pg_select
submits a query
(SELECT statement) to the
PostgreSQL server and executes a given
chunk of code for each row in the result. The
commandString must be a
SELECT statement; anything else returns an
error. The arrayVar variable is an array
name used in the loop. For each row,
arrayVar is filled in with the row values,
using the column names as the array indices. Then the
procedure is executed.
In addition to the column values, the following special entries are made in the array:
A list of the column names returned by the query.
The number of columns returned by the query.
The current row number, starting at zero and incrementing for each iteration of the loop body.
The handle of the connection on which to execute the query.
The SQL query to execute.
An array variable for returned rows.
The procedure to run for each returned row.
