Constructor Summary

UnknownRequest(CJDBCInputStream in)

UnknownRequest(java.lang.String sqlQuery, boolean escapeProcessing, int timeout, java.lang.String lineSeparator)
Creates a new UnknownRequest instance.

Method Summary

void	cloneParsing(AbstractRequest request) Throws always an SQLException: it is not possible to parse an unknown request because we don't know its syntax or semantic.
boolean	needsMacroProcessing() Returns true if this request requires macro (RAND(), NOW(), ...) processing.
void	parse(DatabaseSchema schema, int granularity, boolean isCaseSensitive) Throws always an SQLException: it is not possible to parse an unknown request because we don't know its syntax or semantic.
boolean	returnsResultSet() Does this request returns a ResultSet?
void	sendToStream(CJDBCOutputStream out, boolean needSqlSkeleton) Serialize the request on the output stream by sending only the needed parameters to reconstruct it on the controller.

Constructor Detail

UnknownRequest

public UnknownRequest(java.lang.String sqlQuery,
                      boolean escapeProcessing,
                      int timeout,
                      java.lang.String lineSeparator)

Creates a new UnknownRequest instance.

Parameters:

sqlQuery - the SQL query

escapeProcessing - should the driver to escape processing before sending to the database?

timeout - an int value

lineSeparator - the line separator used in the query

UnknownRequest

public UnknownRequest(CJDBCInputStream in)
               throws java.io.IOException

Method Detail

sendToStream

public void sendToStream(CJDBCOutputStream out,
                         boolean needSqlSkeleton)
                  throws java.io.IOException

Description copied from class: AbstractRequest

Serialize the request on the output stream by sending only the needed parameters to reconstruct it on the controller. Has to mirror the deserialization method above.

Overrides:

sendToStream in class AbstractRequest

Parameters:

out - destination CJDBCOutputStream

needSqlSkeleton - true if controller wants SQL templates

Throws:

java.io.IOException - if fails

AbstractRequest

needsMacroProcessing

public boolean needsMacroProcessing()

Description copied from class: AbstractRequest

Returns true if this request requires macro (RAND(), NOW(), ...) processing.

Specified by:

needsMacroProcessing in class AbstractRequest

Returns:

false

See Also:

AbstractRequest.needsMacroProcessing()

returnsResultSet

public boolean returnsResultSet()

Description copied from class: AbstractRequest

Does this request returns a ResultSet?

Specified by:

returnsResultSet in class AbstractRequest

Returns:

true is this request will return a ResultSet

See Also:

AbstractRequest.returnsResultSet()

parse

public void parse(DatabaseSchema schema,
                  int granularity,
                  boolean isCaseSensitive)
           throws java.sql.SQLException

Throws always an SQLException: it is not possible to parse an unknown request because we don't know its syntax or semantic.

Specified by:

parse in class AbstractRequest

Parameters:

schema - a DatabaseSchema value

granularity - parsing granularity as defined in ParsingGranularities

isCaseSensitive - true if parsing must be case sensitive

Throws:

java.sql.SQLException - if the parsing fails

See Also:

AbstractRequest.parse(org.objectweb.cjdbc.common.sql.schema.DatabaseSchema, int, boolean)

cloneParsing

public void cloneParsing(AbstractRequest request)

Throws always an SQLException: it is not possible to parse an unknown request because we don't know its syntax or semantic.

Specified by:

cloneParsing in class AbstractRequest

Parameters:

request - the parsed request to clone
