示例1: initTable
TEST_F(TupleSchemaTest, CreateEvictedTupleSchema) {
initTable(true);
// Create the TupleSchema for our evicted tuple tables
// The first columns should be all of the columns of our primary key index
TupleSchema *evictedSchema = TupleSchema::createEvictedTupleSchema();
// fprintf(stdout, "\nEVICTED TABLE SCHEMA\n%s\n", evictedSchema->debug().c_str());
ASSERT_EQ(2, evictedSchema->columnCount());
ASSERT_EQ(VALUE_TYPE_SMALLINT, evictedSchema->columnType(0));
ASSERT_EQ(VALUE_TYPE_INTEGER, evictedSchema->columnType(1));
TupleSchema::freeTupleSchema(evictedSchema);
}示例2: initTable
TEST_F(TupleSchemaTest, CreateEvictedTupleSchema) {
initTable(true);
// Create the TupleSchema for our evicted tuple tables
// The first columns should be all of the columns of our primary key index
TupleSchema *evictedSchema = TupleSchema::createEvictedTupleSchema(m_primaryKeyIndexSchema);
// fprintf(stdout, "\nEVICTED TABLE SCHEMA\n%s\n", evictedSchema->debug().c_str());
ASSERT_EQ(m_numPrimaryKeyCols+1, evictedSchema->columnCount());
for (int i = 0; i < m_numPrimaryKeyCols; i++) {

ASSERT_EQ(m_primaryKeyIndexSchema->columnLength(i), evictedSchema->columnLength(i));
ASSERT_EQ(m_primaryKeyIndexSchema->columnAllowNull(i), evictedSchema->columnAllowNull(i));

// Then there should only be one more column that contains the 16-bit block ids
ASSERT_EQ(VALUE_TYPE_SMALLINT, evictedSchema->columnType(m_numPrimaryKeyCols));
