Variable can't contain backslash

[chitly]

This is an example code.

const text = 'abc\\';
await client.execute('insert into users(name) values(?)', [text]);

This is a result of the query string.

insert into users(name) values("abc\")

So, it will throw an error.

@chitly Thanks chitly, it's a really good issue.
@manyuanrong @zhmushan It should be an escape issue. Since this lib depends on module sql_builder, I prefer to handle such issue in that module. Thoughts?

[manyuanrong]

I think it needs to be handled in sql_builder, and if the value ends with "", it can be very violent to directly add a "" at the end

I've raised a pull request to fix this in sql-builder
