Query to remove decimal point

Question

Hi all,
I have a table A, in which there is a column currency with integer values having decimal point, i have to just remove the decimal and keep the number as it is.
Ex:- A number 23.45 should be 2345
A number 17.9 should be 179
I have to do this for all the currency values of the table A.
Can someone kindly help me with a query.
regards,

Thank you all for replying,
The problem is that there are different rows in table A, i.e many values, so i think we would have to pass this value as variable in runtime.Sorry, I don't understand.
What value do you think you have to pass as a variable? The decimal point character ('.' in America, ',' in Germany)? The number of decimal places? Some value, such as 175?
select to_number(replace (1.23, '.')) from dual;
or
SELECT REPLACE (crncy, '.') AS crncy_w_o_dot
FROM table_x;
how can i use the above query like a loopAny query is like a loop; it finds each row, and does the same sort of thing to each one.
i.e if i have many values like below in the column currency, how can i change them all.Are you saying you have different columns that need to be transformed?
If so, the answer depends on what your data is like, what results you want, and what version of Oracle you're using..
If what you want to do is simple, and the number of columns isn't to big, the best thing is to repeat the formula for every column.
Other options are likely to be slower.
You could write a user-defined fucniton to do the transformation.
You could unpivot the table, so that all the columns to be transformed become one column. You could then pivot the results back to the original number of columns, if necessary.
17.5
23.456
89.9343
43.98121thanks again for your help,Is this your sample data? It looks like just one column. Post some sample data as CREATE TABLE and INSERT statements.
What are the results you want from that data? If you need to pass some parameter to the query, give a couple of examples of different parameters and the different results they produce given the same sample data.
Whenever you have a question, say what version of Oracle you're using.
