the conditions I used in the order by<br />
<br />
select to_number(regexp_substr(yo<wbr />urcharacte<wbr />rfield,'^[<wbr />0-9]+')) from yourtable<br />
<br />
will return '123abc' &nbsp;as 123<br />
<br />
<br />
<br />
when you say &quot;doesn't work&quot; &nbsp;- what doesn't work about it?<br />
<br />
wrong results, error, no results, keyboard catches fire?

select to_number(regexp_substr(yourcharacterfield,'^[0-9]+')) from yourtable

will return '123abc'  as 123



when you say "doesn't work"  - what doesn't work about it?

wrong results, error, no results, keyboard catches fire?

I have a column in my database that has data that begins with numbers but can have letters, that is why it is a varchar field. &nbsp;For example, 1, 1a, 2, 2a, 3, 3a, 4,5,6, 7, 8, 9 10<br />
I need to sort it in ascending order, but it sorts like the following:<br />
1<br />
10<br />
2<br />
20<br />
3<br />
30<br />
<br />
How can I get it to do that.????<br />
Thank you.

Oracle SQL character data need sorted numerically

Oracle is an object-relational database management system. It supports a large number of languages and application development frameworks. Its primary languages are SQL, PL/SQL and Java, but it also includes support for C and C++. Oracle also has its own enterprise modules and application server software.

Oracle Database

SQL (Structured Query Language) is designed to be used in conjunction with relational database products as of a means of working with sets of data. SQL consists of data definition, data manipulation, and procedural elements. Its scope includes data insert, query, update and delete, schema creation and modification, and data access control.
