Sinopse
int SPI_execp(void * plan, Datum * values, const char * nulls, int count)
Descrição
SPI_execp executes a plan prepared by SPI_prepare. tcount has the same interpretation as in SPI_exec.
Argumentos
- void * plan
-
execution plan (returned by
SPI_prepare)
- Datum *values
-
actual parameter values
- const char * nulls
-
An array describing which parameters are null. n indicates a null value (entry in values will be ignored); a space indicates a nonnull value (entry in values is valid).
If nulls is NULL then
SPI_execp assumes that no parameters are null.
- int count
-
number of row for which plan is to be executed
Valor retornado
The return value is the same as for SPI_exec or one of the following:
- SPI_ERROR_ARGUMENT
-
if plan is NULL or count is less than 0
- SPI_ERROR_PARAM
-
if values is NULL and plan was prepared with some parameters
SPI_processed and SPI_tuptable are set as in SPI_exec if successful.
Observações
If one of the objects (a table, function, etc.) referenced by the prepared plan is dropped during the session then the result of SPI_execp for this plan will be unpredictable.
