Need code for updating second record to first record in shell scripting
Hi,,
I have requirement that i need to get DISTINCT values from a table and if there are two records i need to update it to one record and then need to submit INSERT statements by using the updated value as a parameter. Here is the example follows..
Result as follows
Above statement always displays 1 or 2 records.If the above query returns 2 rows then i need to update it to 1 row like below
And then i need to execute INSERT statements by using ID as a parameter.
whenever i use ${ID} it should be place with the updated value 1.
insert into <TABLE>values ();
For the above requirement, i need to implement it in shell scripting and i am using nzsql.
Thanks in advance.
Cheers,
Samah

UPDATE(7) SQL Commands UPDATE(7)NAME
UPDATE - update rows of a table
SYNOPSIS
UPDATE [ ONLY ] table SET col = expression [, ...]
[ FROM fromlist ]
[ WHERE condition ]
INPUTS
table The name (optionally schema-qualified) of an existing table. If ONLY is specified, only that table is updated. If ONLY is not speci-
fied, the table and all its descendant tables (if any) are updated. * can be appended to the table name to indicate that descendant
tables are to be scanned, but in the current version, this is the default behavior. (In releases before 7.1, ONLY was the default
behavior.) The default can be altered by changing the SQL_INHERITANCE configuration option.
column The name of a column in table.
expression
A valid expression or value to assign to column.
fromlist
A PostgreSQL non-standard extension to allow columns from other tables to appear in the WHERE condition.
condition
Refer to the SELECT statement for a further description of the WHERE clause.
OUTPUTS
UPDATE #
Message returned if successful. The # means the number of rows updated. If # is 0 no rows are updated.
DESCRIPTION
UPDATE changes the values of the columns specified for all rows which satisfy condition. Only the columns to be modified need appear as
columns in the statement.
Array references use the same syntax found in SELECT [select(7)]. That is, either single array elements, a range of array elements or the
entire array may be replaced with a single query.
You must have write access to the table in order to modify it, as well as read access to any table whose values are mentioned in the WHERE
condition.
By default UPDATE will update tuples in the table specified and all its sub-tables. If you wish to only update the specific table men-
tioned, you should use the ONLY clause.
USAGE
Change word Drama with Dramatic on column kind:
UPDATE films
SET kind = 'Dramatic'
WHERE kind = 'Drama';
SELECT *
FROM films
WHERE kind = 'Dramatic' OR kind = 'Drama';
code | title | did | date_prod | kind | len
-------+---------------+-----+------------+----------+-------
BL101 | The Third Man | 101 | 1949-12-23 | Dramatic | 01:44
P_302 | Becket | 103 | 1964-02-03 | Dramatic | 02:28
M_401 | War and Peace | 104 | 1967-02-12 | Dramatic | 05:57
T_601 | Yojimbo | 106 | 1961-06-16 | Dramatic | 01:50
DA101 | Das Boot | 110 | 1981-11-11 | Dramatic | 02:29
COMPATIBILITY
SQL92
SQL92 defines a different syntax for the positioned UPDATE statement:
UPDATE table SET column = expression [, ...]
WHERE CURRENT OF cursor
where cursor identifies an open cursor.
