预准备语句上的语法错误

Question

I have this query

$q1 = "UPDATE klanten SET (
       kla_tel2,
       kla_mobiel,
       kla_fax,
       kla_btw_nummer,
       kla_bankrekening,
       kla_ww,
       kla_bez_straat,
       kla_bez_nummer,
       kla_bez_toev,
       kla_bez_pc,
       kla_bez_plaats,
       kla_bez_land_id,
       kla_post_straat,
       kla_post_nummer,
       kla_post_toev,
       kla_post_postbus,
       kla_post_pc,
       kla_post_plaats,
       kla_post_land_id,
       kla_fac_straat,
       kla_fac_nummer,
       kla_fac_toev,
       kla_fac_postbus
       kla_fac_pc,
       kla_fac_plaats,
       kla_fac_land_id,
       kla_sidn_owner,
       kla_reg_status,
       kla_rechtspersoon
       )
       VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)
       WHERE kla_id=" . $kla_id;

But when executed it gives me a syntax error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '( kla_tel2, kla_mobiel, kla_fax, kla_btw_num' at line 1: SQL: UPDATE klanten SET ...

What I know is that all values are filled and that $kla_id is filled too, but as this is a SQL Syntax error that shouldn't be a problem.

EDIT

MySql Client Version is 5.0.51a Server Version is 5.0.51a-24+lenny4 Protocol version is 10

Answer 1

You're using the wrong UPDATE syntax. Please see the docs for more info.

The right syntax looks like:

UPDATE klanten SET kla_tel2 = <some_value>, kla_mobiel = <some_other_value> WHERE kla_id = <some_third_value>

You can also use this with prepared SQL statements like your example above, using question marks.
