Escaping the '\' (backslash) character

[brendonboshell]

It seems that using the Firebird.escape function replaces each backslash (\) with two backslash (\\) characters, for example:

console.log(firebirdEscape("hello\\world'\s"))
// Outputs: 'hello\\world''s'

However, this results in duplicate backslashes when inserted into the database. I am not too familiar with Firebird, but I understand we need to escape ' as '', but no escaping of backslashes is necessary.

Relevant line in escape

I am inclined to remove the escaping of \ and send a PR, but please let me know if there is some reason for this.

I'm not aware if this problem was solved in most recent versions but I'm facing this same issue when inserting escaped content (example: System File Paths).

Issue 1: Driver preserves js escaping when inserting content Expected behaviour: Don't preserve escaping.

Issue 2: Since drive preserves escaping. Each initial value is loaded from database as \\.

For example:

con.query('INSERT INTO T VALUES(?)', ['C:\\Program Files'].....

Using a DBMS to check the value, will reveal that value was not unespaced before being inserted. I would expect to see 'C:\Program Files' in my db field. Not 'C:\Program Files'

Then, If i pull that record from db. con.query('SELECT F FROM T',.....) // F will have the value of C:\\Program files

.... so on.

The only workaround I could found, for now, was to insert my text field as binary: Example:

let sql = `INSERT INTO T VALUES (X'${Buffer.from(data.ftpFolder).toString('hex')}'`
