Question

My SQL script works successfully in MySQL Workbench.

The following gives an error:

$link = mysqli_connect(***********);
$result = $link->query($sql);

The SQL script performs some actions including:

• create temporary table
• truncate table
• drop table
• insert
• select

I am getting an error when executing this:

-- 1.1 Creating temporary table for categories

    drop table if exists exp_categories; -- just in case
    create temporary table exp_categories
    (
        ID bigint not null,
        Categories text not null,
        PRIMARY KEY (ID)
    ) DEFAULT CHARSET=utf8;

-- 1.2 Inserting data...
-- few other statements here
-- last statement is SELECT

Does mysqli have limitations that I am encountering?

Answer 1

Try to use multi_query()

Multiple statements or multi queries must be executed with
mysqli_multi_query(). The individual statements of the statement
string are separated by semicolon.

$link->multi_query($sql)

And the user you connect with have to have necessary privileges in your db or global privileges.
