Specifically, it does not return a "no such column" # or "no such table" error if the table or column in question does exist # but was added after the second client loaded its cache of the database # schema. # # Types of schema modifications: # # 1. Adding a database table. # 2. Adding a database view. # 3. Adding a database index. # 4. Adding a database trigger. # 5. Adding a column to an existing table (ALTER TABLE). # do_multiclient_test tn { # Have connections [db1] and [db2] load the current database schema. # sql1 { SELECT * FROM sqlite_master } sql2 { SELECT * FROM sqlite_master } foreach {tn2 c1 c2} { 1 { CREATE TABLE t1(a, b) } { SELECT * FROM t1 } 2 { CREATE TABLE t2(a, b) } { UPDATE t2 SET a = b } 3 { CREATE TABLE t3(a, b) } { DELETE FROM t3 } 4 { CREATE TABLE t4(a, b) } { INSERT INTO t4 VALUES(1, 2) } 5 { CREATE TABLE t5(a, b) } { DROP TABLE t5 } 6 { CREATE TABLE t6(a, b) } { CREATE INDEX i1 ON t6(a) } 7 { ALTER TABLE t1 ADD COLUMN c } { SELECT a, b, c FROM t1 } 8 { ALTER TABLE t2 ADD COLUMN c } { UPDATE t2 SET a = c } 9 { ALTER TABLE t2 ADD COLUMN d } { UPDATE t2 SET d = c } 10 { ALTER TABLE t3 ADD COLUMN c } { DELETE FROM t3 WHERE c>10 } 11 { ALTER TABLE t4 ADD COLUMN c } { INSERT INTO t4(a,b,c) VALUES(1,2,3) } 12 { ALTER TABLE t6 ADD COLUMN c } { CREATE INDEX i2 ON t6(c) } 13 { ALTER TABLE t6 ADD COLUMN d } { CREATE TRIGGER tr1 AFTER UPDATE OF d ON t6 BEGIN SELECT 1, 2, 3; END; } 14 { CREATE INDEX i3 ON t1(a) } { DROP INDEX i3 } 15 { CREATE INDEX i4 ON t2(a) } { SELECT * FROM t2 INDEXED BY i4 ORDER BY a } 16 { CREATE TRIGGER tr2 AFTER INSERT ON t3 BEGIN SELECT 1 ; END } { DROP TRIGGER tr2 } 17 { CREATE VIEW v1 AS SELECT * FROM t1 } { SELECT a,b,c FROM v1 } 18 { ALTER TABLE t1 ADD COLUMN d } { SELECT a,b,c,d FROM v1 } 19 { CREATE TABLE t7(a, b) } { DROP TABLE IF EXISTS t7; CREATE TABLE t7(c, d); } 20 { CREATE INDEX i5 ON t7(c, d) } { DROP INDEX IF EXISTS i5; CREATE INDEX i5 ON t7(c) } 21 { CREATE TRIGGER tr3 BEFORE DELETE ON t7 BEGIN SELECT 1, 2, 3 ; END } { DROP TRIGGER IF EXISTS tr3; CREATE TRIGGER tr3 AFTER INSERT ON t7 BEGIN SELECT 1, 2, 3 ; END } 22 { CREATE TABLE t8(a, b) } { CREATE TRIGGER tr4 AFTER UPDATE OF a ON t8 BEGIN SELECT 1, 2, 3; END; } } { do_test schema3-1.$tn.$tn2 { sql1 $c1 sql2 $c2 } {} } } finish_test
