DESCRIPTION

DBIx::Printf::Named is a named-printf-style prepared statement. It adds a nprintf method to DBI::db package. This module is based on DBIx::Printf by kazuho oku.

nprintf(stmt, { key1 => value1, key2 => value2 })

Builds a SQL statement from given statement with placeholders and values. Following placeholders are supported.

  %(key)d         - integer
  %(key)f         - floating point
  %(key)s         - string
  %(key)t         - do not quote, pass thru
  %like(fmt) - formats and quotes a string for like expression

%like example

Below is an example of using the %%like placeholder. Since metacharacters of supplied parameters are escaped, the example would always by a prefix search.

  $dbh->printf('select * from t where name like %like(%(name)s%%)', { name => $name });
