From ahmed101's interpretation of your requirement:
Code:
for file in *.csv; do sed -i "s/^/`basename $file .csv`_sqd,/" $file; done

Going by your original idea:
Code:
#! /bin/bash

spname=(199906_sqd 199907_sqd 199908_sqd 199909_sqd 199910_sqd 200005_sqd 200006_qd 200007_sqd \
200008_sqd 200009_sqd 200010_sqd 200011_sqd 200101_sqd 200102_sqd 200105_sqd 200106_sqd \
200107_sqd 200112_sqd 200201_sqd 200202_sqd 200206_sqd 200207_sqd 200212_sqd 200301_sqd \
200302_sqd 200306_sqd 200307_sqd 200311_sqd 200312_sqd 200401_sqd 200402_sqd 200405_sqd \
200406_sqd 200501_sqd 200502_sqd 200506_sqd 200601_sqd 200602_sqd 200606_sqd 200705_sqd \
200706_sqd 200707_sqd)

for x in ${spname[@]}
do
    sed -i "s/^/$x,/" `echo $x | cut -d_ -f1`.csv
done

locale::codes::langext5.18

Locale::Codes::LangExt(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangExt(3pm)

NAME

       Locale::Codes::LangExt - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangExt;

	  $lext = code2langext('acm');		       # $lext gets 'Mesopotamian Arabic'
	  $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langext_codes();
	  @names   = all_langext_names();

DESCRIPTION

       The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language extensions. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langext('acm','alpha');
	  $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic.

	   This is the default code set.

ROUTINES

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
