Hi Experts,

When executing a query runtime in Delphi which contains a " ' " (single quote) I terminates the query in gives an error?
What is the correct why of working with params which contains a ' ?

If not mistaken I am looking for something similar than PHP's stripslashes().

Thanks in advance!

If the content of the query is under complete control of the code, use TWO single quotes within the string, as in:

Qry.SQL.Text := 'It doesn''t matter';

This is standard Object Pascal, to embed a single quote without terminating the string.

If possible, use the parameter functions to avoid conflicts:

Qry.SQL.Text := 'UPDATE Customer SET CustName = :uName';
Qry.ParamByName('uName') := EditBox1.Text;   // note that param syntax changes depending on BDE/ADO choice.

and now it shouldn't matter if the name is O'Donnell.

Hope this helps. Otherwise, paste here the bit of code that's bothering you and we'll have a go.

there is also a quotedstr-function,
which does the double of the quotes if needed
