getClientConnectionId
java.util.UUID getClientConnectionId() throws SQLServerException
Returns the connection ID of the most recent connection attempt, regardless of whether the attempt succeeded or failed.- Returns:
- 16-byte GUID representing the connection ID of the most recent connection attempt. Or, NULL if there is a failure after the connection request is initiated and the pre-login handshake.
- Throws:
SQLServerException
- If any errors occur.
-
createStatement
java.sql.Statement createStatement(int nType, int nConcur, int nHold, SQLServerStatementColumnEncryptionSetting stmtColEncSetting) throws SQLServerException
Creates aStatement
object that will generateResultSet
objects with the given type, concurrency, and holdability. This method is the same as thecreateStatement
method above, but it allows the default result set type, concurrency, and holdability to be overridden.- Parameters:
nType
- one of the followingResultSet
constants:ResultSet.TYPE_FORWARD_ONLY
,ResultSet.TYPE_SCROLL_INSENSITIVE
, orResultSet.TYPE_SCROLL_SENSITIVE
nConcur
- one of the followingResultSet
constants:ResultSet.CONCUR_READ_ONLY
orResultSet.CONCUR_UPDATABLE
nHold
- one of the followingResultSet
constants:ResultSet.HOLD_CURSORS_OVER_COMMIT
orResultSet.CLOSE_CURSORS_AT_COMMIT
stmtColEncSetting
- Specifies how data will be sent and received when reading and writing encrypted columns.- Returns:
- a new
Statement
object that will generateResultSet
objects with the given type, concurrency, and holdability - Throws:
SQLServerException
- if a database access error occurs, this method is called on a closed connection or the given parameters are notResultSet
constants indicating type, concurrency, and holdability
-
prepareStatement
java.sql.PreparedStatement prepareStatement(java.lang.String sql, int flag, SQLServerStatementColumnEncryptionSetting stmtColEncSetting) throws SQLServerException
Creates a defaultPreparedStatement
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 anINSERT
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 thePreparedStatement
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 typeTYPE_FORWARD_ONLY
and have a concurrency level ofCONCUR_READ_ONLY
. The holdability of the created result sets can be determined by callingConnection.getHoldability()
.- Parameters:
sql
- an SQL statement that may contain one or more '?' IN parameter placeholdersflag
- a flag indicating whether auto-generated keys should be returned; one ofStatement.RETURN_GENERATED_KEYS
orStatement.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 aStatement
constant indicating whether auto-generated keys should be returned
-
prepareStatement
java.sql.PreparedStatement prepareStatement(java.lang.String sql, int[] columnIndexes, SQLServerStatementColumnEncryptionSetting stmtColEncSetting) throws SQLServerException
Creates a defaultPreparedStatement
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 anINSERT
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 thePreparedStatement
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 typeTYPE_FORWARD_ONLY
and have a concurrency level ofCONCUR_READ_ONLY
. The holdability of the created result sets can be determined by callingConnection.getHoldability()
.- Parameters:
sql
- an SQL statement that may contain one or more '?' IN parameter placeholderscolumnIndexes
- an array of column indexes indicating the columns that should be returned from the inserted row or rowsstmtColEncSetting

Returns the number of currently outstanding prepared statement un-prepare actions.- Returns:
- Returns the current value per the description.
-
closeUnreferencedPreparedStatementHandles
void closeUnreferencedPreparedStatementHandles()
Forces the un-prepare requests for any outstanding discarded prepared statements to be executed.
-
getEnablePrepareOnFirstPreparedStatementCall
boolean getEnablePrepareOnFirstPreparedStatementCall()
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().- Returns:
- Returns the current setting per the description.
-
setEnablePrepareOnFirstPreparedStatementCall
void setEnablePrepareOnFirstPreparedStatementCall(boolean value)
Sets the behavior for a specific connection instance. If value is 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.- Parameters:
value
- Changes the setting per the description.
-
getServerPreparedStatementDiscardThreshold
int getServerPreparedStatementDiscardThreshold()
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().- Returns:
- Returns the current setting per the description.
-
setServerPreparedStatementDiscardThreshold
void setServerPreparedStatementDiscardThreshold(int value)
Sets the behavior for a specific connection instance.
