I am Prasanna – learner and new at SQL
can you please explain that how do I takkle the problem below.

I have three tables A, B and C

A – Temperory data
B – All Raw data
C – History Data

please note that the table structure and column names are same in all three tables.
I have updated data in table A.
I already have some old data in table B.
Table C is empty.
Now I want to append the updated data (records) from table A to table B. However there may be duplicate records found while appending the data. I dont want to delete duplicate data(records) found from table B. I just want to move that records from table B to table C and append the updated data from table A to table B. The first column is Identicle in all three tables -
Note :- The first column is SO Number and there are 1000 SO number which are 5 digits number and there may be multiple records under 1 particular SO.

Please tell me the stored procedure for this.

Thanks & Regards,
Prasanna

tcl means transcational control language..?
dtl means data transcation language?
what is the difference between these two?
in tcl they told only committ and rollback.. they are not mentioned the svae point in the tcl.. but dtl they mentioned…
what is the exact difference between thes two?

1) DROP is a DDL statement in order to drop the table and database:

i) SYNTAX:

DROP TABLE TABLE_NAME;
DROP DATABASE DATABASE_NAME;

EXAMPLE:

DROP TABLE EMP_DEPARTMENT;
DROP DATABASE EMPLOYEE

ii) When we used DROP TABLE it deletes the entire table data with a structure(column names also).

iii) When we used DROP DATABASE it deletes the entire DATABASE containing a number of tables, functions, stored procedures …………………n .

2) DELETE:

i) Delete command is used to delete the data within a table and not for any database.

ii) When we use Delete command it only deletes the data within a table but keeps the structure of table as it is.

SYNTAX: DELETE TABLE_NAME

EXAMPLE:

DELETE EMPLOYEE;

(That is it kees the table name as it is)

I hope , after reading this you would be satisfied.
