public interface OraclePreparedStatement
This interface defines the Oracle extensions to the standard JDBC interface
java.sql.PreparedStatement
. You can use
java.sql.PreparedStatement
in your application where you do not
make use of the Oracle extensions. However, when your application uses the
Oracle extensions to java.sql.PreparedStatement
you must cast
your prepared statement object to the type
oracle.jdbc.OraclePreparedStatement
. Although the type by which
the java compiler will identify the statement object is changed, the object
itself is unchanged.
Extended functionality consists of setXXX()
methods for
binding oracle.sql.
types and objects into prepared statements,
and methods to support Oracle performance extensions on a
statement-by-statements basis.
About prepared statements : To write changes to the database, such
as for INSERT
or UPDATE
operations, you will
typically create a PreparedStatement
object. This allows you to
execute a statement with varying sets of input parameters. The
prepareStatement()
method of your JDBC Connection
object allows you to define a statement that takes variable bind parameters,
and returns a JDBC PreparedStatement
object with your statement
definition.
Bind your data : Use setXXX()
methods on the
PreparedStatement
object to bind data into the prepared
statement to be sent to the database. Again, some of these methods are Oracle
specific and require that you cast your PreparedStatement
object
to the OraclePreparedStatement
type.
For example, if you have a Connection
object named
conn
and a RAW named my_raw
, then write the RAW
to the database as follows:
PreparedStatement ps = conn.prepareStatement ("INSERT INTO raw_table VALUES(?)"); ((OraclePreparedStatement)ps).setRAW(1, my_raw); ps.execute();
Connection.prepareStatement

void defineParameterTypeBytes(int param_index, int type, int max_size) throws java.sql.SQLException
Similarly to defineColumnType()
. Before executing a Query
you may choose to inform JDBC of the type and maximum length of the bind
parameter. If not, based on the setXXX
call, the maximum
length of the type is taken, i.e., for a setString a 4k buffer is
allocated. This API does not reduce the network round trip. It is purely a
memory optimization API.
Note: You should use OracleTypes.CHAR
as the type
value if you are going bind later as setCHAR
and use
OracleTypes.VARCHAR
if you are going to bind as
setString
for effective results.
param_index
- Index of bind parameter (should be >=0)type
- Type to be assigned to bind parameter.
This type could be different from the
native type of the column. Appropriate
conversions will be done.max_size
- Maximum length of bind data in bytes
(should be >=0)

int getExecuteBatch()
To set the batch value for this statement, you can use the
setExecuteBatch
method. You can also set a default batch value
with the OracleConnection.setDefaultExecuteBatch
.
OracleConnection.setDefaultExecuteBatch
,
setExecuteBatch
int sendBatch() throws java.sql.SQLException
This method flushes any batched executions before the batch value is
reached. Executions normally happen when the number of executions reaches
the batch value, which is set via the setExecuteBatch
method.
It does not do anything if the statement does not use the Oracle batching
model.
java.sql.SQLException
- if an error occurredvoid setARRAY(int parameterIndex, ARRAY arr) throws java.sql.SQLException
oracle.sql.ARRAY
.
parameterIndex
- the first parameter is 1, the second is 2, ...arr
- the parameter value
java.sql.SQLException
- if a database access error occursvoid setBfile(int parameterIndex, BFILE file) throws java.sql.SQLException
oracle.sql.BFILE
value.
Note: This is the same as setBFILE
.
parameterIndex
- the first parameter is 1, the second is 2, ...file
- the parameter value
java.sql.SQLException
- if a database access error occurssetBFILE
void setBFILE(int parameterIndex, BFILE file) throws java.sql.SQLException
oracle.sql.BFILE
value.
Note: An instance of the oracle.sql.BFILE
class
contains only the locator of the BFILE, not the data. Thus, this method
binds the designated parameter to a BFILE locator not to the data.
For example, assume you want to insert a BFILE locator into a table, and
you have an OraclePreparedStatement
object ops
to
insert data into a table. The first column is a string (to designate a row
number), the second column is a BFILE, and you have a valid
oracle.sql.BFILE
object (bfile
). Write the BFILE
to the database as follows:
OraclePreparedStatement ops = (OraclePreparedStatement)conn.prepareStatement ("INSERT INTO my_bfile_table VALUES(?,?)"); ops.setString(1, "one"); ops.setBFILE(2, bfile); ops.execute();
This stores only the locator of the BFILE in the
my_bfile_table
. See the BFILE
class to get more details
about how to deal with the data.
parameterIndex
- the first parameter is 1, the second is 2, ...file
- the parameter value
java.sql.SQLException
- if a database access error occursvoid setBLOB(int parameterIndex, BLOB lob) throws java.sql.SQLException
oracle.sql.BLOB
value.
Note: An instance of the oracle.sql.BLOB
class
contains only the locator of the BLOB, not the data. Thus, this method
binds the designated parameter to a BLOB locator not to the data.
For example, if you have an OraclePreparedStatement
object
ops
and a BLOB named my_blob
, then write the BLOB
to the database as follows:
OraclePreparedStatement ops = (OraclePreparedStatement)conn.prepareStatement ("INSERT INTO blob_table VALUES(?)"); ops.setBLOB(1, my_blob); ops.execute();
This stores only the locator of the BLOB in the
clob_table
. Use the method BLOB.getBinaryOutputStream
to write data to a BLOB.
parameterIndex
- the first parameter is 1, the second is 2, ...lob
- the parameter value
java.sql.SQLException
- if a database access error occursvoid setCHAR(int parameterIndex, CHAR ch) throws java.sql.SQLException
oracle.sql.CHAR
value.
setCHAR
checks the character set of the argument. If it is
not the same as the network character set, then the bytes of the argument
are converted to the network character set and those bytes are sent to the
database. The conversion between the argument character set and the network
character set is via the Universal Character Set (UCS2). That is, the
argument is converted to UCS2, then the UCS2 bytes are converted to the
network character set.
Note: If an input character does not have a representation in
UCS2, or if the UCS2 does not have a representation of the network
character set, setCHAR
will throw an exception.
parameterIndex
- the first parameter is 1, the second is 2, ...ch
- the parameter value
java.sql.SQLException
- if a database access error occurssetFixedChar
void setCLOB(int parameterIndex, CLOB lob) throws java.sql.SQLException
oracle.sql.CLOB
value.
Note: An instance of the oracle.sql.CLOB
class
contains only the locator of the CLOB, not the data. Thus, this method
binds the designated parameter to a CLOB locator not to the data.
For example, if you have an OraclePreparedStatement
object
ops
and a CLOB named my_clob
, then write the CLOB
to the database as follows:
OraclePreparedStatement ops = (OraclePreparedStatement)conn.prepareStatement ("INSERT INTO clob_table VALUES(?)"); ops.setCLOB(1, my_clob); ops.execute();
This stores only the locator of the CLOB in the
clob_table
. Use the methods CLOB.getCharacterOutputStream
or CLOB.getAsciiOutputStream
to write data to a CLOB.
parameterIndex
- the first parameter is 1, the second is 2, ...lob
- the parameter value
java.sql.SQLException
- if a database access error occursvoid setCursor(int parameterIndex, java.sql.ResultSet rs) throws java.sql.SQLException
java.sql.ResultSet
. This
is used for RefCursor parameter only.
NOTE: The method is a misnomer. You should use CURSOR only in callable statements.

void setCustomDatum(int parameterIndex, CustomDatum x) throws java.sql.SQLException
oracle.sql.CustomDatum
value.
In the 9i release the oracle.sql.CustomDatum
has been
deprecated and replaced by the oracle.sql.ORAData
interface. For this reason, this method is also deprecated. It is
recommended to use setORAData()
instead.

java.sql.SQLException
- if a database access error occursvoid setExecuteBatch(int batchValue) throws java.sql.SQLException
The Oracle update batching model allows you to "batch" multiple executions of a single statement with different bind variables. Actual execution happens when the number of batched executions reaches the "batch value", which is set by this method.
The batch value for this prepared statement can be set at any time via
this method. Changing the batch value will affect all future executes. You can
also use OracleConnection.setDefaultExecuteBatch
to set a
default batch value.
The batch value will automatically be set to 1 by the driver if any of
the bind types is of type stream. This overrides any value that the user
might have set. Binds that were performed before any

String
and executes a
non-padded comparison with a SQL CHAR.
CHAR data in the database is padded to the column width. This leads to a
limitation in using the setCHAR()
method to bind character
data into the WHERE
clause of a SELECT
statement--the character data in the WHERE
clause must also be
padded to the column width to produce a match in the SELECT
statement. This is especially troublesome if you do not know the column
width.
setFixedCHAR()
remedies this. This method executes a
non-padded comparison.
Notes:

to use the setFixedCHAR()
method.The following example demonstrates the difference between the
setString()
, setCHAR()
and
setFixedCHAR()
methods.
// Schema is : create table my_table (col1 char(10)); // insert into my_table values ('JDBC'); PreparedStatement pstmt = conn.prepareStatement ("select count() from my_table where col1 = ?"); ResultSet rs; pstmt.setString (1, "JDBC"); // Set the Bind Value rs = pstmt.executeQuery(); // This does not match any row // ... do something with rs CHAR ch = new CHAR("JDBC ", null); ((OraclePreparedStatement)pstmt).setCHAR(1, ch); // Pad it to 10 bytes rs = pstmt.executeQuery(); // This matches one row // ... do something with rs ((OraclePreparedStatement)pstmt).setFixedCHAR(1, "JDBC"); rs = pstmt.executeQuery(); // This matches one row // ... do something with rs

Note that with the JDBC standard setFloat API the float data is converted to server internal NUMBER format before being sent to the server. In Oracle the SQL REAL, FLOAT, and DOUBLE PRECISION datatypes are NUMBER types.
The connection property SetFloatAndDoubleUseBinary causes the setFloat API to use binary conversion.
Binary conversion sent to a BINARY_FLOAT parameter is fast and bit exact. Binary conversion sent to a NUMBER parameter moves CPU load to the server but the data will be the same as NUMBER conversion on the client.
NUMBER conversion sent to a NUMBER parameter is correct and keeps the CPU load on the client. NUMBER conversion sent to a BINARY_FLOAT parameter is not bit exact and has extra CPU load on both client and server

can be a Java primitive type array such as int[] or a Java object array such as
BigDecimal[].maxLen
- This argument specifies the maximum table length of the
index-by table bind value which defines the maximum possible curLen for batch
updates. For standalone binds, maxLen should use the same value as curLen. This
argument is required.curLen
- This argument specifies the actual size of the index-by table
bind value in arrayData. If the curLen value is smaller than the size of
arrayData, only the curLen number of table elements is passed to the
database. If the curLen value is larger than the size of arrayData, the entire
arrayData is sent to the database.elemSqlType
- This argument specifies the index-by table element type
based on the values defined in the OracleTypes class.elemMaxLen
- This argument specifies the index-table element maximum
length in case the element type is CHAR, VARCHAR, or RAW. This value is ignored
for other types. A value of 0 for elemMaxLen would inidicate the driver

- if a database access error occursvoid setFormOfUse(int parameterIndex, short formOfUse)
FORM_CHAR
for SQL CHAR
datatypes and FORM_NCHAR
for SQL NCHAR datatypes, where
FORM_CHAR
is the default. If the "form of use" is set to
FORM_NCHAR
, the JDBC driver will represent the provided data
in the national character set of the server.
The usage of SQL NCHAR datatypes is similar to that of the SQL CHAR
(CHAR
, VARCHAR2
, and CLOB
)
datatypes. JDBC uses the same classes and methods to access SQL NCHAR
datatypes that are used for the corresponding SQL CHAR
datatypes. Therefore, there are no separate, corresponding classes defined
in the oracle.sql
package for SQL NCHAR datatypes. Likewise,
there is no separate, corresponding constant defined in the
oracle.jdbc.OracleTypes
class for SQL NCHAR datatypes. The
only difference in usage between the two datatypes occur in a data bind
situation: a JDBC program must call the setFormOfUse()
method
to specify if the data is bound for a SQL NCHAR datatype.
In order to put this method in effect, you must invoke this method
before setXXX()
and registerOutParameter()
for
the column.
The following code shows how to access SQL NCHAR data:
// // Table TEST has the following columns: // - NUMBER // - NVARCHAR2 // - NCHAR // oracle.jdbc.OraclePreparedStatement pstmt = (oracle.jdbc.OraclePreparedStatement) conn.prepareStatement("insert into TEST values(?, ?, ?)"); // oracle.jdbc.OraclePreparedStatement.FORM_NCHAR should be used for all NCHAR, // NVARCHAR2 and NCLOB data types. pstmt.setFormOfUse(2, FORM_NCHAR); pstmt.setFormOfUse(3, FORM_NCHAR); pstmt.setInt(1, 1); // NUMBER column pstmt.setString(2, myUnicodeString1); // NVARCHAR2 column pstmt.setString(3, myUnicodeString2); // NCHAR column pstmt.execute();
