prim__prepareStmt : AnyPtr -> String -> PrimIO AnyPtr

  Prepare a SQL statement.
  
  Parameters:
  
  * Oracle connection handle

  Returns:
  
  * Raw dpiStmt pointer
  * NULL on failure
  

prim__releaseStmt : AnyPtr -> PrimIO ()

  Execute a prepared statement.
  
  Returns:
  * 0 on success.
  * non-zero on failure.
  

prim__fetch : AnyPtr -> PrimIO Int32

  Fetch the next row from a query result.
  
  Returns:
  * 1 if a row was fetched.
  * 0 if no rows remain.
  * negative value on error.
  

prim__columnCount : AnyPtr -> PrimIO Int32

  Retrieve the number of columns in the statement result set.
  

prim__columnValue : AnyPtr -> Int32 -> PrimIO AnyPtr

  Retrieve the current row value for a column.
  
  This interface is not sufficient for a production-quality Oracle driver.
  Oracle values should be marshalled through type-specific accessors instead.
