public static enum
Resultset.Type

Method Summary

Modifier and TypeMethod and Description
public void
clearNextResultset()

Clears the reference to the next result set in a multi-result set "chain".

public ColumnDefinition
getColumnDefinition()

public Resultset

Returns:

the next Resultset
getNextResultset()

Returns the next ResultSet in a multi-resultset "chain", if any, null if none exists.

public int

Returns:

result id
getResultId()

The id (used when profiling) to identify us

public ResultsetRows
getRows()

public String

Returns:

the server informational message
getServerInfo()

Returns the server informational message returned from a DDL or DML statement (if any), or null if none.

public long

Returns:

return the update count for this result set (if one exists), otherwise -1.
getUpdateCount()

Returns the update count for this result set (if one exists), otherwise -1.

public long

Returns:

the AUTO_INCREMENT value for the DDL/DML statement which created this result set.
getUpdateID()

Returns the AUTO_INCREMENT value for the DDL/DML statement which created this result set.

public boolean

Returns:

true if result set contains rows
hasRows()

Does the result set contain rows, or is it the result of a DDL or DML statement?

public void
initRowsWithMetadata()

Set metadata of this Resultset to ResultsetRows it contains.

public void
setColumnDefinition(ColumnDefinition
field-level metadata for the result set
metadata)

Sometimes the driver doesn't have metadata before consuming the result set rows (because it's cached), or need to coerce the metadata returned by queries into that required by the particular specification (eg metadata returned by metadata queries into that required by the JDBC specification).

public void
setNextResultset(Resultset
Sets the next result set in the result set chain for multiple result sets.

public Resultset getNextResultset()

Returns the next ResultSet in a multi-resultset "chain", if any, null if none exists.

Returns:Resultset

the next Resultset

getServerInfoback to summary
public String getServerInfo()

Returns the server informational message returned from a DDL or DML statement (if any), or null if none.

Returns:String

the server informational message

getUpdateCountback to summary
public long getUpdateCount()

Returns the update count for this result set (if one exists), otherwise -1.

Returns:long

return the update count for this result set (if one exists), otherwise -1.

getUpdateIDback to summary
public long getUpdateID()

Returns the AUTO_INCREMENT value for the DDL/DML statement which created this result set.

Returns:long

the AUTO_INCREMENT value for the DDL/DML statement which created this result set.

hasRowsback to summary
public boolean hasRows()

Does the result set contain rows, or is it the result of a DDL or DML statement?

Returns:boolean

true if result set contains rows

initRowsWithMetadataback to summary
public void initRowsWithMetadata()

Set metadata of this Resultset to ResultsetRows it contains.

setColumnDefinitionback to summary
public void setColumnDefinition(ColumnDefinition metadata)

Sometimes the driver doesn't have metadata before consuming the result set rows (because it's cached), or need to coerce the metadata returned by queries into that required by the particular specification (eg metadata returned by metadata queries into that required by the JDBC specification). So it can call this to set it after the fact.

Parameters
metadata:ColumnDefinition

field-level metadata for the result set

setNextResultsetback to summary
public void setNextResultset(Resultset nextResultset)
Parameters
nextResultset:Resultset

Sets the next result set in the result set chain for multiple result sets.
