# SPI_getvalue — return the string value of the specified column
## Synopsis
```
char * SPI_getvalue(HeapTuple row, TupleDesc rowdesc, int colnumber)
```
## Description
`SPI_getvalue` returns the string representation of the value of the specified column.
The result is returned in memory allocated using `palloc`. (You can use `pfree` to release the memory when you don't need it anymore.)
## Arguments
**`HeapTuple row`**
input row to be examined **`TupleDesc rowdesc`**
input row description **`int colnumber`**
column number (count starts at 1)
## Return Value
Column value, or `NULL` if the column is null, `colnumber` is out of range (`SPI_result` is set to `SPI_ERROR_NOATTRIBUTE`), or no output function is available (`SPI_result` is set to `SPI_ERROR_NOOUTFUNC`).
