Maksim Zhuravkov updated IGNITE-22015:
--------------------------------------
Description:
NOT NULL constraint is ignored by UPDATE statement and it is possible to set
null value to a not null column.
{code:java}
@Test
public void test() {
sql("CREATE TABLE t (id INTEGER PRIMARY KEY, int_col INTEGER NOT NULL)");
try {
sql("INSERT INTO t VALUES(1, NULL)");
fail();
} catch (Exception e) {
System.err.println(e.getMessage());// Column 'INT_COL' does not allow
NULLs
}
sql("INSERT INTO t VALUES(1, 42)");
sql("UPDATE t SET int_col = NULL");
for (var row : sql("SELECT id, int_col FROM t")) {
System.err.println(row); // [1, null]
}
}
{code}
The same holds for am UPDATE statement inside a MERGE statement:
{code:java}
@Test
public void test2() {
sql("CREATE TABLE t1 (id INTEGER PRIMARY KEY, int_col INTEGER NOT
NULL)");
sql("CREATE TABLE t2 (id INTEGER PRIMARY KEY, int_col INTEGER NOT
NULL)");
sql("INSERT INTO t1 VALUES (1, 42)");
sql("INSERT INTO t2 VALUES (1, 42)");
sql("MERGE INTO t2 dst USING t1 src ON dst.id = src.id WHEN MATCHED
THEN UPDATE SET int_col = NULL");
for (var row : sql("SELECT id, int_col FROM t2")) {
System.err.println(row); // [1, null]
}
}
{code}
