Class NamedParameterStatement


  • public class NamedParameterStatement
    extends java.lang.Object
    The input properties parameter statement for JDBC that is prepared and filled with the parameters from the named host variables as specified in the Database connector com.iziix.db.prop.InputProps with the com.iziix.db.prop.InputVariable's containing mappings to VSField's.

    This class wraps around a PreparedStatement and enables iizi SQL statement preparation. It also makes it easier for the com.iziix.db.api.IQueryStatementInput custom processor to set their values as required.

      • setObject

        public void setObject​(java.lang.String name,
                              java.lang.Object x)
                       throws java.sql.SQLException
        Sets the value of the designated parameter using the given object.

        The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument 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. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, RowId, SQLXML or Array, the driver should pass it to the database as a value of the corresponding SQL type.

        Note: Not all databases allow for a non-typed Null to be sent to the backend. For maximum portability, the setNull or the setObject(int parameterIndex, Object x, int sqlType) method should be used instead of setObject(int parameterIndex, Object x).

        Note: This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

        Parameters:
        name - The name of the parameter.
        x - The object containing the input parameter value.
        Throws:
        java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or the type of the given object is ambiguous.
        NamedParameterException - if the parameter does not exist.
      • setDate

        public void setDate​(java.lang.String name,
                            java.sql.Date x,
                            java.util.Calendar cal)
                     throws java.sql.SQLException
        Sets the designated parameter to the given java.sql.Date value, using the given Calendar object. The driver uses the Calendar object to construct an SQL DATE value, which the driver then sends to the database. With a Calendar object, the driver can calculate the date taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
        Parameters:
        name - The name of the parameter.
        x - The parameter value.
        cal - The Calendar object the driver will use to construct the date.
        Throws:
        java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement.
        NamedParameterException - if the parameter does not exist.
      • setTime

        public void setTime​(java.lang.String name,
                            java.sql.Time x,
                            java.util.Calendar cal)
                     throws java.sql.SQLException
        Sets the designated parameter to the given java.sql.Time value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIME value, which the driver then sends to the database. With a Calendar object, the driver can calculate the time taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
        Parameters:
        name - The name of the parameter.
        x - The parameter value.
        cal - The Calendar object the driver will use to construct the time.
        Throws:
        java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement.
        NamedParameterException - if the parameter does not exist.
      • setTimestamp

        public void setTimestamp​(java.lang.String name,
                                 java.sql.Timestamp x,
                                 java.util.Calendar cal)
                          throws java.sql.SQLException
        Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a Calendar object, the driver can calculate the timestamp taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
        Parameters:
        name - The name of the parameter.
        x - The parameter value.
        cal - The Calendar object the driver will use to construct the timestamp.
        Throws:
        java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement.
        NamedParameterException - if the parameter does not exist.
      • setNull

        public void setNull​(java.lang.String name,
                            int sqlType,
                            java.lang.String typeName)
                     throws java.sql.SQLException
        Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

        Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it.

        Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.

        Parameters:
        name - The name of the parameter.
        sqlType - A value from java.sql.Types.
        typeName - The fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or REF.
        Throws:
        java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement.
        java.sql.SQLFeatureNotSupportedException - if sqlType is a ARRAY, BLOB, CLOB, DATALINK, JAVA_OBJECT, NCHAR, NCLOB, NVARCHAR, LONGNVARCHAR, REF, ROWID, SQLXML or STRUCT data type and the JDBC driver does not support this data type or if the JDBC driver does not support this method.
        NamedParameterException - if the parameter does not exist.
      • setURL

        public void setURL​(java.lang.String name,
                           java.net.URL x)
                    throws java.sql.SQLException
        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.
        Parameters:
        name - The name of the parameter.
        x - The java.net.URL object to be set.
        Throws:
        java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs or this method is called on a closed PreparedStatement.
        java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support this method.
        NamedParameterException - if the parameter does not exist.
      • setObject

        public void setObject​(java.lang.String name,
                              java.lang.Object x,
                              int targetSqlType,
                              int scaleOrLength)
                       throws java.sql.SQLException
        Sets the value of the designated parameter with the given object. If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the prepared statement is executed.

        The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, NClob, Struct, java.net.URL, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

        Note that this method may be used to pass database-specific abstract data types.

        Parameters:
        name - The name of the parameter.
        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.
        scaleOrLength - For java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For Java Object types InputStream and Reader, this is the length of the data in the stream or reader. For all other types, this value will be ignored.
        Throws:
        java.sql.SQLException - if parameterIndex does not correspond to a parameter marker in the SQL statement; if a database access error occurs; this method is called on a closed PreparedStatement or if the Java Object specified by x is an InputStream or Reader object and the value of the scale parameter is less than zero
        java.sql.SQLFeatureNotSupportedException - if the JDBC driver does not support the specified targetSqlType
        NamedParameterException - if the parameter does not exist.

                       throws java.sql.SQLException
        Sets the value of the designated parameter with the given object.

        If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the prepared statement is executed.
