The columns are separated by tab (Not in examples). I have 63 combinations of Col1/Col2 (50/1, 50/5 .... ) so hard coding is not a solution. Col3 is not in use so can ignore
Thanks in advance

Please use code tags, thanks. code and quote tags are different. quote tags are for quoting what other people wrote, code tags is for code, data or logs etc.

hi,
I have a requirement where in I read the values from a file using awk. The resulting data should be converted into row format from column format.
For ex: My log file login.lst contains the following
SERVER1 DB1
SERVER2 DB2
SERVER3 DB3
SERVER4 DB4
I use awk to grep only the server... (6 Replies)
Getting tired of cut-and-paste...so I thought I would post a question.
how do I change this column output to a single row?
from this:
# vgdisplay -v /dev/vgeva05 | grep dsk | awk '{print $3}'
/dev/dsk/c6t0d5
/dev/dsk/c11t0d5
/dev/dsk/c15t0d5

Hi all!
I have this kind of output:
a1|b1|c1|d1|e1
a2|b2|c2
a3|b3|c3|d3
I would like to transpose columns d and e (when they exist) in column c, and under the row where they come from.
Then copying the beginning of the row.
In order to obtain:
a1|b1|c1
a1|b1|d1
a1|b1|e1
a2|b2|c2... (1 Reply)

spi_modifytuple
SPI_MODIFYTUPLE(3) PostgreSQL 9.2.7 Documentation SPI_MODIFYTUPLE(3)NAME
SPI_modifytuple - create a row by replacing selected fields of a given row
SYNOPSIS
HeapTuple SPI_modifytuple(Relation rel, HeapTuple row, int ncols,
int * colnum, Datum * values, const char * nulls)
DESCRIPTION
SPI_modifytuple creates a new row by substituting new values for selected columns, copying the original row's columns at other positions.
The input row is not modified.
ARGUMENTS
Relation rel
Used only as the source of the row descriptor for the row. (Passing a relation rather than a row descriptor is a misfeature.)
HeapTuple row
row to be modified
int ncols
number of column numbers in the array colnum
int * colnum
array of the numbers of the columns that are to be changed (column numbers start at 1)
Datum * values
new values for the specified columns
const char * Nulls
which new values are null, if any (see SPI_execute_plan for the format)
RETURN VALUE
new row with modifications, allocated in the upper executor context; NULL only if row is NULL
On error, SPI_result is set as follows:
SPI_ERROR_ARGUMENT
if rel is NULL, or if row is NULL, or if ncols is less than or equal to 0, or if colnum is NULL, or if values is NULL.
SPI_ERROR_NOATTRIBUTE
if colnum contains an invalid column number (less than or equal to 0 or greater than the number of column in row)
