Question

Converting LONG to CLOB

Rating7.8Very Good

I have two tables with data type Long.
Since LONG data type can't be used for search I need to make a conversion  to CLOB.
What I woulld like to do is to have a dynamic sql  where I can specify table names, fields, and output table with fields.

For instance,
using two input tables:
CREATE TABLE table_input_1
(
  table_key_1  NUMBER,
  table_value_1 LONG
)

CREATE TABLE table_input_2
(
  table_key_2  NUMBER,
  table_value_2 LONG
)

I need a procedure or package
create or replace
convert_table_data_p(table_input_1  in varchar2, table_key_1   in varchar2,  table_value_1 in varchar2,
                                table_input_2  in varchar2, table_key_2   in varchar2,  table_value_2 in varchar2,
                                table_output   in varchar2, table_key_ou in varchar2,  table_value_o in varchar2)


This procedure should have dynamic sql that :
1. creates table
CREATE TABLE table_output
(
  table_key_ou  NUMBER,
  table_value_o  CLOB
)

2. inserts and converts data from both input tables into table_output
using cursor
SELECT table_key_1,  table_value_1, table_value_2
from table_input_1, table_input_2
where
table_key_1, = table_key_2(+);

INSERT INTO table_output values (table_key_1,  (table_value_1||table_value_2)

  3. clob to varchar2
    In the 8i database, I have a table with one field as datatype "clob". In my application pl/sql code, how can I query the database table and display the content of the clob field in a "textarea".

  5. LONG VARCHAR2 COMPARISONS
    I have a query where I am trying to compare some long VARCHAR2 strings of up to 128. Using the equals sign is very slow for obvious reaons, but does oracle have any alternate functions or index's that could possible speed this up? I am going against about 200,000 records.
