is
v_sql varchar2(9000);
cursor c1(p_variable1 varchar2) is select distinct(p_variable1) from ACD_BAL_400010_DUMMY;
begin
for i in c1(src_col1)
LOOP
v_sql := 'update ' || tab1 || ' set ' || tar_col1 || ' = (select distinct(' || tar_col2 || ') from ' || tab2 || ' where ' || src_col2 || ' =i)where '||src_col1 || ' = i';
EXECUTE IMMEDIATE v_sql;----------------------ORA-00904: "I": invalid identifier
EXIT WHEN c1%NOTFOUND;

Can you'll please tell me a solution for this error "ORA-00904: "I": invalid identifier" in line number 10Why the dynamic SQL?
Not to be mean here, but since you don't seem to know how to debug your procedure and find out why it's not compiling, I'm going to assume you're relatively new to the Oracle world. Are you aware of the ramifications of abusing dynamic SQL like this?
