In Oracle, you can convert number to string using the TO_CHAR() function, however, you can simply assign a numeric value to a string variable without using any function in Oracle. Below are the examples.
1. Convert Number to String using TO_CHAR() Function
PL/SQL Program
declare s_phone varchar2(100); begin s_phone := TO_CHAR(9876543210); dbms_output.put_line(s_phone); end;
Output:
9876543210
Convert in currency format:
declare s_dollar varchar2(100); begin s_dollar := TO_CHAR(1234, '$999999.99'); dbms_output.put_line(s_dollar); end;
Output:
$1234.00
2. Directly assign a Number to a String (Varchar2) Variable
declare s_pincode varchar2(100); begin s_pincode := 123456789; dbms_output.put_line(s_pincode); end;
Output:
123456789
3. Get Number into String (Varchar2) Variable using SQL Query
declare s_amount varchar2(100); begin select 98765.99 into s_amount from dual; dbms_output.put_line(s_amount); end;
Output:
98765.99
4. Convert Number to String using TO_CHAR() Function in SQL
declare s_amount varchar2(100); begin select to_char(98765.99, '$99999999.99') into s_amount from dual; dbms_output.put_line(s_amount); end;
Output:
$98765.99
