## 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.
