Example 4 with FakeCapabilitiesFinder

use of org.teiid.query.optimizer.capabilities.FakeCapabilitiesFinder in project teiid by teiid.

the class TestPreparedStatementBatchedUpdate method testUpdateVarNumCmds.

/**
 * Test prepared statements that use batched updates using the same prepared
 * command with varying number of commands in the batch.
 * <p>
 * The test verifies that no errors occur when planning and executing the
 * same batched command SQL with varying number of batched command parameter
 * value sets.  For example, if the first executeBatch() call were to occur
 * with two batched commands a repeated call with only one batched command
 * should not result in an error during planning or execution.
 * <p>
 * The test also verifies that the correct SQL is pushed to the data manager
 * to verify that the parameter substitution occurred and is correct and the
 * correct number of statements made it to the data manager for the respective
 * batch command.
 * <p>
 * The batched command "UPDATE pm1.g1 SET pm1.g1.e1=?, pm1.g1.e3=? WHERE pm1.g1.e2=?"
 * will appear as:
 * <p>
 * UPDATE pm1.g1 SET pm1.g1.e1='a', pm1.g1.e3=false WHERE pm1.g1.e2=0
 * UPDATE pm1.g1 SET pm1.g1.e1=null, pm1.g1.e3=false WHERE pm1.g1.e2=1
 * <p>
 * UPDATE pm1.g1 SET pm1.g1.e1='a', pm1.g1.e3=false WHERE pm1.g1.e2=0
 * <p>
 * UPDATE pm1.g1 SET pm1.g1.e1='a', pm1.g1.e3=false WHERE pm1.g1.e2=0
 * UPDATE pm1.g1 SET pm1.g1.e1=null, pm1.g1.e3=false WHERE pm1.g1.e2=1
 * UPDATE pm1.g1 SET pm1.g1.e1='c', pm1.g1.e3=true WHERE pm1.g1.e2=4
 * UPDATE pm1.g1 SET pm1.g1.e1='b', pm1.g1.e3=true WHERE pm1.g1.e2=5
 * <p>
 * The result should be that three commands are in the plan cache and
 * no plan creation, validation, or execution errors will occur and
 * a predetermined set of queries were executed in the data manager.
 *
 * @throws Exception
