Bug with SQL template variables when action inside while loop

[max-ostapenko]

When iterating an operation over the months I'm using while loop and a dynamic date variable in the SQL template.

I see something strange happens to the iterator variable within the SQL template.

Example:

let i = 0;
while (i <= 1) {
    operate(`while ${i}`).queries(ctx => `
        SELECT '${i}' AS value
    `);

    i++;
}

I get the following compiled SQLs:

1. Operation "while 0"

   SELECT '2' AS value

2. Operation "while 1"

   SELECT '2' AS value

• forEach and for loops work OK,
• without ctx => it works OK too.
