SPI_getbinval

SPI_getbinval — return the binary value of the specified column

Synopsis

Datum SPI_getbinval(HeapTuple row, TupleDesc rowdesc, int colnumber,
                    bool * isnull)

Description

SPI_getbinval returns the value of the specified column in the internal form (as type Datum).

This function does not allocate new space for the datum. In the case of a pass-by-reference data type, the return value will be a pointer into the passed row.

Arguments

`HeapTuple +`_`+row`_: input row to be examined
`TupleDesc +`_`+rowdesc`_: input row description
`int +`_`+colnumber`_: column number (count starts at 1)
`bool * +`_`+isnull`_: flag for a null value in the column

Return Value

The binary value of the column is returned. The variable pointed to by `isnull` is set to true if the column is null, else to false.

SPI_result is set to SPI_ERROR_NOATTRIBUTE on error.
