Hello:
I have a table with two of the fiedls that are tables_names. I need to use then to select some data and insert in another table. The error is the following:
Procedure created.
No errors.

Can some body help me? Thanks in advanceRemove "into v_tablename,v_tablekey" where you are parsing the sql. You are already defining the columns, hence dont need the into clause.
Here is the correct stmt :
DBMS_SQL.PARSE(cursor1, 'SELECT table_name, table_key FROM ' || source, DBMS_SQL.native);

Remove "into v_tablename,v_tablekey" where you are parsing the sql. You are already defining the columns, hence dont need the into clause.
Here is the correct stmt :
DBMS_SQL.PARSE(cursor1, 'SELECT table_name, table_key FROM ' || source, DBMS_SQL.native);
Thank you for the answer but this is not the problem, I already change us you indicate and continues the same error. The error is with the two variables that i'm using for the second select.|||You have v_tablekey and v_tablename inside quotes. Change it as below :
strsql := ' SELECT DISTINCT '
|| ' l.bill_fccid '
|| ' l.name'
|| ' count(l.svcing_st) '
|| ' from '|| v_tablekey || ' l '
|| ' , '|| v_tablename || ' m '
|| ' where '
|| 'l.bill_fccid'
|| ' = '
|| 'm.bill_fccid'
|| 'group by '
|| ' l.bill_fccid'
|| 'l.name';
Also as a humble suggestion, try to form the string in fewer lines so that it will make easy for you to read & debug
