execute
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

- Overrides:
execute
in classEmbedStatement
- Parameters:
sql
- any SQL statement- Returns:
- true if the first result is a ResultSet; false if it is an integer

i
- the first parameter is 1, the second is 2, ...x
- an object representing an SQL array- Throws:
SQLException
- Feature not implemented for now.
-
setObject
public final void setObject(int parameterIndex, Object x, int targetSqlType, int scale) throws 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 interfacePreparedStatement
- Parameters:
parameterIndex
- The first parameter is 1, the second is 2, ...x
- The object containing the input parameter valuetargetSqlType
- 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:
SQLException
- thrown on failure.
-
setObject
This method is like setObject above, but assumes a scale of zero.- Specified by:
setObject
in interfacePreparedStatement
- Throws:
SQLException
- thrown on failure.
-
setObject
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 interfacePreparedStatement
- Parameters:
parameterIndex
- The first parameter is 1, the second is 2, ...x
- The object containing the input parameter value- Throws:
SQLException

-
execute
- Specified by:
execute
in interfacePreparedStatement
- Throws:
SQLException

-
setDate
Set a parameter to a java.sql.Date value. The driver converts this to a SQL DATE value when it sends it to the database.- Specified by:
setDate
in interfacePreparedStatement

parameterIndex
- the first parameter is 1, the second is 2, ...x
- the parameter value- Throws:
SQLException
- Feature not implemented for now.
-

Set a parameter to a java.sql.Time value. The driver converts this to a SQL TIME value when it sends it to the database.- Specified by:
setTime
in interfacePreparedStatement
- Parameters:
parameterIndex
- the first parameter is 1, the second is 2, ...x
- the parameter value- Throws:
SQLException

i
- the first parameter is 1, the second is 2, ...x
- an object representing a CLOB- Throws:
SQLException
-
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
-
getParameterJDBCType
Get the target JDBC type for a parameter. Will throw exceptions if the parameter index is out of range. The parameterIndex is 1-based.- Throws:
SQLException
- parameter is out of range
-
getParameterSQLType
Return the SQL type name for the parameter.- Parameters:
parameterIndex
- the 1-based index of the parameter- Returns:
- SQL name of the parameter

parameterIndex
- The first parameter is 1, the second is 2, ...scale
- The scale- Throws:
SQLException
- thrown on failure.
-
setURL
JDBC 3.0 Sets the designated parameter to the given java.net.URL value. The driver converts this to an SQL DATALINK value when it sends it to the database.- Specified by:
setURL
in interfacePreparedStatement
- Parameters:
parameterIndex
- - the first parameter is 1, the second is 2, ...x
- - the java.net.URL object to be set- Throws:
SQLException
- Feature not implemented for now.
-
getParameterMetaData

getParameterMetaData
in interfacePreparedStatement
- Returns:
- a ParameterMetaData object that contains information about the number, types and properties of this PreparedStatement object's parameters.

SQLException
- if a database access error occurs
-
newEmbedResultSetMetaData
-
toString
-
transferParameters
- Throws:
SQLException
-
executeStatement
boolean executeStatement(Activation a, boolean executeQuery, boolean executeUpdate) throws SQLException Description copied from class:EmbedStatement
Execute the current statement.- Overrides:
executeStatement
in classEmbedStatement
- Throws:
SQLException
- thrown on failure.
-
dataTypeConversion
- Throws:
SQLException
-
setBrokeredConnectionControl
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
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 caseXAConnection 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 BrokeredPreparedStatement 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:
SQLException
-
setAsciiStream
Sets the designated parameter to the given input stream. When a very large ASCII value is input to aLONGVARCHAR
parameter, it may be more practical to send it via ajava.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 interfacePreparedStatement
- Parameters:
parameterIndex
- the first parameter is 1, the second is 2, ...x
- the Java input stream that contains the ASCII parameter value- Throws:
SQLException
- if a database access error occurs or this method is called on a closedPreparedStatement
-
setCharacterStream
Sets the designated parameter to the givenReader
object. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via ajava.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 interfacePreparedStatement
- Parameters:
parameterIndex
- the first parameter is 1, the second is 2, ...reader
- thejava.io.Reader
object that contains the Unicode data- Throws:
SQLException
- if a database access error occurs or this method is called on a closedPreparedStatement
-
setClob
Sets the designated parameter to aReader
object. This method differs from thesetCharacterStream(int,Reader)
method because it informs the driver that the parameter value should be sent to the server as aCLOB
. When thesetCharacterStream
method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as aLONGVARCHAR
or aCLOB
.- Specified by:
setClob
in interfacePreparedStatement
- 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:
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
Sets the designated parameter to a Reader object.- Specified by:
setClob
in interfacePreparedStatement
- 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:
SQLException
- if parameterIndex does not correspond to a parameter marker in the SQL statement, or if the length specified is less than zero.
-
setBlob
Sets the designated parameter to aInputStream
object. This method differs from thesetBinaryStream(int, InputStream)
method because it informs the driver that the parameter value should be sent to the server as aBLOB
. When thesetBinaryStream
method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as aLONGVARBINARY
or aBLOB
- Specified by:
setBlob
in interfacePreparedStatement
- 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:
SQLException
- if a database access error occurs, this method is called on a closedPreparedStatement
or ifparameterIndex
does not correspond to a parameter marker in the SQL statement
-
setBlob
Sets the designated parameter to a InputStream object.- Specified by:
setBlob
in interfacePreparedStatement
- Parameters:
parameterIndex
- index of the first parameter is 1, the second is 2, ...inputStream
