static

Perform a single sqlippool query.

Mostly wrapper around sql_query which does some special sqlippool sequence substitutions and expands the format string.

Parameters

fmt	sql query to expand.
handle	sql connection handle.
data	Instance of rlm_sqlippool.
request	Current request.
param	ip address string.
param_len	ip address string len.

Returns

• 0 on success.
• < 0 on error.
