Interface ExecPreparedStatement

    • Method Detail

      • setSource

        void setSource​(java.lang.String txt)
        set the statement text
        Parameters:
        txt - the source text
      • getConstantAction

        ConstantAction getConstantAction()
        Get the Execution constants. This routine is called at Execution time.
        Returns:
        ConstantAction The big structure enclosing the Execution constants.
      • getSavedObject

        java.lang.Object getSavedObject​(int objectNum)
        Get a saved object by number. This is called during execution to access objects created at compile time. These are meant to be read-only at run time.
        Returns:
        Object A saved object. The caller has to know what it is requesting and cast it back to the expected type.
      • getSavedObjects

        java.util.List<java.lang.Object> getSavedObjects()
        Get all the saved objects. Used for stored prepared statements.
        Returns:
        a list with all the saved objects
      • getCursorInfo

        java.lang.Object getCursorInfo()
        Get the saved cursor info. Used for stored prepared statements.
        Returns:
        Object the cursor info
      • getActivationClass

        GeneratedClass getActivationClass()
                                   throws StandardException
        Get the class generated for this prepared statement. Used to confirm compatability with auxilary structures.
        Throws:
        StandardException - on error obtaining class (probably when a stored prepared statement is loading)
      • upToDate

        boolean upToDate​(GeneratedClass gc)
                  throws StandardException

        Checks whether this PreparedStatement is up to date and its activation class is identical to the supplied generated class. A call to upToDate(gc) is supposed to perform the same work as the following code in one atomic operation:

         getActivationClass() == gc && upToDate()
         
        Parameters:
        gc - a generated class that must be identical to getActivationClass() for this method to return true
        Returns:
        true if this statement is up to date and its activation class is identical to gc, false otherwise
        Throws:
        StandardException
        See Also:
        PreparedStatement.upToDate(), getActivationClass()
      • finish

        void finish​(LanguageConnectionContext lcc)
        Mark the statement as unusable, i.e. the system is finished with it and no one should be able to use it.
      • needsSavepoint

        boolean needsSavepoint()
        Does this statement need a savpoint
        Returns:
        true if needs a savepoint
      • getUpdateMode

        int getUpdateMode()
        the update mode of the cursor
        Returns:
        The update mode of the cursor
      • getTargetTable

        ExecCursorTableReference getTargetTable()
        the target table of the cursor
        Returns:
        target table of the cursor
      • hasUpdateColumns

        boolean hasUpdateColumns()
        Check if this prepared statement has a cursor with columns that can be updated.
      • isUpdateColumn

        boolean isUpdateColumn​(java.lang.String columnName)
        Check if the specified column name is one of the update columns.
      • setValid

        void setValid()
        set this prepared statement to be valid
      • setSPSAction

        void setSPSAction()
        Indicate that the statement represents an SPS action
      • getRequiredPermissionsList

        java.util.List<StatementPermission> getRequiredPermissionsList()
        Returns:

      • incrementExecutionCount

        int incrementExecutionCount()
        Increment and return the execution count for this statement.
        Returns:

                                long currentRowCount)
        Get the initial row count of the specified result set. If the initial row count has not yet been set, initialize it with the value of the current row count.
        Parameters:
        rsNum - the result set to get the initial row count for
        currentRowCount - the current row count for the result set
        Returns:
