; If you have data which may potentially contain single ticks, you may wish
; to use the dialplan function SQL_ESC() to escape the data prior to its
; inclusion in the SQL statement.
+;
+;
+; The following variables are available in this configuration file:
+;
+; readhandle A comma-separated list of DSNs (from res_odbc.conf) to use when
+; executing the readsql statement. Each DSN is tried, in
+; succession, until the statement succeeds. You may specify up to
+; 5 DSNs per function class. If not specified, it will default to
+; the value of writehandle or dsn, if specified.
+; writehandle A comma-separated list of DSNs (from res_odbc.conf) to use when
+; executing the writesql statement. The same rules apply as to
+; readhandle. "dsn" is a synonym for "writehandle".
+; readsql The statement to execute when reading from the function class.
+; writesql The statement to execute when writing to the function class.
+; prefix Normally, all function classes are prefixed with "ODBC" to keep
+; them uniquely named. You may choose to change this prefix, which
+; may be useful to segregate a collection of certain function
+; classes from others.
+; escapecommas This option may be used to turn off the default behavior of
+; escaping commas which occur within a field. If commas are
+; escaped (the default behavior), then fields containing commas
+; will be treated as a single value when assigning to ARRAY() or
+; HASH(). If commas are not escaped, then values will be separated
+; at the comma within fields. Please note that turning this option
+; off is incompatible with the functionality of HASH().
; ODBC_SQL - Allow an SQL statement to be built entirely in the dialplan
[SQL]
dsn=mysql1
-read=${ARG1}
+readsql=${ARG1}
; ODBC_ANTIGF - A blacklist.
[ANTIGF]
-dsn=mysql1
-read=SELECT COUNT(*) FROM exgirlfriends WHERE callerid='${SQL_ESC(${ARG1})}'
+dsn=mysql1,mysql2 ; Use mysql1 as the primary handle, but fall back to mysql2
+ ; if mysql1 is down. Supports up to 5 comma-separated
+ ; DSNs. "dsn" may also be specified as "readhandle" and
+ ; "writehandle", if it is important to separate reads and
+ ; writes to different databases.
+readsql=SELECT COUNT(*) FROM exgirlfriends WHERE callerid='${SQL_ESC(${ARG1})}'
; ODBC_PRESENCE - Retrieve and update presence
[PRESENCE]
dsn=mysql1
-read=SELECT location FROM presence WHERE id='${SQL_ESC(${ARG1})}'
-write=UPDATE presence SET location='${SQL_ESC(${VAL1})}' WHERE id='${SQL_ESC(${ARG1})}'

- ; field may be separated into individual variables with ARRAY.
