SF #910423 Anomaly with ALTER TABLE altering a column's type to VARCHAR, when determining valid length of the string.

 SQL> CREATE TABLE tab ( i INTEGER );
 SQL> INSERT INTO tab VALUES (2000000000);
 SQL> COMMIT;
 SQL> ALTER TABLE tab ALTER i TYPE VARCHAR(5);
 Statement failed, SQLCODE = -607
 unsuccessful metadata update

-New size specified for column I must be at least 11 characters. i.e., it would need potentially 10 characters for the numerals and one for the negative sign.

 SQL> ALTER TABLE tab ALTER i TYPE VARCHAR(9);

This command should fail with the same error, but it did not, which could later lead to unreadable data:

 SQL> SELECT * FROM tab;
 I
 =========
 Statement failed, SQLCODE = -413
 conversion error from string "2000000000"

Not registered There were some dialect- specific arithmetic bugs:

Dialect 1

'1.5' / '0.5' did not work
avg ('1.5') did not work
5 * '1.5' produced an INT result instead of DOUBLE PRECISION
sum ('1.5') produced a NUMERIC(15, 2) result instead of DOUBLE PRECISION
- '1.5' did not work

Dialect 3

'1.5' * '0.5' and '1.5' / '0.5' were not forbidden, but they should have been.
