Constructor Details

JenaStatement

public JenaStatement(JenaConnection connection)
              throws SQLException

Creates a new statement

Parameters:

connection - Connection

Throws:

SQLException - Thrown if the arguments are invalid

JenaStatement

public JenaStatement(JenaConnection connection,
 int type,
 int fetchDir,
 int fetchSize,
 int holdability,
 boolean autoCommit,
 int transactionLevel)
              throws SQLException

Creates a new statement

Parameters:

connection - Connection

type - Result Set type for result sets produced by this statement

fetchDir - Fetch Direction

fetchSize - Fetch Size

holdability - Result Set holdability

autoCommit - Auto-commit behaviour

transactionLevel - Transaction level

Throws:

SQLException - Thrown if there is an error with the statement parameters

Method Details

getJenaConnection

public JenaConnection getJenaConnection()

Gets the underlying JenaConnection implementation, useful for accessing Jena JDBC specific information such as desired JDBC compatibility level

Returns:

Underlying Jena Connection

getJdbcCompatibilityLevel

public int getJdbcCompatibilityLevel()

Gets the JDBC compatibility level that is in use, see JdbcCompatibility for explanations

By default this is set at the connection level and inherited, however you may call setJdbcCompatibilityLevel(int) to set the compatibility level for this statement. This allows you to change the compatibility level on a per-query basis if so desired.

Returns:

Compatibility level

setJdbcCompatibilityLevel

public void setJdbcCompatibilityLevel(int level)

Sets the JDBC compatibility level that is in use, see JdbcCompatibility for explanations.

By default this is set at the connection level and inherited, however you may call setJdbcCompatibilityLevel(int) to set the compatibility level for this statement. This allows you to change the compatibility level on a per-query basis if so desired.

Changing the level may not effect existing open objects, behaviour in this case will be implementation specific.

Parameters:

level - Compatibility level
