execute

public final boolean execute(java.lang.String sql)
                      throws java.sql.SQLException
Description copied from class: EmbedStatement
Execute a SQL statement that may return multiple results. Under some (uncommon) situations a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this, unless you're executing a stored procedure that you know may return multiple results, or unless you're dynamically executing an unknown SQL string. The "execute", "getMoreResults", "getResultSet" and "getUpdateCount" methods let you navigate through multiple results. The "execute" method executes a SQL statement and indicates the form of the first result. You can then use getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s).

Specified by:
execute in interface java.sql.Statement
Overrides:
execute in class EmbedStatement
Parameters:
sql - any SQL statement
Returns:
true if the first result is a ResultSet; false if it is an integer
Throws:
java.sql.SQLException - thrown on failure
See Also:
EmbedStatement.getResultSet(), EmbedStatement.getUpdateCount(), EmbedStatement.getMoreResults()

clearParameters

public void clearParameters()
                     throws java.sql.SQLException

In general, parameter values remain in force for repeated use of a Statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling clearParameters.

Specified by:
clearParameters in interface java.sql.PreparedStatement
Throws:
java.sql.SQLException - thrown on failure.

getMetaData

                            int scale)
                     throws java.sql.SQLException
The interface says that the type of the Object parameter must be compatible with the type of the targetSqlType. We check that, and if it flies, we expect the underlying engine to do the required conversion once we pass in the value using its type. So, an Integer converting to a CHAR is done via setInteger() support on the underlying CHAR type.

If x is null, it won't tell us its type, so we pass it on to setNull

Specified by:
setObject in interface java.sql.PreparedStatement
Parameters:
parameterIndex - The first parameter is 1, the second is 2, ...
x - The object containing the input parameter value
targetSqlType - The SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.
scale - For java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types this is the number of digits after the decimal. For all other types this value will be ignored,
Throws:
java.sql.SQLException - thrown on failure.

Set the value of a parameter using an object; use the java.lang equivalent objects for integral values.

The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument java object will be converted to the corresponding SQL type before being sent to the database.

Note that this method may be used to pass datatabase specific abstract data types, by using a Driver specific Java type.

Specified by:
setObject in interface java.sql.PreparedStatement
Parameters:
parameterIndex - The first parameter is 1, the second is 2, ...
x - The object containing the input parameter value

getParms

public final ParameterValueSet getParms()
Get the ParameterValueSet from the activation. The caller of this method should be aware that the activation associated with a Statement can change and hence the ParameterValueSet returned by this call should not be hold onto. An example of this can be seen in EmbedCallableStatement.executeStatement where at the beginning of the method, we check the validity of the parameters. But we donot keep the parameters in a local variable to use later. The reason for this is that the next call in the method, super.executeStatement can recompile the statement and create a new activation if the statement plan has been invalidated. To account for this possibility, EmbedCallableStatement.executeStatement makes another call to get the ParameterValueSet before stuffing the output parameter value into the ParameterValueSet object.

Returns:
The ParameterValueSet for the activation

public void transferParameters(EmbedPreparedStatement newStatement)
                        throws java.sql.SQLException
Throws:
java.sql.SQLException

executeStatement

boolean executeStatement(Activation a,
                         boolean executeQuery,
                         boolean executeUpdate)

dataTypeConversion

final java.sql.SQLException dataTypeConversion(int column,
                                               java.lang.String sourceType)
                                        throws java.sql.SQLException
Throws:
java.sql.SQLException

setBrokeredConnectionControl

public void setBrokeredConnectionControl(BrokeredConnectionControl control)
This method is used to initialize the BrokeredConnectionControl variable with its implementation. This method will be called in the BrokeredConnectionControl class

Parameters:
control - used to call the onStatementClose and onStatementErrorOccurred methods that have logic to raise StatementEvents for the close and error events on the PreparedStatement

checkStatementValidity

private void checkStatementValidity(java.sql.SQLException sqle)
                             throws java.sql.SQLException
Method calls onStatementError occurred on the BrokeredConnectionControl class after checking the SQLState of the SQLException thrown. In the case that a XAConnection is involved in the creation of this PreparedStatement for e.g in the following case XAConnection xaconn = xadatasource.getXAConnection();//where xadatasource is an object of XADataSource Connection conn = xaconnection.getConnection(); PreparedStatement ps = conn.preparedStatement("values 1"); In the above case the PreparedStatement will actually be a BrokeredPreparedStatement40 object. Hence when we call bcc.onStatementClose and pass the PreparedStatement that caused it applicationStatement will be the appropriate choice since it will contain the appropriate instance of PreparedStatement in each case

Throws:
java.sql.SQLException

checkForSupportedDataType

private void checkForSupportedDataType(int dataType)
                                throws java.sql.SQLException
Checks whether a data type is supported for setObject(int, Object, int) and setObject(int, Object, int, int).

Parameters:
dataType - the data type to check
Throws:
java.sql.SQLException - if the type is not supported

setAsciiStream

public void setAsciiStream(int parameterIndex,
                           java.io.InputStream x)
                    throws java.sql.SQLException
Sets the designated parameter to the given input stream. When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format. Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Specified by:
setAsciiStream in interface java.sql.PreparedStatement
Parameters:
parameterIndex - the first parameter is 1, the second is 2, ...
x - the Java input stream that contains the ASCII parameter value
Throws:
java.sql.SQLException - if a database access error occurs or this method is called on a closed PreparedStatement

setCharacterStream

public void setCharacterStream(int parameterIndex,
                               java.io.Reader reader)
                        throws java.sql.SQLException
Sets the designated parameter to the given Reader object. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.Reader object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format. Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface. Using this lengthless overload is not less effective than using one where the stream length is specified, but since there is no length specified, the exact length check will not be performed.

Specified by:
setCharacterStream in interface java.sql.PreparedStatement
Specified by:
setCharacterStream in interface EnginePreparedStatement
Parameters:
parameterIndex - the first parameter is 1, the second is 2, ...
reader - the java.io.Reader object that contains the Unicode data
Throws:
java.sql.SQLException - if a database access error occurs or this method is called on a closed PreparedStatement

setClob

public void setClob(int parameterIndex,
                    java.io.Reader reader)
             throws java.sql.SQLException
Sets the designated parameter to a Reader object. This method differs from the setCharacterStream(int,Reader) method because it informs the driver that the parameter value should be sent to the server as a CLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARCHAR or a CLOB.

Specified by:
setClob in interface java.sql.PreparedStatement
Parameters:
parameterIndex - index of the first parameter is 1, the second is 2, ...
reader - an object that contains the data to set the parameter value to.
Throws:
java.sql.SQLException - if a database access error occurs, this method is called on a closed PreparedStatementor if parameterIndex does not correspond to a parameter marker in the SQL statement

setClob

public void setClob(int parameterIndex,
                    java.io.Reader reader,
                    long length)
             throws java.sql.SQLException
Sets the designated parameter to a Reader object.

Specified by:
setClob in interface java.sql.PreparedStatement
Parameters:
parameterIndex - index of the first parameter is 1, the second is 2, ...
reader - An object that contains the data to set the parameter value to.
length - the number of characters in the parameter data.
Throws:
java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement, or if the length specified is less than zero.

setBlob

public void setBlob(int parameterIndex,
                    java.io.InputStream inputStream)
             throws java.sql.SQLException
Sets the designated parameter to a InputStream object. This method differs from the setBinaryStream(int, InputStream) method because it informs the driver that the parameter value should be sent to the server as a BLOB. When the setBinaryStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGVARBINARY or a BLOB

Specified by:
setBlob in interface java.sql.PreparedStatement
Parameters:
parameterIndex - index of the first parameter is 1, the second is 2, ...
inputStream - an object that contains the data to set the parameter value to.
Throws:
java.sql.SQLException - if a database access error occurs, this method is called on a closed PreparedStatement or if parameterIndex does not correspond to a parameter marker in the SQL statement

setBlob

public void setBlob(int parameterIndex,
                    java.io.InputStream inputStream,
                    long length)
             throws java.sql.SQLException
Sets the designated parameter to a InputStream object.

Specified by:
setBlob in interface java.sql.PreparedStatement
Parameters:
parameterIndex - index of the first parameter is 1, the second is 2, ...
inputStream - An object that contains the data to set the parameter value to.
length - the number of bytes in the parameter data.
Throws:
java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement, if the length specified is less than zero or if the number of bytes in the inputstream does not match the specfied length.

checkBlobConditions

private final void checkBlobConditions(int parameterIndex)
                                throws java.sql.SQLException
Check general (pre)conditions for setBlob methods.

Parameters:
parameterIndex - 1-based index of the parameter.
Throws:
java.sql.SQLException
