Conditional update/insert in MySQL -


i found here topic mysql if, else query,i adapted can't figure out problem it.

here query:

if (select * `jos_import03_07_2011` `cod_oem` = 'op-4cl') null  insert `jos_import03_07_2011` (`tip_imp`, `tip_produs`, `producator`,     `cod_intern`, `desc`, `cod_oem`, `pret`, `valuta`) values ('imprimanta laser',      'piese schimb', 'brother', 'br-200503', '', 'op-4cl', '338.49', 'eur');  else update `jos_import03_07_2011` set `pret` = '338.49' `cod_oem` = 'op-4cl'; end if;

and here error:

you have error in sql syntax; check manual corresponds mysql      server version right syntax use near 'if (select *    `jos_import03_07_2011` `cod_oem` = 'op-4cl') null the' @ line 1

this original post:

conditional mysql statement. if true update, if false insert

thanks, sebastian

update

error code if exists:

you have error in sql syntax; check manual corresponds mysql  server version right syntax use near 'if exists (select *  `jos_import03_07_2011` `cod_oem` = 'op-4cl') then' @ line 1

any reason can't use insert ... on duplicate key syntax?

insert `jos_import03_07_2011` (`tip_imp`, `tip_produs`, `producator`,     `cod_intern`, `desc`, `cod_oem`, `pret`, `valuta`) values ('imprimanta laser', piese schimb', 'brother', 'br-200503', '', 'op-4cl', '338.49', 'eur') on duplicate key update set pret = values(pret)

would far more efficient: 1 less query , far less code debug.
