Hello,

I have a delphi 2k5 project with ODAC 5.8xx . I switch to the new delphi 2010 with ODAC componant 6.90.0.51. No problem.

My customer wants to use those caractere: ĀāĒēĪīŌōŪū. So I want to use unicode, I change the UseUnicode property to "True". The problem was, in execution, I have an error "EdatabaseError: Wrong type for field 'xxx' wait:String Actualy:WideString"

It is possible to make an automatic conversion of all my string fields types in my project?

My apologies for my bad english.

Regards,

Sim

You can replace TStringField with TWideStringField in *.pas and *.dfm files using a text editor that supports the Replace in Files feature.

Thank you for your answer.

I try your idea and come back tell you if it's ok or not.

Hello

I try to replace all TStringField in TWideStringField with notepad++
when I execute the project, I have an exception "EClassNotFound with message TWideStringF not found"

I search in my *.pas and *.dfm file about "TWideStringF" and I find nothing. The search and replace is ok in all my files.

thank for your help

My mistake, you can forget my previous post.

Now i have an EDatabaseError when I open query:
"Wait: WideStrind, actual: String". I check all fields declaration in .pas and .dfm, it's TWideStringField

And if I change UseUnicode propertie to False, I have this: "Wait: String, actual: WideString".

Regards,

Please recreate fields for this query.

Hi,

It's a problem in my case: I have a big projet with a lot of string field which have a lot of evenement... Unfortunatly I can't waste time for this.

Is Any convertion tools exists?

Thx

Please recreate fields for one query that does not work with automatic replacement. Then see which fields are TWideStringField and which fields are TStringField.

ok, I try your suggestion:
In the main form, I have 3 query. Two of them don't have problem. The fields are TWideStringFiled, and I can open them.
The third, I recreate the String field. The the new is TstringField but when I open it, I have an exception: Wait:WideString: Actual:String.

I don't understand!

Thank you for your help

Hello again,

I find the problem: I create an OraSession object for each form, and any of the don't have the True value for UseUnicode propertie.

Thank you very much for your time
