    NAME

    SPI_saveplan - save a plan
    

     

    SYNOPSIS

    void * SPI_saveplan(void * plan)
    
    
     

    DESCRIPTION

    SPI_saveplan saves a passed plan (prepared by SPI_prepare) in memory protected from freeing by SPI_finish and by the transaction manager and returns a pointer to the saved plan. This gives you the ability to reuse prepared plans in the subsequent invocations of your procedure in the current session. You may save the pointer returned in a local variable. Always check if this pointer is NULL or not either when preparing a plan or using an already prepared plan in SPI_execute_plan.  

    ARGUMENTS

    void * plan
    the plan to be saved
     

    RETURN VALUE

    Pointer to the saved plan; NULL if unsuccessful. On error, SPI_result is set thus:

    SPI_ERROR_ARGUMENT
    if plan is NULL
    SPI_ERROR_UNCONNECTED
    if called from an unconnected procedure

     

    NOTES

    If one of the objects (a table, function, etc.) referenced by the prepared plan is dropped during the session then the results of SPI_execute_plan for this plan will be unpredictable.
