Summary:                    Problem with Like query on MS SQL
Description: 
The problem is the MSSQL server does not support back slash "\" as escape
character on select queries hence when you execute 

SELECT * FROM extensions WHERE exten LIKE '\_%' AND context = 'default'
AND priority = '1' ORDER BY exten

is not working. The correct and most commonly used syntax is

SELECT * FROM extensions WHERE exten LIKE '[_]%' AND context = 'default'
AND priority = '1' ORDER BY exten

As far as I concern this is compatible with mySQL and PostgreSQL.

The solution I propose is to change the line 

cfg = ast_load_realtime_multientry(table, "exten LIKE", "\\_%", "context",
context, "priority", pri, NULL);

at pbx_realtime.c to 

cfg = ast_load_realtime_multientry(table, "exten LIKE", "[_]%", "context",
context, "priority", pri, NULL);

Did you set

backslash_is_escape => no

in res_odbc.conf, as is now documented that you need to do in the sample
config?
