Name

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.
