dp_build_sql_structs

one of the documented procedures in this installation of the ACS
Usage:
dp_build_sql_structs   { form_index "" }
What it does:
Upvars to get the $dp_form ns_set, and builds a bunch of dp_sql_structs that will perform the SQL necessary to process all the dp_form variables prefixed by "dp$form_index". The return value is an ns_set where key is table name and value is a dp_sql_struct. Arguments: form_index - The only items in the $dp_form ns_set that get processed are the ones whose keys are of the form "dp_form$form_index.*"
Defined in: /web/philip/tcl/data-pipeline-defs.tcl

Source code:



    upvar dp_form dp_form

    set dp_sql_structs [ns_set new]
    foreach var [dp_list_packed_vars $form_index] {
        set varname_parts [split $var .]

        set table_name [lindex $varname_parts 1]
        set col_name   [lindex $varname_parts 2]
        set datatype   [lindex $varname_parts 3]

	if {![info exists table_sql_struct.$table_name]} {
	    set table_sql_struct.$table_name [dp_sql_struct_new]
	    ns_set put $dp_sql_structs $table_name  [set table_sql_struct.$table_name]
	    set found_some_p 1
	}

	dp_add_one_col_to_sql_struct [set table_sql_struct.$table_name] $col_name [dp_formvalue $var] $datatype

    }

    if [info exists found_some_p] {
        return $dp_sql_structs
    } else {
        return
    }
