Constructor Detail

Neo4jStatement

protected Neo4jStatement(Neo4jConnection connection)

Default constructor with JDBC connection.

Parameters:

connection - The JDBC connection

Method Detail

checkClosed

protected void checkClosed()
                    throws SQLException

Check if this statement is closed or not. If it is, we throw an exception.

Throws:

SQLException - sqlexception

getConnection

public Neo4jConnection getConnection()
                              throws SQLException

Specified by:

getConnection in interface Statement

Throws:

SQLException

getUpdateCount

public int getUpdateCount()
                   throws SQLException

/!\ Like javadoc said, this method should be called one times. Bolt statement always return two results : ResulSet and updatecount. Because each time we retrieve a data we set it to the default value here we have two cases : - if there a resultset : we tell it by responding -1 - otherwise we give the updatecount and reset its value to default

Specified by:

getUpdateCount in interface Statement

Throws:

SQLException

getResultSet

public ResultSet getResultSet()
                       throws SQLException

Like javadoc said, this method should be called one time.

Specified by:

getResultSet in interface Statement

Throws:

SQLException

getMaxRows

public int getMaxRows()
               throws SQLException

Specified by:

getMaxRows in interface Statement

Throws:

SQLException

setMaxRows

public void setMaxRows(int max)
                throws SQLException

Specified by:

setMaxRows in interface Statement

Throws:

SQLException

isClosed

public boolean isClosed()
                 throws SQLException

Specified by:

isClosed in interface Statement

Throws:

SQLException

close

public void close()
           throws SQLException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Statement

Throws:

SQLException

unwrap

public <T> T unwrap(Class<T> iface)
             throws SQLException

Specified by:

unwrap in interface Wrapper

Throws:

SQLException

isWrapperFor

public boolean isWrapperFor(Class<?> iface)
                     throws SQLException

Specified by:

Throws:

SQLException

setFetchSize

public void setFetchSize(int rows)
                  throws SQLException

Some tools call this method, so this just a workaround to make it work. If you set the fetch at Integer.MIN_VALUE, or if you put maxRows to -1, there is no exception. It's pretty much the same hack as the mysql connector.

Specified by:

setFetchSize in interface Statement

Throws:

SQLException

getMoreResults

public boolean getMoreResults()
                       throws SQLException

If there's a result set to consume, it's true

Specified by:

getMoreResults in interface Statement

Throws:

SQLException

getWarnings

public SQLWarning getWarnings()
                       throws SQLException

Some tool call this method, so for now just respond null. It will be possible to implement this an explain.

Specified by:

getWarnings in interface Statement

Throws:

SQLException

clearWarnings

public void clearWarnings()
                   throws SQLException

Some tool call this method.

Specified by:

clearWarnings in interface Statement

Throws:

SQLException

getQueryTimeout

public int getQueryTimeout()
                    throws SQLException

Added just for value memorization

Specified by:

getQueryTimeout in interface Statement

Returns:

the current query timeout limit in seconds; zero means there is no limit

Throws:

SQLException - if a database error occurs

setQueryTimeout

public void setQueryTimeout(int seconds)
                     throws SQLException

Added just for value memorization

Specified by:

setQueryTimeout in interface Statement

Parameters:

seconds - the new query timeout limit in seconds; zero means there is no limit

Throws:

SQLException - if a database error occurs
