Modifier and Type	Method and Description
java.sql.ResultSet	executeQuery(java.lang.String sql, boolean withHold) An Informix extension to execute an SQL statement that returns a single ResultSet.
boolean	getAutoFree() An Informix extension that returns the current autofree mode of this statement.
long	getBigSerial() An Informix extension that returns the bigserial value of the last row inserted.
int	getFetchBufferSize() returns the fetch buffer size if set for this statement object
int	getSerial() An Informix extension that returns the serial value of the last row inserted.
long	getSerial8() An Informix extension that returns the serial8 value of the last row inserted.
int	getStatementType() An Informix extention to return the statement type returned by preparing the SQL statement.
void	setAutoFree(boolean flag) An Informix extension that allows the user to set the autofree property for this statement.
void	setFetchBufferSize(int bufferSize) An Informix extension that sets the buffer size for this Statement object for fetch operation This value will override any FET_BUF_SIZE connection level property and is useful when OPTOFC property is set Server will use this value as hint to determin the maximum buffer size to send the data to the clients.

Method Detail

getSerial

int getSerial()
       throws java.sql.SQLException

An Informix extension that returns the serial value of the last row inserted.

Returns:

The serial value of the last row inserted. If no rows were inserted, returns 0.

Throws:

java.sql.SQLException

getSerial8

long getSerial8()
         throws java.sql.SQLException

An Informix extension that returns the serial8 value of the last row inserted.

Returns:

The serial8 value of the last row inserted. If no rows were inserted, returns 0.

Throws:

java.sql.SQLException

setAutoFree

void setAutoFree(boolean flag)

An Informix extension that allows the user to set the autofree property for this statement. The resource for this statement is immediately released after the statement is executed. If the statement is a query, the resource is released after the last row is fetched.

Parameters:

flag - Indicates whether the autofree property is true (set) or false.

getAutoFree

boolean getAutoFree()

An Informix extension that returns the current autofree mode of this statement.

Returns:

the autofree value of this statement: true (set) or false.

executeQuery

java.sql.ResultSet executeQuery(java.lang.String sql,
                                boolean withHold)
                         throws java.sql.SQLException

An Informix extension to execute an SQL statement that returns a single ResultSet. The statement is executed with a hold cursor that spans across the transaction boundary.

Parameters:

sql - The SQL statement.

withHold - Specifies whether the cursor has a hold or not.

Returns:

the table of data produced by the SQL statement.

Throws:

java.sql.SQLException

getStatementType

int getStatementType()

An Informix extention to return the statement type returned by preparing the SQL statement. The number returned by this method can be deciphered by looking into the IfxStatementTypes.java file that is now exported to the user.

Returns:

the statement type id

getBigSerial

long getBigSerial()
           throws java.sql.SQLException

An Informix extension that returns the bigserial value of the last row inserted.

Returns:

The bigserial value of the last row inserted. If no rows were inserted, returns 0.

Throws:

java.sql.SQLException

setFetchBufferSize

void setFetchBufferSize(int bufferSize)

An Informix extension that sets the buffer size for this Statement object for fetch operation This value will override any FET_BUF_SIZE connection level property and is useful when OPTOFC property is set Server will use this value as hint to determin the maximum buffer size to send the data to the clients.

Parameters:

bufferSize - : number of bytes not exceeding 2GB

Throws:

java.sql.SQLException

Since:

4.10.JC3

getFetchBufferSize

int getFetchBufferSize()

returns the fetch buffer size if set for this statement object

Returns:

Since:
