Hi,
If connection.getMetaData.supportsTransactions is false, we need to disallow
setAutoCommit and give appropriate exception?
Using hsqldb in mem connection with calcite Jdbc adapter, I did the following
test:
final String url = "jdbc:hsqldb:mem:.";
Properties info = new Properties();
info.put("model",
"inline:"
+ "{\n"
+ " version: '1.0',\n"
+ " defaultSchema: 'BASEJDBC',\n"
+ " schemas: [\n"
+ " {\n"
+ " type: 'jdbc',\n"
+ " name: 'BASEJDBC',\n"
+ " jdbcDriver: '" + org.hsqldb.jdbcDriver.class.getName() +
"',\n"
+ " jdbcUrl: '" + url + "',\n"
+ " jdbcCatalog: null,\n"
+ " jdbcSchema: null\n"
+ " }\n"
+ " ]\n"
+ "}");
final Connection connection = DriverManager.getConnection("jdbc:calcite:",
info);
System.out.println("connection.getMetaData.supportsTransactions: " +
connection.getMetaData().supportsTransactions());
System.out.println("connection.getAutoCommit before: " +
connection.getAutoCommit());
connection.setAutoCommit(true);
System.out.println("connection.getAutoCommit after: " +
connection.getAutoCommit());
Result in console:
connection.getMetaData.supportsTransactions: false
connection.getAutoCommit before: false
connection.getAutoCommit after: true
