All Implemented Interfaces:
ISQLServerConnection, Serializable, AutoCloseable, Connection, Wrapper
Direct Known Subclasses:
SQLServerConnection43
public class SQLServerConnection extends Object implements ISQLServerConnection, Serializable
Provides an implementation java.sql.connection interface that assists creating a JDBC connection to SQL Server. SQLServerConnections support JDBC connection pooling and may be either physical JDBC connections or logical JDBC connections. SQLServerConnection manages transaction control for all statements that were created from it. SQLServerConnection may participate in XA distributed transactions managed via an XAResource adapter. SQLServerConnection instantiates a new TDSChannel object for use by itself and all statement objects that are created under this connection. SQLServerConnection manages a pool of prepared statement handles. Prepared statements are prepared once and typically executed many times with different data values for their parameters. Prepared statements are also maintained across logical (pooled) connection closes. SQLServerConnection is not thread safe, however multiple statements created from a single connection can be processing simultaneously in concurrent threads. This class's public functions need to be kept identical to the SQLServerConnectionPoolProxy's. The API javadoc for JDBC API methods that this class implements are not repeated here. Please see Sun's JDBC API interfaces javadoc for those details. NOTE: All the public functions in this class also need to be defined in SQLServerConnectionPoolProxy Declare all new custom (non-static) Public APIs in ISQLServerConnection interface such that they can also be implemented by SQLServerConnectionPoolProxy

    • prepareStatement

      public PreparedStatement prepareStatement​(String sql, int flag) throws SQLServerException
      Specified by:
      prepareStatement in interface Connection
      Throws:
      SQLServerException

    • prepareStatement

      public PreparedStatement prepareStatement​(String sql, int flag, SQLServerStatementColumnEncryptionSetting stmtColEncSetting) throws SQLServerException
      Description copied from interface: ISQLServerConnection
      Creates a default PreparedStatement object that has the capability to retrieve auto-generated keys. The given constant tells the driver whether it should make auto-generated keys available for retrieval. This parameter is ignored if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific).

      Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation. In this case, the statement may not be sent to the database until the PreparedStatement object is executed. This has no direct effect on users; however, it does affect which methods throw certain SQLExceptions.

      Result sets created using the returned PreparedStatement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY. The holdability of the created result sets can be determined by calling Connection.getHoldability().

      Specified by:
      prepareStatement in interface ISQLServerConnection
      Parameters:
      sql - an SQL statement that may contain one or more '?' IN parameter placeholders
      flag - a flag indicating whether auto-generated keys should be returned; one of Statement.RETURN_GENERATED_KEYS or Statement.NO_GENERATED_KEYS
      stmtColEncSetting - Specifies how data will be sent and received when reading and writing encrypted columns.
      Returns:
      a new PreparedStatement object, containing the pre-compiled SQL statement, that will have the capability of returning auto-generated keys
      Throws:
      SQLServerException - if a database access error occurs, this method is called on a closed connection or the given parameter is not a Statement constant indicating whether auto-generated keys should be returned

    • prepareStatement

      public PreparedStatement prepareStatement​(String sql, int[] columnIndexes) throws SQLServerException
      Specified by:
      prepareStatement in interface Connection
      Throws:
      SQLServerException

    • prepareStatement

      public PreparedStatement prepareStatement​(String sql, int[] columnIndexes, SQLServerStatementColumnEncryptionSetting stmtColEncSetting) throws SQLServerException
      Description copied from interface: ISQLServerConnection
      Creates a default PreparedStatement object capable of returning the auto-generated keys designated by the given array. This array contains the indexes of the columns in the target table that contain the auto-generated keys that should be made available. The driver will ignore the array if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific).

      An SQL statement with or without IN parameters can be pre-compiled and stored in a PreparedStatement object. This object can then be used to efficiently execute this statement multiple times.

      Note: This method is optimized for handling parametric SQL statements that benefit from precompilation. If the driver supports precompilation, the method prepareStatement will send the statement to the database for precompilation. Some drivers may not support precompilation. In this case, the statement may not be sent to the database until the PreparedStatement object is executed. This has no direct effect on users; however, it does affect which methods throw certain SQLExceptions.

      Result sets created using the returned PreparedStatement object will by default be type TYPE_FORWARD_ONLY and have a concurrency level of CONCUR_READ_ONLY. The holdability of the created result sets can be determined by calling Connection.getHoldability().

      Specified by:
      prepareStatement in interface ISQLServerConnection
      Parameters:
      sql - an SQL statement that may contain one or more '?' IN parameter placeholders
      columnIndexes - an array of column indexes indicating the columns that should be returned from the inserted row or rows
      stmtColEncSetting - Specifies how data will be sent and received when reading and writing encrypted columns.
      Returns:
      a new PreparedStatement object, containing the pre-compiled statement, that is capable of returning the auto-generated keys designated by the given array of column indexes
      Throws:
      SQLServerException - if a database access error occurs or this method is called on a closed connection

      public boolean isValid​(int timeout) throws SQLException
      Determine whether the connection is still valid.

      Returns:
      true if the connection has not been closed and is still valid.
      Throws:
      SQLException - if the value supplied for the timeout is less than 0.

    • getEnablePrepareOnFirstPreparedStatementCall

      public boolean getEnablePrepareOnFirstPreparedStatementCall()
      Description copied from interface: ISQLServerConnection
      Returns the behavior for a specific connection instance. If false the first execution will call sp_executesql and not prepare a statement, once the second execution happens it will call sp_prepexec and actually setup a prepared statement handle. Following executions will call sp_execute. This relieves the need for sp_unprepare on prepared statement close if the statement is only executed once. The default for this option can be changed by calling setDefaultEnablePrepareOnFirstPreparedStatementCall().
      Specified by:
      getEnablePrepareOnFirstPreparedStatementCall in interface ISQLServerConnection
      Returns:
      Returns the current setting per the description.

    • getServerPreparedStatementDiscardThreshold

      public int getServerPreparedStatementDiscardThreshold()
      Description copied from interface: ISQLServerConnection
      Returns the behavior for a specific connection instance. This setting controls how many outstanding prepared statement discard actions (sp_unprepare) can be outstanding per connection before a call to clean-up the outstanding handles on the server is executed. If the setting is <= 1, unprepare actions will be executed immedietely on prepared statement close. If it is set to > 1, these calls will be batched together to avoid overhead of calling sp_unprepare too often. The default for this option can be changed by calling getDefaultServerPreparedStatementDiscardThreshold().
      Specified by:
      getServerPreparedStatementDiscardThreshold in interface ISQLServerConnection
