This parameter affects more than one Snowflake driver/connector. The MULTISTATEMENTCOUNT parameter is not part of the JDBC standard it is a Snowflake extension.
To execute multiple statements without specifying the exact number, pass a value of 0. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result (s). The default number of statements is 1 in other words, multi-statement mode is off. The topics in this section discuss how you can use each of the three statement classes to work with data in a SQL Server database. The execute method executes an SQL statement and indicates the form of the first result. SQLServerCallableStatement - (inherited from SQLServerPreparedStatement), used for running stored procedures that might contain IN parameters, OUT parameters, or both. SQLServerPreparedStatement - (inherited from SQLServerStatement), used for running compiled SQL statements that might contain IN parameters. SQLServerStatement - used for running SQL statements without parameters. The JDBC driver provides three classes for retrieving data from a SQL Server database:
Perfino see jdbc statements executed update#
The JDBC driver also supports using SQL escape sequences, update counts, automatically generated keys, and performing updates within a batch operation. The JDBC driver can be used to run SQL statements against the database, or it can be used to call stored procedures in the database, using both input and output parameters. When you ask the question Which SQL query is the slowest in my application, perfino delivers the answer together with cumulated backtraces pointing back to the business transactions that are responsible for the. Even so, each SQL statement invocation produces a non-trivial amount of trace output. This tracing method is 'relatively' lightweight compared to the J2C Mustgather and JDBC driver trace. The Microsoft JDBC Driver for SQL Server can be used to work with data in a SQL Server database in a variety of ways. Database operations like JDBC statements, or queries to mongoDB and other NoSQL databases are first class citizens in perfino. SQL statements executed via methods such as regular objects or Stored Procedures will not be traced with this trace specification.
