[encode_sqlfull]

Description

Alternative to encode_sql that also deals with escaping % and _ so that the resulting string can be safely used when creating sql queries with LIKE sections.
See Bil Corrys talk from LDC Chicago 2008: All Your Base Are Belong To Us

Only needed when dealing with SQL queries using LIKE statements (or any of the other pattern- matching queries that recognize “%” and “_”).

Sample Usage

var(sql = 'SELECT * 
FROM mydb.mytable 
WHERE
myfield LIKE "' + encode_sqlfull(action_param('myvalue')) + '%"')
