Rick Hillegas updated DERBY-3570:
---------------------------------
Attachment: derby-3570-02-aa-grammar.diff
Attaching derby-3570-02-aa-grammar.diff. This patch adds the DETERMINISTIC
clause to the CREATE FUNCTION/PROCEDURE statements. Touches the following files:
M java/engine/org/apache/derby/impl/sql/compile/sqlgrammar.jj
Adds a new non-reserved keyword, DETERMINISTIC. Adds new clauses to the CREATE
FUNCTION/PROCEDURE statements.
M java/engine/org/apache/derby/catalog/types/RoutineAliasInfo.java
Changes the toString() method to emit a DETERMINISTIC clause when the routine
is deterministic. This, in turn, causes the dblook output to faithfully
reproduce the DDL for deterministic routines.
M
java/testing/org/apache/derbyTesting/functionTests/tests/lang/GeneratedColumnsTest.java
Adds positive and negative tests for the new DDL.
M
java/testing/org/apache/derbyTesting/functionTests/tests/upgradeTests/Changes10_5.java
Verifies that the new clauses are recognized only after hard upgrade to 10.5.
M
java/testing/org/apache/derbyTesting/functionTests/tests/tools/dblook_makeDB.sql
Adds routines with DETERMINISTIC and NOT DETERMINISTIC clauses to verify that
dblook faithfully emits DDL for these routines.
M
java/testing/org/apache/derbyTesting/functionTests/master/DerbyNet/dblook_test_net.out
M
java/testing/org/apache/derbyTesting/functionTests/master/DerbyNet/dblook_test_net_territory.out
