Method Detail

prepareCall

public java.sql.CallableStatement prepareCall()
                                       throws java.sql.SQLException

Prepares the statement and registers the OUT/INOUT parameters (if any).

Returns:

CallableStatement

Throws:

java.sql.SQLException

prepareCall

public java.sql.CallableStatement prepareCall(PyObject rsType,
                                              PyObject rsConcur)
                                       throws java.sql.SQLException

Prepares the statement and registers the OUT/INOUT parameters (if any).

Parameters:

rsType - the value of to be created ResultSet type

rsConcur - the value of the to be created ResultSet concurrency

Returns:

CallableStatement

Throws:

java.sql.SQLException

normalizeInput

public void normalizeInput(PyObject params,
                           PyObject bindings)
                    throws java.sql.SQLException

Prepare the binding dictionary with the correct datatypes.

Parameters:

params - a non-None list of params

bindings - a dictionary of bindings

Throws:

java.sql.SQLException

isInput

public boolean isInput(int index)
                throws java.sql.SQLException

This method determines whether the param at the specified index is an IN or INOUT param for a stored procedure. This is only configured properly AFTER a call to normalizeInput().

Parameters:

index - JDBC indexed column index (1, 2, ...)

Returns:

true if the column is an input, false otherwise

Throws:

java.sql.SQLException

toSql

public java.lang.String toSql()
                       throws java.sql.SQLException

Returns the call in the syntax:

{? = call (?, ?, ...)} {call (?, ?, ...)}

As of now, all parameters variables are created and no support for named variable calling is supported.

Returns:

String

Throws:

java.sql.SQLException
