db_foreach (public)

 db_foreach [ -dbn dbn ] statement_name sql [ args... ]

Defined in packages/acs-tcl/tcl/01-database-procs.tcl

Usage:

db_foreach statement-name sql [ -bind bind_set_id | -bind bind_value_list ] [ -column_array array_name | -column_set set_name ] code_block [ if_no_rows if_no_rows_block ]

Performs the SQL query sql, executing code_block once for each row with variables set to column values (or a set or array populated if -column_array or column_set is specified). If the query returns no rows, executes if_no_rows_block (if provided). In place of 'if_no_rows' also the 'else' keyword can be used.

Example:

db_foreach greeble_query "select foo, bar from greeble" {
        ns_write "<li>foo=$foo; bar=$bar\n"
    } if_no_rows {
        # This block is optional.
        ns_write "<li>No greebles!\n"
    }

Switches:
-dbn (optional)
The database name to use. If empty_string, uses the default database.
Parameters:
statement_name
