      1. Update io.debezium.connector.sqlserver.util.TestHelper#defaultConfig by adding the following: 
        .with(SqlServerConnectorConfig.MAX_TRANSACTIONS_PER_ITERATION, 1)
      1. Run io.debezium.connector.sqlserver.SqlServerChangeTableSetIT#addColumnToTableEndOfBatch
      2. Observe the failure.

      There are a few more tests in the suite that will fail with this configuration.

There are a few more tests in the suite that will fail with this configuration.

      The issue is reproducible only if all of the following conditions are met:

      1. max.iteration.transactions is set to a non-empty value (see DBZ-3486).
      2. There's a schema change N transactions or more ahead of the current position of the connector, where N is the value of max.iteration.transactions.

      While trying to query the next batch of CDC events, the connector uses invalid SPROC parameters and fails with the following error:

      An insufficient number of arguments were supplied for the procedure or function cdc.fn_cdc_get_all_changes_ ... .
