接口 JdbcStatement

所有超级接口:

AutoCloseable, Query, Statement, Wrapper

所有已知子接口:

JdbcPreparedStatement

所有已知实现类:

CallableStatement, ClientPreparedStatement, ServerPreparedStatement, StatementImpl

public interface JdbcStatement
extends Statement, Query

This interface contains methods that are considered the "vendor extension" to the JDBC API for MySQL's implementation of java.sql.Statement. For those looking further into the driver implementation, it is not an API that is used for plugability of implementations inside our driver (which is why there are still references to StatementImpl throughout the code).

方法详细资料

enableStreamingResults

void enableStreamingResults()
                     throws SQLException

Workaround for containers that 'check' for sane values of Statement.setFetchSize() so that applications can use the Java variant of libmysql's mysql_use_result() behavior.

抛出:

SQLException - if an error occurs

disableStreamingResults

void disableStreamingResults()
                      throws SQLException

Resets this statements fetch size and result set type to the values they had before enableStreamingResults() was called.

抛出:

SQLException - if an error occurs

setLocalInfileInputStream

void setLocalInfileInputStream(InputStream stream)

Sets an InputStream instance that will be used to send data to the MySQL server for a "LOAD DATA LOCAL INFILE" statement rather than a FileInputStream or URLInputStream that represents the path given as an argument to the statement. This stream will be read to completion upon execution of a "LOAD DATA LOCAL INFILE" statement, and will automatically be closed by the driver, so it needs to be reset before each call to execute*() that would cause the MySQL server to request data to fulfill the request for "LOAD DATA LOCAL INFILE". If this value is set to NULL, the driver will revert to using a FileInputStream or URLInputStream as required.

参数:

stream - input stream

getLocalInfileInputStream

InputStream getLocalInfileInputStream()

Returns the InputStream instance that will be used to send data in response to a "LOAD DATA LOCAL INFILE" statement. This method returns NULL if no such stream has been set via setLocalInfileInputStream().

返回:

input stream

setPingTarget

void setPingTarget(PingTarget pingTarget)

getExceptionInterceptor

ExceptionInterceptor getExceptionInterceptor()

removeOpenResultSet

void removeOpenResultSet(ResultSetInternalMethods rs)

Callback for result set instances to remove them from the Set that tracks them per-statement

参数:

rs - result set

getOpenResultSetCount

int getOpenResultSetCount()

Returns the number of open result sets for this statement.

返回:

the number of open result sets for this statement

setHoldResultsOpenOverClose

void setHoldResultsOpenOverClose(boolean holdResultsOpenOverClose)

getQuery

Query getQuery()

setAttribute

void setAttribute(String name,
                  Object value)

clearAttributes

void clearAttributes()

getResultSetInternal

ResultSetInternalMethods getResultSetInternal()
