SPI_execp

SPI_execp — execute a statement in read/write mode

Synopsis

int SPI_execp(SPIPlanPtr plan, Datum * values, const char * nulls, long count)

Description

SPI_execp is the same as SPI_execute_plan, with the latter’s `read_only parameter always taken as `false.

Arguments

+SPIPlanPtr +`+plan+`: prepared statement (returned by SPI_prepare)
+Datum * +`+values+`: An array of actual parameter values. Must have same length as the statement’s number of arguments.
+const char * +`+nulls+`: An array describing which parameters are null. Must have same length as the statement’s number of arguments. + If `nulls is `NULL then SPI_execp assumes that no parameters are null. Otherwise, each entry of the `nulls array should be `' ' if the corresponding parameter value is non-null, or 'n' if the corresponding parameter value is null. (In the latter case, the actual value in the corresponding `values entry doesn’t matter.) Note that nulls is not a text string, just an array: it does not need a `'\0' terminator.
+long +`+count+`: maximum number of rows to return, or 0 for no limit

Return Value

See SPI_execute_plan.

SPI_processed and SPI_tuptable are set as in SPI_execute if successful.
