SPI_execp

Name

SPI_execp -- execute a plan 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

execution plan (returned by SPI_prepare)

Datum * values

An array of actual parameter values. Must have same length as the plan's number of arguments.

const char * nulls

An array describing which parameters are null. Must have same length as the plan's number of arguments. 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.

long count

maximum number of rows to process or return

Return Value

See SPI_execute_plan.

SPI_processed and SPI_tuptable are set as in SPI_execute if successful.
