Detailed Description

Function Documentation

hash Qore::Pgsql::pgsql_bind	(	softint	type,
		any	value
	)

Creates a hash data structure understood by the pgsql DBI driver when binding values in SQL queries that allows programmers to directly specify the PostgreSQL data type for the bind.

Use the Type Constants for pgsql_bind() to specify the PostgreSQL data type for the bind. If the value to bind is NOTHING or NULL, a NULL will be bound as the value, regardless of the PostgreSQL type code provided as the first argument

Code Flags:

RET_VALUE_ONLY

Parameters

type	the type code for the PostgreSQL type to bind
value	the value to bind

Returns

The hash returned by the function encodes the desired PostgreSQL type for the bind and the value for binding in the "^pgtype^" and "^value^" keys

Example:

# we use pgsql_bind() to bind a money type by value, otherwise the server would raise an error
my float $amount = 400.56;
my *hash $results = $db.select("select * from table where amount > %v", pgsql_bind(PG_TYPE_CASH, $amount));

Exceptions

PGSQL-BIND-ERROR

if the type argument is 0 this exception is raised
